A freestanding tub filler rough-in kit anchors the faucet below the finished floor, so matching the rough-in to the faucet is just as important as choosing the visible trim. I’d put the Moen TS50100 first for shoppers with a compatible Moen filler, while the Delta R4700-FLWS stands out for Delta installations and the Pfister 0X6-270R gives Pfister buyers a brand-specific alternative. The main tradeoff is between a manufacturer-matched kit and a less costly compatible-style valve whose fit and included parts need closer checking. Floor structure, supply connections, and the exact faucet model can also determine whether a kit is suitable. Read on for the full comparison and guidance on choosing the right rough-in before the floor is finished.

Key Takeaways
- Brand and faucet compatibility matter more than a similar-looking model number: Moen TS-series kits, Delta R4700-FL variants, and Pfister 0X6-270R serve different faucet systems.
- The TS50100 is the strongest general Moen starting point in this lineup, but buyers should verify the exact trim model before ordering; the TS50110 and TS50210 are not automatic substitutes.
- Several Delta-oriented alternatives share the R4700-FL naming, including Delta, SQFOR, Tearel, and Golicc listings, so included parts, documentation, and seller support separate them more than the name alone.
- Floor support and access shape installation success: the Moen TS50200 is specifically described as a double-riser floor-joist mounting kit, a detail that can matter more than choosing the lowest-profile option.
- Rough-in decisions must happen before finish flooring: location, finished-floor height, pipe routing, and service access are difficult to correct once the tub filler and floor are installed.

More Details on Our Top Picks
Moen TS50100 Freestanding Tub Filler Floor Mounting Kit
I rank the TS50100 first for buyers installing a Moen single-riser filler because its adjustable bracket fits joists 12 to 24 inches apart, giving it more flexibility across common floor layouts than a fixed-spacing mount. The M-PACT system also lets you change compatible faucet styles later without replacing the in-wall or underfloor plumbing, a useful advantage if the bathroom finish plan changes. Unlike the Moen TS50210, which is meant for double-riser fillers, this kit is specifically aimed at a single-riser setup. Its included rough-in valve and bracket keep the installation package focused, but the narrow brand and faucet compatibility is a real limit: it is not a general-purpose mount for other manufacturers. I would choose it when the intended filler is Moen and the joist span fits its range.
Pros:- Expandable bracket fits joists 12 to 24 inches apart
- M-PACT design allows compatible faucet-style changes without replacing plumbing
- Includes both a floor-mount bracket and rough-in valve
- Limited lifetime warranty
Cons:- Designed for Moen freestanding single-riser fillers rather than universal compatibility
- Product data lists compression connections, so buyers should confirm those suit the planned plumbing
Best for: Homeowners installing a Moen single-riser freestanding tub filler who want adjustable joist fit and the option to update compatible faucet styling later
Not ideal for: Buyers using a non-Moen filler, a double-riser faucet, or floor joists outside the 12-to-24-inch range
- Brand:Moen
- Model:TS50100
- Included component:Floor-mount rough-in valve
- Compatible joist spacing:12–24 inches
- Inlet connection:Compression
- Outlet connection:Compression
- Thread size:1/2 inch
- Warranty:Limited lifetime
Our verdict“Choose the TS50100 for a Moen single-riser installation where adjustable joist spacing and future compatible style changes matter more than cross-brand flexibility.”
Moen TS50110 Freestanding Tub Filler Floor Mounting Kit
The TS50110 is the Moen single-riser pick I would favor when the installation plan calls for a concrete floor and a more substantial hardware package. It includes a brass rough-in valve, manifold, bracket, and mounting screws, so the key mounting pieces arrive together rather than leaving the installer to source as many components separately. Its expandable bracket also accommodates 12-to-24-inch joist spacing, much like the TS50100. The tradeoff is that this kit is heavier and its unfinished appearance is meant to disappear beneath the finished floor, not serve as a finished fixture. Like the TS50100, it is limited to Moen single-riser fillers; buyers planning a double-riser Moen faucet should compare it with the TS50210 instead.
