Shoppers searching for app-controlled shower systems will find three very different approaches here: the Moen TS3302BL pairs a digital controller with app and voice-assistant support, the KOHLER Anthem prioritizes multi-outlet control and presets, and the hai handheld showerhead adds app-based water tracking to a simpler shower setup. My leading choice for a connected, multi-outlet shower is Moen, while KOHLER makes more sense for a system with several outlets to manage. hai is the accessible pick for tracking water use without replacing an entire digital valve system. The main tradeoff is scope: hai is a smart showerhead, whereas Moen and KOHLER are controllers that require compatible valves sold separately.

Key Takeaways
- Moen TS3302BL is the clearest fit for buyers who want app and voice control, but it requires a separate S3102 valve and manages only two outlets.
- KOHLER Anthem can manage up to six outlets and offers nine presets, making it the strongest choice for a more elaborate multi-outlet installation.
- hai Smart Bluetooth Handheld tracks water use and provides LED alerts without a digital thermostatic valve, but it does not control multiple built-in outlets.
- The hai connects through water-powered Bluetooth; Moen lists broader app and voice-assistant compatibility, while the Anthem uses its touchscreen and dial.
- Before choosing either digital controller, check valve compatibility and installation scope: both Moen and KOHLER require a separately sold valve.

More Details on Our Top Picks
Moen Matte Black Smart Shower 2-Outlet Digital Controller, TS3302BL
The Moen TS3302BL is my strongest all-around choice for buyers who want connected controls as part of a planned digital shower installation. It supports the U by Moen app along with Alexa, Siri/HomeKit, and Google Assistant, so users can choose between a phone, voice assistant, or the controller itself. Its two-outlet capacity covers a straightforward combination such as a showerhead and handheld, but it is not built for the larger multi-outlet layouts that the KOHLER Anthem can manage.
A useful day-to-day distinction is Moen’s ability to pause water while the shower heats. That gives the user a way to avoid letting water run continuously before stepping in, rather than limiting smart features to remote settings or presets. The five-inch LCD displays information, but its controls are soft-touch buttons rather than a touchscreen. Buyers who expect tap-based interaction may prefer the Anthem’s touchscreen and dial, especially if they want to manage more outlets from a central control.
The main qualification is installation: this controller requires a separate Moen S3102 thermostatic valve. I would treat it as part of a compatible Moen system, not a standalone upgrade to any existing shower. Compared with hai, it offers much more control over temperature and outlets, but the hai is a simpler fit for someone who only wants water tracking and an adjustable handheld. Moen is the more capable connected system here, provided the buyer accepts its valve requirement and two-outlet limit.
Pros:- Supports the U by Moen app and several major voice-assistant platforms
- Controls temperature and two shower outlets
- Can pause water flow while the shower heats
- Provides presets through a dedicated LCD control
Cons:- Requires a separately sold Moen S3102 thermostatic shower valve
- Manages only two outlets and has a non-touch LCD
Best for: Buyers planning a Moen digital shower who want app access, voice-assistant support, presets, and control of two outlets.
Not ideal for: Anyone seeking a standalone controller, a touchscreen interface, or management of more than two outlets.
- Brand:Moen
- Model:TS3302BL
- Finish:Matte black
- Outlet capacity:2 outlets
- Display:5-inch non-touch LCD
- Compatibility:Amazon Alexa, Apple Siri/HomeKit, Google Assistant, U by Moen app
- Required valve:Moen S3102 thermostatic shower valve, sold separately
- Warranty:Limited lifetime warranty
Our verdict“I recommend the Moen for buyers who want the broadest app and voice-control options in this lineup and are ready to install its matching valve.”
KOHLER Anthem Digital Shower Control, Matte Black
Where Moen targets a connected two-outlet setup, the KOHLER Anthem is the better match for a shower with several water outlets to coordinate. It supports up to six outlets, and its touchscreen and dial let users set temperature and flow and move among nine customizable presets. That capacity gives it a clear role in this lineup: it is the pick for buyers who care more about managing a complex shower layout than about listed app or voice-assistant access.
The Anthem’s optional eco mode uses one outlet at a time, a more specific approach to limiting simultaneous water use than the basic control functions described for Moen. Nine presets also give household members a way to save preferred settings instead of repeatedly adjusting the shower. Those features make the KOHLER more flexible than the hai, which tracks use and displays alerts but does not operate a multi-outlet digital system. Still, the supplied details do not list smartphone or voice control, so I would not choose it on the assumption that the touchscreen makes it app-connected.
Like Moen, the Anthem is not a complete, ready-to-fit control system by itself: it requires a separately sold Anthem digital thermostatic valve. Its listed construction is plastic, and buyers should verify that the required valve and the rest of their planned system suit their installation before selecting the control. Compared with Moen, KOHLER offers far more outlet capacity but lacks the stated app and voice platform support. It is the more compelling option for a multi-outlet layout, not for someone whose main goal is phone-based operation.
