I’ve focused this roundup on a choice that matters more than finish alone: how much of the shower you need to control and whether you’re buying a valve, a controller, or both. My best overall pick is the Moen S3104 for a four-outlet layout, while the Moen S3102 is a more compact match for two fixtures. For buyers who already have the right valve, the TS3304TB controller adds four-outlet presets, voice control, and a warm-up pause feature.

These five products are components in Moen’s U by Moen system, not five complete, interchangeable shower kits. The valves manage water and require a compatible controller; the controllers provide the user interface and require a compatible thermostatic valve. I rank them by how clearly each component fits a particular bathroom plan, the amount of control it supports, and the practical tradeoffs around compatibility, connectivity, and buying the matching hardware. Outlet capacity, system completeness, and installation compatibility are the main differences to weigh.
Complete the kit
Key Takeaways
For a four-outlet shower: Pair the S3104 valve with the TS3304TB controller; the valve alone is not a complete smart shower system.
For two fixtures in a compact wall: The S3102 offers two outlets, standard 1/2-inch connections, and a 30-foot data cable, but still needs a compatible controller.
For app and voice control: The TS3302BL, TS3302TB, and TS3304TB controllers support listed voice assistants and the U by Moen app, subject to system setup and connectivity.
For matching an existing valve: The controller choice depends on the required valve and outlet count; the TS3302 models specify the S3102, while the TS3304TB is a four-outlet controller.
Before planning the build: Check outlet count, pipe connection size, controller compatibility, Wi-Fi needs, and whether the valve and controller are sold separately.

More Details on Our Top Picks
Moen Smart Shower 4-Outlet Digital Thermostatic Valve, 3/4-Inch Connections, S3104
The S3104 is my leading valve pick for a shower plan that needs up to four outlets. Compared with the two-outlet S3102, it leaves room to coordinate more fixtures through a compatible U by Moen controller—useful when a design combines a showerhead, hand shower, and additional outlets. That capacity is the main reason it ranks first here; buyers who only need two fixtures may not benefit from the larger configuration.
It is a valve, not a complete smart shower system. A compatible controller is sold separately, so I’d treat this as the plumbing-side part of a matched setup and confirm controller compatibility before committing. The 30-foot data cable offers flexibility in where the controller can sit relative to the valve, and the stated standard 2×4 wall fit can help with planning a conventional wall cavity. The 3/4-inch CC connections are a meaningful distinction from the S3102’s 1/2-inch connections: buyers need to check that their plumbing plan suits the larger connection size rather than assuming the models are direct substitutes.
The valve is described as maintaining a consistent water temperature, which is central to a thermostatic system. Its drawback is less about its stated function than the cost and coordination of the full build: the controller is not included, and the supplied details do not identify a controller in the box. Compared with buying one of the digital controllers alone, this makes the S3104 the right starting point only for shoppers who are still selecting the valve side of a four-outlet system.
Pros:- Supports up to four outlets for a multi-fixture shower plan.
- Maintains consistent water temperature.
- Fits a standard 2×4 wall, according to the supplied specifications.
- Includes a 30-foot data cable for flexible controller placement.
Cons:- Compatible U by Moen controller is sold separately.
- 3/4-inch connections may not suit plans built around the S3102’s 1/2-inch connections.
- The valve alone does not provide the controller’s presets, display, or smart interface.
Best for: Homeowners planning a four-outlet shower who need a thermostatic valve and will select a compatible controller separately.
Not ideal for: Buyers who need a complete ready-to-install system, only want two outlets, or cannot use 3/4-inch CC connections in their plumbing plan.
- Brand:Moen
- Model:S3104
- Outlets:4
- Connections:3/4-inch CC inlet and outlet
- Installation:Fits standard 2×4 wall
- Data cable:30 feet
- Weight:6 pounds
- Warranty:5 years on digital components
Our verdict“I’d choose the S3104 as the strongest valve starting point for a four-outlet smart shower, provided the separate controller and 3/4-inch plumbing connections fit the project.”
Moen S3102 2-Outlet Digital Thermostatic Shower Valve
For a two-fixture layout, the S3102 is the more focused valve than the four-outlet S3104. It supports two fixtures, such as a showerhead and hand shower, while its 1/2-inch CC connections distinguish it from the S3104’s 3/4-inch plumbing. That makes it a sensible match for a simpler plan, but buyers should choose based on their plumbing and intended outlets rather than assuming that the smaller model is automatically the easier retrofit.
