Swash 300-900-1000 Toilet Fit Guide

The Brondell Swash 300, 900, and 1000 bidet seats fit most residential toilets, including many contoured one-piece fixtures. Unless you have a toilet with a square bowl or unusual shape, these Swash models should fit your toilet.

To confirm, please follow the steps below:

  1. View our Swash fit diagram above or you can download and print it by clicking here (Adobe PDF).
  2. Measure the distance from the bolt holes to the front of the toilet bowl to determine if you have a round or elongated fixture.
  3. Measure the distance between your mounting bolt holes to ensure the space is between 5-1/4” and 8”.
  4. Lastly, measure the distance from the center of the bolt holes to the toilet tank to determine proper clearance.  The toilet will need at least 1-1/2” inches of clearance.

Please note: if the distance measured from the center of the bolt holes to the toilet tank is less than 2”, the front end of the Swash may slightly extend over the front edge of your toilet bowl as there may not be enough room to slide the seat all the way back to the tank. If this is the case, it might be helpful to measure from the tank of the toilet to the front of the bowl.  If this dimension is less than 20.5”, consider purchasing the Round size to reduce the amount that the Swash seat extendeds over the front of the toilet bowl.

Swash 300, 900, and 1000 models will not install the Kohler Santa Rosa, Kohler Rosario, Kohler San Martine, or the Kohler San Rafael.  The Kohler Rialto works on a case by case basis, based on the success of the measurements noted above.

Swash Fit Diagram for New Toilets

If you’ve decided you’d like to install the Brondell Swash on a new toilet, we recommend you find a toilet that matches your size, budget, design, performance, and height requirements.  Once you find your toilet, check the Swash 300, 900, and 1000 Fit Compatibility List by Toilet Manufacturer to ensure it’s compatible. Some toilets listed note they require an alternate t-valve and/or top mount hardware, found here.

Please note, though we try our hardest to keep this list up to date with new toilets, your toilet might not be listed.

Simply view the Spec sheet provided by the toilet manufacturer, and using the diagram above as a guide do the following calculations:

  1. Measure the the overall length of the toilet (A).
  2. Subtract the depth of the toilet bowl (B) and the depth of the toilet tank (C) from A. This determines the clearance for the bidet seat (D).
  3. If the clearance (D) is greater than 1-1/2”, the toilet is compatible with Swash models 300, 900, and 1000.
