## Description

A lot of life happens in the bathroom. So at TOTO, we design simple, brilliant, elegant solutions for basic human needs. Every TOTO innovation has a single motivation: helping people feel cleaner and more alive.

Review: This was an exact fit - Customer had bought a new electric bidet but lost the fitting. This was the exact fit replacement!
Review: As expected but difficult to install for a wall hung toilet - The product is very good. But we have a wall hung toilet, meaning the water tank is inside the wall. There were no installation instructions for this type of toilet and it turned out to be complicated. There was a YouTube video showing how to install which was helpful. A plumber was definitely required.

## Customer Reviews

### ⭐⭐⭐⭐⭐ This was an exact fit
*by T***N on September 28, 2024*

Customer had bought a new electric bidet but lost the fitting. This was the exact fit replacement!

### ⭐⭐⭐⭐ As expected but difficult to install for a wall hung toilet
*by S***E on March 28, 2026*

The product is very good. But we have a wall hung toilet, meaning the water tank is inside the wall. There were no installation instructions for this type of toilet and it turned out to be complicated. There was a YouTube video showing how to install which was helpful. A plumber was definitely required.

### ⭐⭐⭐ Non-industry standard sizing
*by U***C on December 15, 2025*

While I have had no issues with this part, it is very frustrating that Toto is taking advantage of people. This product is completely over-priced because they are using a non-industry standard size. In my opinion, this part should have been included with my Toto seat that I purchased, ridiculous that this is sold separately and there was no way to use the seat without coming here to buy the additional part.