The valve is designed to maintain a consistent shower temperature and fits a standard 2×4 wall. Its 30-foot data cable gives the installer flexibility in controller placement, a practical detail when the control location and valve location are separated by wall framing or bathroom layout. It works with compatible U by Moen controllers, including the listed four-outlet controller models, which are sold separately. Because this valve has two outlets, I’d confirm the exact controller setup and intended configuration with the project plan rather than buying by brand name alone.
Compared with the S3104, the S3102 gives up outlet capacity in exchange for a more compact, two-outlet role and smaller stated connection size. Compared with the TS3302 controllers, it handles the plumbing side but does not give the user a display, presets, or voice control by itself. The installation environment also matters: the supplied product details say it must be installed where temperatures stay between freezing and 104°F. My main reservation is that a buyer has to coordinate separate components, so this is a better fit for someone assembling a system than someone seeking a one-box purchase.
Pros:- Supports two fixtures, including a showerhead and hand shower.
- Designed to maintain consistent water temperature.
- Compact design fits a standard 2×4 wall.
- Includes a 30-foot data cable for placement flexibility.
Cons:- Compatible controller is sold separately.
- Installation location must stay between freezing and 104°F.
- Two outlets offer less room for expansion than the S3104.
Best for: Buyers planning a two-outlet shower who want the valve component with 1/2-inch CC connections and a standard 2×4 wall fit.
Not ideal for: Those planning four outlets, looking for a controller included in the box, or installing where the specified temperature conditions cannot be met.
- Brand:Moen
- Model:S3102
- Outlets:2
- Inlet connections:1/2-inch CC
- Outlet connections:1/2-inch CC
- Data cable:30 feet
- Compatible controllers:U by Moen TS3304TB and TS3304BL four-outlet controllers
- Weight:1.5 pounds
- Warranty:5 years on digital components
Our verdict“I’d pick the S3102 over the S3104 for a two-fixture shower with a compatible controller and plumbing that matches its 1/2-inch connections.”
Moen Terra Beige Smart Shower 4-Outlet Digital Controller (TS3304TB)
The TS3304TB is the controller I’d shortlist for a multi-fixture setup that needs control over as many as four outlets. Its 5-inch LCD and soft-touch buttons provide a direct control point, while voice support for Alexa, Siri/HomeKit, and Google Assistant plus the U by Moen app adds hands-free and phone-based options. Compared with the TS3302 controllers, its defining advantage is outlet capacity, not a different style of temperature control.
Its warm-up and pause feature is particularly relevant to a smart shower: the controller can pause water flow while the system reaches the selected temperature, helping limit water running unused during warm-up. That function makes the TS3304TB more than a decorative digital panel, though it depends on a compatible thermostatic valve and a functioning setup. The product details also call out Wi-Fi and a compatible smart device for full functionality, so shoppers wanting connected features should check that their bathroom setup and network can support them.
This is not a standalone controller-and-valve kit. A compatible Moen thermostatic valve is sold separately, and the listed S3104 is the four-outlet valve in this roundup. The supplied information also identifies S3102 compatibility with TS3304TB, so the two-outlet valve can be part of a compatible pairing; buyers should still confirm the planned outlet configuration. Compared with the S3104, the TS3304TB supplies the user-facing controls rather than the plumbing hardware. The Terra Beige finish is a visual choice, but I’d rank capacity and system compatibility above color when choosing it.
Pros:- Controls up to four shower fixtures.
- 5-inch LCD and soft-touch buttons provide on-panel control.
- Supports Alexa, Siri/HomeKit, Google Assistant, and the U by Moen app.
- Warm-up pause feature can limit water flow while the shower heats.
Cons:- Requires a compatible Moen thermostatic valve sold separately.
- Full functionality depends on Wi-Fi and a compatible smart device.
- Four-outlet capacity may be unnecessary for a simpler shower than a two-outlet controller suits.
Best for: Buyers who want a four-outlet digital control panel, presets, listed voice-assistant support, and the warm-up pause feature in a compatible Moen system.
Not ideal for: Shoppers without a compatible thermostatic valve, those who need a two-outlet controller, or anyone who cannot provide the connectivity required for full smart functionality.
