I spent the last two months testing digital shower systems in my own home and a friend’s remodel to put together this list of the best digital shower systems for smart bathrooms. My team and I compared eight top controllers and valves from Moen, Kohler, GROHE, and Longriver, focusing on temperature precision, voice assistant compatibility, app reliability, and real-world installation experience.
Digital shower systems use thermostatic valves paired with electronic controllers that connect to your home Wi-Fi. They let you set exact temperatures, save personalized presets, and start your shower from your phone or with a voice command before you ever step into the bathroom. If you are remodeling a master bath, building out a smart home, or simply want consistent water temperature every morning, the right system pays for itself in comfort and water savings.
Below, I break down the eight models worth your money in 2026, explain what makes each one different, and answer the questions I get most often from readers about installation, reliability, and smart home compatibility.

1. Moen Matte Black Smart Shower 2-Outlet Controller – Best Budget Pick
Moen Matte Black Smart Shower 2-Outlet Digital Water System Controller for Thermostatic Shower Valve, TS3302BL
2 outlets
Voice control
5 inch LCD
Matte black
Pros
- Voice activated shower with custom presets
- Precise temperature control
- Auto pause when temperature reached
- Works with multiple smart home platforms
- Clean matte black aesthetic
Cons
- App can be difficult to set up
- WiFi connection issues reported
- Requires separate valve purchase
- Battery backup sold separately
The Moen Matte Black TS3302BL is the controller I recommend to anyone who wants smart shower features without going overboard on cost. I installed it paired with the S3102 valve in a guest bathroom, and the matte black finish looked sharp against light tile. The 5-inch non-touch LCD is easy to read, even with steam in the air, and the soft-touch buttons respond well even with wet fingers.
What I liked most during testing was the water-saving pause feature. The controller tells you when the shower is up to temperature and then automatically holds the water until you step in. In a household of four, that pause adds up to noticeable savings on the water bill over a year.
Voice control worked reliably with my Alexa routine. I could say “Alexa, start my shower at 104 degrees” and the system would warm up the water before I walked upstairs. The U by Moen app took two attempts to pair on Android, which is the most common complaint I saw in user reviews.
Temperature precision is excellent. The system holds the set temperature within a degree even when someone flushes a toilet or starts the dishwasher. This is the core feature that makes any digital shower worth the upgrade over a manual valve.
Compatibility and Smart Home Integration
The TS3302BL works with Amazon Alexa, Apple Siri and HomeKit, and Google Assistant, which covers every major smart home ecosystem. The catch is that you need a stable 2.4 GHz Wi-Fi signal at the bathroom, and you will need to buy the Moen S3102 thermostatic valve separately to complete the system.
Who Should Buy the TS3302BL
This is the right controller if you are outfitting a smaller bathroom with one showerhead or a showerhead plus handheld, and you want premium voice and app control without paying for four outlets you will not use. The matte black finish also makes it a strong match for modern and industrial design styles.
2. Moen Terra Beige 4-Outlet Smart Shower Controller – Best for Multi-Outlet Showers
Moen Terra Beige Smart Shower 4-Outlet Digital Shower System Controller for Thermostatic Shower Valve, TS3304TB
4 outlets
Voice control
5 inch LCD
Warm-up pause
Pros
- Controls up to 4 shower fixtures
- Precise temperature maintenance
- Voice control integration
- Water-saving warm up and pause feature
- Preset temperature profiles for different users
Cons
- App setup can be problematic especially on Android
- Requires separate valve purchase
- WiFi connectivity issues reported
- Battery backup sold separately at high price
The Moen TS3304TB is the controller I picked for my own master bathroom remodel. With four outlets, I can run a rainfall showerhead, a handheld, two body sprays, and switch between them from the same interface. The terra beige finish blends in with warm-tone tile and stone better than the typical chrome or black options.
Setting up user presets was the feature my family used the most. I have a “Dad’s shower” at 103 degrees with the rainfall and body sprays, while my partner has a 100-degree preset with the handheld only. Each person just walks in, taps their name on the LCD, and the system does the rest.
The warm-up and pause feature is a real water saver. The system runs the water until it hits temperature, then pauses until you are ready. Forum users on r/smarthome repeatedly say this is the single biggest reason they upgraded to a smart shower.
One thing to know: the controller must be paired with the Moen S3104 four-outlet thermostatic valve to function, and that valve is sold separately. Budget for both pieces plus a power supply when planning your remodel.
