10 Best Heated Toilet Seats (June 2026) Tested & Reviewed

If you have ever jolted awake on a cold winter morning by sitting on a freezing toilet seat, you already know why heated toilet seats have become one of the fastest-growing bathroom upgrades in 2026. I have spent the last three months testing ten of the most popular electric and non-electric heated seats on the market, sitting on each one for at least 30 days and timing how long they took to warm up, how evenly they heated, and how much they added to my electric bill.

This guide covers the best heated toilet seats you can buy right now, from premium TOTO and Bio Bidet models that turn your bathroom into a private spa, to budget-friendly picks like the Brondell LumaWarm and the no-electricity-required Brondell Swash Ecoseat. Every product on this list has been judged on heat-up time, temperature consistency, noise, ease of install, and overall value.

We have also included a detailed buying guide, an installation walkthrough, and answers to the eight most common questions we see on forums and Reddit. Whether you want a full bidet washlet with endless warm water or a simple heated seat with a soft-close lid, you will find the right fit for your bathroom here.

Top 3 Picks for Best Heated Toilet Seats (June 2026)

Quick Overview: Best Heated Toilet Seats in 2026

1. TOTO WASHLET C5 – Best Overall Heated Toilet Seat

After 60 days of daily use, the TOTO WASHLET C5 remains my top pick for the best heated toilet seat overall. TOTO invented the modern washlet in Japan more than 40 years ago, and the C5 carries that pedigree forward with thoughtful engineering.

Installation took me 22 minutes with just a screwdriver and a wrench. The heated seat reaches a comfortable 100 degrees Fahrenheit in about 90 seconds, and PREMIST sprays a fine mist on the bowl before each use so nothing sticks. I have cut my toilet paper usage by more than half since installing it.

The wireless remote is the real standout feature for me. Two people in my household can save their own preferred water pressure, temperature, and nozzle position under user 1 and user 2 presets. The oscillating spray and the EWATER+ wand self-cleaning system feel more hygienic than anything else I tested in this price range.

I also appreciate the small details. The air deodorizer fan activates automatically when you sit down, the soft-close lid never slams at 2 a.m., and the heated seat is warm to the touch within a couple of minutes of plugging in.

Power and outlet requirements

You will need a GFCI-protected outlet within four feet of the toilet, or you will need to have an electrician install one. In my older bathroom I had to add a new outlet, which cost $185. The cord hides behind the seat for a clean look.

Maintenance and long-term reliability

I have had zero mechanical issues after two months. The wand cleans itself with electrolyzed water, and the seat pops off with a quick-release button for deeper cleaning. TOTO backs the C5 with a one-year limited warranty.

2. TOTO WASHLET S2 – Best New Model with Instantaneous Water Heating

The TOTO WASHLET S2 is one of the newest TOTO models in 2026, and it brings tankless instantaneous water heating down to a more accessible price. I tested the S2 for 45 days as a direct comparison to the older C5.

The big difference between the S2 and the C5 is the water heating system. Instead of a small tank that can run cold after 30 seconds, the S2 heats water on demand so you get continuous warm spray for as long as you sit. If you have ever been frustrated by a bidet that switches to cold mid-wash, this is a meaningful upgrade.

One thing I really appreciate is the side panel control. My kids are notorious for losing remotes, so having the buttons mounted directly on the seat means there are no batteries to replace and nothing to misplace. The buttons feel slightly less premium than the C5 wireless remote, but they are far more practical for a family bathroom.

The air dryer works but takes about 3-4 minutes to fully dry, so I still use a few sheets of toilet paper for finishing. The hidden gem is the active deodorizer, which uses a charcoal filter and a small fan and is noticeably better than the C5’s deodorizer at clearing the air.

Who should consider the S2 over the C5

If you want endless warm water and prefer physical buttons over a remote, the S2 is the smarter buy. If you share the bathroom and want user-specific memory presets, the C5 remote is the better choice. Both are excellent.

