TOTO Nexus WASHLET+ S550e Two-Piece Toilet and Bidet System - 1.28 GPF 

The TOTO Nexus S550e Two-Piece Toilet and Bidet System looks amazing and will transform your restroom experience with its broad range of luxury features. The Nexus toilet is coated with an ion-barrier, CeFiONtect glaze that stops mold and residue from building up, and the Tornado Flush System powerfully sweeps through the bowl with 1.28 gallons of water each time the unit is flushed. Furthermore, the TOTO Nexus is a WASHLET+ toilet, meaning that it has been specifically designed to hide the water and electrical connections of the S550e WASHLET+ bidet seat. Do note that WASHLET+ toilets and bidets are only compatible with one another and can’t be mixed with non-WASHLET+ products.

The TOTO Nexus S550e WASHLET+ has all the features you need for a supremely comfortable and convenient wash, including four wash modes (front, wide front, rear and soft rear), oscillating and pulsating spray options, and adjustable water temperature, water pressure, seat temperature and wand position. The instant water heater ensures that you’ll always have warm wash water, and the automatic deodorizer works hard to discretely eliminate unwanted bathroom odors. Additionally, the warm air dryer provides a gentle drying experience and gives you the option of bypassing scratchy and expensive toilet paper. The S550e also comes with a built-in nightlight that makes it both safer and easier to use the bathroom in low light, and the automatic open/close lid enables you to have a virtually hands-free bathroom experience. Two user presets allow you to program your favorite wash settings into the remote so you don’t have to manually select them each time, and the seat’s energy saving mode cuts back on the amount of electricity it consumes when not in use. Furthermore, the S550e is equipped with sterile EWATER+, which sanitizes the nozzles after each use for optimum unit hygiene. 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. 

With its range of high-end features and chic, sleek design, the TOTO Nexus S550e Two-Piece 1.28 GPF Toilet and Bidet System provides a stellar toileting experience from start to finish.

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.
