TOTO Nexus 1G WASHLET+ S500e One-Piece Toilet - 1.0 GPF

The TOTO Nexus 1G Washlet+ S500e One-Piece Toilet offers a sleek silhouette and a range of luxury features that will take your bathroom experience from mundane to marvelous. TOTO’s Nexus 1G toilet is a WASHLET+ toilet, meaning it’s been specially designed to hide the cords and hoses of the S500e WASHLET+ from view for a streamlined look (installation does require an adapter kit, sold separately). Do keep in mind that WASHLET+ bidet seats are only compatible with TOTO WASHLET+ toilets, so they can’t be mixed and matched with traditional toilets. The Nexus 1G toilet features an efficient 1.0 gallon flush powered by TOTO’s powerful Tornado Flush System, and its bowl is coated with CeFiONtect ion-barrier glaze that prevents residue and mold from gaining a foothold. In addition, its smooth, skirted design makes it easy to wipe clean.

The TOTO S500e WASHLET+ has a wash mode for every situation (rear, soft rear, front and wide front), and the pulsating and oscillating spray options soothe tender areas and can help stimulate the bowels. The seat temperature, water temperature, water pressure and wand position are all adjustable for maximum convenience and comfort, and the S500e’s instant water heating system guarantees unlimited warm wash water. Once your wash is complete, you can enjoy a toilet-paper free drying experience compliments of the S500e’s warm air dryer, which has adjustable temperature settings, and this feature is particularly helpful for those with painful bowel conditions or physical mobility limitations that make wiping painful or difficult. Once the seat is in use, the unit’s automatic deodorizer function kicks on to eliminate any unwanted bathroom odors, and sterile EWATER+ sanitizes the bidet’s nozzles after each use for optimum unit hygiene. Two user presets allow you to program your favorite settings into the remote for a personalized, one touch wash each time, and the seat’s energy saving mode cuts down on electricity consumption when it’s not in use. 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 sleek, modern look and broad range of luxury features, it’s easy to love TOTO Nexus 1G Washlet+ S500e One-Piece Toilet and Bidet (1.0 GPF).

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.
