TOTO UltraMax II 1G WASHLET+ S300e One-Piece Toilet and Bidet System - 1.0 GPF

TOTO’s high-performing UltraMax II 1G WASHLET+ toilet is ADA compliant and boasts a classy silhouette that instantly upgrades the style factor of any bathroom. In addition to featuring TOTO’s powerful Tornado Flush technology, the UltraMax II’s bowl is also coated with CeFiONtect glaze for an ultra-smooth surface that deters waste residue from sticking. Furthermore, the UltraMaxII is specially designed to conceal the cords and hoses of the C300e WASHLET+ bidet seat that comes included in this system (do note that the C300e WASHLET is only compatible with WASHLET+ toilets).

The C300e WASHLET+ bidet seat comes with a wide array of features designed to maximize comfort and convenience. Four wash modes (front, wide front, rear and wide rear) ensure comprehensive cleansing, and the instant water heater provides unlimited warm wash water. The water temperature, water pressure, seat temperature and wand position are all adjustable for a fully personalized experience, and the oscillating and pulsating spray options provide additional comfort during the cleansing process. The C300e also features a warm air dryer with adjustable temperature settings for a hands-free experience start to finish, and the automatic deodorizer chases away unwanted restroom odors. The C300e even comes with TOTO’s signature EWATER+, which is sterile, electrolyzed water used to mist the bowl prior to use to deter residue from sticking and to sanitize the unit’s nozzles after use for optimum unit hygiene. Finally, two user presets allow you to program your favorite wash settings into the remote for extra convenience.

All in all, the TOTO UltraMax II 1G WASHLET+ S300e toilet and bidet system provides the perfect refresh for any 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.
