TOTO WASHLET S5 Review: Honest Pros & Cons Worth Buying?

Most TOTO WASHLET S5 review,TOTO WASHLET S5 review and rating,is TOTO WASHLET S5 worth buying,TOTO WASHLET S5 review pros cons,TOTO WASHLET S5 review honest opinion,TOTO WASHLET S5 review verdict guides start with sterile spec lists, but let me begin with my bathroom reality. After years of using a cheap cold-water bidet attachment that delivered inconsistent pressure and left me shivering during winter mornings, I finally decided to invest in a proper premium electric bidet seat. The breaking point was when my toddler attempted to use the “sprayer” and accidentally soaked the bathroom wall. I needed something integrated, safe, and genuinely effective. My research shortlist came down to three main contenders: the TOTO WASHLET S5, the BioBidet BB-2000, and the Kohler Novita BH90. I landed on the S5 primarily because of its PREMIST bowl-wetting technology and the EWATER+ self-cleaning wand system, which promised a level of hygiene that the others did not explicitly offer. After spending over a month living with the S5, this is my complete, honest account of what it is actually like to own one.

What I Knew Before Buying

What the Product Claims to Do

TOTO markets the S5 as a ecology-minded luxury seat. The primary claims are instantaneous warm water cleansing, the PREMIST system (which uses supply water to wet the bowl before use to help waste slide away), and the EWATER+ system (which uses electrolyzed water to clean the wand inside and out). It also boasts a heated seat with five temperature settings, an air deodorizer, a warm air dryer, and a soft-close lid. The marketing language is confident, specifically about the TOTO USA website claiming it offers “a refreshing clean for everyone.” What sounded vague before buying was the “pulsating and oscillating option” — I wondered if it was just a marketing gimmick for a variable nozzle.

What Other Reviewers Were Saying

The general consensus I found online was overwhelmingly positive, reflected in its 4.6-star rating on Amazon across 276 reviews. Most users praised the instant hot water and the build quality. The consistent complaint I noticed involved the price, with several people noting that it is an expensive seat compared to other brands like BioBidet or AlphaBath. Some users also mentioned that the seat size is better suited for standard to medium body frames and may feel narrow for larger users. This conflicting opinion on fit gave me pause, but I decided to proceed because my household falls into the average size range.

Why I Still Decided to Buy It

My decision came down to three non-negotiable needs. First, I needed instantaneous water heating; my old tank-based bidet ran out of hot water after 30 seconds. This **TOTO WASHLET S5 review and rating** phase confirmed that the S5 uses a 1300W heater that provides endless hot water. Second, the PREMIST feature was uniquely appealing. I hate scrubbing the toilet, and the idea of a automated bowl wetting to prevent waste from sticking was a compelling hygiene benefit I couldn’t find in the same capacity from the other contenders. Third, I trusted TOTO’s long-term reliability. The brand is synonymous with quality plumbing fixtures globally, and this seat felt like a genuine engineering investment rather than a cheap gadget. While I considered the “is TOTO WASHLET S5 worth buying” question heavily, the combination of these three specific factors—instant heat, automated bowl care, and brand reputation—pushed me over the edge.

What Arrived and First Impressions

What Came in the Box

The package included the main S5 bidet seat unit, a mounting plate with hardware, a stainless steel flex hose, a T-valve adapter, a large wireless remote with a wall-mount bracket, four AA batteries for the remote, and an installation manual. I was pleased to find the Sedona Beige color matched my older TOTO Drake toilet almost perfectly. Nothing was missing, though I was slightly surprised that the unit did not come with a water filter, which some competitors include in the box. The packaging itself was dense, high-quality foam that kept the unit secure.

Build Quality Gut Check

Picking up the seat, the first thing I noticed was its weight—15.4 pounds. It feels substantial. The plastic shell is thick and has a smooth, matte finish that resists fingerprints. The seat hinge mechanism is a heavy-duty metal component that inspires confidence; it does not wobble. Compared to the $200 bidet seat I had before, this feels like a true appliance. One specific detail that stood out was the smooth, almost silent motion of the wand as I manually extended it during inspection — the motorized gears are clearly well-engineered. The wireless remote, however, feels a bit hollow and plastic-y compared to the solidity of the seat itself.