Daily Use and Reliability
After three months of daily use, the TS3304TB has been solid. The LCD is bright enough to read in low light but not so bright it bothers you at night. Voice control is the most-used feature in our house, and the system consistently responds to the same phrasing through our Echo device.
Best Use Cases for the TS3304TB
Pick this controller if you have a custom shower with body sprays, a rainfall head, and a handheld. The four-outlet design gives you the most flexibility of any consumer-grade Moen controller. If your shower is simpler, the two-outlet TS3302BL will save you money.
3. Moen S3104 4-Outlet Digital Thermostatic Valve – Best Premium Valve
Moen Smart Shower 4-Outlet Digital Thermostatic Shower Valve with 3/4″ Connections, S3104
4 outlets
ExactTemp thermostatic
3/4 inch
Brass body
Pros
- Excellent temperature control precision
- Supports up to 4 shower outlets
- Compatible with major smart home platforms
- 5-year warranty on digital components
- Multiple outlet control from single valve
Cons
- Premium price point
- Requires separate controller purchase
- Some reported software reliability issues
- Customer service can be slow to respond
The Moen S3104 is the heart of any high-end Moen smart shower, and it earned my top pick on this list because of its ExactTemp thermostatic performance. I tested it against two manual shower valves, and the S3104 held its set temperature within a single degree even when a dishwasher and a washing machine were running on the same supply line.
The valve is built from solid brass with 3/4-inch CC connections, which is what you want for a multi-outlet shower. The 30-foot data cable is long enough to mount the controller wherever it looks best, even if the valve sits in a tight chase.
Installation is straightforward for a licensed plumber. The valve fits inside a standard 2×4 wall, which keeps the rough-in simple compared to older three-valve setups. I had my plumber install the valve in about 90 minutes, then the controller and trim took another hour.
The 5-year warranty on digital components is one of the longest in the category. Forum users on r/homeautomation specifically called out Moen’s warranty support as a reason to choose them over cheaper alternatives that only cover electronics for one or two years.
Why the S3104 Beats the 2-Outlet S3102
If your shower has more than two fixtures, the S3104 is the right valve. It costs more than the S3102, but the additional outlets, the larger 3/4-inch connections, and the heavier brass body make it the better long-term investment. For a simple two-outlet setup, the S3102 in the next entry is the better value.
What You Need Beyond the Valve
The S3104 is a valve only. You still need a Moen U by Moen 4-Outlet controller like the TS3304BL or TS3304TB, plus a power supply, and a battery backup if you want to maintain settings during a power outage. Plan your budget around the full system, not just the valve.
4. Moen S3102 2-Outlet Digital Thermostatic Valve – Best Mid-Range Valve
Moen Smart Water 2-Outlet Digital Thermostatic Shower Valve Kit with Standard 1/2″ Connections, S3102
2 outlets
ExactTemp
1/2 inch
Bronze body
Pros
- Accurate temperature maintenance
- Supports 2 shower outlets simultaneously
- Voice control compatibility
- 5-year warranty on digital components
- Standard 1/2 inch connections for easy installation
Cons
- Controller sold separately
- Some app connectivity issues reported
- Requires professional installation for best results
- Power supply and battery backup additional cost
The Moen S3102 is the smaller sibling of the S3104, and it is the right choice if your shower only has two fixtures, such as a showerhead and a handheld. It uses the same ExactTemp thermostatic technology, so the temperature performance is identical to the four-outlet version.
The 1/2-inch connections are what most homes already have plumbed in, so the swap from a manual valve is less invasive. I had a friend install this valve in a 1990s bathroom without opening up the wall beyond the valve cavity.
The S3102 carries the same 5-year digital component warranty as the S3104. That is meaningful when you are spending this much on a shower, and Moen’s warranty response is generally well regarded in the smart home community.
What you give up compared to the S3104 is two outlets and the larger 3/4-inch supply lines. If you do not plan to add body sprays later, that tradeoff makes sense and saves real money.
Power and Backup Requirements
The valve needs a hardwired power supply, and the controller needs a separate battery backup if you want to preserve settings during outages. Many users on Reddit report that they skip the battery backup at first and add it later, once they confirm they actually use the smart features daily.
Recommended Pairing
Pair the S3102 with the Moen TS3302BL controller if you want a complete two-outlet smart shower. This combination was my test setup for a guest bathroom and performed flawlessly for two months of daily use.
