TOTO Supreme II WASHLET+ S350e One-Piece Toilet and Bidet System - 1.28 GPF

The TOTO Supreme II Toilet that is included in this toilet and bidet system doesn’t just look great, it performs well too. Equipped with TOTO’s special Tornado Flush technology and a coating of CeFiONtect glaze on the bowl, the Supreme II toilet mounts a masterful defense against residue accumulation. The toilet itself is a universal height and ADA compliant, so it’s accessible to a wide range of individuals, and it’s been specially crafted to hide the cords and hoses of the S350e bidet seat that is included with your purchase.

The S350e WASHLET+ bidet seat comes with nearly every feature available on the market today for a truly exceptional experience. Four wash modes (front, wide front, rear and soft rear) provide thorough cleansing, and the wash water pressure, water temperature, wand position, and heated seat are all adjustable according to your personal preferences. Oscillating and pulsating spray options provide extra relief and relaxation, and the seat’s warm air dryer provides the option of foregoing expensive and abrasive toilet paper. The S350e comes with a built-in deodorizer to eliminate unwanted odors, and the nightlight illuminates the bowl with a gentle glow to make nighttime restroom trips both safer and easier. The automatic open/close lid gives you the option of a truly hands-free bathroom experience, and it’s also sure to wow your guests. Two user presets provide additional convenience by giving you the option of programming your favorite settings into the remote for a fully customized wash at the touch of a button. What’s more, the S350e uses sterile, electrolyzed water (EWATER+) to coat the bowl prior to use—thereby making it hard for waste to stick—and to sanitize the unit’s nozzles after each use for added hygiene and peace of mind.

Whether you’re new to the world of bidets or have enjoyed their benefits for years, the TOTO Supreme II WASHLET+ S350e One-Piece Toilet and Bidet System is sure to impress!

The TOTO Washlet+ comes with a 1 year full warranty for residential use, and a 1 year full warranty for units installed for commercial use.


We cover tax at the prices quoted, so no need to worry about a surprise tax fee added on during checkout, we've got you covered!


We also pay for shipping, so the price you see is the price you get!

TOTO Washlet+ units ship via freight, and ships on a pallet.  The shipper will call you when the unit is in your area and ready to be delivered. This allows you to schedule delivery, so you don't need to worry about it being delivered when you're not home.  Because toilet bowls are fragile, we recommend looking over the unit quickly when it arrives.  It's very rare for anything to be cracked, but it has happened.  We see about a 5% break rate, meaning about 1 in 20 have damage. When the unit arrives, look it over before signing for it. If anything is broken, don't sign for the package. Instead, take pictures and email them to or text them to 248-974-4030, and refuse delivery. This allows us to file a claim with the shipper and get another one out to you within 24 hours.


Because of the fragile nature of toilet bowls, returning one is a tricky process.  Should a return be required on your Washlet+ unit, TOTO requires that it be shipped back via freight, and shipped back on a pallet.  TOTO also charges a restocking fee of 30%, and will not cover shipping either way. TOTO also requires that the unit come back in 100% brand new condition. If the unit comes back in any condition other than 100% brand new, resellable condition, no refund of any sort will be issued.