Pros:- Manages up to six outlets
- Offers nine user-definable presets
- Combines a touchscreen with a physical dial
- Optional eco mode runs one outlet at a time
Cons:- Requires a separately sold Anthem digital thermostatic valve
- No app or voice-assistant compatibility is listed in the supplied details
Best for: Homeowners designing a multi-outlet shower who want centralized temperature, flow, and preset control for as many as six outlets.
Not ideal for: Buyers who specifically require smartphone or voice-assistant control, or who want a controller that works without a matching valve.
- Manufacturer:KOHLER
- Model:28214-BL
- Color:Matte black
- Material:Plastic
- Outlet capacity:Up to six outlets
- Presets:Nine user-definable presets
- Controls:Touchscreen and dial
- Required component:Anthem digital thermostatic valve, sold separately
Our verdict“I would choose the Anthem over Moen for a multi-outlet shower, but not if direct app or voice control is the deciding feature.”
hai Smart Bluetooth Handheld Showerhead, Persimmon, 1.8 GPM
The hai Smart Bluetooth Handheld takes a different route from the two digital controllers. Rather than managing thermostatic valves and several outlets, it connects to the hai app through water-powered Bluetooth to track water use and support customizable LED temperature and usage alerts. That makes it the most approachable choice for buyers who want connected feedback on an existing shower, without planning a full digital-control installation.
Its practical advantage is a relatively simple fit: it installs on a standard ½-inch NPT shower arm without special tools and can be used handheld or wall-mounted. Adjustable spray settings span a high-pressure stream to a fine mist, while the flexible hose is described as easy to clean. Moen and KOHLER offer more direct control over system temperature, flow, or multiple outlets; hai instead focuses on monitoring, alerts, and the handheld shower experience. Buyers should not confuse app-based tracking with app-based control of a whole shower system.
The boundaries are clear. This model is not designed for rain-shower or rail-shower setups, and app tracking requires a compatible device. It also cannot serve as a replacement for the Moen or KOHLER controllers when the goal is to run multiple outlets or set a complete digital shower. For someone who wants to understand water use and get visual alerts while keeping a standard shower arrangement, hai is the most accessible pick. For anyone seeking smart temperature control or several independently managed outlets, the other two products are better aligned.
Pros:- Tracks water use through the companion app
- Provides customizable LED temperature and usage alerts
- Adjustable spray settings support different shower preferences
- Installs on a standard shower arm without special tools
Cons:- Not designed for rain-shower or rail-shower setups
- App connectivity and tracking require a compatible device
- Does not control a multi-outlet digital shower valve
Best for: Buyers with a standard shower arm who want app-linked water-use tracking, customizable LED alerts, and a handheld showerhead.
Not ideal for: Shoppers building a rain or rail shower, or anyone who needs app-controlled temperature and multi-outlet valve operation.
- Brand:hai
- Model:HSBTLO6
- Flow rate:1.8 GPM
- Material:Stainless steel
- Color:Persimmon
- Connectivity:Water-powered Bluetooth
- Spray settings:Adjustable stream to fine mist
- Installation:Standard ½-inch NPT wall-mounted shower arms
- Warranty:2 years
Our verdict“I recommend hai for straightforward app-linked water tracking, not as a substitute for the system-level controls offered by Moen or KOHLER.”
How We Picked
I ranked these products by how well their smart features answer different shower-control needs, rather than treating every connected device as the same kind of system. Control capability came first: I compared app access, temperature and flow adjustment, outlet management, and water-use feedback. That distinction matters because the hai is a connected handheld showerhead, while the Moen and KOHLER are digital controllers designed to operate compatible valve systems.
I also weighed installation requirements and system fit. A controller that promises multiple outlets is useful only if a buyer is prepared to add its required thermostatic valve and build around the matching platform. The Moen earns the top position for broad connected control and practical heat-up pausing, while KOHLER ranks close behind for its higher outlet capacity and extensive presets. hai ranks as the best value-oriented entry into connected shower features because it adds tracking and alerts to a standard shower arm, though it cannot match the controllers’ system-level functions.
Finally, I looked at the tradeoffs a buyer will notice after comparing the feature lists: outlet limits, control interfaces, compatibility, and how much of the existing shower may need replacement. I have not treated these products as interchangeable or assumed hands-on performance. Each recommendation suits a distinct installation, and the ranking reflects how much useful connected control each provides for its intended buyer.

Factors to Consider When Choosing Appcontrolled Shower Systems
These three picks use the word smart in different ways. I would start by identifying whether the goal is water-use feedback, connected temperature and outlet control, or a full multi-outlet digital shower. That choice will quickly narrow the lineup.