Pros:- Brass valve and sturdy bracket support a firm floor-mount installation
- Expandable brackets fit joists 12 to 24 inches apart
- Includes manifold and mounting screws as well as the rough-in valve and bracket
- Limited lifetime warranty
Cons:- Compatibility is limited to Moen single-riser freestanding fillers
- Unfinished appearance is not intended to function as visible trim
- At 6.7 pounds, it is substantially heavier than the TS50100
Best for: Renovators installing a Moen single-riser tub filler over a concrete floor who want the bracket, manifold, and mounting screws bundled together
Not ideal for: Buyers seeking a finished visible component, a double-riser setup, or a rough-in kit for a non-Moen filler
- Brand:Moen
- Model:TS50110
- Included components:Floor-mount rough-in valve, mounting bracket, manifold, mounting screws
- Mounting:Concrete floor; expandable brackets
- Compatible joist spacing:12–24 inches
- Material:Brass
- Dimensions:5.5 × 5.5 × 3.63 inches
- Weight:6.7 pounds
- Warranty:Limited lifetime
Our verdict“Pick the TS50110 for a Moen single-riser project where bundled mounting hardware and concrete-floor installation are priorities.”
Moen TS50210 Freestanding Tub Filler Mounting Kit
For a Moen double-riser filler, the TS50210 is the more relevant choice than the TS50100 or TS50110: those two kits are specified for single-riser installations. Its expandable mounting brackets cover 12 to 24 inches between joists, while the sturdy brass bracket is intended to help limit movement at the floor-mounted faucet. The M-PACT valve system adds a practical future benefit, since compatible faucet-style updates can be made without replacing the rough plumbing. The main compromise is narrow compatibility: this is not a catch-all floor valve for other brands or Moen single-riser models. It also arrives unfinished, so the visible look comes from the selected filler, not this rough-in kit. I would match the kit to the exact faucet configuration before ordering.
Pros:- Specified for Moen double-riser freestanding tub fillers
- Expandable brackets fit joists 12 to 24 inches apart
- M-PACT system supports compatible future faucet-style updates without plumbing replacement
- Brass construction and a sturdy bracket help support a stable installation
Cons:- Limited to the intended Moen double-riser configuration
- Unfinished surface is not a finished visible faucet component
- At 8.1 pounds, it is heavier than the TS50100
Best for: Buyers fitting a Moen double-riser freestanding tub filler who need an adjustable floor mount and want compatible future style changes
Not ideal for: Owners of Moen single-riser or non-Moen fillers, and buyers who need a finished exposed component
- Brand:Moen
- Model:TS50210
- Mounting type:Floor mount
- Recommended use:Moen double-riser freestanding tub filler
- Compatible joist spacing:12–24 inches
- Material:Brass
- Dimensions:3 × 10 × 6.5 inches (D × W × H)
- Weight:8.1 pounds
- Warranty:Limited lifetime
Our verdict“Choose the TS50210 when your exact Moen filler is double-riser; for Moen single-riser models, the TS50100 or TS50110 is the better match.”
R4700-FLWS Rough-In Valve for D Floor-Mount Freestanding Tub Filler
The R4700-FLWS stands apart from the Moen TS50100, TS50110, and TS50210 because it is a rough-in valve for a D floor-mount filler, not a Moen mounting kit organized around joist spacing and riser type. Its brass construction, screwdriver service stops, test plugs, and plasterguard suit projects where the valve goes in before the final trim choice. It can be installed on surfaces up to 2.5 inches thick, including concrete, which gives remodelers a useful slab-related specification. That flexibility does not make it universal: it is tied to the specified D filler, and the trim kit is sold separately. Buyers should also confirm the listed soldered connections and unusual thread-size data with the installation documentation before planning the pipework.
Pros:- Brass valve body
- Screwdriver service stops allow shutoff at the valve
- Includes test plugs, plasterguard, and cartridge
- Specified for surfaces up to 2.5 inches thick, including concrete
Cons:- Compatible only with the specified D floor-mount freestanding tub filler
- Trim kit is sold separately
- Soldered connections may not suit every planned plumbing setup
Best for: Contractors or remodelers installing the compatible D floor-mount filler who need a brass valve for a surface up to 2.5 inches thick and want service stops
Not ideal for: Buyers who have not selected a compatible D filler, want a complete trim-and-valve package, or need a Moen-specific joist-mount kit
- Brand:Tearel
- Model:R4700-FLWS
- Material:Brass
- Inlet connection:Soldered
- Outlet connection:Soldered
- Number of ports:2
- Maximum surface thickness:2.5 inches
- Dimensions:9.8 × 5.3 × 8 inches
- Included components:Rough-in valve, test plugs, plasterguard, cartridge
Our verdict“Choose this valve for a compatible D filler installation that needs service stops and slab-thickness flexibility, but budget for separate trim.”
