TOTO Nexus WASHLET+ S500e One-Piece Toilet and Bidet System - 1.28 GPF

The TOTO Nexus WASHLET+ S500e Toilet and Bidet System is designed to take your bathroom experience to the next level, both in terms of comfort and style! The Nexus one-piece toilet features a seamless and contemporary look and is constructed from a single piece of porcelain. Its 1.28 gallon flush is powered by TOTO’s forceful Tornado Flush Technology for optimum effectiveness, and the CeFiONtect glaze coating the porcelain bowl creates a super-slippery barrier that stops mold growth and residue accumulation. For additional cleanliness, the S500e bidet seat included with this system comes with a PREMIST feature that coats the bowl with a thin film of sterile water prior to use in order to stop waste from sticking to the bowl. Both the Nexus toilet and the S500e bidet seat are WASHLET+ models, meaning they’ve been specially designed to fit together in such a way that the bidet seat’s cords and hoses are neatly concealed from view. Do note, however, that WASHLET+ products cannot be interchanged with non-WASHLET+ items.

The TOTO S500e WASHLET+ delivers a comfortable and convenient cleanse, thanks to four wash modes (front, wide front, rear and soft rear), pulsating (massage) and oscillating (back and forth) spray options, an instant water heater that provides never-ending warm wash water, and adjustable seat temperature, water temperature, water pressure, warm air dryer temperature and wand position. The seat’s warm air dryer provides a gentle and economical drying alternative to abrasive, expensive toilet paper, and the automatic deodorizer gets rid of unwanted odors before they take over the bathroom. The bidet’s energy saving mode cuts down on the electricity used by the seat in between bathroom trips, and two user presets allow you to program your favorite wash settings into the wireless remote for a one-button, personalized wash and dry. In addition, the S500e uses sterile, electrolyzed water (EWATER+) to rinse the bidet’s nozzles after each use for a sparkling clean unit. Last but not least, this system is available in both non-auto flushing and auto-flushing models, the latter of which flushes the toilet when a user stands up and moves away from the unit.

The TOTO Nexus WASHLET+ S500e Toilet and Bidet System is an excellent option for transforming the comfort and quality of your toileting experience, all while adding style to your bathroom.

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.
