Let’s flush away the confusion and find your perfect match.

Top 3 Product Recommendations

1. TOTO Neorest NX2 (2026 Edition)

Overview: TOTO continues to dominate the luxury smart toilet segment, and the Neorest NX2 is their flagship model for 2026. This unit combines Japanese engineering precision with cutting-edge smart home integration. It features TOTO’s signature Tornado Flush system, which uses dual nozzles to create a powerful, quiet, and water-efficient flush. The NX2 also includes an upgraded eWater+ system that electrolyzes tap water to create a natural cleansing agent, reducing the need for harsh chemicals.

Key Features:

• Washlet+ Technology: Integrated bidet with oscillating, pulsating, and wide-angle spray patterns.
• Premist+: Automatically mists the bowl before use to prevent waste from sticking.
• Auto-Open/Close Lid: Motion sensors detect your approach and adjust the lid and seat automatically.
• Heated Seat with Temperature Memory: Customizable to your preferred warmth.
• Air Dryer with Dual Fans: Faster, quieter drying than previous models.
• Smart Home Compatibility: Works with Amazon Alexa, Google Assistant, and Apple HomeKit via the TOTO SmartHub app. You can adjust settings, monitor water usage, and receive maintenance alerts remotely.

Performance: In testing, the NX2’s flush was virtually silent yet powerful enough to handle heavy waste with a single flush. The bidet spray is precise and adjustable, with a warm water heater that responds instantly. The heated seat is a game-changer in colder months, and the auto-open feature is responsive without being overly sensitive.

Pros: Exceptional build quality, quiet operation, extensive smart features, water-saving (1.0 GPF). Cons: High price point (around $5,500), requires professional installation, limited color options (only white and bone).

Who It’s For: Homeowners who want the best of the best and are willing to invest in a premium, long-lasting fixture. Ideal for master bathrooms or high-traffic guest bathrooms where comfort and hygiene are paramount.

2. Kohler PureWash E930

Overview: Kohler’s PureWash E930 is a strong contender in the mid-to-premium range, offering a sleek design and robust feature set without the exorbitant price tag of the TOTO. This model is a one-piece toilet with an integrated bidet seat, designed for easy cleaning and modern aesthetics. It features Kohler’s AquaPiston flush technology, which delivers a consistent, powerful flush from all angles.

Key Features:

• Dual-Flush Option: 1.28 GPF for liquid waste, 1.6 GPF for solid waste, saving water without sacrificing performance.
• UV-Cleaning Nozzle: Uses ultraviolet light to sanitize the bidet wand after each use.
• Warm Air Dryer: Adjustable temperature and speed, with a cool-touch seat.
• Remote Control: Wireless, wall-mountable remote with backlit buttons for easy night use.
• Voice Control: Compatible with Amazon Alexa and Google Assistant for hands-free operation (e.g., “Alexa, flush the toilet”).
• Soft-Close Seat and Lid: Prevents slamming and reduces noise.

Performance: The PureWash E930 delivers a satisfying flush with minimal noise. The bidet spray is gentle yet effective, with a front-and-back wash option that’s easy to toggle. The UV cleaning is a nice touch for hygiene enthusiasts. The remote is intuitive, though the lack of a dedicated app for deeper customization is a minor downside.

Pros: Excellent value for features, reliable flush, UV sanitation, voice control. Cons: No automatic lid opening (manual only), air dryer could be stronger, seat is slightly narrower than some competitors.

Who It’s For: Tech-savvy homeowners who want smart features without breaking the bank. Great for families or couples who value hygiene and convenience.

3. BioBidet Ultimate 770

Overview: BioBidet may not be a household name like TOTO or Kohler, but the Ultimate 770 is a standout in the smart toilet seat category. This is a bidet seat attachment that can be retrofitted onto most standard toilets, making it an affordable entry point into smart bathroom tech. The 2026 version includes upgraded sensors and a more powerful dryer.

Key Features:

• Heated Seat with Five Temperature Settings: Customizable for year-round comfort.
• Enema Wash: A focused, high-pressure stream for medical needs or thorough cleansing.
• Stainless Steel Nozzle: Self-cleaning with an adjustable position.
• Instant Warm Water: On-demand heating ensures no cold water surprises.
• Wireless Remote: Backlit, with a large display for easy reading.
• Smart Home Integration: Works with Alexa and Google Assistant for basic commands (flush, seat heat, wash). Also includes a motion sensor for automatic flush when you stand up.

