Electronic Bidet Seats: Fitment Guide

Use the guide below to determine if your toilet is compatible with bidet seats.  The guide will also help you decide whether your toilet bowl shape is round or elongated.

 

Ok, so I want to buy a bidet toilet seat. Where do I start? 

Great! Glad to hear you enjoy feeling clean and are ready to upgrade your throne with a bidet toilet seat.  First, you need to determine what type of toilet you currently have (or whatever toilet you wish to equip).  Toilets come in two basic form factors: the standard 2pc with separate tank and bowl, or the more modern 1pc sculpted unit.


1pc

1 PIECE TOILET
A toilet sculpted into a seamless unit, and has no crevices between the tank and bowl.

2pc


2 PIECE TOILET
This type of toilet has a separate tank and bowl which are bolted together upon installation

 

Got it. So what does it mean if I have a 1pc or 2pc toilet? 

2 Piece Toilets - You're in luck. Virtually all bidet toilet seats will be able to fit. You simply need to decide whether your bowl is round or elongated.

1 Piece Toilets - Your selection is a bit more limited.  Depending on the actual shape of your 1 piece toilet, a bidet seat may or may not fit. If you're not sure, simply give us a call, or email us a picture of your toilet at support@bidetking.com - we're here to help. 


If the bowl remains relatively flat and meets the toilet tank at close to a 90 degree angle, a bidet seat should be able to fit. 

1 Piece toilets like the TOTO Ultramax or the Kohler Memoirs are great examples. 

1 piece ok                   

If the tank is curved and meets the bowl on a slope (known as a "french curve") then it is unlikely our bidet seats will fit. 

The Kohler Rialto and San Raphael are popular examples.

NOTE: The INAX Luscence is the only bidet that will fit this style toilet.

How do I measure my toilet to determine if I have a Round or Elongated bowl?

After you figure out whether you have a 1pc or 2pc toilet, the next step is to determine if your toilet bowl shape is Round or Elongated.  Many of the more modern toilet bowls in the US have the Elongated shape.  Measure your toilet in inches according to the guide below:

 

toilet dimensions

Line A: Bidet seats need a minimum of 1.5" of clearance from the center of the toilet seat bolt holes, to the front of the toilet tank.  

Line B: The distance between the centers of the bolts holes should be between 5" and 7.5"

Line C: Elongated bowls have a measurement greater than 18" from the center of the bolt holes to the front of the bowl.  Round bowls have a shorter measurement, usually between 16" and 17.5".

Again, if you're not sure, simply give us a call, or email us a picture of your toilet at support@bidetking.com - we're here to help.