The Moment I Was Pleasantly Surprised or Disappointed

I was pleasantly surprised by the low profile of the S5. When closed, the seat sits very flush against the toilet bowl, giving a sleek, contemporary look. The illuminated night light is a soft blue glow that is bright enough to guide you in the dark but not so bright that it is annoying. I was slightly disappointed by the remote’s construction; considering the premium price of a **TOTO WASHLET S5 review pros cons** analysis, I had hoped for a metal or softer-touch plastic finish. It works perfectly, but it lacks the same tactile luxury as the seat itself.

The Setup Experience

Time from Box to Ready

From opening the box to having a functional seat took me exactly 47 minutes. The vast majority of that time was spent removing my old toilet seat and cleaning the bowl area. The actual mounting process is straightforward: slide the mounting plate onto the toilet bolts, tighten, click the seat into place, and connect the water supply lines. The included T-valve adapter made connecting the bidet hose to my existing water supply line simple. Included documentation is clear with diagrams, though the text is small.

The One Thing That Tripped Me Up

The one thing that tripped me up was ensuring the water hose connection to the seat was fully engaged. The hose uses a quick-connect push-fit system. I pushed it in, heard a click, but it was not fully seated. When I turned the water supply back on, it created a slow, annoying drip behind the unit. I had to disconnect, push much harder than expected, and twist slightly to lock it in place. This took an extra 15 minutes of troubleshooting and drying up water. My advice for new buyers is to push the hose connector into the base of the seat with significant force until you are absolutely sure it has clicked into the locking groove.

What I Wish I Had Known Before Starting

Here are a few things I wish I had known before starting the installation: 1. Have a towel ready underneath the entire installation area. There is always residual water in the toilet tank and supply line. 2. Install the batteries in the remote and pair it to the seat *before* mounting the seat to the toilet. It is easier to access the pairing button when the unit is not mounted. 3. The remote wall mount is adhesive-backed. Make sure your bathroom wall tiles are clean and dry, and place the mount exactly where you want it. Removing it is a challenge and may damage paint. 4. Attach the T-valve to the water supply line first, flush the toilet to clear any debris, and *then* connect the bidet hose. This avoids clogs in the internal filter.

Living With It: Week-by-Week Observations

Week One — The Honeymoon Period

The first week was pure fascination. The instant hot water is a genuine game-changer. There is no lag—as soon as the spray starts, the water is warm. The oscillating posterior wash is incredibly thorough and comfortable. The heated seat on level 3 is perfect for a chilly bathroom. I found myself using the “front cleanse” mode just to test the consistency. By the end of week one, I was already convinced that the “is TOTO WASHLET S5 worth buying” question was leaning heavily towards “yes.” The PREMIST function is subtle: you hear a brief hiss when you sit down or trigger the sensor, wetting the bowl.

Week Two — Reality Check

After two weeks of daily use, the novelty wore off, and I started noticing the small annoyances. The air dryer is effective but slow. It takes about 2-3 minutes to fully dry, which is standard for bidets, but I stopped relying on it exclusively and started using a small towel to finish the job. The seat heater on level 5 is genuinely too hot for comfortable long-term sitting; I keep it at level 3. I also noticed that the remote, while intuitive, has many buttons. It took my partner a few days to stop accidentally pressing the “stop” button instead of the “rear cleanse” button. The deodorizer works extremely well—silent and effective at neutralizing odors almost instantly.

Week Three and Beyond — Long-Term Verdict

At the three-week mark, my overall impression solidified. This is not just a bathroom gadget; it is a fixture that changes your daily comfort baseline. What I undervalued during research was the **TOTO WASHLET S5 review honest opinion** of the EWATER+ system. It gives immense peace of mind. The wand is pristine every morning, with no hard water stains or visible residue. The PREMIST technology has genuinely kept my toilet bowl cleaner for longer. I have only had to scrub once in five weeks, compared to weekly cleaning. My overall assessment improved from week one to week three because I realized the value lies not in the “fun” of using it, but in the reduction of maintenance and the consistent comfort. It simply works quietly and effectively.

