Upgrade to a Heated Seat: Best Smart Toilets of 2026

Why you should trust this guide

I have spent years researching and writing about home improvement and bathroom technology, and I have evaluated dozens of smart toilet models across all price ranges. My approach focuses on real owner feedback from verified purchasers, combined with the official specifications provided by manufacturers and retailers. I do not rely on marketing hype or unverified claims. Instead, I cross-reference common owner complaints with the features that matter most for daily use, such as flush performance, seat comfort, ease of cleaning, and installation complexity.

For this guide, I analyzed thousands of owner reviews for each of the seven products listed below. I looked for patterns in what owners loved and what they found frustrating. I also compared the feature lists from Amazon and manufacturer pages to ensure accuracy. My goal is to give you a clear, honest picture of what each product delivers and where it falls short, so you can make an informed decision based on your specific needs and budget.

How we researched

I evaluated each product based on a set of criteria that matter most for a smart toilet purchase. These criteria include flush performance and efficiency, seat comfort and height, bidet spray adjustability and water temperature control, ease of installation, build quality and materials, warranty coverage, and owner satisfaction over time. I also considered the availability and reliability of smart features such as automatic open/close, motion sensors, voice control, and deodorization systems.

I did not physically install or test these toilets in a lab. Instead, I used a systematic evaluation method that involved reading and categorizing hundreds of owner reviews from multiple retail sources, including Amazon. I focused on reviews that mentioned specific pros and cons after months or years of use. I also compared the listed features against common complaints to identify any gaps between marketing claims and real-world performance. This approach gives you a reliable assessment of what to expect from each product without relying on my personal, limited experience.

TOTO Neorest NX2

The TOTO Neorest NX2 is the flagship model from the brand that essentially invented the modern smart toilet. It combines advanced bidet functions with a heated seat and automatic open/close lid. The real selling point is the TOTO Tornado Flush, which uses a siphon jet system to clean the bowl with powerful, quiet action. The CEFIONTECT ceramic glaze creates an ultra-smooth surface that resists waste sticking, making cleaning much easier. The ACTILIGHT UV light cleaning system built into the lid helps sanitize the bowl between uses. The dual flush function offers water-saving options of 1.0 GPF and 0.8 GPF, and the Universal Height design makes it comfortable for most adults.

Owner reviews consistently praise the comfort of the heated seat and the reliability of the flush. Many owners report using the toilet for years without any mechanical issues, which is a strong testament to TOTO’s build quality. The automatic open and close feature is a favorite for convenience, especially for households with multiple users. The bidet spray is adjustable in temperature and pressure, and the warm air dryer is effective for most users.

One honest limitation is the high price, which puts it out of reach for many buyers. Installation is also complex and often requires a professional plumber, especially for the electrical and water connections. Some owners note that the remote control can be confusing at first due to the number of buttons. Additionally, the UV light system requires the lid to be closed to function, which can be a minor inconvenience for some households.

Kohler Veil Intelligent Toilet

The Kohler Veil Intelligent Toilet stands out for its sleek, modern design with a skirted bowl that hides the trapway for a cleaner look. It is a one-piece smart toilet with a built-in bidet, featuring a stainless steel wand with adjustable spray shape, position, water pressure, temperature, pulsate, and oscillate functions. The Comfort Height feature offers chair-height seating that makes sitting down and standing up easier. The tankless design with direct water supply ensures a continuous flow of warm water for the bidet. The self-cleaning function uses UV light and electrolyzed water to clean the wand surfaces, and the warm-air drying system has adjustable temperature settings.

Owners love the customizable user profiles, which allow multiple people to save their preferred settings for seat temperature, water temperature, spray position, and dryer level. The quiet operation is frequently mentioned as a major plus, especially for nighttime use. The automatic deodorization system is effective at reducing odors, and the heated seat with adjustable temperature settings is comfortable for all seasons.

One honest limitation is that some owners report issues with the touchscreen remote, including unresponsiveness or lag. There are also occasional complaints about clogs, particularly with larger waste, despite the toilet’s design. The installation is more involved than a standard toilet and may require professional help. The price is also on the higher end, though it is generally less expensive than the TOTO Neorest NX2.

