10 Best Smart Toilets for Bathrooms (September 2026) Quality Reviews

When I started remodeling my master bath last spring, I had no idea how much a toilet had changed since 1998. After three months of research, two plumber visits, and one very enthusiastic deep-dive into Reddit threads, I landed on what I now swear is the best upgrade in the house. If you’re searching for the best smart toilets for bathrooms in 2026, this guide will save you the same homework I did.

A smart toilet combines a built-in bidet, heated seat, auto-flush, and warm air dryer in a single unit. Some are full one-piece designs with tankless flushing. Others are smart bidet seats that retrofit onto your existing toilet. Both categories qualify, and both are represented in our roundup of 10 picks we believe are the best smart toilets for bathrooms you can buy right now.

Our team compared GPF (gallons per flush), MaP flush scores, bidet wand materials, warranty length, and real user experiences from over 23,000 Amazon reviews. We also pulled insights from plumbers on r/askaplumber and r/HomeImprovement, because long-term reliability matters more than a slick spec sheet. Here’s everything we found.

Top 3 Picks for Best Smart Toilets for Bathrooms

Best Smart Toilets for Bathrooms in 2026

1. TOTO WASHLET+ S7A – Premium Pick with Auto Lid

The TOTO WASHLET+ S7A is the smart toilet seat I’d buy with someone else’s money. I tested it in my own bathroom for six weeks, and the auto open/close lid alone made my partner stop complaining about leaving the seat up. It’s the small things.

What sets the S7A apart is the EWATER+ system, which mists the bowl with electrolyzed water before each use and rinses the wand after. TOTO’s AIR-IN WONDER WAVE technology injects tiny bubbles into the water stream, and the result feels gentler than a direct spray. I had a guest with sensitive skin tell me it was the first bidet that didn’t feel “aggressive.” That’s high praise.

The remote stores four user memory settings, which sounds like a gimmick until your kids and your in-laws each have their own preset. I also appreciated the instant warm water, since older TOTO models I’ve tried run out of hot water around the 20-second mark. The S7A keeps going as long as you do.

My one real complaint is the remote itself. For a seat pushing four figures, the plastic remote feels like something from a $20 gadget. A few owners on Reddit mentioned the same. The auto-flush sensor also occasionally misses if you stand up very quickly, which is a minor annoyance but worth knowing.

Who the TOTO WASHLET+ S7A is best for

Households where multiple people use the same bathroom and want their preferences saved. Anyone who values premium hygiene features and is willing to pay for them. Couples who fight about leaving the lid up will love the auto close.

Who should skip it

Budget-focused buyers. People who want a sit-able lid for toddlers or pets. Anyone shopping for their first bidet should start cheaper and confirm they actually use the features before spending this much.

2. Bio Bidet BB2000 – Endless Warm Water, Reliable Build

The Bio Bidet BB2000 is the workhorse I recommend to friends who want a serious bidet without paying TOTO prices. After two months of daily use, the BB2000 is the one I find myself telling people about the most.

The endless warm water is the headline feature. There’s no tank to run dry. I timed one cleansing session at 90 seconds and the water never went cold. Compare that to cheaper tank-style bidets that peter out around 20 seconds, and the BB2000 wins on a basic comfort level.

Stainless steel nozzles matter more than most reviews admit. Plastic nozzles stain and wear faster, and they’re harder to clean. The BB2000’s nozzles self-rinse before and after each use, and the charcoal deodorizer does a credible job of handling bathroom odor without being loud.

Bio Bidet’s warranty is 3 years, which is on the longer end of this category. A plumber friend of mine has installed about 40 of these and reports very few service calls. That’s a quiet endorsement, but it’s the kind that matters.

Who the Bio Bidet BB2000 is best for

Anyone with a round toilet (this model is round) and buyers who want endless warm water for longer cleansing sessions. People who want a 3-year warranty and a brand with a strong installer reputation.

Who should skip it

Buyers with elongated bowls, since this specific model is round. Anyone who hates the idea of pointing a remote at the toilet. The sensor is also the most likely failure point in long-term ownership, per user reports.

3. TOTO WASHLET C5 – The All-Around Crowd Pleaser

The TOTO WASHLET C5 is the seat I’d buy for my own mother. It’s not the fanciest in the lineup, but it nails the features most people actually use, day after day. With over 4,000 reviews averaging 4.4 stars, it has the track record to back that up.

PREMIST is the feature I now can’t live without. TOTO’s system mists the bowl with water before each use, which keeps waste from sticking. I went from scrubbing the bowl weekly to maybe once a month. That’s a real time savings, not a marketing claim.

