Carolina II WASHLET+ C100 One-Piece Toilet - 1.28 GPF

With its chic look and wide range of great features, the Carolina II WASHLET+ C100 One-Piece Toilet will add style to your bathroom while revolutionizing your day to day toileting routine. The toilet and WASHLET included in this system have been designed to fit together in such a way that the bidet seat’s cords and hoses are hidden from view for a sleek overall look (donote that only WASHLET+ bidet seats are compatible with this toilet). The Carolina II toilet is ADA compliant and a universal height, meaning that it stands a bit taller than standard height toilets, making it more accessible to a wider range of individuals, particularly those with limited mobility. It also features TOTO’s industry leading CeFiONtect glaze on the bowl to stop residue from sticking, and the Tornado Flush system powerfully sweeps away waste with a generous 1.28 gallon flush.

The C100 WASHLET+ included in this system is operated via a side-arm control panel conveniently attached to the seat. Do keep in mind that if you have difficulty looking down or experience limited upper body mobility, a seat with a remote may fit your needs better. There are three wash modes—rear, soft rear, and front—and the temperature and pressure of the wash water is adjustable to fit your preferences. The seat uses a tank water heating system, which keeps a set amount of warm water on hand at any given time. If you use up the warm water in the tank, either from using the seat several times in quick succession or running an extra-long wash cycle, the seat switches to using room temperature water until the tank can refill. The position of the wand can be adjusted so as to minimize the amount of body repositioning needed for a thorough wash, and an oscillating spray option increases cleansing coverage while soothing tender areas. In addition, the wash stream is pumped full of tiny air bubbles that gently increase cleaning power. This seat also comes with a warm air dryer with adjustable temperature settings, so there’s no need to use up toilet paper to dry off after a wash, and the air deodorizer discreetly eliminates embarrassing bathroom odors. The heated seat will keep your tush comfortably warm, and the energy saving mode cuts back on electricity usage for a healthier planet and a happier wallet.

All in all, the Carolina II WASHLET+ C100 One-Piece Toilet is an attractive and high performing addition to 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.