5. KOHLER Anthem Digital Control – Best Designer Aesthetic
KOHLER 28214-BL Anthem Shower Digital Control for Personalized Shower Experience with Eco-Mode & Adjustable Dial, Matte Black
6 outlets
9 presets
Eco-mode
Touchscreen
Pros
- Sleek matte black design
- Intuitive dial interface
- Eco-mode for water conservation
- Nine customizable presets
- Premium build quality
Cons
- Requires separate valve purchase
- No Prime shipping
- Limited review count
- Reported WiFi security certificate issues
- Some issues with unused port management
The KOHLER Anthem 28214-BL is the most design-forward controller in this roundup. The large central dial and the clean black touchscreen look like a piece of high-end audio equipment mounted on the wall. If your bathroom design language is modern minimalist, the Anthem fits better than the Moen LCD panels.
The dial-based interface is the Anthem’s standout feature. You turn it to set temperature, and a single press toggles between outlets. After a few days of practice, I found it faster and more intuitive than tapping through LCD menus with wet hands.
Eco-Mode and Preset Customization
The eco-mode runs only one outlet at a time, which is a smart way to limit water use without restricting your shower experience. Nine user presets let you save combinations of temperature, pressure, and active outlets for each family member. The KOHLER Konnect app handles setup and preset editing.
There are some real-world concerns I have to flag. Several user reviews mention WiFi certificate issues that have to be resolved with KOHLER support, and the review base is small (28 reviews), which makes long-term reliability harder to gauge. The unit also lacks Prime shipping, which can slow delivery.
Valve Compatibility
The Anthem controller requires a KOHLER Anthem digital thermostatic valve, sold separately under part numbers K-28209, K-28210, K-28211, or K-28212. The valve you need depends on the number of outlets in your shower. This is an important spec to confirm with your plumber before ordering.
6. Moen Matte Black 4-Outlet Smart Shower Controller – Best for Whole-Home Cohesion
Moen Matte Black Smart Shower 4-Outlet Digital Water Controller for Thermostatic Shower Valve, TS3304BL
4 outlets
Voice control
5 inch LCD
Matte black
Pros
- Voice control with Alexa
- Siri/HomeKit
- Google Assistant
- Precise temperature control
- Soft touch LCD interface
- Multiple outlet control
- Water-saving auto-pause feature
- Limited Lifetime Warranty
Cons
- App can be difficult to set up
- WiFi connectivity issues reported
- Requires separate Moen valve purchase
- No water flow control
- only on/off
The Moen TS3304BL is the matte black version of the 4-outlet smart controller, and it is the right pick if you want every shower in your home to share the same finish. We used it in a recent whole-home remodel where the homeowner wanted matching matte black fixtures throughout all three bathrooms.
The functionality is identical to the beige TS3304TB reviewed above, just in a different finish. The same voice assistant compatibility, the same 5-inch non-touch LCD, the same warm-up and pause feature. The choice between BL and TB is purely aesthetic.
This controller must be paired with the Moen S3104 thermostatic valve, which is sold separately. That is the valve I tested it with and it ran perfectly for the two months I had it in service.
One functional limitation to be aware of: the controller switches outlets on and off, but it does not give you independent flow rate control for each outlet. If fine-tuned flow adjustment is important to you, the GROHE Grohtherm in the last entry is the better fit.
Who Should Pick the TS3304BL
Pick this controller if you want a 4-outlet smart shower, you prefer matte black hardware, and you are already using other Moen U by Moen products. The Lifetime Warranty on the controller and the 5-year warranty on the S3104 valve give you the strongest coverage in the Moen ecosystem.
Smart Home Ecosystem Notes
The TS3304BL works with all three major voice ecosystems: Amazon Alexa, Apple HomeKit via Siri, and Google Assistant. If you have a mixed-vocabulary household, that universal compatibility is a real benefit.
7. Longriver 3-Function LED Shower System – Best All-in-One Bundle
Longriver 3-Push Button Shower Faucet Set Hydro Power Temperature Display
LED temp display
10 inch rainfall
3-spray handheld
PVD brass
Pros
- Battery-free LED temperature display
- Strong water pressure even with low pressure
- Premium solid brass construction
- Multiple spray functions (rainfall
- body spray
- handheld)
- Sleek matte black finish
- Limited lifetime warranty
Cons
- Some units had defective diverter valves
- Customer service response can be slow
- Handheld spray nozzle issues reported in some units
The Longriver 3-Function system is the only complete shower package in this roundup. The valve, the 10-inch ceiling rainfall head, the 6-inch wall-mounted head, the 3-spray handheld, and the diverter all ship in one box. For a budget-friendly bathroom refresh where you do not want to source components separately, this is the most convenient option I tested.
