Toto Washlet Bidet Toilet Seat Review & Is it Worth the Money?
Bon Appetit

There’s been a lot of recent talk about the Toto Washlet Toilet and the strides it’s making in the smart home tech industry. We’ve installed this toilet in our customers’ homes quite a few times, and we feel it is worthy of a closer look.

The New C Series

TOTO is pleased to introduce the C2 and C5 TOTO Washlets, the next generation of the C series. The C2 and C5 washlets from worldwide bidet pioneer TOTO are new and upgraded versions of the famous C100 and C200 washlets. They have more modern looks and a few new functions than the previous version. Let’s have a closer look!

Product Specifications:

  • Dimensions: ‎20.88 x 15.06 x 5.81 inches
  • Weight: 14.92 pounds
  • Batteries: 2 AA batteries required
  • Shape: Oval
  • Color: Cotton White
  • Features: Heated, Bidet SeatRemote Control, Batteries, T-Connector, Instructions, & Installation Hardware


The TOTO C2 and C5 WASHLETS’ new, thinner shape produces a sleeker, more modern design. The older c100 and c200 models are substantially larger, standing nearly 7.5″ tall at the back. In comparison, the C2 and C5 are only 5.75″ tall in the back.

The C2 washlet has a redesigned side panel for improved usage and control. Also, the major function buttons are at the front, with large, easy-to-read buttons. The readability has improved over the previous C100 side panel. The temperature, deodorizer, energy savings, and other settings are located at the back of the side panel.

The C5 washlet comes with a wall-mountable, dual-sided wireless remote control resembling the design of the higher-end K and S series washlets. It is thinner and has greater contrast buttons for better readability than the preceding C200 remote. The fundamental wash actions, dryer, nozzle adjustments, and user preset buttons are located on the front of the remote. You can change the seat, water, air temperatures, automatic nozzle cleaning, and other fine-tuning options on the back.

The water supply hose and electricity cord are located on the left side of the seats. A deodorizer vent and the seat’s fast release tab can be found on the right.

The seat & lid are slow closing to prevent smashes. Simply pushing them forward will cause them to close softly on their own.


Adopting TOTO’s EWATER+ technology is the most significant functional difference between the earlier C100 and C200 models and the new C2 and C5. TOTO’s EWATER+ function electrolyzes ordinary tap water, transforming it into a disinfecting cleansing agent capable of sanitizing without the need for chemicals.

While prior versions lacked this feature, the C2 and C5 now disinfect the spray nozzle between uses with Ewater+ electrolyzed water.

Both new versions have a PRE-MIST function that sprays the toilet bowl with a fine mist before each use, which aids in the cleanliness of the toilet bowl.

Warm water, warm air dryer, oscillating nozzle, pulsating nozzle, environmental mode, nozzle sterilization, and automatic air deodorizer are all included in the C2, and C5 WASHLETS are all of the previous generation’s wonderful features.

Its warm water supply is limited, but the spray never becomes fully cold.

The new C2 and C5 washlets are welcome additions to TOTO’s renowned C series line. They add some practicality while also bringing the appearance up to par with current bidet seats.

What is a Smart Toilet Seat?

A smart toilet seat uses a combination of sensors and wireless technology to automatically flush and clean the toilet bowl for you. Some brands and models, such as the Toto Washlet Toilet S550e, even come with such advanced functions as opening and closing the lid for you. Toto smart toilets, in particular, are equipped with Tornado Flush Technology, which uses a water siphoning process to flush and clean the toilet more quickly.

Customers have really been enjoying the way the new Washlet toilet by Toto has been able to minimize manual cleaning efforts while maximizing the level of sanitation on a consistent basis.

eWater: A special kind of electrolyzed water which quickly disinfects and revitalizes your toilet bowl. This is the same kind of water used to disinfect food preparation products and cleaning supplies. It will pre-mist the bowl, wetting it before and after use. Each flush of the Toto toilet will mist the bowl with this special water again. This eliminates the need for chemically-toxic cleaning products.

Skirted Design: This design makes it easier for you to clean the toilet. It is a seamless and smooth shape from bowl to floor, without the traditional grooves and spaces that make it difficult to clean. Plus, it adds a touch of elegance to the style of your bathroom. It’s a great choice for a bathroom remodeling project.
