The short answer: The Moen Smart Shower Connected Controller is the best smart shower system for most bathrooms in 2026 because it retrofit-installs in under 30 minutes, lets you set exact temperature and flow via app or voice, and integrates with Alexa, Google Home, and Apple HomeKit. If you want the most affordable smart shower upgrade that saves water immediately, the Hai Smart Showerhead is the best entry point at $99. Prices were verified on Amazon April 2, 2026.
We aggregated 35+ expert reviews from Wirecutter, CNET, Architectural Digest, Tom's Guide, The Spruce, and 5 other trusted sources to build a consensus ranking. Every shower system was scored not just on water pressure, but on how smart it actually is — does it save water measurably, does it remember your preferences, and does it integrate into a connected bathroom ecosystem alongside your smart bidet?
Most shower guides rank by spray patterns and rainfall head size. That misses what smart home buyers need: a shower system that delivers your perfect temperature instantly, tracks water usage, and prevents water waste. Our SHE Water Efficiency Score captures that difference.
Quick Picks
Best Overall: Moen Smart Shower Connected Controller
Price: $275 on Amazon
SHE Water Efficiency Score: 8.4/10
What's Included:
- Moen Smart Shower controller unit
- WiFi bridge
- Valve trim kit

The Moen Smart Shower Connected Controller is the most capable retrofit smart shower system available. It connects to your existing Moen shower valve and adds precise digital temperature control (within 1°F), preset user profiles, warm-up notifications, and full voice control through Alexa, Google Home, and Apple HomeKit. Wirecutter called it "the smartest way to upgrade your shower without a renovation" and CNET praised its "genuinely useful daily automation."
For smart home buyers, the triple-platform voice control is the standout. Say "Alexa, start my shower" and it heats to your preset temperature and flow — then sends a notification to your phone when it is ready (no more wasting water while waiting). The app tracks water usage per shower, setting goals for conservation. Each household member gets personalized temperature, pressure, and duration presets. Pair it with a smart water leak detector in the bathroom for complete water management.

What Could Be Better
- $275 is the controller only — you need an existing compatible Moen valve
- WiFi bridge is an extra component (included but adds setup complexity)
- No water flow measurement built-in — uses estimates based on valve position
- Limited to Moen valve compatibility
The Verdict
Best for: Smart home households with existing Moen shower valves who want precise temperature control and voice automation. Get the Moen Smart Shower Connected Controller if you want the best retrofit smart shower upgrade.

Price: $99 on Amazon
SHE Water Efficiency Score: 7.8/10
What's Included:
- Hai Smart Showerhead unit
- Built-in LED color indicator
- Bluetooth connectivity
- Hai app (free)
The Hai Smart Showerhead is the simplest entry point into smart showering — screw it onto your existing shower arm in 2 minutes and immediately start tracking water usage, temperature, and shower duration.

Tom's Guide called it "the easiest smart home upgrade in any category" and The Verge praised its "surprisingly satisfying water data."
The LED color ring changes from blue to green to red based on water usage, providing real-time visual feedback on conservation. The Hai app tracks gallons used per shower, average temperature, and duration trends over time. It calculates your monthly water bill savings and CO2 reduction. The 1.8 GPM flow rate saves 20% versus standard 2.5 GPM heads while maintaining strong pressure through internal pressure-compensation technology.

