The Ultimate Guide to Smart Toilets in 2026: Luxury, Hygiene, and Home Automation

Introduction

The smart toilet has evolved from a niche luxury item into a cornerstone of the modern smart home. In 2026, these intelligent fixtures offer more than just heated seats and bidet functions—they integrate seamlessly with your home automation ecosystem, provide health monitoring, and deliver unprecedented water efficiency. As a smart home technology reviewer, I’ve tested dozens of models across various price points, from budget-friendly retrofit seats to fully integrated luxury units. The challenge for most consumers is navigating the sea of features—UV sterilization, self-cleaning nozzles, motion-activated lids, and voice control—while balancing cost and installation complexity. In this comprehensive guide, I’ll break down the top three smart toilets of 2026, compare key features, and help you decide which model fits your home and lifestyle. Whether you’re a tech enthusiast looking to upgrade your bathroom or a homeowner seeking improved hygiene, this review will equip you with the knowledge to make an informed purchase.

Top 3 Product Recommendations

1. TOTO Neorest NX2 (2026 Edition) – The Premium Powerhouse

Price: $5,200 – $5,800 (estimated 2026 retail) Best for: Luxury homeowners seeking the ultimate in comfort and automation

The TOTO Neorest NX2 remains the gold standard in smart toilets, and the 2026 edition refines an already exceptional product. This integrated toilet-bidet combination features TOTO’s proprietary Tornado Flush system, which uses dual-nozzle technology to create a powerful centrifugal flush that cleans the bowl with minimal water—just 1.0 gallon per flush (GPF). The heated seat is ergonomically contoured and includes a “Prewarm” function that activates 30 minutes before your typical usage time, learned via the built-in AI. The bidet offers adjustable water temperature, pressure, and position, with a oscillating spray mode that’s surprisingly soothing.

On the smart home front, the NX2 now supports Matter protocol, allowing native integration with Apple HomeKit, Amazon Alexa, and Google Home. You can trigger the flush, adjust seat temperature, or activate the deodorizer with voice commands. The lid automatically opens when it detects your approach (within 24 inches) and closes after 90 seconds of inactivity. The self-cleaning nozzle uses UV light and electrolyzed water to sanitize after every use, while the built-in air purifier eliminates odors within 10 seconds. The 2026 model adds a “Health Monitor” feature that analyzes urine color and weight patterns, syncing data to the TOTO Wellness app—though this requires a subscription ($4.99/month after the first year).

Pros:

• Exceptional build quality and ceramic glaze (resists staining)
• Full Matter protocol support for smart home integration
• Health monitoring features are genuinely useful for tracking hydration
• Whisper-quiet operation (under 30 dB during flush)

Cons:

• Requires a dedicated 110V outlet (GFCI protected)
• No heated air dryer (must use bidet then pat dry)
• Subscription cost for advanced health features

Verdict: The Neorest NX2 is the smart toilet equivalent of a luxury sedan—it does everything well, but you pay a premium for the privilege. Ideal for homeowners who want the best and are willing to invest in their bathroom experience.

2. Kohler PureWash E930 – The Mid-Range Champion

Price: $1,200 – $1,500 (estimated 2026 retail) Best for: Tech-savvy homeowners upgrading an existing toilet

If you’re not ready to replace your entire toilet, the Kohler PureWash E930 bidet seat offers most of the features of an integrated unit at a fraction of the cost. Designed to fit most standard two-piece toilets (elongated or round), this retrofit seat includes a heated seat, adjustable bidet with front and rear wash, and a warm air dryer. The E930 uses a sleek, low-profile design that doesn’t look like an afterthought—the control panel is a wireless remote that mounts on the wall or sits on a countertop.

Smart home integration is where the E930 shines. It connects via Wi-Fi to the Kohler Konnect app, which allows you to set user profiles (up to four), adjust water temperature and pressure, and schedule seat heating times. The E930 also works with Alexa and Google Assistant for voice control, though commands are limited to basic functions like “turn on bidet” or “set seat temperature to warm.” The 2026 model adds “Auto-Flush” detection—a sensor that triggers a flush when the user stands up, but this only works if your toilet has a compatible flush valve (most modern Kohler toilets do). The self-cleaning wand retracts after each use and is UV-sanitized, while the nozzle position adjusts automatically based on the user’s weight distribution.

Pros:

• Easy DIY installation (takes about 45 minutes)
• Excellent water pressure customization (five settings)
• Warm air dryer is genuinely effective (dries in under 60 seconds)
• No subscription fees for app features

Cons:

• Does not include toilet bowl (must have compatible toilet)
• Auto-flush feature is finicky with older toilets
• Remote control feels plasticky compared to the seat

Verdict: The PureWash E930 is the smartest choice for most homeowners. It delivers 80% of the luxury experience at 25% of the cost. The only catch is that you need a decent existing toilet—if yours is over 15 years old, consider replacing it first.

3. Bio Bidet Ultimate 770 – The Budget-Friendly Powerhouse

Price: $499 – $599 (estimated 2026 retail) Best for: Renters or budget-conscious buyers who want essential smart features

Bio Bidet has carved a niche in the affordable smart toilet market, and the Ultimate 770 is their best-selling model for good reason. This bidet seat offers heated seating, a stainless steel self-cleaning nozzle, and adjustable water temperature and pressure—all for under $600. The 770 includes a wireless remote with an LED display that shows water temperature and seat status, plus a “Night Light” that illuminates the bowl in soft blue light.