Performance: The Ultimate 770 is surprisingly feature-rich for its price. The enema wash is powerful but can be startling if you’re not prepared—use the lower pressure setting first. The seat heating is consistent, and the dryer is effective, though not as fast as the TOTO. Installation is straightforward for DIYers, taking about 30 minutes.

Pros: Affordable (around $400), easy installation, extensive wash options, good smart home support. Cons: Not as sleek as integrated toilets, needs a power outlet near the toilet, remote can be bulky.

Who It’s For: Renters or homeowners on a budget who want smart toilet features without replacing their entire toilet. Also ideal for those with specific medical needs (e.g., hemorrhoids, post-surgery recovery).

Buying Guide

Who Should Buy a Smart Toilet?

• Luxury Seekers: If you want the pinnacle of comfort and tech, the TOTO Neorest NX2 is unmatched. It’s an investment in daily luxury and can increase home value.
• Practical Upgraders: The Kohler PureWash E930 is perfect for families who want reliable performance, voice control, and water savings without the premium price.
• Budget-Conscious or Renters: The BioBidet Ultimate 770 offers 90% of the features at a fraction of the cost. It’s easy to remove when you move, making it ideal for apartments.

Budget Considerations

• Under $500: Stick with bidet seat attachments like the BioBidet or TOTO Washlet S550e. You’ll get heated seats, bidet, and dryer, but no auto-open or app control.
• $1,000 – $3,000: Mid-range integrated models like the Kohler PureWash or American Standard VorMax. These offer good build quality, dual-flush, and basic smart features.
• $3,000+: Premium integrated toilets like the TOTO Neorest or Duravit SensoWash. Expect full automation, advanced hygiene systems, and seamless smart home integration.

Hidden Costs: Don’t forget installation (professional install can run $200–$500), electrical work (need an outlet near the toilet), and potential modifications to your plumbing (especially for integrated models).

Installation & Smart Home Integration

Installation

• Integrated Smart Toilets: These require professional installation. You’ll need a dedicated electrical outlet (GFCI protected) and a standard water supply line. The toilet must be level and securely anchored. Expect 2–4 hours for a pro install.
• Bidet Seats: Much simpler. Turn off water, remove existing seat, attach bidet seat, connect water supply, plug in power. Most DIYers can do this in 30–60 minutes. Just ensure your toilet bowl is elongated or round—check compatibility.

Smart Home Integration

All three recommended models support voice assistants, but integration depth varies:

• TOTO: The SmartHub app lets you create schedules (e.g., seat heating on at 7 AM), monitor water usage, and get leak alerts. Works with Alexa routines.
• Kohler: Voice control is basic—you can flush, heat seat, and start wash. No app for deeper control.
• BioBidet: Similar to Kohler but also supports IFTTT for more advanced automation (e.g., turn on bidet when motion sensor triggers).

Pro Tip: For full smart home integration, pair your smart toilet with a humidity sensor or smart exhaust fan. For example, create a routine: “When toilet flushes, turn on bathroom fan for 10 minutes.”

Conclusion & Final Verdict

The smart toilet market in 2026 offers something for everyone, from the budget-conscious renter to the luxury homeowner. After extensive testing, my top recommendation is the Kohler PureWash E930 for most buyers. It strikes the perfect balance between features, price, and reliability. You get a powerful flush, a comfortable bidet, voice control, and UV sanitation—all without the eye-watering cost of the TOTO.

If budget is no object and you want the absolute best, the TOTO Neorest NX2 is the gold standard. Its self-cleaning, auto-opening, and app integration are second to none. For those on a tight budget or in a rental, the BioBidet Ultimate 770 is a steal, offering impressive functionality for a fraction of the price.

Whichever you choose, a smart toilet will elevate your bathroom experience, reduce toilet paper usage, and improve personal hygiene. It’s one of those upgrades you’ll wonder how you lived without. So go ahead—embrace the future of bathroom technology. Your posterior will thank you.

Final Verdict:

• Best Overall: Kohler PureWash E930
• Best Premium: TOTO Neorest NX2
• Best Value: BioBidet Ultimate 770