SQFOR R4700-FL Floor-Mount Rough-In Valve for Delta Freestanding Tub Faucets
The SQFOR R4700-FL is the lineup’s stainless-steel rough-in option for specified Delta floor-mount tub and shower faucets, giving it a different material profile from the brass Moen TS50110 and Tearel R4700-FLWS. Its listed maximum slab thickness of 2.5 inches makes it relevant to concrete-floor planning, and the product description says it can be replaced from above the floor. That access claim may appeal to buyers trying to limit future floor disruption, but I would confirm the exact service procedure and faucet compatibility before relying on it. The package includes only the valve and manual; trim is not included. Compared with the Tearel valve, this one is aimed at Delta compatibility and uses stainless steel, but the available data lists fewer included service components.
Pros:- Stainless-steel construction
- Specified for Delta floor-mount tub and shower faucets
- Fits slabs up to 2.5 inches thick
- Description says the valve can be replaced from above the floor
Cons:- Trim kit is not included
- Compatibility is limited to the specified Delta faucets
- Package lists only the valve and manual, with fewer included components than the Tearel R4700-FLWS
Best for: Delta faucet owners planning a floor-mount installation who prefer a stainless-steel rough-in valve and have a slab no thicker than 2.5 inches
Not ideal for: Buyers with Moen or D-series fillers, anyone needing trim included, or installers who require a broader list of included service parts
- Brand:SQFOR
- Model:R4700-FL
- Material:Stainless steel
- Finish:Silver
- Mounting type:Floor mount
- Compatible faucets:Delta floor-mount tub and shower faucets
- Maximum slab thickness:2.5 inches
- Dimensions:6.77 × 5.78 × 5.3 inches
- Included components:Rough-in valve and manual
Our verdict“Choose the SQFOR valve for a compatible Delta floor-mount faucet when stainless steel and the stated slab limit suit the project, and source trim separately.”
Tearel R4700-FL Rough-In Valve for D Floor-Mount Freestanding Tub Fillers
The Tearel R4700-FL is a strong fit when you need a compatible D floor-mount filler and want room to adjust the valve from above the floor. Its 2.5-inch surface-thickness limit and included test plugs and plasterguard help define the rough-in before the finished fixture is selected or installed. The machined brass body and stainless steel plate give it a more clearly specified material package than the general metal construction listed for the Pfister 0X6-270R. That advantage only matters if your filler is compatible: Tearel identifies a specific D-style fit, not broad cross-brand support. The compression connections and two ports also make matching the plumbing plan important. Choose it for adjustment access and documented components; skip it if your tub filler is from another system or you need a stated floor-thickness allowance above 2.5 inches.
Pros:- Machined brass body paired with a stainless steel mounting plate
- Valve can be adjusted from above the floor
- Supports surfaces up to 2.5 inches thick
- Includes test plugs, plasterguard, and cartridge
Cons:- Compatibility is limited to D floor-mount freestanding tub fillers
- The stated surface-thickness allowance is lower than Delta R4700-FLWS’s listed 3-inch maximum
- Compression connections may not suit every planned plumbing setup
Best for: Buyers installing a compatible D floor-mount tub filler who want above-floor adjustment access and included rough-in protection parts.
Not ideal for: Shoppers using a Pfister, Delta, or other unconfirmed filler system, or projects with a finished surface thicker than 2.5 inches.
- Model:R4700-FL
- Material:Machined brass body; stainless steel mounting plate
- Compatibility:D floor-mount freestanding tub fillers
- Maximum surface thickness:2.5 inches
- Connections:Compression inlet and outlet
- Ports:2
- Valve type:Gate valve
- Dimensions:9.8 x 5.9 x 3.2 inches
- Certifications:CSA, NSF, ULC, UPC
Our verdict“Choose the Tearel when your filler is confirmed compatible and above-floor adjustment is a priority, but not when you need broader brand fit.”