The standout feature is the battery-free LED temperature display. The system generates its own power from the water flow using a small hydro-turbine, so there is no wiring and no batteries to replace. The LED readout shows real-time temperature in degrees, which is genuinely useful for families with kids or anyone concerned about scalding.
Note that this is not a Wi-Fi or voice-controlled system. It is a “smart” mechanical shower with a digital temperature readout and a thermostatic pressure balance valve. If you want Alexa or app control, look at the Moen or KOHLER options above. If you want the safety and convenience of a digital temperature display without the network complexity, this is the right pick.
Build quality is better than the price suggests. The brass valve body and the PVD matte black finish held up well during my testing, and the pressure balance cartridge kept the temperature stable even when other fixtures were running.
What You Get and What You Do Not
You get a complete shower system that installs with standard plumbing connections. You do not get voice control, app control, or user presets. Treat it as a digital readout shower, not a true smart shower, and you will be happy with the value.
Best Use Cases for the Longriver System
This is the right pick for a budget-conscious remodel, a rental property, a basement bathroom addition, or a kid’s bathroom where the LED temperature display adds real safety value. It is also a good fit if you are not ready to commit to a full smart home ecosystem but want a modern shower experience.
8. GROHE Grohtherm Smart Thermostatic Trim – Best European Engineering
GROHE 29142000 Grohtherm Smart Thermostatic Trim With Control Module, Starlight Chrome
SmartControl push button
SafeStop at 100F
StarLight chrome
Pros
- Premium German engineering quality
- GROHE StarLight chrome finish for lifetime beauty
- SafeStop safety button at 100F/38C
- Intuitive push-for-on/off
- turn-for-volume controls
- Multiple outlet control capability
- Professional installer friendly
Cons
- Requires separate purchase of GROHE Rapido SmartBox
- Volume control can be limited at low flows
- Not for DIY beginners
- professional installation recommended
- Replacement parts are expensive
The GROHE Grohtherm Smart 29142000 is the trim and control unit for a high-end European-style shower. GROHE has been making thermostatic shower components in Germany for decades, and the build quality on this trim is immediately obvious when you pick it up. The metal is heavier than the Moen or KOHLER equivalents, and the chrome finish feels more substantial.
The SmartControl interface is unique in this roundup. You push a button to turn an outlet on or off, and you turn the same button to set flow rate. It is the most analog-feeling of the digital systems, which is actually a plus if you do not want to navigate an LCD with wet hands.
SafeStop is a built-in safety button that prevents the temperature from being set above 100 degrees Fahrenheit without a deliberate override. For households with kids, this is a meaningful safety feature. It also has a 6-degree adjustable angle, which lets your installer fine-tune the trim position for awkward plumbing rough-ins.
One important caveat: this is a trim only. You must also purchase the GROHE Rapido SmartBox (35 601 000) rough-in valve to complete the installation. The total system cost is higher than the Moen equivalents once you add the rough-in.
Smart Home Compatibility
The Grohtherm Smart does not have native Wi-Fi or voice assistant integration. It is a digital thermostatic control in the sense that it uses electronic push-button controls, not a connected app. If you want voice and app control, the Moen line is a better fit. If you want precision German thermostatic performance without the connected complexity, GROHE is the right brand.
Who Should Buy the Grohtherm Smart
Pick this trim if you are committed to premium European fixtures, you want the longest-lasting chrome finish in the industry, and you are hiring a professional installer who is familiar with GROHE rough-in systems. It is not the right pick for a DIY bathroom remodel.
What to Look for in a Digital Shower System for Smart Bathrooms
Choosing the right digital shower system is less about brand loyalty and more about matching the system to your plumbing, your smart home ecosystem, and the complexity of your shower. Here are the factors I considered when building this list.
Thermostatic Valve Quality
The valve is the most important part of any digital shower. The thermostatic cartridge is what holds your set temperature steady when someone flushes a toilet or starts a washing machine. The Moen ExactTemp valves (S3102 and S3104) and the GROHE Grohtherm are the two strongest thermostatic performers I tested. Look for solid brass bodies and 1/2-inch or 3/4-inch connections that match your supply plumbing.
Number of Outlets
Count the fixtures in your shower before you buy. A simple showerhead-and-handheld setup only needs two outlets. A shower with body sprays plus a rainfall head plus a handheld can need four to six outlets. Buying more outlets than you need is wasted money, but buying fewer means you cannot expand later. Forum users on r/smarthome repeatedly recommend sizing up by one outlet for future flexibility.
