Features of TOTO Washlet C100 Elongated Bidet Toilet Seat​

  • Washes with gentle, freshened warm water using a dual swinging action
  • Adjustable temperature and volume control
  • Includes automatic air deodorizer
  • Straightforward controls with side arm control panel
  • Includes quick-release plate for easier installation and cleanup
  • Heated seat function care of temperature control
  • Pre-mists water in the bowl prior to every use for better clean


Users can easily manage the water temperature so it will not be too cold or too warm for comfort. One smart feature is that the seat will remember the temperature you set for subsequent usage.

When it comes to its nozzles, the company actually makes the best ones for bidet seats. The wand comes packed with a lot of features for an item with such a simple design.

The wash is aerated moderately and it comes with adjustable temperature settings as well. This is a dual-action spray and it comes with oscillating abilities too.

The Pre-misting feature is a distinctive function that is not seen on many bidet toilet seats. It is an interesting concept and it should not be ignored by consumers.

What it does is it moistens the bowl as the user sits down on it. The Pre-mist stops feces from attaching itself to the sides of the bowl.

Hence this particularly helpful feature maintains a very clean toilet bowl at all times. It will also help you save time as you clean the toilet.

The seat remains heated all the time. Thus whenever you are not using the toilet, the seat remains warm, ready for use. Having a warm toilet seat though does not mean that it will consume lots of energy.

As soon as the bidet seat is done being used by the user, the unit switches to a lower power mode which in essence maintains the seat and the water in the tank warm whenever it is not being used.

The model comes with a user-friendly remote which is something all consumers will appreciate, regardless of age. It comes with the following functions:

  • Universal stop
  • Pressure adjustment
  • On and off options for soft rear oscillating and rear oscillating
  • Position adjustment
  • On and off settings for the dryer
  • Controls for a front wash

You will also see the temperature control located together with the dryer, water, and seat toggles. The last buttons on the panel are the energy-saving toggle and the wand-cleaning toggle.

This product is backed by a 1-year limited warranty. You have to keep in mind that several places might not accept returns since bidets are considered hygiene products.


While it is absolutely great that the product comes with a water warming feature, you have to be careful with the amount you use otherwise the water will run out. Furthermore, its accompanying T adapter is not suitable for regular US toilet filling valves.

While its threading matches US-made toilets, this does not mean that it will work as it should. This T adapter is not meant for beveled fittings in the States but for flat washer fitting only.


Despite its flaws, the​ TOTO Washlet C100 Elongated Bidet Toilet Seat​ is still a great buy if you are after a model that will further enhance your bathroom hygiene. Its Pre-misting feature is one advantage that you should check out.

Apart from that, having warm water and a heated seat all the time makes for a more comfortable toilet experience during the autumn and winter.

It is also great to have around in places that have frequent cold weather. Furthermore, it is easy to use so it is indeed a great recommendation for people who have never a tried bidet seat before.