Pfister 0X6-270R Freestanding Tub Filler Rough-In Valve
For a project already centered on a Pfister freestanding tub filler, the 0X6-270R keeps the choice straightforward: it is a floor-mounted valve made for Pfister fillers, with integral stops and mounting hardware included. Those stops give the installer shutoff control at the rough-in, while the included hardware avoids sourcing a separate mounting set. Compared with the Delta R4700-FLWS, Pfister’s listing does not specify a brass body, stainless steel plate, or maximum floor thickness, so buyers have less material and fit information to check before installation. Its unfinished metal construction is also functional rather than a finished trim feature. This makes the Pfister a focused fit for brand-matched renovations, not a flexible substitute for another manufacturer’s rough-in. Confirm the exact filler model and plumbing connections before choosing it.
Pros:- Designed for Pfister freestanding tub fillers
- Integral stops provide shutoff control at the valve
- Mounting hardware is included
- Metal construction with a limited lifetime warranty
Cons:- Designed for Pfister fillers rather than broad cross-brand compatibility
- Listing does not state a maximum floor thickness
- Unfinished appearance offers no finished trim or faucet on its own
Best for: Homeowners and installers fitting a compatible Pfister freestanding tub filler who want integral stops and included mounting hardware.
Not ideal for: Buyers using Delta or other-brand fillers, or those who need published floor-thickness and detailed body-material specifications.
- Model:0X6-270R
- Material:Metal
- Mounting:Floor-mounted
- Inlet connection size:0.5 inches
- Thread type:Threaded
- Valve type:Ball valve or gate valve
- Dimensions:7.86 x 6.88 x 5.3 inches
- Weight:3.4 pounds
- Warranty:Limited lifetime
Our verdict“Pick the 0X6-270R for a confirmed Pfister filler installation with integral stops, and pass if your project needs another brand’s valve.”
Delta R4700-FLWS Freestanding Tub Filler Rough-In Valve
The Delta R4700-FLWS earns its place for projects where the finished floor may be thicker than the allowance listed for several comparable valves. Delta specifies support for floors up to 3 inches thick, compared with 2.5 inches for the Golicc R4700-FL and Tearel R4700-FL. Its machined brass body, stainless steel mounting plate, screwdriver stops, test caps, and plasterguard make the rough-in package clearly defined. It also lets you select the faucet trim and finish later, which can help when finish decisions lag behind plumbing work. The main limitation is brand fit: this valve is for Delta freestanding tub fillers, and the trim and faucet are sold separately. Choose it when floor thickness and staged finish selection matter; the Golicc is a closer alternative if your floor is within 2.5 inches and you want an R4700-series replacement.
Pros:- Listed for finished floors up to 3 inches thick
- Machined brass body and stainless steel mounting plate
- Screwdriver stops, test caps, and plasterguard are included
- Allows trim and finish selection after rough-in installation
Cons:- Designed for Delta freestanding tub fillers
- Faucet and trim kit are sold separately
- Its floor-thickness advantage may be unnecessary for floors within the Golicc’s 2.5-inch limit
Best for: Delta filler buyers whose finished floor may reach 3 inches thick or who need to install the rough-in before choosing faucet trim.
Not ideal for: Buyers with non-Delta fillers or anyone expecting the rough-in purchase to include the faucet and trim kit.
- Model:R4700-FLWS
- Mounting type:Floor-mount, single-hole
- Materials:Brass body; stainless steel mounting plate
- Maximum floor thickness:Up to 3 inches
- Mounting hole diameter:1.5 inches
- Included components:Installation hardware, test caps, plasterguard
- Item weight:7.8 pounds
- Warranty:Lifetime limited faucet and finish warranty
Our verdict“Choose the Delta R4700-FLWS when you need its 3-inch floor allowance or want to defer trim selection, provided your filler is Delta-compatible.”