Decide Whether You Need a Showerhead or a Digital Controller
The hai is a smart handheld showerhead: it tracks use and provides LED alerts through a connected app, but it does not replace a digital valve controller. Moen and KOHLER are control components for a broader shower system. They adjust temperature and flow, but each needs its own separately sold thermostatic valve. I would choose hai when the existing shower is basically right and the missing feature is usage feedback. If the aim is to create a coordinated digital shower, compare the two controller systems instead.
Match Outlet Capacity to the Layout
Count the outlets you intend to operate before choosing a controller. Moen supports two outlets, which suits a simpler showerhead-and-handheld arrangement. The KOHLER Anthem supports up to six, making it the clearer candidate for a more involved layout. Extra capacity is useful only if the shower actually needs it, so I would not select a larger controller just because its maximum is higher. The hai does not manage a set of separate outlets at all.
Check App and Voice Features Carefully
For explicit app and voice-assistant compatibility, Moen has the strongest listed feature set: its controller works with the U by Moen app, Alexa, Siri/HomeKit, and Google Assistant. hai connects to its app using water-powered Bluetooth, with water-use tracking and alerts as its focus. The supplied Anthem details describe touchscreen and dial operation but do not specify app or voice support. I would verify the control method that matters to you instead of assuming every digital controller offers the same connected functions.
Account for the Valve and Installation
Both digital controllers have a system requirement that can shape the project: Moen needs the S3102 thermostatic valve, and KOHLER needs an Anthem digital thermostatic valve. These are not standalone replacements for a basic shower control. Check the valve, plumbing, and product-platform fit with a qualified installer before ordering. By contrast, hai is designed for a standard ½-inch NPT shower arm and does not call for a separate digital valve, although its compatible-device requirement still applies to app features.
Choose the Interface You Will Prefer
The Moen has a five-inch non-touch LCD with soft-touch buttons, while KOHLER combines a touchscreen with a dial. Some buyers may prefer a physical control rather than taps on a screen; others may value the Anthem’s touchscreen and capacity for more outlets. hai puts customizable LED alerts on the showerhead and uses its companion app for tracking. I would weigh these interfaces alongside the location and accessibility of the control, not just the feature list.
Separate Water Feedback from Water Control
Water-use tracking and water-saving control are not the same function. hai provides usage tracking and customizable alerts, which can help users monitor their shower habits. KOHLER’s optional eco mode instead uses one outlet at a time. Moen can pause flow while water heats, which addresses a different moment in the shower routine. Choose the feature that matches the intended outcome; no single product here combines all of these functions.
Frequently Asked Questions
Which product is the most directly app-connected?
The Moen TS3302BL lists support for the U by Moen app and several voice assistants, giving it the broadest stated connected-control options. The hai handheld also connects to an app, but its focus is water-use tracking and alerts rather than operating a digital valve system. KOHLER’s supplied feature details specify touchscreen and dial controls, not app access.
Can I install the Moen or KOHLER controller without buying a valve?
No. The Moen requires a separate S3102 thermostatic shower valve, and the KOHLER Anthem requires a separately sold Anthem digital thermostatic valve. Those parts are central to how each controller operates, so check compatibility and installation needs before treating either control as an upgrade for an existing shower.
Which option works with the most shower outlets?
The KOHLER Anthem has the highest listed capacity, supporting up to six outlets. Moen operates two outlets, which is a better fit for a simpler configuration. hai is a handheld showerhead rather than an outlet-management controller, so it is not a direct competitor on outlet count.
Does the hai showerhead control water temperature through the app?
The provided details describe the hai app as a way to track water use and customize temperature and usage alerts. They do not describe app-based temperature adjustment like the Moen and KOHLER digital controls. I would choose hai for feedback and alerts, not for remote adjustment of a complete shower’s temperature and outlets.
Which product should I choose for a basic existing shower?
If the shower uses a standard ½-inch NPT shower arm and you want app-linked tracking without adding a digital valve system, the hai handheld is the closest fit. Moen and KOHLER suit buyers planning a compatible digital shower installation and willing to add the required valve. Check the hai’s stated limits too: it is not designed for rain-shower or rail-shower setups.
Conclusion
My recommendation depends on what “app-controlled” means for your shower. Choose the Moen TS3302BL if you want app and voice-assistant access, two-outlet control, presets, and a pause function while the water heats—and if you are prepared to install the required Moen valve. Pick the KOHLER Anthem for a more complex shower with up to six outlets and a preference for touchscreen-and-dial control, rather than a listed app connection. Select the hai Smart Bluetooth Handheld if you want water-use tracking and LED alerts on a standard shower arm without rebuilding the shower around a digital valve. I would make valve compatibility and the type of smart control the deciding checks before choosing between them.