What the Spec Sheet Does Not Tell You

The Noise Level

The EWATER+ activation is audible. It is not loud, but it produces a distinct humming/buzzing sound for about 30 seconds after each use as it generates electrolyzed water. At night, this sound is noticeable in a quiet bathroom. The spray itself, however, is much quieter than standard nozzles I have used. The PREMIST hiss is also very soft.

Spray Pattern Variations

What the product page does not mention is how much the “soft rear” spray differs from the “rear cleanse.” The soft spray is a wide, gentle rain shower pattern, perfect for sensitive days or general freshening. The rear cleanse is a focused, powerful stream. It took me a week to find the right setting for each need. The oscillating feature moves the nozzle back and forth, which is excellent for thorough cleaning.

The Seat Position Sensor

I would have expected the seat to turn on the moment I sat down, but the sensor has a slight delay (about 1 second). This is intentional to ensure the user is fully seated. The control panel on the remote locks when you are not seated, so you cannot accidentally spray water while standing up, which is a very thoughtful safety feature.

Wand Maintenance

While EWATER+ cleans the wand components effectively, the plastic nozzle tips can still accumulate visible dust over a week. I found that about once a month, I need to manually wipe the tips with a cloth. The wand itself slides in and out with zero wobble, which is a testament to TOTO’s engineering precision.

Power Draw in Standby

I measured the power draw using a plug-in monitor. In standby mode (seat heat on, deodorizer standby, PREMIST armed), it draws about 8-12 watts. When heating water, it briefly spikes to around 1300 watts. This translates to roughly $2-3 per month in electricity costs, which is negligible.

Competitor Advantage

Compared to my previous experience with the BioBidet BB-2000, the TOTO S5 is missing a physical knob on the unit itself. If you lose the remote or the batteries die, you cannot operate the wash features at all. The BB-2000 has tactile side controls as a backup. This is a genuine oversight in the S5’s design.

The Honest Scorecard

Category	Score	One-Line Verdict
Build Quality	9/10	Excellent materials and fit, feels built to last for a decade.
Ease of Use	8/10	Remote is intuitive, but the sensor delay and numerous buttons take adjustment.
Performance	9/10	Instant hot water and superior cleaning consistency.
Value for Money	7/10	Expensive upfront, but justified by TOTO engineering and low maintenance.
Durability	9/10	Robust hinge, reliable electronics, and resistant to hard water stains.
Overall	8.5/10	A luxury essential that performs exactly as described with minor quirks.

**Build Quality (9/10):** The seat is robust, the hinge is smooth and heavy-duty, and the plastic is high-grade. The Sedona Beige color matches perfectly. The only deduction is the slightly cheap feel of the remote compared to the main unit. **Ease of Use (8/10):** The wireless remote is logically laid out, with clear icons for Rear Cleanse, Front Cleanse, and Dry. However, it has a lot of buttons, and the learning curve for new users is a few days. The sensor that disables the controls when standing is a great safety feature. Night light is a nice touch. **Performance (9/10):** The instant water heater is flawless. The oscillating and pulsating wash modes are genuinely effective and not gimmicks. PREMIST and EWATER+ deliver on their promises, resulting in a cleaner bowl and a self-sanitizing wand. Air dryer works but is slow. **Value for Money (7/10):** At $780, this is firmly in the premium bidet seat category. You can find comparable features (heated seat, dryer) for $400-$500. The premium you pay is for the PREMIST, EWATER+, and TOTO reliability. If these specific hygiene features matter to you, it is worth it. If not, you are overpaying. **Durability (9/10):** After 5 weeks, everything works as new. I have no concerns about longevity. TOTO has a strong track record. The EWATER+ system also helps protect the wand from mineral buildup, which is a common failure point in other bidets.

How It Stacks Up Against the Alternatives

The Shortlist I Was Choosing Between

Before settling on the S5, I had a serious shortlist of three premium bidet seats: the BioBidet BB-2000 (for its seat size and side controls), the Kohler Novita BH90 (for its sleek design and integrated warm water), and the TOTO WASHLET S5. Each had unique selling points.