Golicc R4700-FL Freestanding Tub Filler Rough-In Valve
The Golicc R4700-FL is aimed at buyers replacing or matching Delta R4700-FL and R4700 assemblies, rather than anyone shopping for a universal tub-filler valve. Its brass body and stainless steel mounting plate, two compression-connected ports, and included test plugs and plasterguard make the core rough-in details easy to verify. Like the Tearel R4700-FL, it supports above-floor adjustment and a 2.5-inch finished-floor maximum; unlike Tearel, its stated compatibility points to Delta fillers and named R4700 assemblies. That fit makes it useful for a specific repair or replacement path, though it is narrower than the Delta R4700-FLWS, which lists a 3-inch floor allowance. The listing does not include a faucet or trim, so check the assembly match and floor depth before ordering.
Pros:- Specified for Delta freestanding tub fillers and R4700-FL/R4700 assemblies
- Brass valve body with stainless steel mounting plate
- Allows adjustment from above the finished floor
- Includes test plugs and plasterguard
Cons:- Compatibility is limited to Delta fillers and specified R4700 assemblies
- Maximum finished-floor thickness is 2.5 inches, below the Delta R4700-FLWS allowance
- Faucet and trim are not listed as included
Best for: Delta tub-filler owners replacing an R4700-FL or R4700 assembly on a finished floor no thicker than 2.5 inches.
Not ideal for: Buyers with non-Delta fillers, floors thicker than 2.5 inches, or projects needing a supplied faucet or trim kit.
- Model:R4700-FL
- Material:Brass valve body; stainless steel mounting plate
- Compatibility:Delta freestanding tub fillers; R4700-FL and R4700 assemblies
- Maximum finished-floor thickness:2.5 inches
- Ports:2
- Connections:Compression inlet and outlet
- Dimensions:5.31 x 5.9 x 6.3 inches
- Weight:2.2 pounds
- Included components:Valve body, mounting plate, test plugs, plasterguard
Our verdict“Choose Golicc for a compatible Delta R4700-series replacement under a 2.5-inch floor, but use the Delta R4700-FLWS for a thicker floor.”
Floor-Mount Freestanding Tub Filler Rough-In Valve for Delta R4700-FLWS with Screwdriver Stops, Chrome
This E-cowlboy valve is the lineup’s chrome-finish alternative for buyers matching a Delta R4700-FLWS installation. Its screwdriver stops are intended to give the installer controlled shutoff access, while the metal construction and brass handle distinguish it from the more fully specified brass-body Delta R4700-FLWS. The comparison matters: Delta lists a stainless steel mounting plate, test caps, plasterguard, and a 3-inch floor allowance; those details are not provided for this E-cowlboy model. In return, the chrome finish gives the valve a stated finish option, though the product is still a rough-in component rather than a complete tub filler. Compatibility is specifically tied to the R4700-FLWS, so this is not a general-purpose substitute for the Pfister 0X6-270R or Tearel R4700-FL.
Pros:- Specifically identified for Delta R4700-FLWS fillers
- Screwdriver stops offer installer shutoff control
- Chrome finish is specified
- Metal construction with a brass handle
Cons:- Compatibility is limited to the specified Delta model
- Product data does not state a maximum floor thickness or include rough-in protection parts
- A rough-in valve alone does not supply the tub filler or trim
Best for: Buyers seeking a chrome-finish rough-in valve specifically for a Delta R4700-FLWS-compatible freestanding tub filler.
Not ideal for: Shoppers who need clearly listed floor-thickness limits, a specified stainless steel mounting plate, or compatibility beyond the Delta R4700-FLWS system.
- Model number:EC – R4700-FLWS
- Manufacturer part number:EC – R4700-FLWS
- Mounting type:Floor mount
- Compatibility:Delta R4700-FLWS freestanding tub fillers
- Material:Metal; brass handle
- Color:Chrome
- Item weight:4.52 kg
- Unit count:1
Our verdict“Consider this E-cowlboy option for a confirmed R4700-FLWS setup when chrome finish matters, but favor Delta’s listed valve if you need fuller fit specifications.”
TS50100 Freestanding Tub Filler Floor Mounting Kit for Moen Faucets
I’d shortlist this kit when the planned fixture is a compatible Moen one-handle freestanding tub filler and the floor framing calls for adaptable bracket placement. Its bracket adjusts from 12 to 24 inches, giving more flexibility across joist layouts than a fixed-position setup. The solid brass construction and included manifold and screws make it a more complete mounting package than the Delta R4700-FL, which is designed around Delta fillers instead. Its M-PACT compatibility also supports later changes to compatible faucet trim without replacing the rough-in. The tradeoff is a narrow brand and faucet fit: this is not a universal valve, and the specified one-year warranty is shorter than the lifetime coverage listed for the Delta and Moen TS50200 kits.