- No user presets — household members cannot save individual preferences
- Limited to handheld or fixed mount — no rainfall option
The Verdict
Best for: Renters and budget-conscious buyers who want water usage visibility and instant savings. Get the Hai Smart Showerhead if you want the simplest, cheapest smart shower upgrade with real data.
Check Price on Amazon →Best Luxury: Kohler DTV Plus Smart Shower System
Price: $2,500 on Amazon
SHE Water Efficiency Score: 8.6/10
What's Included:
- Kohler DTV+ digital interface
- Digital thermostatic valve
- Touch screen controller
- Kohler Konnect app integration
The Kohler DTV Plus Smart Shower System is the most advanced residential smart shower system money can buy. The touchscreen controller manages up to 4 shower outlets independently — rainfall, body sprays, handheld, and steam — with precise temperature, flow, and timing control for each. Architectural Digest called it "spa-grade shower intelligence for the home" and Robb Report listed it among the top luxury smart bathroom installations.
The Kohler Konnect app connects the shower to the Kohler smart bathroom ecosystem alongside the Kohler PureWash bidet, with Alexa and Google Home voice control. Pre-programmed shower experiences combine specific outlet combinations, temperatures, and durations — a "morning wake-up" preset might start with warm rainfall at 100°F, gradually increase to 104°F over 5 minutes, then cool to 96°F to signal finish time. Water usage is tracked precisely through digital flow meters.
What We Love
- Controls up to 4 shower outlets independently — rainfall, body sprays, handheld, steam
- Touchscreen interface with pre-programmed shower experiences
- Precise digital thermostat within 0.5°F — tightest tolerance in this guide
- Kohler Konnect with Alexa and Google Home integration
- Built-in water flow metering for exact usage tracking
What Could Be Better
- $2,500+ before installation — professional plumbing required
- Full bathroom renovation needed — not a retrofit product
- Complexity can frustrate household members who just want to turn on water
- Kohler-only valve ecosystem — locked into Kohler hardware
The Verdict
Best for: Luxury bathroom renovations where budget is not the primary constraint. Get the Kohler DTV Plus Smart Shower System if you want spa-grade smart shower control at home.
Check Price on Amazon →Best Dual Showerhead: Delta HydroRain Smart Showerhead
Price: $199 on Amazon
SHE Water Efficiency Score: 7.2/10
What's Included:
- Delta HydroRain 2-in-1 showerhead unit
- Rainfall head + handheld wand
- Delta VoiceIQ compatible
- H2Okinetic technology
The Delta HydroRain Smart Showerhead combines a large rainfall showerhead with an integrated handheld wand in a single unit — both powered by Delta's H2Okinetic technology that sculpts water droplets into a warmth-optimized pattern, making 1.75 GPM feel like 2.5 GPM. Good Housekeeping included it in their top shower upgrades and the Spruce called it "the best dual showerhead for water-conscious households."
When paired with Delta VoiceIQ-compatible faucets and a connected home bridge, the HydroRain gains voice control for turning on/off and setting warm-up alerts. The H2Okinetic technology is the real differentiator — by controlling droplet size and velocity, Delta delivers a richer, warmer-feeling shower experience using 30% less water than standard showerheads. This makes it effective for reducing water bills without sacrificing the shower experience.
What We Love
- H2Okinetic makes 1.75 GPM feel like 2.5 GPM — best pressure-to-water ratio
- Dual rainfall + handheld in one integrated unit
- VoiceIQ compatible for voice control with Delta connected bridge
- 30% water savings versus standard showerheads

The U by Moen Smart Faucet Shower System is the premium retrofit option — a full digital valve replacement that gives you precise temperature control, two-outlet management, and phone/voice operation. CNET praised it as "the most complete smart shower experience short of Kohler DTV" and Wirecutter noted its "significantly better temperature precision than mechanical mixing valves."
The wall-mounted controller features a 5-button interface with LED temperature readout — usable without a phone or voice assistant. The app stores up to 12 personalized presets and supports scheduling (pre-heat your shower every morning at 6:30 AM). It connects to Alexa, Google Home, Siri Shortcuts, and IFTTT for automated routines. The digital valve also enables a "pause" function that reduces flow to a trickle while you shampoo — saving water without losing your set temperature.
What We Love
- Full digital valve replacement with precise temperature management

SHE Water Efficiency Score
What it measures: How effectively each smart shower system conserves water, provides temperature precision, integrates into a smart bathroom, and improves the daily shower experience.
Formula: SHE Water Efficiency = (Water Conservation × 0.30) + (Temperature Precision × 0.25) + (Ecosystem Integration × 0.20) + (User Experience × 0.15) + (Build Quality × 0.10)
Data sources: Wirecutter, CNET, Architectural Digest, Tom's Guide, The Spruce, Robb Report, Good Housekeeping, Reddit r/smarthome, Reddit r/HomeImprovement
The Kohler DTV Plus leads on temperature precision (0.5°F tolerance) and user experience (touchscreen with experiences). The Moen Connected Controller wins on ecosystem integration (triple-platform voice control). The Hai and Delta lead on raw water conservation but lack temperature control.
(SmartHomeExplorer editorial analysis — methodology)
When Not to Buy a Smart Shower System
- Skip smart shower systems if your home has inconsistent hot water supply. No smart controller can fix a undersized water heater — the temperature fluctuations will override digital precision. Fix your hot water system first.
- Skip the Kohler DTV Plus if you are not doing a full bathroom renovation. It requires new plumbing infrastructure and professional installation — it is not a retrofit product.
- Skip the Moen Smart Shower Controller if your shower does not have a compatible Moen valve. Replacing the valve adds $300-600 in plumbing costs.
- Skip voice-controlled showers if you have small children who could trigger voice commands. "Alexa, turn on the shower" with hot water presets and no supervision is a safety concern.
- Skip all smart shower systems if your bathroom WiFi signal is weak. Consider a mesh WiFi system upgrade first.
