About This Product

The TOTO WASHLET KS6 features instantaneous water heating with 5-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. The K300 prevents toilet bowl waste buildup by using TOTO's advanced PREMIST technology that sprays the bowl before every use to keep it clean. The new K300 model utilizes TOTO's EWATER+ system when the wand self-cleans. EWATER+ uses electrolyzed water generated by a technologically advanced process, transforming the water into a safe and powerful compound. This cleaning technology helps to keep create 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.

Highlights

  • Tankless, instantaneous water heating means never running out of warm water
  • Premist- using incoming water supply, a misting of the toilet bowl is performed before each use to help prevent waste from adhering
  • Wand self-cleans inside and out with ewater+advanced technology
  • Heated seat and warm air dryer with 5-adjustable temperatures
  • Remote control operated with 2-user memory to save preferred settings

          Why is the process to turn the night light on so complicated? Is this brand a joke? It's the equivalent of a Sega Genesis Mortal Combat finishing move sequence to remember just to turn the night light on and off. So inconsistent.

            Weight limits for ks5 and ks6?
            ByFeb 22, 2026
            1 Answer | 
            Answer This Question

            Hello, The WASHLET seat meets the structural integrity criteria for any toilet seat sold in the US. Under normal use, the WASHLET seat is capable of holding quite a bit of weight; however, regardless of the weight of the individual, care should be taken not to excessively twist or slide sideways across the seat, as this can compromise the plastic components. All WASHLET functions will be operable and do not max out with too much weight. The seat does have ultrasonic welds that hold it together, so the longevity of the seat could be affected by the weight of the individual. For help with your specific question, please call TOTO Technical Support to gather more details on the weight capacity. 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. Hope that helps and thank you for considering TOTO!

                  Highly recommended
                  I’ve been extremely impressed with the TOTO KS6 Washlet. It completely upgraded my bathroom experience and pairs beautifully with modern one-piece toilet Swiss Madison St. Tropez. Once installed, it feels like a fully integrated bidet toilet system rather than an add-on. The design is sleek and low-profile, with a clean, contemporary look that blends in perfectly. It doesn’t look bulky or “aftermarket.” The fit and finish are excellent, and the soft-close lid and seat feel solid and well-built. Performance-wise, it delivers exactly what you’d expect from TOTO. The water pressure is strong and consistent, the temperature control is accurate, and the heated seat is a game changer—especially in colder months. The controls are intuitive and easy to adjust, and the different wash modes provide a comfortable and customizable experience. Installation was straightforward, and the unit feels reliable and thoughtfully engineered. What stands out most is the value: when combined with a quality one-piece toilet, it creates a high-end integrated bidet setup for a fraction of the price of a fully integrated luxury model. If you’re considering upgrading to a washlet, the KS6 offers excellent performance, premium features, and a polished look without going into ultra-luxury pricing. Highly recommended.

                    This Toto KS6 Washlet Electric Bidet seat was a game changer! The bidet feature was what I was mostly interested in for the absolute best derriere cleaning, which works splendidly. However, I cannot live without the heated toilet seat future now! The fact that it's lit is also an extremely valuable characteristic. The only down side is the drying takes longer than I can wait so I usually just finish drying with some tp. We love it so much that we've installed bidets on all of our commodes and have recommended them to parents and friends!

                    After traveling Japan, my wife and I both became fans of the Toto Bidet. Found everywhere, even in Public restrooms, it is of high quality and dependable. The K300 has the features you’ll want, instant hot water, customizable settings. It just makes the go so much more pleasant. And when I found it available at Home Depot, we purchased it for both our homes. While they make a bidet with fewer features, I can only recommend the K300, you deserve it. And it fit our existing toilets

                    perfect temperature!
                    This bidet is amazing. The temperature is perfect every time. The water never runs out or changes temperature. TotoUSA is mokes above other bidets. I will by another K300 or maybe a 550e if i can go up a bit higher in price for more bells

                      This Bidet toilet seat is quite easy to install. The only problem can be if you do not have a 110-volt electrical outlet within 3 feet of the seat. The only tools I needed was a Philips screwdriver to tighten the seat screws. It took me longer to learn how to use it than install it. I spent about 30 minutes installing it. It is nice to have remote control instead of mounted on side of toilet. The instructions included can be a little hard to understand but there is a good video on Home Depots web site. Just search for Toto Washlet SW3036r. This model has all the modern features on premium models. There is a pre-mist spray that starts the process to help keep bowl clean. Features are heated seat, soft closing lids, deodorizer fan and filter, tankless water heater, warm air dryer, self-cleaning wand and air injected water stream for better cleaning. I could not find, in instructions, how to release the seat for cleaning. There is a button on the right side of the seat towards the back you need to push, then pull seat straight out. I had trouble, at first, with the remote not working. I found that I needed to point the remote in the direction of the back of the seat. I mounted the remote on wall with Velcro instead of screws due to marble wall. This was my first experience with a bidet, and I have found that it works well and saves a lot of toilet paper. Bottom line, it works!

                      TOTO ELECTRIC BIDET IS SO COOL I COULD COME UP WITH MULTIPLE ADJECTIVES TO EXPRESS THE WORKMANSHIP, APPEARANCE & AFFECT in not only cleaning me but also itself after each use. Measuring from back of LED panel to front seat is 20 3/4 in. long & 14 1/2" width, 3 prong power plug is 4 ft. Water supply hose 2 ft in length. Seat cover is soft close, LED panel displays power, seat, energy saver & wand clean. I love that all can be done with hand held remote that can be mounted neatly on your wall. 3 Manuals in 3 different languages. Instructions are very thorough and can be installed (assure seat is mounted snug) within 30 minutes including seat, I am working on the anti theft for the remote, personally living alone Im not concerned. Front of the remote is used for you, back of the remote is use of self cleaning Toto Washlet Once assembled I sat and noticed the warmth of the seat, too cool! Features are Incredible allowing rotation of the cleaning wand to rotate left, right, back and forth. Then comes the drying power, no more worries of toilet paper shortages Toto is replacing a previous bidet, my opinion no comparison

                      Let me save you a lot of time ... if you live where tap water is cold and you want to minimize TP use and save water, buy this! I have tried handheld sprayers (awkward), seats with non-heated water (cold), seats with heated water but no drier (use almost as much TP drying water). I have even tried diverters, that let you mix Hot & Cold water (waste gallons waiting for the Hot to make it up from the basement water heater [I would run the Hot in the sink, before I would sit down]). This, with its instantaneous warm water, saves water and power (only heats water when in use). The air dryer, truly saves on TP (takes about a minute to dry). I like a remote. Being right handed, I use my right hand to guarantee the water did its job. I do not want to be changing controls with a wet hand (controls typically mounted on right side). I use the remote in my dry (clean) left hand. You get all this, and it is still relatively low profile (does not look like some big contraption mounted on the toilet). The remote allows you to save setting for two people. It sets water temperature, pressure and angle, seat temperature, fan temperature, energy saving modes. My previous bidet seat, the Low seat temp was warmer than I would prefer (warm like someone just used it). This one, the Low just takes the chill out of the seat (using less energy). Super easy to install, as long as you have an outlet near the toilet (Do not use an extension cord). Max power is 1430W; which is like a Hair Drier on High or a Space Heater. If your outlet can handle that, it should have no problem with this . So far, no negatives. I am loving it. I also use it between showers, to freshen up. The Deodorizer, I thought might be gimmick, but it actually does work. The PREMIST washes everything down, before each use. The EWATER+ , hard to tell if it does anything, but nice to think it does. Only thing this is missing, that my last one had, is a light for the bowl, but I never found that feature very useful.