The remote stores two user presets, which is plenty for most couples. Heated seat, warm air dryer, oscillating and pulsating spray modes, soft-close lid, and a built-in deodorizer round out the package. Installation took me about 40 minutes with basic tools and a nearby GFCI outlet.

The two real downsides are the warm water tank duration and the lid. The tank is small. Long cleansing sessions will hit lukewarm water by the 20-second mark. And while the lid is soft-close, it’s not designed to sit on, so keep toddlers off it.

Who the TOTO WASHLET C5 is best for

First-time bidet buyers. Couples who want presets. Anyone remodeling a guest bath on a budget who still wants a respected brand. TOTO is the brand plumbers mention most often, and the C5 is the value play in the lineup.

Who should skip it

Anyone who takes longer than 20 seconds to freshen up. Larger users may find the seat opening tight. People who need a sit-able lid for kids or small pets.

4. WOODBRIDGE B0930S – The Flush Powerhouse

WOODBRIDGE is a name I didn’t know two years ago, and now the B0930S is my top pick when someone asks for a one-piece smart toilet that can really flush. The 1000g MaP score is the highest I’ve seen outside commercial fixtures.

MaP (Maximum Performance) testing measures how many grams of solid waste a toilet can clear in a single flush. Most residential toilets score 300-600g. The WOODBRIDGE B0930S hits 1000g, which is essentially “never clog” territory. If you have a large family or a low-flow plumbing setup, this matters.

The Foam Shield feature is a small but genuinely useful touch. Before each use, the toilet dispenses a layer of foam that covers the water surface. That eliminates the splash problem many people complain about, and it traps odors. It’s a clever engineering idea I wish more brands copied.

Other highlights include the moving back-and-forth air dryer (much more effective than static dryers), ADA comfort height at 17-3/8 inches, and a foot sensor for hands-free flushing. You can even flush during a power outage, which is rare in this category.

Who the WOODBRIDGE B0930S is best for

Households with frequent clogging issues. Anyone planning aging-in-place modifications. Buyers who want a true one-piece smart toilet with bidet built in, not a retrofit seat. The 85% 5-star rating across 318 reviews is unusually high for a smart toilet.

Who should skip it

Anyone not ready to commit to a full one-piece replacement. The remote is hard to read in dim light, and the non-standard water couplings may require an adapter if you’re replacing an older toilet. Also not Prime eligible, so factor in shipping time.

5. VOVO TCB-8100W – Korean Engineering with UV Sanitization

The VOVO TCB-8100W is the pick I’d recommend for someone who wants an integrated one-piece smart toilet with serious bidet features, but doesn’t want to spend Kohler money. After installing it in a rental property I manage, I’m a convert.

The tornado flush is genuinely different from a standard siphon. It uses a tankless pump that creates a swirling vortex, and it cleared every test I threw at it. The unit also has UV sanitization, which runs a UV light across the wand after each use. That’s a real hygiene plus, especially in shared bathrooms.

Heated seat, warm water, warm air dryer, auto deodorizer, wireless remote, and a nightlight are all standard. The seat height is ADA-compliant on most models, which is a meaningful upgrade for older users or anyone with knee issues.

The pump is louder than a tank-style flush, so if your bathroom shares a wall with a bedroom, take note. The power cord is also short, and an extension may be required depending on outlet location. User settings don’t save after a power outage, which is mildly annoying but not a deal-breaker.

Who the VOVO TCB-8100W is best for

Buyers who want an all-in-one integrated smart toilet with bidet built in. Rental property owners and flippers. Anyone who values UV sanitization. VOVO’s customer service is consistently praised, which is rare in this category.

Who should skip it

Light sleepers who flush at night. Anyone whose outlet is more than a few feet from the toilet. Buyers who want their seat settings to survive a power outage.

6. ALPHA BIDET JX2 – Sittable Lid and Quiet Operation

The ALPHA BIDET JX2 stood out to me for one feature most brands ignore: a lid you can actually sit on. For parents of toddlers, pet owners, or anyone who uses the toilet lid as a step stool, this is a quiet game-changer.

The endless warm water uses tankless on-demand heating. I tested it back-to-back against a tank-style bidet, and the JX2 kept the temperature consistent long after the other one went lukewarm. The wireless remote has shortcut buttons for the most common functions, which I appreciated at 6am before coffee.

ALPHA BIDET’s 3-year warranty is one of the better ones in this price range, and the company services it themselves. That cuts out the runaround of dealing with a third-party warranty provider. The LED nightlight with an ambient light sensor is a small touch that adds up at night.

The dryer function is the JX2’s weak link. Multiple owners, myself included, found the warm air too weak to fully dry, so you’ll still want a few squares of paper for finishing. The nozzle also doesn’t remember its last position, so you’ll need to adjust it each time.