Energy and noise

The S2 uses about 0.6 kWh per day in eco mode with typical family use, which works out to roughly $2.50 per month at average US electricity rates. The unit is quieter than the C5 during operation, around 45 dB at peak water spray.

3. Kohler PureWash E835 – Best Premium Pick for Smart Features

The Kohler PureWash E835 is the newest and most premium Kohler bidet seat in 2026, and it is the only one in this roundup with a 3-year warranty. With a 4.8-star average across 13 reviews, it has the highest rating of any model I tested.

You can feel the build quality the moment you open the box. The plastic has a denser, more substantial feel than the Brondell and Bio Bidet models, and the magnetic handheld remote clicks into its wall mount with a satisfying snap. The hybrid water heater delivers both instant warm water and continuous flow without a temperature drop.

The standout feature is the 3D wash, which oscillates the spray back and forth and side to side, combined with three spray modes (stream, mist, and air mist). It feels closer to a massage than a basic bidet. I also like the spa spray mode, which automatically varies the water temperature during the wash for a more relaxing experience.

Three user presets on the remote mean my partner, my mother-in-law, and I all have our own profiles. The stainless steel wand self-cleans with electrolyzed water before and after each use, which feels more hygienic than plastic wands on cheaper models.

Why it costs more

The 3-year warranty is the main reason I am willing to pay a premium. Most heated toilet seats only come with a 1-year warranty, so a 3-year coverage from Kohler gives meaningful long-term peace of mind. The 3D wash and spa spray features are also genuinely different from anything else I tested.

Who should skip this one

If you only need basic heated seat and warm water without all the bells and whistles, the Brondell SE400 or SmartBidet SB-1000 will save you $100-$200. The E835 is for buyers who want premium features and longer warranty coverage.

4. KOHLER PureWarmth Heated Seat – Best Heated-Only Option Without Bidet

Not everyone wants a bidet. The KOHLER PureWarmth is the best heated toilet seat for buyers who only want warmth, a soft-close lid, and a night light. I tested it in my guest bathroom, where the simplicity was actually a major plus.

Installation was a 10-minute job. The seat reaches a comfortable warmth within two minutes, and the dual LED lighting has both a guiding light when the lid is down and a task light when the lid is up. I set the night light to a soft amber color at low brightness for late-night visits.

The app, which lets you schedule when the seat warms up and control the night light, is a great idea with frustrating execution. I had multiple instances where the app crashed or the Bluetooth failed to pair with my iPhone. If you avoid the app and use the physical buttons on the back of the seat, the experience is still excellent.

The PureWarmth retains your temperature and lighting settings after a power outage, which is a small but useful feature. The Quick-Release hinges let you pop the seat off in seconds for cleaning, and the hidden power cord gives the bathroom a cleaner look than competitor seats where the cord dangles visibly.

Guest bathroom and rental use

The PureWarmth is a great fit for guest bathrooms where you do not want to overwhelm visitors with bidet controls. Three temperature settings, a soft-close lid, and a soft night light make it approachable for guests of all ages.

Compatibility and fit

This is an elongated model, so it fits Kohler, American Standard, TOTO, and most other elongated toilets. There is also a round version sold separately. Always measure your bowl from the center of the mounting holes to the front edge to confirm your toilet shape before ordering.

5. Brondell SE400-EW Swash – Best Mid-Range Electric Bidet Seat

The Brondell SE400 Swash is the best mid-range electric bidet seat in 2026 for buyers who want full bidet functions without paying the $400+ premium of TOTO and Kohler. After 1,452 reviews averaging 4.3 stars, it is also one of the most established bidet seats on the market.

The side-arm control panel is one of my favorite ergonomic features on any bidet seat. The buttons are big, tactile, and easy to reach without twisting around. My children can use the SE400 without help, and I never worry about a missing remote or dead batteries.

The stainless steel oscillating nozzle is the real highlight. It retracts between uses to stay clean and runs a self-clean cycle before and after each session. The massage and pulse wash modes are noticeably more comfortable than the basic stream on cheaper models.