Pros:- Solid brass construction is suited to resisting corrosion and wear in a floor rough-in.
- Adjustable bracket spans 12 to 24 inches for varied joist spacing.
- Includes a manifold and mounting screws alongside the bracket.
- M-PACT compatibility can allow future changes to compatible faucet trim.
Cons:- Compatibility is limited to Moen one-handle freestanding tub filler faucets.
- The stated warranty is one year, shorter than the lifetime warranties listed for the Delta R4700-FL and Moen TS50200.
- The product data does not specify a maximum floor-surface thickness.
Best for: Renovators installing a compatible Moen one-handle filler who need adjustable 12-to-24-inch bracket spacing and want the option to change M-PACT trim later.
Not ideal for: Buyers using Delta or other non-compatible faucets, or those who prioritize a longer stated warranty over adjustable bracket spacing.
- Manufacturer:semkalo
- Model:LS53-TS50100
- Material:Solid brass
- Color:Gold
- Bracket adjustment:12 to 24 inches
- Compatibility:Moen one-handle freestanding tub filler faucets
- Included components:Mounting bracket, manifold, and mounting screws
- Warranty:1 year
Our verdict“Choose this kit for a compatible Moen one-handle filler when adjustable joist spacing matters more than broad brand compatibility or longer warranty coverage.”
Delta R4700-FL Freestanding Tub Filler Rough-In Valve
For a Delta freestanding filler installation, this is the strongest fit in the group when the floor assembly is unusually thick. The single-hole, floor-mount valve supports surfaces up to 2.5 inches thick, including concrete, a clearly stated allowance that the Moen TS50100 and TS50200 descriptions do not provide. Its machined brass body and stainless steel mounting plate address the durability and support needs below the finished floor, while included test caps and a plasterguard help protect the rough-in during construction. I’d favor it over the Moen TS50100 for a Delta fixture, but its brand-specific compatibility cuts both ways: it is not the flexible choice for a Moen faucet. The lifetime limited warranty is a plus, though the faucet itself is sold separately.
Pros:- Accepts floor surfaces up to 2.5 inches thick, including concrete.
- Machined brass body and stainless steel mounting plate provide substantial rough-in materials.
- Test caps and a plasterguard are included for the construction phase.
- Lifetime limited warranty is specified.
Cons:- Designed for Delta freestanding tub fillers, limiting cross-brand use.
- Faucet is sold separately.
- The product data does not specify adjustable joist spacing.
Best for: Homeowners and contractors installing a Delta freestanding tub filler through a thick floor assembly or concrete surface.
Not ideal for: Buyers installing a Moen or other non-Delta filler, or anyone expecting the rough-in package to include the faucet.
- Brand:Delta
- Model:R4700-FL
- Installation:Single-hole, floor-mount
- Maximum surface thickness:2.5 inches
- Body material:Machined brass
- Mounting plate material:Stainless steel
- Flow rate:6 gpm
- Included components:Test caps and plasterguard
- Warranty:Lifetime limited warranty
Our verdict“Pick the R4700-FL for a Delta filler when thick-floor compatibility is the deciding factor, but not for a Moen fixture or an all-in-one purchase.”
Moen TS50200 Freestanding Floor Mount Tub Filler Double Riser Floor Joist Mounting Kit
The TS50200 is the specialist choice here: it is built for a double-riser freestanding tub filler, not simply a generic floor-mount connection. Its expandable brackets fit joists spaced 12 to 24 inches, and the stated goal of a sturdy, wobble-free mount addresses a practical concern with tall floor-standing fixtures. Like the TS50100, it uses Moen’s M-PACT system for future compatible faucet-style changes; unlike the TS50100 listing, it specifically identifies double-riser mounting and carries a limited lifetime warranty. The Delta R4700-FL is the better match for Delta fillers and thick surfaces up to 2.5 inches, but it does not share this kit’s stated double-riser and adjustable-joist focus. Brand-specific compatibility and potentially complex installation make professional planning sensible.
