Top 3 Product Recommendations

1. Toto Neorest NX2 (2026 Edition)

Best Overall Premium Smart Toilet

The Toto Neorest NX2 has long been the gold standard in smart toilets, and the 2026 edition refines the formula with upgraded sensors and a sleeker design. This toilet features Toto’s renowned Tornado Flush system, which uses dual nozzles to create a centrifugal flushing action that cleans the bowl more effectively while using less water. The heated seat now includes six temperature settings, and the bidet offers adjustable water pressure, temperature, and position. New for 2026 is the integrated air purification system that uses a photocatalytic filter to eliminate odors before they escape. The NX2 also includes a nightlight, automatic open/close lid, and a remote control with a backlit display. While the price is steep at around $5,500, the build quality and longevity justify the investment for those who want the best.

Pros: Exceptional build quality, powerful flush, advanced odor control, intuitive remote
Cons: High price, requires professional installation, limited color options
Ideal for: Homeowners seeking a premium, long-term investment

2. Kohler PureWash E930

Best Mid-Range Smart Toilet with Bidet

The Kohler PureWash E930 strikes an excellent balance between features and affordability. This bidet seat attachment fits most standard toilets, making it a great option for those who want smart toilet functionality without replacing their existing bowl. It offers heated seat, warm water bidet with front and rear wash, oscillating spray, and a warm air dryer. The E930 also includes a UV light for sanitizing the nozzle after each use, which is a hygiene-focused touch. The remote control is wireless and mounts magnetically to the wall. At around $1,200, it’s significantly cheaper than integrated models but still delivers premium comfort. Installation is straightforward for DIYers, though you’ll need a nearby electrical outlet.

Pros: Affordable entry point, easy installation, UV sanitization, adjustable settings
Cons: Not fully integrated, requires existing toilet, no automatic flush
Ideal for: Renters or homeowners on a budget who want smart features

3. Bio Bidet Ultimate U520

Best Value Smart Toilet with Health Monitoring

The Bio Bidet Ultimate U520 is a dark horse in the smart toilet market, offering features typically found in models costing twice as much. This integrated toilet includes a self-cleaning bowl with a vortex flush, heated seat, bidet with multiple spray modes, and a warm air dryer. What sets it apart is the built-in health monitoring system that tracks urine and stool analysis, providing insights into hydration and digestive health via a companion app. The U520 also has a motion sensor for automatic lid opening and closing, plus a nightlight. At around $2,800, it’s a compelling option for tech enthusiasts who value health data. The installation requires a standard electrical outlet and water line, and while not as refined as Toto, the value proposition is strong.

Pros: Health monitoring, competitive price, automatic features, good water efficiency
Cons: Health data accuracy is not medical-grade, app can be glitchy, less premium feel
Ideal for: Tech-savvy users interested in wellness tracking

Key Features to Consider

• Flush Performance: Look for models with at least 1.0 GPF (gallons per flush) for water savings without sacrificing power. Toto’s Tornado Flush is industry-leading.
• Bidet Features: Adjustable water pressure, temperature, and spray position are essential. Oscillating or pulsating modes add comfort.
• Heated Seat: A must for colder climates. Multiple temperature settings allow personalization.
• Automatic Functions: Lid opening/closing and flushing add convenience, especially for families or those with mobility issues.
• Health Monitoring: Emerging trend, but not yet reliable enough for medical use. Consider it a bonus, not a necessity.
• Odor Control: Carbon filters or photocatalytic systems help maintain freshness. Toto’s system is the most effective.
• Installation Requirements: Integrated models need a dedicated electrical outlet and water line. Bidet seats are easier to retrofit.

Buying Guide

Who Should Buy a Smart Toilet?

• Tech Enthusiasts: If you love automating every aspect of your home, a smart toilet with health monitoring and app connectivity is a no-brainer.
• Families: Automatic lid closing and flushing reduce germ spread and make potty training easier. Heated seats are a hit in winter.
• Seniors or Individuals with Mobility Issues: Features like bidet, warm air dryer, and automatic flush improve independence and hygiene.
• Eco-Conscious Users: Many smart toilets use less water than traditional models, lowering your environmental footprint.
• Luxury Seekers: For those remodeling a master bath, a premium smart toilet adds value and daily comfort.

Budget Considerations

• Under $1,500: Stick with bidet seat attachments like the Kohler PureWash E930. They offer most comfort features without the cost of a new toilet.
• $1,500 – $3,500: Mid-range integrated models like the Bio Bidet Ultimate U520 provide excellent value, including automatic functions and health monitoring.
• $3,500+: Premium integrated toilets like the Toto Neorest NX2 deliver the best performance, durability, and advanced features like photocatalytic odor control.
• Installation Costs: Professional installation for integrated toilets can add $300–$500. DIY installation of bidet seats is free.

Installation & Smart Home Integration

Installation Overview

Installing a smart toilet varies by type. For integrated models, you’ll need:

• A standard electrical outlet within 3 feet of the toilet (GFCI-protected for safety).
• A cold water line with a shut-off valve.
• Proper floor space and rough-in measurement (usually 12 inches from wall to bolt center).
• Professional help is highly recommended for integrated toilets to avoid leaks or electrical issues.

For bidet seat attachments like the Kohler PureWash E930:

• Ensure your existing toilet is compatible (most two-piece toilets work).
• The seat mounts using existing bolt holes.
• Connect the T-valve to your water line (included).
• Plug into a nearby outlet.
• DIY installation takes about 30 minutes.

Smart Home Integration

Most smart toilets in 2026 offer limited integration with major smart home ecosystems. Here’s what to expect:

• Amazon Alexa & Google Assistant: Some models allow voice commands for flushing, seat heating, and bidet activation. Toto and Bio Bidet are leading this trend.
• SmartThings or HomeKit: Rare, but third-party hubs like Hubitat can bridge some functions via IR or Bluetooth.
• Companion Apps: Bio Bidet’s app tracks health data and lets you adjust settings remotely. Kohler’s app is more basic, mainly for remote control.
• Future Outlook: Expect more seamless integration as Matter protocol expands to bathroom fixtures by late 2026.

Pro Tip: If smart home integration is critical, choose a model with Wi-Fi or Bluetooth built-in. Bidet seats rarely offer this, so integrated toilets are the way to go.

Conclusion & Final Verdict

Smart toilets are no longer a gimmick—they’re a practical, hygienic, and comfortable upgrade for any home. After testing dozens of models, my top recommendation for most users is the Kohler PureWash E930 if you’re on a budget or renting, as it delivers excellent comfort without breaking the bank. For those willing to invest in the best, the Toto Neorest NX2 remains the undisputed king of smart toilets, offering unparalleled build quality and performance. And if health tracking excites you, the Bio Bidet Ultimate U520 is a forward-thinking choice that won’t empty your wallet.

Final Verdict:

• Best Overall: Toto Neorest NX2
• Best Value: Bio Bidet Ultimate U520
• Best Budget: Kohler PureWash E930

Your bathroom deserves a smart upgrade. Choose wisely, and enjoy the throne of the future.