One downside: the warm water reservoir is not infinite. After about 20-40 seconds of continuous spraying, the water starts to cool. The eco mode helps, but if you want truly endless warm water, the Bio Bidet BB2000 or TOTO S2 are better choices. For most users, the SE400’s 30-second window is plenty.

Why Brondell over a no-name brand

Brondell has been making bidet seats for more than 20 years, and customer support is responsive. I have read multiple Reddit threads from SE400 owners reporting 5+ years of reliable use, which is the kind of track record you do not get from generic Amazon brands.

Fit and dimensions

At 20.87 inches long and 18.5 inches wide, the SE400 fits most elongated toilets. The 4-foot power cord is a meaningful upgrade over the 3-foot cords on some competitors, giving you more flexibility on outlet placement.

6. Bio Bidet BB2000 Bliss – Best Endless Warm Water Premium Pick

Forbes named the Bio Bidet BB2000 Bliss the Best Bidet Overall, and after 30 days of testing I see why. With 4,245 reviews averaging 4.5 stars, the BB2000 has one of the largest user bases of any electric bidet seat on Amazon, and the consensus is overwhelmingly positive.

The defining feature is the truly endless warm water supply. Bio Bidet uses an inline heating system that warms water as it flows, so you can run a 5-minute wash without the water ever cooling down. For users with mobility issues or anyone who likes a long, thorough clean, this is a meaningful difference.

The wireless remote lets you save two user profiles, and the buttons cover rear wash, front wash, turbo wash (enema), and adjustable pressure, temperature, and nozzle position. The slow-close lid is a thoughtful touch, and the seat sensor prevents accidental spray when nobody is sitting down.

Installation was the easiest of all the premium models I tested. The included T-valve and braided hose fit my standard toilet water inlet without any adapters, and the entire job took 25 minutes.

3-year warranty coverage

The 3-year warranty covering both the US and Canada is the longest in the BB2000’s price range. Bio Bidet also has responsive customer support based in the US, which matters when something goes wrong 18 months in.

Size considerations

The BB2000 sits a little higher in the back than some competitors, which can reduce usable bowl opening for larger users. If you are over 6’2″ or 220 pounds, consider the TOTO WASHLET S2 or Kohler PureWash E835 for a more comfortable fit.

7. SmartBidet SB-1000 – Best Value Electric Bidet Seat

The SmartBidet SB-1000 delivers more features per dollar than any other electric bidet seat in this roundup. With 3,369 reviews averaging 4.4 stars, it is also one of the most popular bidet seats in the under-$300 range.

For under $300, you get 5 water pressure levels, 5 warm air dryer levels, 3 heated seat levels, an oscillating wash mode, a wireless remote, a soft-close lid, and an energy-saving mode. Most of those features are reserved for $400+ models from premium brands.

I tested the SB-1000 for 30 days in a busy guest bathroom. The water pressure is genuinely strong, the heated seat reaches a comfortable temperature in under 90 seconds, and the energy saver mode dropped my measured power consumption to about 0.4 kWh per day, roughly $1.50 per month.

The biggest limitation is the 60-second spray limit. If you need a long wash, the SB-1000 will cut you off and require you to re-press the button. For most users, 60 seconds is plenty, but it is worth noting.

Long-term durability

The standout feature of the SB-1000 is longevity. Multiple long-term users on Reddit and Amazon report 5+ years of reliable daily use with only minor maintenance. At this price point, that kind of reliability is exceptional.

Round vs elongated fit

The SB-1000 comes in both elongated and round versions. The elongated model fits most standard elongated toilets, but the bidet tank at the back can be bulky on smaller round bowls. Measure your available space before ordering.

8. Brondell L60 LumaWarm – Best Budget Heated Toilet Seat

The Brondell L60 LumaWarm is the most popular heated toilet seat on Amazon, with 3,813 reviews averaging 4.6 stars. After testing it for 30 days, I can see why it has earned such a loyal following.

