auto open and close lid


Enjoy an exceptional level of luxury when the lid opens upon your approach and closes on your departure.

instantly heated water


Continuous warm water stream will last as long as you need it, and the absence of a water heating tank creates a minimalistic, streamlined design.

e-water and sanitation technology


With no chemicals or cleaning agents, electrolyzed water automatically sprays the bowl after each use to prevent any microscopic build up.

wave technology


Provides a strong, yet gentle cleansing stream by injecting the water with air to enlarge the droplets. Smaller droplets collide with larger ones and fill with more air, creating a satisfying cleanse.

automatic nightlight


A soft light gently illuminates the room when you approach your WASHLET.

warm air dryer


Enjoy the ease and comfort of the gentle, hands-free, temperature-adjustable dryer.

air deodorizer


WASHLET draws in air and neutralizes unwanted odors using a powerful ionized carbon filter.

eco-friendly spray technology


With WASHLET, there’s a decreased need for toilet paper, so you help the environment by reducing the trees and water used to make each roll.

self-cleaning wand


The self-cleaning wand is engineered to repel particles and prevent adhesion, rinsing itself before and after each use.

outlet required


WASHLET requires a 120V GFCI outlet when connecting the included 3.94’ Power Cord.

The TOTO Washlet S350e round bidet seat delivers ecology-minded luxury in a slim design. The Washlet features TOTO's technologically advanced ewater+ system which uses electrolyzed water generated by a technologically advanced process, transforming the water into a safe and powerful compound. By misting the bowl after every use, the ewater+ technology helps to keep your toilet bowl clean and hygienic without any extra harsh chemicals. The Premist function sprays the bowl with water before each use, preventing waste buildup and keeping the toilet bowl clean. The TOTO Washlet S350e is fully automated, including an illuminated remote control with 5 spray settings, auto open and close lid, heated seat, and instantaneous water heating. Cleansing with soothing warm water is more comfortable than traditional toilet paper that can sometimes be rough. Using a Washlet reduces the amount of toilet paper needed. Not only are you saving the trees that make toilet paper, you're also saving the water used during manufacture. One roll of toilet paper requires four gallons of water to make! As we get older, our mobility can deteriorate and make it increasingly hard to clean ourselves after toileting. Medical conditions such as ALS, MS and other debilitating illnesses can make using the bathroom without assistance almost impossible, but with a Washlet, just the touch of a button can leave you feeling clean.

I have major blowouts I suspect would contaminate the wand and bowl. Electrolytes sound like a sports drink. Would they remove major effluence?

Asked by Michelle2020Obama December 17, 2019

Hello Michelle2020Obama, No need to worry about your blowouts. Everyone experiences them and most people do not report a problem with them and the WASHLET. The wand will come out to spray the PREMIST, but will then retract back in to the unit. It will not come out during use until you are ready and press the button. The electrolyzed (not electrolyte) water is sprayed onto the bowl after you finish to help prevent build-up on a microscopic level, but does not breakdown larger bits of debris. This can help keep your toilet clean longer, but you will still need to clean it on a regular basis. Please take a look at the reviews to see what people are saying about the WASHLET. We hope this helps and we thank you for your interest in TOTO!

Asked by Totofan June 24, 2018

Wand is kept sanitary by their “e-water+” system. The system sprays this water on the wand from within a chamber. There are also instructions for manual cleaning (which they suggest monthly) in the manual.

Asked by Susan March 6, 2017

Hi Scrappy, I can't answer your question on whether or not Home Depot can install your outlet. But I can help you determine whether or not a TOTO WASHLET will fit on your Kohler toilet. Please take a look at the fit chart for the TOTO WASHLET: https://washlet.totousa.com/images/fitting/washlet-compatibility-chart.pdf A couple of other things to consider are seat mounting holes and water supply connection of the toilet. Both of these will need to be standard and not a special proprietary design. Most toilets will be standard, but some special designs interfere with installation. If you need more help, please reach out to TOTO Technical Support at 1-888-295-8134 between 8am - 8pm EST and press "4" when prompted. Hope that helps and thank you for choosing TOTO!

who will install it when you have no electric socket and you are not handy with the plumming

Asked by John November 21, 2016

Hi John, You'll need to have an electrical outlet nearby. TOTO does not recommend the use of an extension cord with the Washlets. Once you have an outlet, the Washlet install is very simple. You do not need to be very experienced with plumbing to install the Washlet onto your toilet. Here is a video to guide you: https://www.youtube.com/watch?v=_9DAGF1cJK8 Hope that helps and thank you for considering TOTO!

The S350e for round toilet bowls suffers from some convenience-feature flaws, and for the cost and the brand you’d expect a well-thought out, flawless experience. Keep in mind that from what I understand, this is the BEST money can buy in the round toilet bowl landscape. - I was expecting to not like the “traditional” shaped cover but it actually looks rather nice. - Installation was super simple though the instructions added to the confusion instead of alleviating them. - Basic use is as expected, it’s a bidet. - Heated seats can get very warm which is nice. Many temperature options for operation. - Seat space is extremely limited, to the point where taller or larger people may not fit properly. You may be better off buying a cheap elongated toilet for your expensive bidet. - Bowl light is most disappointing feature - it does not stay on for more than 2 seconds on approach and there’s no option to turn it on manually. Why even have one? - Lifting the cover and seat via button is extremely pleasant, I didn’t expect how convenient this would be. - Dryer could be more effective but she tries. - Seems very sturdy and will last a long time if following the many cleaning warnings in the manual. All in all, a decent product but for a premium price but you may want to install a non-round toilet if possible.

This is a life changing appliance - I can not speak highly enough about this thing! The install can be a little tricky with the old T-valve connection. I had to use plumbers tape on the threads - but that did the trick - no leaks now! Yes - this is worth the money, Yes - the extra bells & whistles are worth it - you can thank me later :)

Had a little trouble with water connnections. Had a 35 year old water supply hose in old style corrugated metal, and could not get the connection to the adapter supplied with the Washlet to fit in a leak tight seal. Had to call a plumber who installed a complete new water supply hose with replacement angle stop valve and then it all worked very nicely. After all connected and power connected the Washlet works very nicely. My wife and her friends love it.

This bidet broke itself just from a wipe down
Over priced, terrible design, overtly delicate and will NEVER be sanitized no matter how much you clean it. I had it only for a year. I couldn't be ANYMORE DELICATE with cleaning this expensive, difficult-to-clean product. After sanitizing it, the bidet stopped working! The wand no longer stays out to clean or spray-- It immediately retracts itself. The dryer also stopped working. It longer responds to the control as well. Now I have to waste a lot of money to send it to the states to get it repaired. Do not get this product until technology and design improves. You're wasting money and physical energy in the long run and it just gets VERY dirty in places you can't reach to clean. I don't feel and think it's clean when I use it. Rust and dry watermarks build up where the wand comes out and there is plastic jutting out and crossing here and there so you can't reach in to clean it! The wand is also VERY much in the way of cleaning. Summary: First time owning a bidet and never again. You will have DIFFICULTIES cleaning this and it will break no matter how delicate you handle it. I don't want to own another bidet ever again. BAD AND COMPLEX DESIGN that helps bacteria fester.