Pros:- Designed specifically for a double-riser freestanding tub filler.
- Expandable brackets accommodate 12-to-24-inch joist spacing.
- M-PACT compatibility supports later changes to compatible faucet styles.
- Limited lifetime warranty is specified.
Cons:- Requires a compatible Moen M-PACT faucet, limiting use with other brands.
- Installation may be complex for DIY users and may call for professional help.
- The supplied product data includes conflicting mounting details, so buyers should confirm the exact installation configuration before purchase.
Best for: Moen-focused bathroom remodelers installing a double-riser floor-mounted filler across joists spaced 12 to 24 inches.
Not ideal for: Buyers with a Delta or other non-M-PACT faucet, or DIY installers who need a clearly simple installation and lack plumbing experience.

Our verdict“Choose the TS50200 for a compatible Moen double-riser filler when adjustable joist mounting and long warranty coverage outweigh installation simplicity.”
How We Picked
I ranked these options around the decision that matters most for a rough-in kit: whether it is designed for the buyer’s faucet and installation. I gave priority to clear brand and model identification, stated floor-mount or joist-mount purpose, and the potential to make a pre-finish installation predictable. The Moen TS50100 and Delta R4700-FLWS lead their respective brand groups because their listings identify a specific manufacturer system; Pfister’s 0X6-270R provides a distinct brand-matched path rather than another Delta-pattern listing.
I treated the remaining options as conditional picks, not interchangeable bargains. Similar or duplicated model names make it harder to judge fit from a listing alone, so I ranked those lower unless a buyer can confirm compatibility, included components, and installation instructions with the manufacturer or seller. Build and floor attachment, documentation, maintenance access, and replacement-part confidence all matter here; a low-cost kit offers little value if it does not suit the faucet or the floor assembly. I did not infer performance or compatibility beyond the product names and stated descriptions.
Factors to Consider When Choosing Freestanding Tub Filler Rough In Kit
Choose the rough-in as part of the plumbing and floor plan, not as an accessory to buy after selecting the faucet. These broader checks can prevent a mismatch that is expensive to fix once the floor is closed.
Match the rough-in to the exact faucet model
Start with the faucet’s installation instructions and identify the required rough-in model by its full part number. A shared brand name or similar R4700-FL wording does not prove that two products are interchangeable. Check whether the faucet calls for a specific valve, mounting kit, riser arrangement, or included connection set. If you are replacing only the rough-in, confirm that the existing visible faucet trim is designed for it. Ask the manufacturer or seller to confirm compatibility in writing when the listing is ambiguous; guessing can leave you with a sealed-in part that cannot support the faucet.
Plan for the finished-floor height
Rough-in placement is measured against the floor that will be finished, not just the subfloor visible during early construction. Tile, stone, underlayment, and waterproofing can change the final height and affect how the faucet sits or how the mounting hardware engages. Use the installation sheet’s height references and coordinate them with the flooring plan before securing the assembly. A common mistake is to locate the valve from a preliminary floor measurement and discover that the finished surface alters the intended fit. When floor materials are undecided, resolve the build-up with the installer before plumbing work begins.
Check joist support and pipe routing
A floor-mounted filler needs a stable connection to the floor structure, not merely a hole cut to fit the pipe. Check joist direction, spacing, and the kit’s mounting method before selecting the final tub position. A double-riser or joist-mount arrangement may suit some framing plans, while other installations may call for a different support strategy. Confirm that supply lines can reach the rough-in without awkward bends or clashes with joists, drains, or other services. If the planned location falls between structural members, arrange suitable blocking rather than improvising support after the floor is open.
Compare what is included, not just the model name
Listings can describe similar rough-in valves while differing in mounting hardware, stops, connectors, or documentation. Read the parts list and installation guide to see what must be purchased separately and whether the kit includes the components your plumber expects. This matters especially when comparing Delta-oriented alternatives with the same R4700-FL family wording. A low-cost listing may be a sensible choice if the parts and compatibility are clearly confirmed; it is a poor shortcut if you need to source missing hardware later. Keep the packaging and model information until installation is complete so any mismatch can be resolved before the floor is closed.
