## Description

The TOTO K300 WASHLET® Elongated Electric Bidet Toilet Seat with Tankless Instantaneous Water Heating with PREMIST® and SoftClose® Lid is an electronic luxury toilet seat that cleanses you with warm water, providing an exceptionally fresh feeling. Unlike traditional toilet paper that can often be rough and ineffective, the WASHLET® quickly provides comfortable warm water cleansing at the touch of a button. A once mundane trip to the bathroom can become a spa-like experience with the addition of a WASHLET®. The TOTO® WASHLET® K300 features instantaneous water heating with five spray settings for front and rear washing, including an optional oscillating or pulsating stream. Equipped with a comfortable heated seat, warm air dryer, and a deodorizer to neutralize odors and enhance your overall experience. The illuminated remote control can be handheld or mounted to the wall for convenient use. PREMIST® wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The new K300 model utilizes TOTO's EWATER+® system when the wand self-cleans. EWATER+ transforms the water into a safe and powerful compound, creating peace of mind by cleaning the inside and outside of the wand before and after every use. The WASHLET® reduces the need for toilet paper, thus conserving trees and water used to manufacture each roll. As we get older, reduced mobility, medical conditions, and debilitating illnesses can make it increasingly hard to clean ourselves after using the toilet. With a WASHLET, just the touch of a button can leave you feeling clean and refreshed. Easy to install and includes mounting and connection hardware.

Review: Comfortable, stable, great remote, attractive, easy to use, good water pressure. - Overall a great product and value. My family had 3 Toto washlets from the early 2000s that all lasted more than 20 years with daily use (2 finally died, one is still going), so going back to a Toto was an easy decision. the build quality is not the same as it once was, but the price is literally half of what I paid over 20 years ago, so a lesser build quality was inevitable and I’m ok with it even if I get half as long a life as I did on the old units. Great remote that is easy to use after a quick read of the manual, and lots of features and options. The unit is easy to install - no plumber required and I was able to get it on in about 45 mins and I’m slow at assembling things. It sits on the bowl in a stable way which I’m mentioning since my old unit would slip off narrower bowls (which might have more to do with the toilet design and not the Toto). I suppose it could snap the fastening cradle if a heavier person leaned to one side on a narrow bowl and the unit slips off to the side. Also, compared to my old unit I would say there is a little more wiggling in the cradle that fastens it to the bowl. Pretty sure I have screwed it in tightly enough, so I’m assuming it’s the product’s design. This isn’t a big concern, just something to be aware of. It is comfortable to sit on, but one thing to note: The top lid pretty much sits straight up. This means you really can’t lean all the way back to the tank. However, the sides of this lid are designed so they come to a sharp enough edge that it could potentially irritate your arms if they were to rub against the lid (see pic). It’s never been an issue, but if you somehow used the unit differently than me, I suppose it could be bothersome. It’s a design flaw - no way to know in advance, it’s just something you’d have to try for yourself and see how it goes. The unit is more attractive than my old one with a slightly slimmer and lower profile and a nice bright white color. Lastly, the water pressure. At full throttle, I would say the pressure is about 80% as strong as my old unit. It’s more than acceptable for all levels of hygiene, but it’s worth pointing out in case high pressure is your preference. The pressure specs according to the user manual are the same for all Toto units, so if you’re really into a high pressure stream, you’d have to do some brand shopping. So a couple of small design points, but overall a great product and value.
Review: Beats the (dated) Brondell Swash 1000 or 1400 - Looks great and high in quality / value. After 5yrs using our first washer seat, a Brondell Swash 1000, and being very pleased with it, the seat cracked exactly in the back middle with a growing, pinching (ouch) gap. We're both well less than 200 pounders, LOL, and it was installed in our personal, main suite bathroom, our kids are grown and so just us 2 adults that used it. We even kept the seat settings always at lowest heat setting and in Eco Save mode, so it cannot be from degradation from long term high heat exposure, either. After 5 years, we almost rebought the 1000 and even looked at the 1400 Brondell model, but the pics and reviews online showed these models have this seat crack as a known latent defect and reportedly Brondell acting difficult about handling it as such (an epidemic defect that's out of warranty). Also, water leaks reportedly, commonly emerging as units age (although fixable with the YouTube videos out there) was concerning. I'd like to point out the basic functionality here was a "seat" first and foremost, and frankly the expensive Brondell built basic seat functionality failed miserably! Disappointed, we started shopping around ... We previously bought a Toto Neorest washer as a part of a full replacement potty unit ($$$) when doing our second bath's remodel last year because it looked so cool (looks like a big egg). It was expensive, but we were determined to have style and a washer type unit after being sold on the concept by our first Brondell Swash 1000 add-on seat experience. We love the Toto Neorest. So now that we were forced to re-shop for our main bathroom this time, Brondell was a natural, cost effect and darn good add-on solution again to just fix it or possibly replace the seat. BUT, after 5 yrs it was aging and looked it. When replacing and with a few more dollars, the competitive Toto K300, along with our added prior Toto experience, and the online reports of Brondell quality and service issues, we decided to make the leap to go Toto washers for both bathrooms. After the easy replacement install (wall electrical outlet already existing from the Brondell unit) and seeing the difference in quality (design and materials) side by side (Brondell Swash1000 and Toto K300), we also experienced what we first thought would be a less effective, more soft-cleaning (comfort) performance than what the Swash 1000 produced (or even the Toto Neorest). After using several times, we wrongly doubted its performance and now very glad we made the Toto choice again with the K300. Somehow, the Toto K300 manages to clean better and seemingly more easily (less harsh spray) than the Brondell Swash 1000 (would typically use full force to get spotlessly clean) or even its Toto big brother, big buck, Neorest (it is less harsh in capability than the Brondell, and more like the K300 in experience, but Neorest also is somehow not as a complete in clean experience - and we always paper check!). Surprisingly, this K300 best overall performance comes along and beats a similar, cost competitive, easy install, add-on unit like the Brondell Swash as well as the fully optioned Toto Neorest total potty unit we first bought ($$$)! Note Brondell's Swash 1000 and Swash 1400 models are built on the same design platform and use the same parts, including the latent defect seat, which is why I threw the 1400 into this review. Bottom line, spend the few dollars more and buy the Toto K300 for its looks, quality and performance. Toto K300 looks sleeker, lower, leaner and more modern than the Brondell Swash 1000 and 1400 and goes about performing "the job" better. Although not U.S.A. built, the Toto is marked as made in Malysia, and not China. As initially expected with the Brondell, subsequently sent to the trash bin, we certainly do not expect our Toto seat(s) to crack no matter how old they get and will update if that ever happened.