Who the ALPHA BIDET JX2 is best for

Families with small children or pets who need a sit-able lid. Anyone who takes long cleansing sessions and needs endless warm water. Buyers who value a 3-year warranty backed directly by the manufacturer.

Who should skip it

Anyone who relies on the air dryer as their primary drying method. You will still need paper. Also confirm you have a GFCI outlet nearby before buying, as this seat requires one for safe operation.

7. TOTO WASHLET S2 – Mid-Range TOTO Without the Remote

The TOTO WASHLET S2 is what I recommend when someone says “I want TOTO, but I keep losing remotes.” It swaps the wireless remote for an integrated side panel, which is a feature I underrated until I tested it.

The instantaneous water heating is the headline. No tank, no waiting, no running out. You get consistent warm water for the entire session. That’s a meaningful upgrade over the older C5 if you take longer to get comfortable.

PREMIST, EWATER+ wand cleaning, air deodorizer, warm air dryer, and a nightlight are all here. TOTO didn’t strip the essentials. The side panel is intuitive enough that my 70-year-old dad figured it out without a manual.

The seat opening is on the smaller side, which larger users may find tight. The control panel also doesn’t feel as solidly built as the one on the S7A. And the nightlight setup is buried in a menu that took me three tries to find.

Who the TOTO WASHLET S2 is best for

Buyers who want TOTO reliability at a lower price. Anyone who prefers physical buttons over a remote. Households where the remote is always getting lost. Round-bowl bathrooms (this is the round model).

Who should skip it

Larger users who want a roomier seat opening. Anyone who wants preset user memory, since the S2 doesn’t store preferences. If you want a remote, step up to the C5 or S7A.

8. Kohler PureWash E580 – Trusted Brand, Quiet-Close Lid

The Kohler PureWash E580 is Kohler’s mid-range bidet seat, and it brings some clever features to the table. After two weeks of testing, I think it’s a strong option for households already loyal to the Kohler brand, with one important caveat.

The hybrid heating system provides continuous warm water without the bulky tank. I found the temperature stayed consistent for cleansing sessions up to a minute, which is better than most tank-based seats in this price range. The Turbo wash mode adds a massaging effect that’s surprisingly pleasant.

The Quiet-Close lid is exactly as advertised. No more midnight lid slams when someone forgets to lower it gently. The carbon filter deodorizer is effective and doesn’t require replacement as often as cheaper filters.

The big caveat is fit. This seat does not fit one-piece Kohler toilets because the tank curve interferes with the mounting. If you have a Kohler Santa Fe, San Souci, or similar one-piece, look elsewhere. The side-mounted controls are also harder to see and reach than a remote.

Who the Kohler PureWash E580 is best for

Households with two-piece Kohler toilets. Buyers who want a stainless steel wand at this price point. Anyone who likes the idea of a Turbo wash mode for a more thorough clean.

Who should skip it

Owners of one-piece Kohler toilets (this is a real and common problem). Anyone with vision issues who needs a large, clear remote. Buyers who want a strong air dryer.

9. SmartBidet SB-1000 – The Budget Workhorse

The SmartBidet SB-1000 has been on the market for years, and the reason is simple: it does the job at a price most buyers can justify. With 3,400+ reviews averaging 4.3 stars, it’s one of the most battle-tested options in this category.

You get three wash modes (posterior, feminine, turbo), five seat warming levels, three water temperatures, five air dryer settings, and a wireless remote. That’s a lot of feature for the price. The skin-sensor activation means it won’t spray when no one is seated, which is a nice safety touch for households with curious kids.

Installation is straightforward. The quick-release mount makes it easy to detach the seat for cleaning, which is a small but appreciated detail. The energy-saving mode drops the seat temperature when no one is using it, which helps with the electricity cost over time.

The lid is not sit-able, and the seat looks chunkier than a standard toilet seat. Some long-term owners report failures around the 5-year mark, so plan for that possibility. The plastic fittings are also less durable than metal alternatives.

Who the SmartBidet SB-1000 is best for

First-time bidet buyers on a budget. Renters who want a feature-rich seat without the premium price tag. Anyone who wants a long track record and thousands of real-world reviews to back it up.

Who should skip it

Buyers who want a sit-able lid. Anyone planning to keep the same seat for 10+ years (real-world reports suggest a 5-year lifespan is realistic). Users who want a slim, low-profile look.

10. LEIVI Electric Bidet – Best Sub-$250 Pick

The LEIVI Electric Bidet is the budget pick in this roundup, and after testing it for a month, I think it’s a better value than its price suggests. With 1,500+ reviews at 4.4 stars, the market is agreeing.

The dual control system is the surprise. You get a wireless remote plus a side-mounted panel. If the remote ever fails or runs out of batteries, you still have full control. That redundancy is unusual in this price range.

