Frequently Asked Questions
• Do the new S5 washlets really have unlimited warm water?
Yes, the new Washlet S5 employs an instantaneous heater. That's the main upgrade over the older C5 model, which utilized a tank heater.
• Is the Washlet S5 worth it over S2?
If you value a wall-mounted remote, 4 user presets, and a night light, the S5 is the easy pick; cleansing performance is excellent in both. The S5 also has a seamless design, making it easier to clean.
• Is the S5 actually replacing the C5? Should I still buy a C5?
TOTO had transitioned from C5 to S5 in 2025. The S5's continuous endless warm water, remote with presets, and updated design make it the safer long-term choice.
• Will it fit my toilet?
This Washlet S5 will fit most elongated North American toilets. An elongated toilet’s bowl is 18.5 inches from the mounting holes to the front of the bowl.
• How do I install the S5? Is it DIY or do I need a plumber?
Most people are able to do it themselves. The project involves attaching the seat, connecting the water line, and plugging it into an electrical outlet, so make sure you have one. It comes with a step-by-step illustrated guide.
The TOTO Washlet S5 Elongated Electric Bidet toilet seat with Instantaneous Water Heating and Premist delivers ecology-minded luxury with a streamlined design. Unlike traditional Toilet paper that can often be rough and ineffective, the Washlet quickly provides endless comfortable warm water cleansing at the touch of a button.
*Please note - this S5 Washlet is designed to fit ELONGATED toilets only! For ROUNDED toilets – please see model SW3445#01.
Part of the newly redesigned S series, the Washlet S5 is fully automated, featuring an illuminating night light and a soft rear spray, rear cleanse, and front cleanse with the option of an oscillating or pulsating stream. The controls are located on a slim, wireless remote. Premist wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean.
The S5 model utilizes TOTO's eWater+ system when the wand self-cleans. eWater+ transforms the water into a safe and powerful compound, creating peace of mind by cleaning the inside and outside of the wand before and after every use.
The S5 Washlet features a heated SoftClose seat with five temperature settings, an air deodorizer, and a warm air dryer with five temperature settings. Using a Washlet reduces the need for Toilet paper, saving trees and water used to manufacture each roll. As we get older, reduced mobility, medical conditions, and debilitating illnesses can make it increasingly hard to clean ourselves after using the toilet. With a Washlet, just the touch of a button can leave you feeling clean and refreshed.
Easy to install and includes mounting and connection hardware.
