TOTO Nexus Washlet+ S550e One-Piece Toilet - 1.28 GPF

The Nexus Washlet+ S550e One-Piece Toilet and Bidet System by TOTO features a sleek and modern silhouette along with the high performing S550e Washlet+. Together, they're designed to add comfort to your toileting experience while upgrading the look of your bathroom. The Nexus Toilet is equipped with TOTO’s powerful Tornado Flush System and utilizes an efficient 1.28 gallons to effectively sweep through the bowl with every flush. The Nexus’ bowl is also coated with TOTO’s signature CeFiONtect glaze, which creates an ultra-smooth ion barrier atop the toilet’s porous porcelain surface to prevent the buildup of mold, grime and residue. Furthermore, the Nexus toilet has been specially designed to conceal the cords and hoses of the S550e Washlet+ for a smooth, seamless look. In addition, it’s good to know that Washlet+ bidets are only compatible with Washlet+ toilets and vice versa, meaning that you won’t be able to mix and match the components of this Toilet and Bidet System with non-Washlet+ products.

The TOTO S550e Washlet+ is packed with high-end features that provide an unbelievably comfortable and convenient bidet cleanse. The S550e’s four wash modes (front, wide front, rear and soft rear) provide comprehensive cleansing, and the bidet’s adjustable spray wand cuts down on the amount of body repositioning required for a thorough wash. The S550e’s pulsating and oscillating spray options provide an additional level of relaxation and comfort, and the instant water heater ensures a continuous, never-ending stream of warm wash water. Adjustable water pressure, water temperature, seat temperature and warm air dryer temperature controls allow you to fully customize your wash and dry experience, and you can even program your favorite settings into the two user presets on the remote if you’d rather not select them manually each time you use the bidet. The S550e also comes with an automatic deodorizer that eliminates unwanted odor before it can take over your bathroom, and the built-in nightlight, which illuminates the bowl with a soothing glow, makes it both safer and easier to navigate the restroom in low light. For optimal convenience, the S550e is equipped with an automatic open/close lid that raises or lowers whenever someone walks towards or away from the toilet. What’s more, the S550e takes unit hygiene to the next level by using sterile, electrolyzed water (eWater+) to sanitize its nozzles after each use, as well as to premist the bowl prior to use to stop residue from sticking. 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.

All in all, TOTO’s Nexus Washlet+ S550e One-Piece Toilet and Bidet System offers high-end features, aesthetic appeal, and quality construction that simply can’t be beat!

This TOTO Washlet+ System comes with a 1 year warranty from TOTO.


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!

This TOTO Washlet+ System ships 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 support@manybidets.com 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 this TOTO Washlet+ System, 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.