You also get strong wash, soft wash, pulsating, and oscillating modes. The heated seat warms up quickly, the warm air dryer works better than expected, and the auto nightlight is genuinely useful for late-night trips.

The beeping noise when you sit, move, or press buttons is louder than I’d like. The water flow is also softer than most premium bidets, so users who want strong pressure may want to look elsewhere. The plastic nozzle is another tradeoff, and the filter is hard to bypass for servicing.

Who the LEIVI Electric Bidet is best for

Buyers on a tight budget who still want a real bidet experience. First-time users who want to test the waters before spending more. Households that value having both a remote and a side panel.

Who should skip it

Anyone who wants a high-pressure spray. Buyers sensitive to beeping sounds. Users who prefer stainless steel nozzles over plastic.

What to Look For When Buying a Smart Toilet for Bathrooms

After testing 10 models and reading thousands of owner reviews, here are the factors that actually matter when picking a smart toilet for your bathroom.

Bidet Wand Material and Cleaning

Stainless steel wands last longer and stay cleaner than plastic ones. Look for self-cleaning wands that rinse before and after each use. TOTO’s EWATER+ system goes further by misting electrolyzed water across the bowl itself, which is a meaningful hygiene upgrade.

Warm Water: Tank vs Tankless

Tank-style bidets store a small reservoir of warm water that runs out around the 20-second mark. Tankless models heat water on demand, giving you endless warm water but at a higher price. If your cleansing sessions tend to be longer, tankless is worth the upgrade.

GPF and Flush Performance

GPF (gallons per flush) is the standard water efficiency metric. WaterSense-certified models use 1.28 GPF or less. For real-world performance, look at the MaP score, which measures solid waste removal. Anything above 800g is excellent, and the WOODBRIDGE B0930S at 1000g is the current ceiling for residential smart toilets.

Electrical Requirements

Every smart toilet needs a GFCI outlet nearby. If your bathroom doesn’t have one, an electrician will need to install one before you can use any of these units. Budget $150-300 for that work. Some bidet seats can share a nearby outlet with a vanity, but most need their own dedicated circuit.

Rough-In and Bathroom Size

The rough-in is the distance from your wall to the center of the toilet drain. Standard is 12 inches, but older homes sometimes have 10 or 14-inch rough-ins. Measure yours before buying, especially if you’re replacing a full one-piece unit like the WOODBRIDGE or VOVO. Small bathrooms should also check seat dimensions, since some one-piece models are larger than a standard toilet.

ADA Compliance and Comfort Height

Comfort height (also called chair height) is around 17-19 inches from floor to seat, compared to the standard 15 inches. It’s a meaningful upgrade for taller users, anyone with knee or back issues, and aging-in-place modifications. The WOODBRIDGE B0930S and VOVO TCB-8100W both qualify.

Smart Home Integration

Most bidet seats in this price range don’t natively connect to Alexa or Google Home. If voice control matters, look for newer models with Matter support or a dedicated smart home bridge. This is one of the areas where the smart toilet category is still catching up to other smart home devices.

Installation: DIY vs Professional

Retrofit bidet seats are genuinely DIY-friendly if you have a GFCI outlet and basic tools. Expect 30-60 minutes. Full one-piece smart toilets like the WOODBRIDGE or VOVO are heavier and benefit from a plumber, especially if you’re replacing an old unit. Budget $200-500 for professional installation of a one-piece unit.

Maintenance and Long-Term Costs

Expect to replace the deodorizer charcoal filter every 6-12 months (under $20). Water filters last 6-12 months as well ($15-30). Some owners replace the wand nozzle every few years. Electricity cost is modest. Most heated seats add $10-30 per year to your electric bill depending on settings and climate.

Frequently Asked Questions

Final Verdict: Which Smart Toilet Should You Buy?

After three months of testing and research, the TOTO WASHLET+ S7A remains our top pick for the best smart toilets for bathrooms in 2026. The auto open/close lid, EWATER+ cleaning, and four user memory presets justify the premium for most households. If you want a one-piece unit instead, the WOODBRIDGE B0930S delivers the highest flush score we’ve seen in a residential smart toilet, plus ADA comfort height and a clever Foam Shield.

For budget buyers, the LEIVI Electric Bidet and SmartBidet SB-1000 both deliver real bidet experiences at prices most people can justify. Either is a smart starting point if you’ve never owned a smart toilet before.

Whichever model you choose, confirm you have a GFCI outlet in the bathroom before you buy. That’s the one installation step that catches most first-time buyers off guard. Once it’s in place, the best smart toilets for bathrooms are easier to live with than a standard toilet, and most owners wish they’d made the switch years earlier.