Smart features are basic but functional. The 770 connects via Bluetooth to the Bio Bidet app, which allows you to save up to three user profiles with preferred settings. It also supports Alexa and Google Assistant through a separate smart plug (not included), but voice control is limited to turning the seat heater on/off. The 2026 model adds “Eco Mode” that reduces standby power to 2 watts when not in use, and a “Quick Clean” function that sprays the nozzle with hot water for 10 seconds before each use. The seat is heated to three levels, and the bidet offers front and rear wash with oscillating and pulsating modes.

Pros:

• Unbeatable price for the feature set
• Easy installation (no plumber required)
• Long warranty (3 years parts, 1 year labor)
• Energy-efficient standby mode

Cons:

• No warm air dryer (must use toilet paper or towel)
• Bluetooth range is limited (30 feet max)
• App interface is clunky and slow
• No auto-flush or lid detection

Verdict: The Ultimate 770 is the ideal entry-level smart toilet upgrade. It lacks the premium feel of TOTO or Kohler, but for under $600, you get heated seating, a bidet, and basic smart connectivity. Perfect for renters or those on a tight budget.

Key Features to Consider

When shopping for a smart toilet in 2026, these are the features that matter most:

Buying Guide

Who Should Buy Which Model?

• The Luxury Seeker (TOTO Neorest NX2): If you’re building a custom home or remodeling a master bathroom and budget is no object, the NX2 is the clear winner. Its health monitoring, Matter protocol support, and AI-driven seat prewarming make it a true smart home centerpiece. Ideal for tech enthusiasts who want everything integrated.

• The Practical Upgrader (Kohler PureWash E930): This is the sweet spot for most homeowners. If you have a relatively new toilet (under 10 years old) and want to add bidet functionality, heated seating, and smart home controls without replacing the entire unit, the E930 delivers. The warm air dryer is a game-changer for reducing toilet paper use.

• The Budget-Conscious Buyer (Bio Bidet Ultimate 770): Renters, college students, or anyone on a tight budget will appreciate the 770. It’s a no-fuss upgrade that provides the core smart toilet benefits—heated seat, bidet, and basic smart controls—without breaking the bank. Just be prepared for a clunky app experience.

Budget Considerations

• Under $600: Expect basic bidet seats with heated seating and manual controls. Smart features are limited to Bluetooth apps and basic voice control through third-party plugs.
• $1,000 – $2,000: This range offers the best value. You get warm air dryers, self-cleaning nozzles, Wi-Fi connectivity, and reliable smart home integration (Alexa/Google). Kohler and TOTO’s mid-range models dominate here.
• $3,000 – $6,000: Integrated smart toilets with auto-open/close lids, health monitoring, Matter protocol support, and premium ceramic finishes. These are serious investments but offer the most seamless experience.

Installation & Smart Home Integration

Installation Overview

• Bidet Seats (Kohler E930, Bio Bidet 770): These are DIY-friendly. You’ll need a standard electrical outlet within 3 feet of the toilet (GFCI protected), a T-adapter for the water supply line, and basic tools (wrench, screwdriver). Most models include detailed instructions and video tutorials. Expect 30-60 minutes for installation.
• Integrated Toilets (TOTO NX2): Professional installation is strongly recommended. These units require a dedicated 110V outlet, a water supply line with a shut-off valve, and precise leveling. Plumbers typically charge $200-$400 for installation, depending on your location. The NX2 also requires a 2-inch drain line (standard in most US homes).

Smart Home Integration

• TOTO Neorest NX2: Full Matter protocol support means it works natively with Apple HomeKit, Amazon Alexa, and Google Home. You can create automations like “When I arrive home, preheat the seat” or “When the bathroom occupancy sensor detects no one for 5 minutes, close the lid and flush.” The TOTO Wellness app syncs health data to Apple Health and Google Fit.
• Kohler PureWash E930: Uses Kohler Konnect (Wi-Fi). Works with Alexa and Google Assistant for basic voice commands. The app allows scheduling and user profiles but lacks advanced automations like geofencing.
• Bio Bidet Ultimate 770: Bluetooth only. The app is basic—you can save profiles and adjust settings, but there’s no voice control out of the box. A third-party smart plug can enable basic on/off voice commands for the seat heater.

Pro Tip: If smart home integration is your priority, invest in a model with Matter or native Wi-Fi support. Bluetooth-only models are frustratingly limited.

Conclusion & Final Verdict

After extensive testing, I can confidently say that 2026 is a golden age for smart toilets. The technology has matured: bidet functionality is reliable, self-cleaning nozzles are effective, and smart home integration is finally seamless (thanks to Matter). The choice ultimately comes down to your budget and tolerance for DIY.

My Top Pick: The Kohler PureWash E930 wins for its balance of features, price, and smart home compatibility. It’s the smart toilet upgrade that 90% of homeowners should buy. The warm air dryer alone is worth the price, and the Wi-Fi connectivity ensures it works with your existing smart home ecosystem.

The Splurge: If you have the budget, the TOTO Neorest NX2 is the most luxurious smart toilet I’ve ever tested. The health monitoring features are genuinely useful (I’ve improved my hydration habits because of it), and the Matter protocol support makes it a true smart home device.

The Budget Winner: The Bio Bidet Ultimate 770 proves you don’t need to spend a fortune to enjoy a heated seat and bidet. It’s the perfect entry point for smart toilet newcomers.

Regardless of which model you choose, upgrading to a smart toilet is one of the most impactful smart home improvements you can make. The daily comfort, improved hygiene, and reduced toilet paper usage (up to 75% reduction with a warm air dryer) make it a worthwhile investment. In 2026, there’s no excuse for a cold, manual toilet seat.
