The TOTO C100 Washlet (SW2034, SW2033R) is an entry level bidet toilet seat from industry leader TOTO USA. Built with the same quality that TOTO is known for, the C100 Washlet is packed with features such as front and rear washing, air dry, deodorizer and premist. Unlike the higher end TOTO washlets, the C100 comes in both the elongated and round sizes; it is also available in either cotton white or sedona beige colors. It is powered by an attached side panel with easy to use button controls.  

The TOTO C100 fits 2 piece toilets and is available in ROUND and ELONGATED sizes.

The TOTO C100 washlet is TOTO’s most popular entry level bidet seat that features a side panel instead of a remote control.  Similar to the C200, the C100 is a well priced bidet seat with quality features and functions.  The TOTO C100 uses a tank-type heating system. This means that it has a pre-heated reservoir of warm water stored internally.  This pre-heated supply will last around 35-40 seconds during each wash before the spray starts turning cooler. The good thing is that the spray never gets completely cold either.

The TOTO C100 features two distinct rear wash modes, soft and hard.  The soft rear wash is a gentle spray with little aeration.  The hard rear wash adds air power that results in narrower, but firmer spray for users that prefer more power.  The feminine spray offers a gentler spray with a wider spray pattern and the nozzle can be oscillated back and forth.

The PREMIST feature for the C100 is unique to TOTO washlets. PREMIST lays down a fine layer of mist on your toilet bowl when you sit down. This mist of water inside your toilet bowl creates a slick surface that helps waste from sticking to your toilet. 

Like most TOTO washlets, the C100’s warm air dryer is above average. Bidet seats typically do not have strong dryers for hygiene reasons as you don’t want a strong fan blowing around your dirty toilet bowl. The TOTO C100’s above average dryer seems to move more air than other brands.


The TOTO C100 and C200 are almost identical. The main differences between the two bidet seats are as follows:

  • C100 (Side Panel), C200 (Mountable Wireless Remote)
  • C100 has 3 temperature levels for water, seat, and dryer, C200 has 5 temperature levels
  • C100 does not have any user presets while the C200 has 2 user profiles
  • C100 does not have the pulsating feature while the C200 does

The best invention since sliced bread!

This company added my discount after I put in the order and it arrived ahead of schedule. Good company. I would do business with them again.

Ronda Perry

Works great!

Fast delivery

I previously owned one from the bio bidet, which stopped working after two years.
This was the best deal for this Toto.
I’m pleased with the product.
Much better than bio bidet and keep our toilet clean.

Chris M
Great Bidet for a great price

This bidet is great on features and really easy to install. The water is warm and pleasant and the oscillating function is really nice to make sure you're completely clean. The heated seat has also been a lot more enjoyable than I expected, and the deodorizer works really well.

5 Stars

Good experience! I will buy again from Bidet King.