## Questions & Answers

**Q: Fit dimensions on the toto website show a minimum width dimension from center of toilet to the outer side edge of 8". i have 7.25" is this necessary?**
A: Hello, The 8 inch requirement is for open space. Some toilets have tanks that curve inward and would impede the WASHLETS ability to slide back onto the toilet. There must be a minimum of 2 inches from the seat mount holes to the front of the tank, and this 2 inches must be all the way across the width of the tank out to 8 inches. If your toilet bowl is only 7.25 inches wide, but the tank does not curve inward you should be fine.  Hope this is helpful. If you need additional assistance, please reach out to us directly. Our Technical Support team is standing by to take your call. They can be reached at techsupport@toto.com or call 1-888-295-8134 between 8am - 8pm Mon - Fri EST and press 4 when prompted. We also have live chat on the TOTO USA website. I hope this helps and thank you for choosing TOTO.

**Q: is the timer in the remote (where you set it) or in the unit? If the AC goes out do you have to reset the timer or only when you change batteries?**
A: Unlike my old unit that was from another manufacturer, this one doesn't time out that I am aware of....  You cycle through the options manually at whatever length you want and hit the next feature button or the stop button on the remote to end a feature and push the next button in the sequence you desire.  Usually, front or backwash, oscillation, then air dry and stop.  It supplies warm water throughout either of wash cycles (front or back)  and doesn't run out of warm water like other units.  Everything is controlled via the remote which you can mount on the wall with the included bracket.

**Q: What is the weight limit of this particular washlet? Would it support someone that is 500#’s +?**
A: I would guess that it would not support 500 lbs. It isn't the sturdiest seat. I weigh 180 and the thing creaks quite loudly under me. Also, the way it attaches to the bowl makes it difficult to get a very solid connect -- so any shifting of my weight makes the seat shift -- more creaks and sometimes will even slip the feet off of the bowl. I have also owned a Brondell bidet seat. The Toto is better in every way except for the seat. The Brondell had a very sturdy seat.

**Q: I have three water spigots behind my toilet. If I use the odd one, can the toilet be flushed normally bypassing the washlet??**
A: Hello, The WASHLET will connect to the tank fill valve inlet with an included adapter. The WASHLET operate independently of the toilet flushing mechanism. Please take a look at the installation diagram provided on the page. If you need additional assistance, please reach out to us directly. Our Technical Support team is standing by to take your call.

### ⭐⭐⭐⭐⭐ I don't know how we would do without them!
*by T***P on February 17, 2026*

We bought one of these for each of our bathrooms after seeing/trying one in a friend's house. They work great and help make you fresh and clean and the warm seat so cozy during this cold winter. The deodorizing fan works well too, seldom need to use the ceiling fan in bathroom. Comes with everything including water supply "T". Easy install except you will need a convenient AC outlet nearby. If you are lucky the longish cord will reach, if you are handy you will install an outlet for it, if you aren't stand by... an electrician will charge as much as the cost of this bidet seat!
