Top 3 Smart Toilet Recommendations for 2026

1. TOTO Neorest NX2 (Editor's Choice: Best Overall)

Price: $8,900 - $9,500

When it comes to smart toilets, TOTO remains the undisputed king, and the Neorest NX2 represents the pinnacle of their engineering. This is the toilet that other manufacturers benchmark against, and for good reason.

Design and Build Quality

The NX2 features a sleek, one-piece design with a skirted trapway that not only looks premium but makes cleaning significantly easier. The glazed ceramic finish is exceptionally smooth, preventing debris from adhering to the surface. The lid opens and closes automatically as you approach, which feels futuristic even after months of use.

Performance and Features

The star of the show is TOTO's proprietary eWater+ system, which uses electrolyzed water to break down waste before flushing. This isn't just marketing hype-it genuinely reduces the amount of water needed per flush (a mere 0.8 gallons for liquid waste) while keeping the bowl remarkably clean. The ACTIVE360 washing system provides a comprehensive spray pattern that's both gentle and effective.

The bidet functions offer adjustable water temperature, pressure, and position, with a dedicated "soft" mode for sensitive users. The warm air dryer is surprisingly powerful, and the heated seat features multiple temperature settings. The automatic flush, deodorizing system, and pre-mist function round out a feature set that feels complete.

Smart Home Integration

Where the NX2 truly excels is its integration capabilities. It works with Alexa and Google Assistant, allowing you to control settings via voice commands. The TOTO app provides usage analytics and allows for granular customization of all functions. It even has a night light that activates based on ambient lighting conditions.

Verdict

The Neorest NX2 is expensive, there's no denying that. But if you want the absolute best smart toilet experience with proven reliability (TOTO has been perfecting this technology for decades), this is the gold standard. The build quality is exceptional, and the feature set is unmatched.

Pros:

• Exceptional build quality and durability
• Advanced eWater+ cleaning technology
• Comprehensive smart home integration
• Industry-leading bidet performance

Cons:

• Very expensive
• Requires professional installation
• May be overkill for some users

2. Kohler Numi 2.0 (Best for Luxury Features)

Price: $7,500 - $8,200

Kohler's Numi 2.0 is the smart toilet that makes headlines, and it's easy to see why. This is the toilet that does everything except make you breakfast (though at this price, you might expect it to).

Design and Build Quality

The Numi 2.0 is a statement piece. Its minimalist, rectangular design is a departure from traditional toilet aesthetics, making it a conversation starter in any bathroom. The ceramic quality is excellent, and the unit feels substantial and well-constructed. The lid is made of a high-quality polymer that resists scratches and fingerprints.

Performance and Features

The Numi 2.0's party trick is its built-in speaker system with Bluetooth connectivity. You can play music or podcasts directly from the toilet, which is either a brilliant feature or completely unnecessary depending on your perspective. It also features a customizable LED light show with multiple color options-perfect for creating a spa-like atmosphere.

The bidet functions are comprehensive, with adjustable temperature, pressure, and oscillating/pulsating modes. The heated seat is exceptionally comfortable, and the dryer is among the best I've tested. Kohler's "Quiet Close" technology ensures the lid and seat close with a whisper-quiet operation.

Smart Home Integration

The Numi 2.0 offers excellent voice control through Alexa and Google Assistant. You can say "Alexa, tell the toilet to warm the seat" and it will comply. The Kohler Konnect app provides full control over all settings, including creating custom user profiles. The toilet can even be programmed to respond to motion sensors, automatically raising the lid when you approach.

Verdict

The Numi 2.0 is a luxury statement piece that offers the most entertainment value of any smart toilet. If you want a bathroom that impresses guests and delivers a premium experience, this is a top contender. However, the speaker and light features feel more gimmicky than essential, and you're paying a premium for them.

Pros:

• Unique, futuristic design
• Built-in Bluetooth speaker
• Customizable LED lighting
• Excellent voice control integration

Cons:

• Speaker and lights feel gimmicky
• Premium price for non-essential features
• Not as water-efficient as TOTO

3. Bio Bidet BB-2000 (Best Value)

Price: $1,200 - $1,400

For those who want smart toilet features without the luxury price tag, the Bio Bidet BB-2000 is the clear winner. This is a bidet seat attachment that can be paired with your existing toilet, offering most of the essential features of high-end models at a fraction of the cost.

Design and Build Quality

The BB-2000 is designed to fit most standard two-piece toilets, making it an excellent option for renters or homeowners who don't want to replace their entire fixture. The seat is constructed from durable polypropylene and features a sleek, low-profile design that doesn't look out of place in a modern bathroom.

Performance and Features

Despite its affordable price, the BB-2000 punches well above its weight class. It offers a heated seat with adjustable temperature, warm water bidet with multiple spray patterns, and a warm air dryer. The oscillating and pulsating massage modes are genuinely effective and comparable to units costing three times as much.

The water filtration system includes a sediment filter and a self-cleaning nozzle that retracts and sanitizes after each use. The instant water heating system ensures you never run out of hot water, even during extended sessions.

Smart Home Integration

This is where the BB-2000 falls short of its premium competitors. It doesn't offer native smart home integration, but it does come with a wireless remote control that provides full control over all functions. You can program up to two user presets for personalized settings. For those who want voice control, it's compatible with smart plugs, though this limits functionality to on/off control.

Verdict

The Bio Bidet BB-2000 offers the best value proposition in the smart toilet market. It provides 80% of the features of $5,000+ toilets at 20% of the price. If you're new to smart toilets or working with a limited budget, this is the smartest choice you can make.