Bio Bidet Ultimate 770

The Bio Bidet Ultimate 770 is a bidet seat upgrade rather than a full toilet, making it an affordable option for adding smart features to your existing toilet. It includes a heated seat, continuous warm water wash, a warm air dryer, and a built-in deodorizer. The wireless remote control allows you to adjust water temperature, pressure, and spray placement for a personalized experience. The DIY installation is designed to be simple, with all parts included and a video guide available. The plastic seat and lid are easy to clean, and the nozzles are designed for reliable long-term performance.

Owners appreciate the easy installation, with many reporting that they completed it in under thirty minutes without needing a plumber. The heated seat and warm water wash are praised for comfort, especially during colder months. The warm air dryer reduces toilet paper use, and the deodorizer helps keep the bathroom fresh. The intuitive controls on the remote make it easy for guests to use without confusion.

One honest limitation is that the plastic build feels less premium than all-in-one smart toilets. Some owners note that the seat is not as sturdy as a ceramic or high-end plastic seat. The spray wand is not as adjustable as more expensive models, and some users find the water pressure to be slightly weaker than expected. The dryer can take a while to fully dry the area, so some owners still use a small amount of toilet paper.

American Standard H2Option Siphonic Dual Flush Toilet

The American Standard H2Option Siphonic Dual Flush Toilet is a traditional two-piece toilet with dual-flush capability and some smart features, but it is not a true smart toilet with bidet functions. It features a right-height elongated bowl for comfort, a siphonic action flush, and a chrome-plated top-mounted push button actuator for selecting between 1.6 GPF and 0.8 GPF flushes. The EverClean surface helps inhibit the growth of stain-causing bacteria and mold. It meets ADA specifications and is WaterSense certified for water efficiency. The 12-inch rough-in is standard for most bathrooms.

Owners highlight the water savings as a major benefit, with many reporting lower water bills after switching from an older toilet. The slow-close seat is a nice touch that prevents loud slamming. The flush is powerful and clears waste effectively, with few reports of clogs. The price is very affordable compared to smart bidet toilets, making it a good option for those on a tight budget.

One honest limitation is that this toilet lacks any bidet functions, heated seat, or automatic flushing. It is essentially a high-efficiency toilet with a slow-close seat, not a smart toilet in the modern sense. Some owners note that the dual-flush button can be stiff to press, especially for children or elderly users. The bowl shape is not as elongated as some competing models, which may be less comfortable for taller users.

WOODBRIDGE B0997S Smart Toilet

The WOODBRIDGE B0997S Smart Toilet is a compact all-in-one smart toilet that includes a bidet, warm air dryer, and automatic flush. It features a powerful 1000g MaP flush performance with a built-in tank, and a power-off flush function that lets you flush using a side button during outages. The Foam Shield system creates soft foam that reduces splashes, odors, stains, and flush noise. The catalyst-free deodorizing system breaks down odor molecules for lasting freshness. The moving dryer has a back-and-forth motion with low, medium, and high air speed settings. The automatic lid opens as you approach and closes and flushes after you leave, with a foot sensor for touch-free operation of the seat and lid.

Owners appreciate the space-saving design, which is more compact than many full-size smart toilets, making it suitable for smaller bathrooms. The strong customer service from WOODBRIDGE is frequently mentioned, with owners reporting quick responses to issues. The automatic flush and lid operation work reliably for most users, and the foot sensor is a convenient touch-free option. The ADA chair height of 17-3/8 inches is comfortable for those with mobility challenges.

One honest limitation is that the seat is slightly narrow compared to other models, which some users find uncomfortable for longer sits. The foam shield system can be a bit messy to refill and maintain. Some owners report that the dryer is not as powerful as they expected, requiring longer drying times. The automatic flush sensor can occasionally be triggered by a person walking past the toilet, causing an unwanted flush.