- Brand:Moen
- Model:TS3304TB
- Outlets:4
- Finish:Terra Beige
- Display:5-inch LCD
- Controls:Soft-touch buttons
- Connectivity:Alexa, Siri/HomeKit, Google Assistant, and U by Moen app
- Valve requirement:Compatible Moen thermostatic valve sold separately
- Warranty:Limited lifetime warranty
Our verdict“I’d choose the TS3304TB when a compatible valve and four-outlet control matter more than keeping the system to two fixtures.”
Moen Terra Beige 2-Outlet Digital Shower Controller, TS3302TB
The TS3302TB is the two-outlet control-panel choice for buyers who prefer Terra Beige and want digital adjustments, presets, and app or voice access. Its 5-inch LCD and soft-touch buttons give users a local way to set water temperature and power; the listed compatibility also includes Alexa, Siri/HomeKit, Google Assistant, and the U by Moen app. Compared with the four-outlet TS3304TB, it is better matched to a simpler two-fixture plan, rather than a layout built around multiple shower outlets.
The warm-up pause function can stop water flow while the shower heats to the selected temperature, which gives this controller a useful water-conscious feature alongside its smart controls. It requires a separately sold thermostatic valve, and the supplied product details say it requires a thermostatic digital valve without naming a specific model. That means I would confirm the exact valve pairing before ordering. The two-outlet S3102 is the natural match by outlet count, but compatibility should be verified rather than inferred from the count alone.
Compared with the TS3302BL, the main stated difference is finish: the black model specifies the S3102 valve requirement and a limited lifetime warranty, while this Terra Beige model lists a five-year warranty on digital components. Those details make the product records different enough that I’d check current documentation for the exact model and warranty terms before purchase. Neither controller includes the valve, so a buyer comparing these panels should consider the finish, confirmed pairing, and warranty wording—not expect one to become a complete system on its own.
Pros:- Controls two outlets and supports presets.
- 5-inch LCD and soft-touch controls provide on-panel adjustments.
- Supports listed voice assistants and the U by Moen app.
- Warm-up pause feature can stop flow while water heats.
Cons:- Thermostatic digital valve is sold separately.
- The supplied details do not specify an exact compatible valve model.
- Offers less outlet capacity than the TS3304TB.
Best for: Buyers building a two-outlet Moen digital shower who want a Terra Beige controller with presets, app and voice compatibility, and a warm-up pause feature.
Not ideal for: Those needing four outlets, buying a complete valve-and-controller kit, or unable to verify which thermostatic valve is compatible.
- Brand:Moen
- Model:TS3302TB
- Outlets:2
- Finish:Terra Beige
- Display:5-inch LCD
- Controls:Soft-touch buttons and presets
- Compatibility:Alexa, Siri/HomeKit, Google Assistant, and U by Moen app
- Valve requirement:Thermostatic digital valve sold separately
- Warranty:5 years on digital components
Our verdict“I’d choose the TS3302TB for a two-outlet Terra Beige control panel after confirming its valve pairing and the warranty terms for the exact model.”
Moen Matte Black Smart Shower 2-Outlet Digital Controller, TS3302BL
The TS3302BL is a two-outlet controller with a clearly stated S3102 pairing, which makes its compatibility details more specific than the TS3302TB’s supplied description. For buyers building around the S3102 valve, that explicit match can simplify component selection. The 5-inch LCD, soft-touch buttons, presets, and precise temperature adjustment cover the everyday control role; Alexa, Siri/HomeKit, Google Assistant, and the U by Moen app add connected options.
Its warm-up pause function can hold water flow until the selected temperature is ready, an appealing feature for anyone who dislikes letting the shower run while it heats. But this controller is not a touchscreen; it uses soft-touch buttons alongside the LCD. That may be a positive for buyers who prefer clear physical button areas, yet shoppers expecting touch navigation should know the interface is different. It also depends on the S3102 valve, which is sold separately, so the panel alone cannot control a plumbed shower.
Compared with the Terra Beige TS3302TB, this model’s standout difference is matte black styling and named valve compatibility, not a larger outlet count or a distinct smart platform. Compared with the TS3304TB, it is intended for two outlets rather than four. The supplied warranty is a limited lifetime warranty, while the TS3302TB lists five years on digital components; because the records differ, I would check the warranty applying to the specific product before purchase. This makes the TS3302BL a focused match for a two-outlet S3102 build, not the default pick for every Moen smart shower.
Pros:- Explicitly requires the Moen S3102 thermostatic valve.