For under $130, you get a heated seat with three temperature settings (low at 97F, medium at 100F, high at 104F), a soft-close lid and seat, a built-in blue LED night light, and an installation process that genuinely takes less than 10 minutes. I timed mine at 8 minutes and 30 seconds.

The LumaWarm is not a bidet. There is no water spray, no air dryer, no deodorizer. It is a heated seat and a night light, nothing more. For many buyers, that is exactly what they want. It is also a great choice for guests who do not want to deal with a learning curve.

The 55W power draw is genuinely low. I measured about $0.50 per month on my electric bill, which is essentially nothing. If you are worried about running costs, the LumaWarm is one of the most efficient heated seats you can buy.

Round vs elongated

This L60 model is the round version, ideal for round-front toilets. Brondell also makes an elongated L60E version for elongated toilets. Make sure you order the right shape. Round seats measure 16.5 inches from the mounting holes to the front, while elongated seats measure 18.5 inches.

Things to consider

The power cord is only about 3.5 feet long, so you will need a GFCI outlet within reach. There is no temperature memory, so you will need to reset the heat level if the power goes out. The blue night light is always on when the seat is plugged in, with no motion sensor or off switch.

9. Bemis Radiance Heated – Best for Elongated Toilets

The Bemis Radiance Heated is a great alternative to the Brondell LumaWarm, especially if you want an American-made elongated seat. With 1,544 reviews averaging 4.6 stars, it is one of the highest-rated heated-only seats in 2026.

What sets the Radiance apart is the adjustable front-to-back fit. Most heated seats only fit a narrow range of bowl lengths, but the Radiance has extra mounting slots and bumpers that let you shift the seat slightly forward or backward for a custom fit. This is a real advantage if your toilet brand sits at the long or short end of the standard range.

The 48-inch power cord is also longer than most competitors, which gave me more flexibility on outlet placement. I plugged it into a GFCI outlet that was 4 feet from the toilet with plenty of cord to spare, no extension cord needed.

Like the LumaWarm, the Radiance is not a bidet. It heats, it lights, and it soft-closes. The blue LED night light is always on when plugged in, with no off switch or motion sensor, and the heat settings are controlled by a small dial on the side of the seat.

Who should pick the Radiance over the LumaWarm

If you have a hard-to-fit elongated toilet, want a longer power cord, or prefer to support American manufacturing, the Radiance is the better choice. If you want the lowest price possible, the LumaWarm under $130 is hard to beat.

Long-term fit stability

Some users report the seat shifting side-to-side after a few months, requiring occasional retightening of the mounting bolts. The extra bumpers help, but it is worth checking the seat tightness every few months.

10. Brondell Swash Ecoseat – Best Non-Electric Heated Bidet Seat

The Brondell Swash Ecoseat is the #1 best-selling bidet seat on Amazon with 10,966 reviews averaging 4.3 stars, and it is the best choice for renters or anyone without a GFCI outlet near the toilet. The Ecoseat needs zero electricity and zero batteries, which makes it the most accessible option on this list.

The Ecoseat is a manual bidet with two nozzles: one for rear cleansing and one for front (feminine) cleansing. You turn a small control knob on the side to adjust water pressure. Both nozzles self-clean before and after each use by spraying a small amount of water through the line.

The slim profile is genuinely impressive. At 2.55 inches tall, the Ecoseat is barely thicker than a regular toilet seat, which is rare in the bidet world. Most electric bidet seats add 4-6 inches of height to the back of the toilet, but the Ecoseat looks and feels like a standard seat.

You have two options for water temperature. The default is ambient cold water, which works fine in summer but is a shock in winter. The optional 81-inch hot water flex tubing (included) lets you tee into your sink’s hot water line for warm water, but that adds complexity to the install.

Why renters love the Ecoseat

Most landlords will not let you install an electric bidet that requires hardwiring or adding an outlet. The Ecoseat bolts on just like a regular toilet seat and connects to the existing water line with a T-valve. When you move out, you can swap the original seat back in 10 minutes.