Pros:

• Exceptional value for money
• Easy DIY installation
• Comprehensive feature set
• Compatible with most standard toilets

Cons:

• No native smart home integration
• Not as aesthetically premium as integrated units
• Remote control can be lost or misplaced

Key Features to Consider

When shopping for a smart toilet, understanding the features that truly matter is crucial. Here's a breakdown of what to look for:

Comparison Table: Essential Smart Toilet Features

Bidet Functionality

The bidet is the heart of any smart toilet. Look for adjustable water temperature, pressure, and spray position. Oscillating and pulsating modes provide a more thorough clean. Some models offer a "feminine wash" setting with a wider spray pattern for women.

Heated Seat

This is often the first feature people fall in love with. Look for multiple temperature settings and a seat that heats up quickly. Some premium models offer a "sensor" mode that pre-heats the seat when it detects your approach.

Drying System

A good dryer should be powerful enough to actually eliminate the need for toilet paper (though most users still use some). Look for adjustable temperature and airflow settings.

Odor Control

Activated carbon filters are effective at neutralizing odors. Ozone-based systems are more powerful but require additional maintenance. Some models automatically activate the deodorizer when the seat is occupied.

Water Efficiency

Smart toilets should be more efficient than their traditional counterparts. Look for models with dual-flush capabilities and low GPF (gallons per flush) ratings. The most efficient models use less than 1.0 GPF for liquid waste.

Smart Features

Consider which smart features are essential for you. Voice control is convenient but not necessary. Usage tracking can be useful for health monitoring. Automatic flushing and lid operation add convenience but also add to the cost.

Buying Guide

Who Should Buy a Smart Toilet?

Ideal for:

• Tech enthusiasts who want to complete their smart home ecosystem
• Individuals with mobility issues who benefit from automatic features and bidet functionality
• Families who can benefit from user presets and personalized settings
• Eco-conscious consumers who want to reduce water usage
• Anyone who values hygiene and wants to reduce toilet paper usage

Not ideal for:

• Budget-conscious buyers who can't justify the premium over traditional toilets
• Renters who can't modify their bathroom fixtures (though bidet seats are an option)
• Those who prefer simple, traditional fixtures
• Homes with outdated plumbing that may not support the additional electrical and water connections

Budget Considerations

Entry Level ($500 - $1,500): At this price point, you're looking at bidet seat attachments or basic integrated smart toilets. You'll get heated seats, basic bidet functions, and perhaps a dryer, but you'll miss out on automatic flush and smart home integration.

Mid-Range ($1,500 - $5,000): This is the sweet spot for most buyers. You'll find integrated smart toilets with comprehensive features, including automatic flush, deodorizers, and some smart home integration. Brands like TOTO, Kohler, and American Standard offer excellent options in this range.

Premium ($5,000+): At this level, you're getting the best of everything-exceptional build quality, advanced features, and full smart home integration. The TOTO Neorest and Kohler Numi are the benchmarks here.

Hidden Costs: Don't forget to factor in installation costs ($200-$500 for professional installation), potential electrical outlet installation ($200-$400), and water line modifications ($100-$300). Extended warranties may also be worth considering for peace of mind.

Installation & Smart Home Integration

Installation Considerations

Electrical Requirements: Smart toilets require a nearby electrical outlet (GFCI-protected). If your bathroom doesn't have one near the toilet, you'll need to hire an electrician. This is often the most significant installation hurdle.

Water Supply: Most smart toilets require a dedicated water supply line. Some models need both cold and hot water connections, while others have internal water heaters and only need cold water.

Professional vs. DIY: Bidet seats can typically be installed by a competent DIYer in under an hour. Integrated smart toilets are heavier and more complex-professional installation is strongly recommended. Expect installation costs between $200-$500.

Space Requirements: Smart toilets are generally larger than traditional models. Ensure you have adequate clearance on all sides. Some models require more space behind the toilet for the control unit.

Smart Home Integration Options

Voice Assistants: Most premium smart toilets work with Amazon Alexa and Google Assistant. Voice commands can control seat temperature, bidet settings, and flushing. This is particularly useful for individuals with mobility issues.

Mobile Apps: Manufacturer apps provide granular control over all settings. You can create user profiles, track usage statistics, and receive maintenance reminders. Some apps offer health monitoring features that track weight, hydration, and other metrics.

Automation: Smart toilets can be integrated into broader home automation routines. For example, you can set the seat to warm up at specific times of day or have the toilet flush when you leave the bathroom.

Compatibility: Before purchasing, verify that the smart toilet is compatible with your existing smart home ecosystem. Most major brands support both Alexa and Google Assistant, but Apple HomeKit compatibility is less common.

TOTO Neorest NX2 remains the top recommendation for those who want the best overall experience. Its combination of proven reliability, advanced features, and excellent smart home integration justifies its premium price tag. If you're investing in a forever home and want a bathroom that will remain cutting-edge for years, this is the choice.

Kohler Numi 2.0 is the luxury option for those who want a statement piece. The speaker and lighting features are unique, and the design is genuinely striking. However, you're paying a premium for features that, while entertaining, aren't essential.

Final Verdict: Smart toilets are no longer a luxury novelty-they're a legitimate upgrade that can improve hygiene, reduce water usage, and add genuine convenience to your daily routine. The technology has matured, prices are becoming more accessible, and the benefits are clear. Whether you choose a premium integrated unit or a budget-friendly bidet seat, upgrading to a smart toilet is an investment that pays dividends in comfort and satisfaction.
