TOTO UltraMax II WASHLET+ C100 One-Piece Toilet and Bidet System - 1.28 GPF

The TOTO UltraMax II Toilet features a sleek and sophisticated look along with superior flush power, thanks to TOTO's forceful Tornado Flushing system. In addition, the toilet’s bowl is coated with TOTO’s high tech CeFiONtect glaze, which creates an ultra-smooth barrier that deters residue from sticking, and the entire unit is a universal height, making it ADA compliant. Finally, TOTO designed the UltraMax II toilet to hide the C100 WASHLET+’s cords and hoses from view for a supremely streamlined look (this bidet seat, however, is only compatible with TOTO WASHLET+ toilets, such as the UltraMax II).

TOTO’s C100 WASHLET+ comes with all the features needed for a thorough and comfortable cleansing experience. Three wash modes (rear, soft rear and front) provide comprehensive cleaning, and the oscillating spray option causes the wand to move back and forth during the wash cycle for additional coverage and relaxation. The wand’s position, seat temperature, water pressure and water temperature are all adjustable, and a warm air dryer (with adjustable temperature settings) provides you with an alternative to scratchy toilet paper. What’s more, an automatic deodorizer kicks on each time the bidet is used to chase away any offensive odors, and the seat’s energy saving mode conserves electricity when the seat is not in use. Keep in mind that the C100 WASHLET+ comes with a tank water heater that provides a limited amount of warm water for washing. Should the tank run out, the unit switches to using ambient temperature water until the tank can refill and reheat, a process that takes a few minutes to complete.

All in all, the TOTO UltraMax II WASHLET+ C100 One-Piece Toilet and Bidet System has the looks and features you need to totally reinvent your bathroom routine!

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.