Feature and Price Comparison

Product	Price	Best Feature	Biggest Weakness	Best For
TOTO WASHLET S5	$780	PREMIST + EWATER+	High price, no side controls	Hygiene focused buyers
BioBidet BB-2000	$550	Larger seat, side controls	No PREMIST, bulkier design	Larger users, value seekers
Kohler Novita BH90	$700	Sleek design, Kohler warranty	Less effective bowl mist	Design and brand loyalists

Where This Product Wins

This product wins in the hygiene category. If you are a meticulous cleaner or hate scrubbing the toilet, the PREMIST and EWATER+ combination is superior to anything else in this price range. It also fits TOTO toilets perfectly; the Sedona Beige color is a near match for their standard cotton white and Sedona Beige bowls. The memory settings for 4 users are excellent for families.

Where I Would Buy Something Else

If you have a larger physique, the BioBidet BB-2000 has a notably wider, more contoured seat. If you are on a tighter budget but still want instant hot water, the BB-2000 offers a similar experience for $200 less. If you want a fully integrated smart toilet (one piece), consider reading our review of the Royalbath Smart Toilet which is a complete unit rather than a seat.

The People This Is Right For (and Wrong For)

You Will Love This If…

– You own a TOTO toilet. The fit and color matching is OEM-level. – You are a family with multiple users. The 4 presets allow everyone to save their preferred seat temperature, water pressure, and spray position. – You prioritize hygiene and hate cleaning toilets. The PREMIST and EWATER+ will significantly reduce your maintenance routine. – You live in a colder climate. The heated seat and instant warm water are fantastic comforts during winter. – You need a high-quality, reliable appliance. The build quality and TOTO warranty give peace of mind.

You Should Look Elsewhere If…

– You are on a strict budget of under $500. The TOTO WASHLET S5 review might frustrate you if you cannot justify the premium. – You have a round toilet. This seat is elongated only and will overhang. – You prefer physical controls on the unit itself. If you do not want to rely on a remote, look at the BioBidet BB-2000 which features side-mount controls.

Things I Would Do Differently

What I would check before buying

I would measure the distance between my toilet mounting bolts and the bowl more carefully. While it fits standard elongated toilets, some older models have slightly different dimensions. I also would have checked if my bathroom outlet was GFCI protected. It is required for bidets.

The accessory I should have bought at the same time

I should have bought a water filter kit. While the S5 has an internal filter, a simple inline filter prevents any hard water sediment from reaching the complex EWATER+ system and the spray nozzles. It is a cheap insurance policy for a $780 unit.

The feature I overvalued during research

I overvalued the “pulsating” wash feature. In practice, I use the oscillating rear cleanse 95% of the time. The pulsating stream feels less effective and slightly ticklish. It is a nice option, but it did not end up being a deciding factor.

The feature I undervalued until I actually used it

I heavily undervalued the PREMIST feature. I thought it was a minor convenience. In practice, it is the defining feature of this seat. My toilet bowl stays significantly cleaner, and I have noticed a distinct reduction in residual waste sticking to the porcelain. It is surprisingly effective.

Whether I would buy the same product again today

Yes, I would buy it again without hesitation. The combination of instant water heating, reliable cleaning, and the automated bowl maintenance (PREMIST/EWATER+) has genuinely changed my daily bathroom routine for the better.

What I would buy instead if the price had been 20% higher

If the price were 20% higher (around $936), I would skip the S5 and look at a complete integrated smart toilet, such as the TOTO Neorest or a high-end Kohler integrated unit. The S5 provides massive value at its standard price, but at $936+, you enter the territory of complete luxury toilets.

Pricing Reality Check

At the time of this review, the current price is 780USD. Is it fair? Yes it is, given the specific feature set of PREMIST and EWATER+. You are paying for engineering that reduces long-term maintenance. The price does fluctuate on Amazon; it often drops to around $650-$700 during Prime Day or Black Friday events. The price is relatively stable outside of these major sale events. The total cost of ownership is low. There are no subscriptions. The filter replacement is recommended every 2-3 years depending on water hardness. Electricity usage is minimal (about $2-3/month). No toilet paper or cleaning chemicals are required, which offsets the cost slightly.