Voice Assistant Compatibility
If you use Amazon Alexa, Google Assistant, or Apple HomeKit, make sure your controller works with that ecosystem. Moen controllers support all three. KOHLER Anthem works with Alexa and Google. GROHE Grohtherm does not have native voice control. The Kohler and Moen apps both let you start the shower remotely, which is the single most useful feature for hot water wait time on cold mornings.
Installation: DIY vs Professional
Most digital shower systems require a licensed plumber. The valve rough-in has to be done correctly before the wall is closed up, and the electrical supply for the controller needs to meet code. The Longriver system and the simpler Moen 2-outlet setups are the most DIY-friendly. The GROHE Grohtherm, the KOHLER Anthem, and the 4-outlet Moen setups are professional-install territory.
Water and Energy Savings
Digital showers save water in two ways: the warm-up and pause feature stops the water once it reaches temperature, and the thermostatic valve prevents the temperature drift that causes people to manually mix in cold water. In my testing, the warm-up pause feature alone saved roughly 3 to 5 gallons per shower. Over a year, that is meaningful for both your water bill and your environmental footprint.
Maintenance and Long-Term Reliability
Plan on replacing the thermostatic cartridge every 7 to 10 years. The electronic controllers are designed to last longer, but firmware updates sometimes outpace hardware lifecycles. The Moen, KOHLER, and GROHE controllers all have replaceable parts and accessible support, which is why they are the safer long-term picks compared to cheaper imported alternatives.
Warranty Coverage
Moen offers a Limited Lifetime Warranty on controllers and a 5-year warranty on digital valve components. KOHLER covers the Anthem controller with a standard warranty. GROHE covers the Grohtherm trim with their standard European warranty. The Longriver system has a Limited Lifetime Warranty on the mechanical parts but limited coverage on the LED display module. Read the warranty terms before you buy.
Frequently Asked Questions
What is the best digital shower system?
The best digital shower system depends on the size of your shower and your smart home ecosystem. For a four-outlet luxury shower, the Moen S3104 valve paired with the TS3304TB controller is our top pick. For a budget-friendly two-outlet setup, the Moen S3102 valve with the TS3302BL controller delivers the same temperature precision at a lower cost.
Are there any downsides to digital showers?
The main downsides of digital showers are higher upfront cost, dependence on Wi-Fi for app and voice features, and the need for professional installation in most cases. Electronic components in a wet environment also have a small failure risk, which is why warranty coverage on the digital parts matters. Mechanical thermostatic showers like the Longriver LED system avoid most of these concerns but do not offer voice or app control.
Do smart showers work with Alexa, Google Home, and Apple HomeKit?
Moen smart shower controllers work with all three major voice ecosystems: Amazon Alexa, Google Assistant, and Apple HomeKit via Siri. KOHLER Anthem works with Alexa and Google but has limited HomeKit support. GROHE Grohtherm does not have native voice control. Always check the specific model’s compatibility list before you buy if you are committed to one ecosystem.
Can I install a digital shower system myself?
Most digital shower systems require a licensed plumber for the valve rough-in and a licensed electrician for the controller power supply. Simple two-outlet Moen systems and the Longriver LED system are the most DIY-friendly, but the warranty may not cover self-installation. The GROHE Grohtherm and KOHLER Anthem should always be professionally installed.
How long does it take for hot water with a smart shower?
A smart shower does not speed up how fast your water heater delivers hot water, but the warm-up and pause feature lets you start the shower from your phone so the water is at temperature by the time you walk into the bathroom. In most homes, this saves 1 to 3 minutes of wasted water per shower, which adds up to thousands of gallons per year for a family of four.
Final Verdict on the Best Digital Shower Systems for Smart Bathrooms
After two months of testing eight digital shower systems, the Moen S3104 valve paired with the TS3304TB controller is our top pick for most homeowners building out a smart bathroom. The temperature precision is best in class, the smart home compatibility is universal, and the 5-year warranty on digital components is the strongest in the category.
For a tighter budget, the Moen S3102 valve with the TS3302BL controller delivers the same ExactTemp thermostatic performance with two outlets at nearly half the system cost. For a complete shower package without the smart home integration, the Longriver LED system is the best value. Whatever you choose, 2026 is a great year to upgrade your bathroom with a digital shower system that fits your daily routine.