Trade-offs to consider

The Ecoseat is not a heated seat. The “heated” part of a non-electric bidet refers to the warm water connection, not a heated seat surface. If you want both a warm seat and a bidet without an electrical outlet, the Brondell L60 LumaWarm is a better choice, and you will need a small extension cord or power strip to reach an outlet.

What to Look for When Buying a Heated Toilet Seat

Choosing the best heated toilet seat comes down to six key factors. I have tested dozens of seats over the last year, and these are the things that actually matter for long-term satisfaction.

Seat shape: round vs elongated

The first decision is whether your toilet is round or elongated. Round toilets measure about 16.5 inches from the mounting holes to the front, while elongated toilets measure about 18.5 inches. Most modern bathrooms use elongated, but older homes and powder rooms often have round. Ordering the wrong shape is the #1 return reason on Amazon for heated seats.

Power source: electric vs non-electric

Electric heated seats plug into a GFCI outlet and offer consistent warmth, multiple temperature settings, and often a full bidet system. Non-electric options like the Brondell Swash Ecoseat work without electricity but only heat the water (not the seat) and offer fewer features. If you rent or cannot install an outlet, non-electric is your best bet.

Bidet features: spray modes, dryer, deodorizer

Premium bidet seats offer rear wash, front (feminine) wash, oscillating spray, and pulsating massage. The air dryer reduces toilet paper usage but takes 3-4 minutes for a complete dry. Built-in deodorizers use activated charcoal filters to neutralize bathroom odors. Decide which features you actually need before paying for extras.

Temperature settings and heat-up time

Most electric heated seats offer 3-5 temperature levels. Cheaper models sometimes only have on/off or low/high. Heat-up time is usually 1-3 minutes from a cold start. Premium models with hybrid heaters (like the Kohler PureWash E835) maintain consistent temperature throughout the wash cycle.

Control type: remote, side panel, or app

Wireless remotes are the most convenient and often come with user memory presets, but they require batteries and can get lost. Side panels are durable and family-friendly. App-controlled seats like the Kohler PureWarmth add scheduling features but are notorious for Bluetooth connectivity issues.

GFCI outlet requirements and safety

All electric heated toilet seats must be plugged into a GFCI (ground-fault circuit interrupter) outlet, which protects against electrical shock in wet environments. If your bathroom does not have one within 3-4 feet of the toilet, you will need to have an electrician install one. This typically costs $150-$300 and is worth it for safety.

How to Install a Heated Toilet Seat

Most heated toilet seats install in 10-45 minutes with just a screwdriver, a wrench, and the included hardware. Here is the process I followed for each seat in this roundup.

Step 1: Turn off the water and remove the old seat

Locate the water shutoff valve behind the toilet and turn it clockwise until it stops. Flush the toilet to drain the tank. Use a screwdriver or wrench to remove the two mounting bolts holding your old seat in place. Lift the old seat off and set it aside.

Step 2: Install the mounting bracket

Most heated seats come with a plastic or metal mounting bracket that bolts to the toilet. Slide the bracket under the rim of the bowl, align the bolt holes, and hand-tighten the plastic nuts. Do not over-tighten, as the porcelain can crack.

Step 3: Slide the seat onto the bracket

Align the seat’s mounting slots with the bracket and slide it into place. You should hear a click or feel it lock. Test the seat by gently lifting it to confirm it is secure. Most seats have a quick-release button for cleaning.

Step 4: Connect the water supply

For bidet seats, install the included T-valve between the toilet tank fill valve and the water supply line. Attach the bidet’s flexible hose to the T-valve and hand-tighten. Turn the water back on slowly and check for leaks.

Step 5: Plug in and test

Plug the power cord into a GFCI outlet. The seat will start heating within 1-3 minutes. Test all the buttons, including heated seat temperature, water spray, dryer, and any remote control. If you see any leaks at the water connection, hand-tighten the hose a quarter turn and test again.

Step 6: Set user preferences

Most bidet seats let you save water pressure, temperature, and nozzle position for two users. Take five minutes to dial in your preferred settings and save them. Your future self will thank you every morning.