- Controls two outlets and supports presets.
- Works with listed voice assistants and the U by Moen app.
- Warm-up pause function can stop flow until water reaches the selected temperature.
Cons:- S3102 valve is required and sold separately.
- Uses soft-touch buttons rather than a physical touchscreen.
- Two-outlet capacity is less suited to larger multi-fixture layouts.
Best for: Buyers pairing the S3102 valve with a two-outlet controller and seeking a matte black finish, app access, and voice-assistant compatibility.
Not ideal for: Those who need four outlets, expect a physical touchscreen, or want a controller that includes its own valve.
- Brand:Moen
- Model:TS3302BL
- Finish:Matte Black
- Outlets:2
- Display:5-inch LCD
- Controls:Soft-touch buttons
- Compatible valve:Moen S3102 thermostatic shower valve
- Connectivity:Alexa, Siri/HomeKit, Google Assistant, and U by Moen app
- Warranty:Limited lifetime warranty
Our verdict“I’d pick the TS3302BL for a two-outlet S3102 system when matte black styling and an explicitly named valve pairing are priorities.”
How We Picked
I ranked these products as parts of a smart shower system, not as standalone fixtures. A valve and a controller do different jobs: the thermostatic valve connects to the plumbing and manages outlets, while the digital controller sets shower preferences and, on compatible setups, enables app and voice functions. Treating either component as a complete system would make this comparison misleading.
My order reflects fit for a real buying decision. I gave priority to outlet capacity and the ability to match a component to a bathroom plan, then considered installation details such as connection size, standard 2×4 wall fit, cable length, and stated compatibility. I also looked at everyday controls—temperature adjustment, presets, warm-up pause, app, and voice support—because those features distinguish a smart shower from a basic digital valve.
I’ve kept drawbacks in view. Controllers and valves are sold separately in the supplied descriptions, and a controller’s smart features depend on the rest of the system; the four-outlet Terra Beige controller also calls out Wi-Fi and a compatible smart device for full functionality. The rankings are therefore use-case recommendations, not a claim that each item can work on its own. I use only the supplied product details and do not assume unlisted fittings, installation requirements, or compatibility.

Factors to Consider When Choosing Smart Shower Systems
For a smart shower, the most useful comparison starts with the complete component pairing. These Moen products divide into thermostatic valves and digital controllers, and most require a separately purchased counterpart. I’d settle the outlet plan and plumbing connections before choosing a finish or app feature.
Start by separating valves from controllers
The S3102 and S3104 are valves; the TS3302 and TS3304 models are controllers. A valve is the plumbing-side component that manages the shower outlets and temperature, while a controller provides the display and user adjustments. Buying a controller alone does not supply the valve, and buying a valve alone does not add the controller’s screen, presets, app access, or voice functions.
I’d make a parts list before ordering: valve model, controller model, number of outlets, and connection size. The S3102 specifies two outlets and 1/2-inch CC connections; the S3104 specifies four outlets and 3/4-inch CC connections. Those are not interchangeable assumptions. Match the equipment to the plumbing plan and verify the exact controller-to-valve compatibility in current product documentation.
Choose outlet capacity around the fixtures you plan to use
Two outlets suit a straightforward shower-and-hand-shower plan, while four outlets leave more room for a layout with additional fixtures. The S3102 and TS3302 controllers occupy the two-outlet category; the S3104 and TS3304TB are the four-outlet options in this group. A larger outlet count does not make a system a better choice if the bathroom has no use for the extra capacity.
Think through how fixtures will be used, not just how many can be installed. If the design calls for more than two outlets, compare the four-outlet components first. If it calls for two, the compact S3102 and a compatible two-outlet controller may be a more direct fit. Confirm how the chosen valve and controller work together before purchasing either component.
Check connection size and wall planning
The most obvious plumbing distinction is 1/2-inch versus 3/4-inch CC connections. The S3102 lists 1/2-inch connections, while the S3104 lists 3/4-inch connections. A plumber can help determine which configuration suits the supply lines and the shower’s design; do not choose solely by outlet count if the connections do not fit the plan.
Both valves are described as fitting a standard 2×4 wall, and each includes a 30-foot data cable. That can give the installation more flexibility when planning the controller’s location, but it does not replace a site-specific installation check. The S3102 also has a stated installation temperature range: the location must stay between freezing and 104°F. Confirm wall conditions and installation requirements before rough-in work.
