Frequently Asked Questions (FAQs)

1. Can you use a bidet on a one piece toilet?

However, some one piece toilets have very limited space in the back where the seat connects to the toilet, which makes fitting a bidet seat on them a bit tricky. If you already have a one piece toilet in your home, and you're looking to install a bidet seat on it, go for it!

2. What is the difference between a washlet and a bidet?

Bidets are separate fixtures typically installed next to the toilet, with a standard faucet; washlets are seats that fit on top of a toilet bowl and often have several cleaning options and other features.

3. Will washlet fit my toilet?

WASHLETs will fit most standard North American toilets. To see if a WASHLET will fit on your toilet, follow these simple steps: First, determine if you have an elongated or round-front toilet. An elongated toilet's bowl is 18.5 inches from the mounting holes to the front of the bowl, while a round front is 16.5 inches.

4. What is the difference between a toilet and a washlet?

A washlet is a high-tech toilet seat with a water hook-up and spray nozzle in the back. Since it is basically a replacement to a regular toilet seat, there is no extra cleaning and it does not take up any extra space in the bathroom.