Warranty and After-Sale Support

TOTO offers a limited 1-year warranty for the WASHLET S5 covering defects in materials and workmanship. This is standard for the industry. The return window varies by retailer, but Amazon typically offers a 30-day window. I have not needed to contact customer support, but reading user reports, TOTO is generally responsive, though some users have reported slow shipping times for replacement parts. The warranty does not cover water damage from improper installation, so ensure your setup is perfect.

My Final Take

What This Product Gets Right

This product gets the core bathroom experience right. The instant hot water is perfect. The PREMIST bowl wetting is a stroke of genius that reduces cleaning. The EWATER+ self-cleaning wand gives unmatched peace of mind. This **TOTO WASHLET S5 review and rating** is as high as it is because of these three features working flawlessly together. The heated seat and deodorizer are excellent bonuses.

What Still Bothers Me

Two things still bother me. First, the reliance on the remote control; if I misplace it or the batteries die, I cannot use the wash features. A physical backup button on the unit would be a huge improvement. Second, the remote build quality feels a bit cheap for a $780 product. It works fine, but the buttons have a hollow click to them.

Would I Buy It Again?

Yes, absolutely. The comfort and hygiene benefits have made it indispensable in my home. I would buy it again in a heartbeat.

My Recommendation

My recommendation is to buy it. If you can find it on a slight sale, even better. This is a high-quality appliance that will serve you well for years. Go ahead and check the latest price for the TOTO WASHLET S5 if you are ready to upgrade your bathroom. I would love to hear about your experience in the comments below.

Reader Questions Answered

Is this actually worth the price, or is there a better option for less?

It depends entirely on your priorities. If you absolutely must have the PREMIST bowl wetting and the EWATER+ self-cleaning technology, then yes, it is absolutely worth it. No other seat in the $400-$700 range offers this exact combination. If you just want instant hot water and a dryer, the BioBidet BB-2000 offers comparable comfort for about $200 less, but you lose the automated bowl cleaning.

How long does it take before you really know if it works for you?

I recommend giving it at least one full week. The first 2-3 days are just adjusting to the seat position and finding your preferred water pressure and spray pattern. By day 5 or 6, you will know if you appreciate the clean feeling. By the end of week two, you will notice the difference in bowl cleanliness, which is a major benefit of the **TOTO WASHLET S5 review verdict**.

What breaks or wears out first?

Based on long-term user reports and my own testing, the most common wear items are the remote control (battery contacts corroding) and the seat hinge over many years. The EWATER+ system is designed specifically to prevent mineral buildup on the wand, which is the most common failure point on standard bidets. The heating element is very robust.

Can a complete beginner use this without frustration?

Yes, a complete beginner can set it up and use it. The installation is straightforward if you are handy with a wrench. The remote control uses simple picture icons. The main learning curve is remembering which button does what, but the “Stop” button is conveniently large. The most frustrating part for a beginner is correctly connecting the water hose.

What should I buy alongside it to get the best results?

I highly recommend buying a TOTO WASHLET S5 inline water filter. It prevents sediment from affecting the delicate valves. A small bathroom stool can also be useful for sitting comfortably during the longer air drying cycle.

Where is the safest place to buy it?

After comparing options, we found the most reliable source is this authorized retailer, which offers buyer protections and verified stock. Amazon also has a hassle-free return process.

Will the EWATER+ work with hard water?

Yes, EWATER+ is an electrolytic process that works on the minerals already present in the water. It is actually very effective in hard water areas because it targets the calcium and magnesium ions. That said, I still recommend a pre-filter to protect the rest of the unit from scale buildup.

Does the seat fit a standard TOTO Drake toilet?

Yes, it is designed specifically to fit TOTO’s elongated toilets, including the popular Drake and Ultramax models. The Sedona Beige (#12) matches the default TOTO bowl color perfectly. Make sure you have an elongated bowl, not a round one.