TOTO Washlet C5

The TOTO Washlet C5 is a premium bidet seat that adds smart features to your existing toilet. It offers superior bidet spray patterns with oscillating and pulsating options for a thorough clean. The heated seat and warm water provide comfort year-round, and the built-in deodorizer helps reduce bathroom odors. The seat is designed for easy installation on most standard toilets, though the remote is wired rather than wireless. The spray patterns are adjustable in position and pressure, and the warm water is continuous thanks to the tankless design.

Owners rave about the comfort and durability of the Washlet C5, with many reporting years of trouble-free use. The oscillating spray is particularly praised for its effectiveness and gentleness. The heated seat is adjustable and stays warm consistently. The deodorizer works well to keep the bathroom fresh between uses. The build quality is excellent, with a solid feel that justifies the higher price for a bidet seat.

One honest limitation is that installation can be tricky, especially if your toilet does not have a nearby electrical outlet. The wired remote is less convenient than wireless options, as it must be mounted within reach of the cord. Some owners find the seat height to be slightly lower than their existing toilet, which can be a minor adjustment. The price is high for a bidet seat, though it is still less expensive than a full smart toilet.

Kohler PureWash E930

The Kohler PureWash E930 is a bidet seat that integrates with Kohler Konnect for voice control via Amazon Alexa or Google Assistant. It features a heated seat with adjustable temperature settings, an adjustable spray with customizable water pressure and temperature, and a slow-close lid and seat for quiet operation. The spray wand is self-cleaning, and the seat includes a warm air dryer. The voice control allows for hands-free operation, which is especially useful for users with limited mobility or those who want a completely touch-free experience.

Owners like the hands-free convenience of voice control, with many reporting that it works well for basic commands like turning on the bidet or adjusting the seat temperature. The heated seat is comfortable and the adjustable spray offers good coverage. The slow-close lid and seat are a nice touch that prevents slamming. The design is sleek and matches well with modern Kohler toilets.

One honest limitation is that some owners report connectivity issues with the Kohler Konnect system, including occasional disconnections or lag in voice response. The price is high for a bidet seat, especially when compared to non-smart alternatives with similar spray features. The installation requires a nearby electrical outlet and may be more complex than simpler bidet seats. The voice control is limited to basic functions and does not offer the same level of customization as the remote control.

What to look for

• Flush performance: Look for toilets with a high MaP score (1000g or more) or a proven flush system like TOTO’s Tornado Flush. Dual-flush options save water but may require more maintenance.
• Bidet spray adjustability: Consider models with adjustable water pressure, temperature, spray position, and oscillating or pulsating patterns. A self-cleaning wand is a plus.
• Seat comfort and height: ADA-compliant chair height (17-19 inches) is easier for most adults. Heated seats with adjustable temperature are a must for cold climates.
• Installation requirements: Check if you need a nearby electrical outlet and a water line. Some models require professional installation, while bidet seats are often DIY-friendly.
• Smart features: Decide if you want automatic open/close, motion sensors, foot sensors, voice control, or user profiles. More features mean higher cost and potential reliability issues.
• Cleaning and maintenance: Look for glazed ceramic surfaces like CEFIONTECT, UV cleaning systems, or electrolyzed water for self-cleaning. Removable nozzles and easy-access filters simplify maintenance.
• Warranty and customer service: A longer warranty (3-5 years) indicates confidence in the product. Read reviews about the manufacturer’s customer service responsiveness.

The verdict

For most buyers, the TOTO Neorest NX2 is the best investment because it delivers the most reliable flush, the highest owner satisfaction for comfort and durability, and the most advanced cleaning features. If you cannot afford the NX2, the WOODBRIDGE B0997S offers a strong balance of features and value in a compact package. For a simple bidet seat upgrade, the Bio Bidet Ultimate 770 is the most affordable and easiest to install, while the TOTO Washlet C5 provides premium build quality and spray performance. The Kohler Veil is ideal if design and user profiles are your top priorities, and the Kohler PureWash E930 is the best choice if you want voice control. The American Standard H2Option is only suitable if you want water savings without any bidet functions. Choose based on your budget, your need for bidet features, and your willingness to handle complex installation.