Preserve service access and plan testing
Although the rough-in sits beneath the finished faucet, plumbing connections still need a sensible route for inspection and service. Follow the product instructions for access, shutoff placement, and connection testing instead of assuming the finished assembly will conceal every issue. Have the installer pressure-test the supply lines and check for leaks before flooring or trim blocks access. Photograph the rough-in and supply routing while the floor is open; those records can help with later repairs. Spending time on this step is usually more useful than paying extra for a kit whose added features do not match your installation.
Decide when brand matching is worth the extra effort
A manufacturer-matched kit is often the clearest choice when you want direct documentation and a straightforward compatibility check. A third-party option may suit a buyer who has verified the exact faucet fit and confirmed the supplied parts with the installer. The tradeoff is not simply brand name versus savings: it is the value of clearer support against the time and risk of validating an alternative. For a new build or a floor that will be difficult to reopen, favor certainty and documented fit. For a serviceable installation with a confirmed specification, a compatible alternative can be reasonable.
Frequently Asked Questions
Can I use any R4700-FL rough-in valve with a Delta freestanding tub filler?
No; the shared model-family wording is not enough to confirm fit. Compare the exact faucet model with the rough-in instructions and parts list, including any suffix such as FLWS. Third-party listings from SQFOR, Tearel, or Golicc may describe compatibility with Delta faucets, but you should verify the specific trim and supplied components before purchase. Ask Delta or the seller to confirm the pairing if the documentation does not name your faucet. Make that check before plumbing or flooring work starts.
Should I buy the rough-in kit before or after choosing the tub filler?
Choose the tub filler first, or select both together, because the faucet instructions determine the required rough-in. Buying a kit based only on appearance or brand can create a mismatch even when the products seem intended for the same style of installation. Once you have the faucet model, confirm its required rough-in part number and floor-mount details. You can still purchase early for project scheduling, but keep the model information available to the plumber and verify it against the final faucet selection. Avoid closing the floor until the parts have been checked.
What should I verify before the floor is closed?
Confirm that the rough-in is in the specified location and set for the planned finished-floor height. Check that its mounting is secure, the supply connections match the instructions, and the pipe route does not conflict with joists or other plumbing. Have the lines tested for leaks while the assembly remains accessible. Compare the installed part number with the faucet documentation and confirm that any required stops or hardware are present. Take photos of the work and keep them with the project records before the flooring covers the installation.
Is a third-party Delta-compatible rough-in a sensible alternative?
It can be, provided compatibility is confirmed for the exact faucet and the listing clearly identifies what comes in the box. Compare the supplied parts and instructions with the Delta R4700-FLWS documentation rather than relying on a similar product title. Consider how you will handle installation questions or replacement parts if the kit differs from the manufacturer-branded option. For a floor that will be difficult to reopen, I would favor the clearest documented match. A third-party option makes more sense when the installer has verified fit and the project can resolve any parts issue before finish work.
Do I need a double-riser floor-joist mounting kit?
Only if the faucet instructions and floor framing call for that arrangement. The Moen TS50200 is identified as a double-riser floor-joist mounting kit, so its stated purpose is more specific than a general floor-mount kit. Check joist placement, the faucet model, and the required support method before choosing it. Do not assume that a double-riser setup is automatically stronger or more suitable for every tub location. If the framing does not match the kit’s installation requirements, ask a plumber or the manufacturer about an appropriate support plan.
Conclusion
For most buyers who have selected a compatible Moen faucet, I’d start with the Moen TS50100 as the best overall because its model identity is clear and it serves as a straightforward brand-matched choice. The best value depends on confirmed fit: compare the Delta R4700-FL alternatives only after checking the exact faucet, included hardware, and seller documentation rather than choosing by name alone. For a best premium or lowest-uncertainty route, favor the manufacturer-specific rough-in that the faucet instructions name; the lineup does not establish a universal premium winner across brands. The best choice for beginners is the exact Moen or Delta kit specified by the faucet manual, since reducing compatibility guesswork matters more than comparing similar listings. For specific floor-framing needs, investigate the Moen TS50200 double-riser joist kit, while Pfister owners should check the 0X6-270R against their faucet documentation. Before ordering any option, confirm the model pairing, floor height, support, and parts list with your installer.
