TOTO Vespin II WASHLET+ C100 Two-Piece Toilet and Bidet System - 1.28 GPF

The TOTO Vespin II WASHLET+ C100 toilet and bidet system offers an array of features designed to instantly upgrade the quality and comfort of your toileting routine. The Vespin II toilet features a generous 1.28 gallon flush along with TOTO's forceful Tornado Flush Technology and ultra-smooth CeFiONtect bowl glaze that help keep the unit free from residue and build-up. In addition, the Vespin II toilet was designed to specially accommodate WASHLET+ bidet seats like the C100 WASHLET+ and is able to hide the bidet’s cords and hoses from view for a seamless, streamlined look.

The TOTO C100 WASHLET+ offers all the features needed for a comfortable and thorough wash and dry experience. The seat offers three wash modes—front, rear and soft rear—as well as an oscillating spray option that moves the wand back and forth for wider wash coverage and additional relaxation. The C100’s water temperature, water pressure, and wand position are all adjustable, and the tank water heating system provides a limited amount of warm wash water. While the tank holds plenty of water for a standard wash cycle, it may run out if the bidet is used several times in a row or when running a long wash. If that happens, the unit switches to using room temperature water until the tank can refill and reheat, which usually takes a few minutes. Thanks to the C100’s built-in warm air dryer with adjustable temperature settings, you’re no longer dependent on costly and abrasive toilet paper for drying off, and the seat’s deodorizer automatically turns on each time the seat is used to get rid of unwanted odors. The C100 is operated via a side arm control panel attached to the side of the seat, and an energy saving mode reduces its electricity draw when it’s not in use to conserve resources and save you money over the long haul.

With all the features you need for an effective and comfortable cleansing experience, the TOTO Vespin II WASHLET+ C100 toilet and bidet system provides an excellent introduction to the world of quality bidets.

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.