Decide which smart controls you will use
The controllers in this roundup list voice-assistant and U by Moen app compatibility, alongside a 5-inch LCD and soft-touch buttons. That mix lets buyers use on-panel controls or connected features on compatible setups. The TS3304TB description specifically says full functionality depends on Wi-Fi and a compatible smart device, so connectivity should be part of planning if app or voice use is a priority.
Warm-up pause is another practical feature across the controller descriptions: flow can pause while the shower reaches the selected temperature. It can reduce water running during warm-up, though the feature relies on the correct controller-and-valve system. If a digital panel is mainly for local temperature and outlet control, connected features may matter less than a verified pairing and a comfortable control location.
Compare finish, interface, and warranty details
The TS3302BL and TS3302TB both offer two-outlet control, but the supplied descriptions distinguish them by finish and some product details. The black model names the S3102 as its required valve and lists a limited lifetime warranty; the Terra Beige model lists a five-year warranty on digital components and does not identify a specific compatible valve in the supplied text. I would confirm the current warranty and compatibility terms for the exact model before checkout.
Both controllers use soft-touch buttons with an LCD; the TS3302BL description explicitly says it is not a physical touchscreen. Consider where the panel will sit and whether button operation is what you want. Finish can help coordinate the room, but it should come after outlet capacity, valve pairing, connection size, and the requirements for connected features.
Budget for a system, not a single component
Because the valves and controllers are presented as separate pieces, I’d compare the full required combination rather than choosing one product page in isolation. A four-outlet plan calls for the appropriate valve and controller; a two-outlet plan also needs a compatible valve-controller pairing. The product descriptions do not establish that every listed component is bundled with the others.
Before purchase, ask the installer to review the exact model numbers, connections, controller compatibility, wall location, data cable route, and network needs. This step is especially useful when comparing the S3102 with the S3104, since connection size and outlet capacity both change. It can prevent a controller that looks right on paper from being paired with an unsuitable valve or plumbing layout.
Frequently Asked Questions
Are these products complete smart shower systems?
No. The S3102 and S3104 are digital thermostatic valves, while the TS3302 and TS3304 models are digital controllers. The supplied descriptions identify controllers or valves as sold separately, so I’d verify the full compatible combination and required fixtures before treating any single item as a complete system.
What is the difference between the S3102 and S3104 valves?
The S3102 supports two outlets and lists 1/2-inch CC inlet and outlet connections. The S3104 supports four outlets and lists 3/4-inch CC connections. Both are described as fitting a standard 2×4 wall and include a 30-foot data cable, but the plumbing connection size and planned outlet count should guide the choice.
Which controller should I choose for two outlets?
The TS3302BL and TS3302TB are the two-outlet controllers in this comparison. The TS3302BL specifically names the S3102 valve as required, while the supplied TS3302TB details say a thermostatic digital valve is needed without naming a model. I’d confirm the exact compatibility for the Terra Beige model before ordering and choose the finish and warranty terms that suit the project.
Do the Moen controllers support voice and app control?
The controller descriptions list compatibility with Amazon Alexa, Apple Siri/HomeKit, Google Assistant, and the U by Moen app. The TS3304TB description also says Wi-Fi and a compatible smart device are required for full functionality. I’d check network access and the requirements for the exact controller-and-valve setup if connected controls are part of the plan.
Can the warm-up pause feature help reduce water running before a shower?
The controller descriptions say the warm-up feature can pause water flow while the shower reaches the selected temperature. That can limit water running unused during the heating period, but the feature depends on a compatible Moen thermostatic valve and a properly configured system. Confirm the valve pairing and setup rather than assuming a controller alone provides the function.
Conclusion
My recommendation depends on the shower plan. For four outlets, start with the S3104 valve and pair it with the TS3304TB controller after confirming the 3/4-inch connections and system compatibility. For two outlets, the S3102 is the focused valve choice; pair it with a controller confirmed for that setup. Choose the TS3302BL when you want matte black styling and its stated S3102 pairing, or consider the TS3302TB for Terra Beige after checking its valve compatibility and warranty details.
Whichever route you choose, I would not order from outlet count or finish alone. These are separate system components, and the right decision hinges on the valve-controller match, plumbing connections, outlet plan, and whether you want app and voice features. Confirm those details with the installer before rough-in so the components support the shower you are actually building.
