Will a bidet fit your toilet?

Enter what you know. “Unsure” is better than a guess: the result will show which photo, measurement, or product drawing you still need.

1. What kind of toilet is it?
2. What is the bowl shape?
3. Add the three measurementsUse inches. Measure from the center of the seat mounting holes, not the back edge of the porcelain.

Open the illustrated measurement instructions.

4. Does the porcelain rise or slope behind the bolt holes?This is commonly called a French curve.
5. Is the toilet skirted or is the tank connection hidden?
6. Is a suitable outlet nearby?
7. Which category are you considering?

How to use the result

A green result means the broad category has no obvious universal blocker. It does not mean every model fits. A yellow result means the category may work but one or more exact-product drawings or installation details control. A red result means at least one broad requirement conflicts with your answers.

Do not buy from this screen alone. Save your measurements, identify the exact toilet model when possible, and compare the product installation drawing and return policy.
