Fit and Compatibility Requirements
Our Swash bidets are compatible with most Standard toilets on the market. However, certain parameters must be met for a successful and compatible installation! Please review the appropriate guide below to find out if your toilet is compatible with our products!

Swash Bidet Fit & Measurement Guide
Step 1: Measure the distance between the bolt holes
The space must be between 5-1/4 inches and 8 inches.
Important Note: To properly fit SE400, SE600, IS707, CL510, and CL950 models, this distance must be exactly 5-1/2 inches.
Step 2: Measure the distance from the center of the bolt holes to the toilet tank
To ensure proper clearance, there must be at least 1½ inches of clearance from the bolt holes to the toilet's water tank. Please note, that if your water tank is angled or has a protruding cover, this may interfere with the installation of the product.
If the distance from the center of the bolt holes to the toilet tank is less than 2 inches, the Swash may extend slightly over the front edge of your toilet bowl.
Step 3: Determine Toilet Size
To ensure you purchase the correct size for your toilet, please measure the distance from the bolt holes to the front of the toilet bowl to determine if you have a round or elongated fixture.
- If your measurement is 18" – 19½" order an Elongated Swash
- If your measurement is 16" – 17¾" order a Round Swash
Please note: Some toilets may require an Alternative T-Valve and/or Top Mount Hardware.
Step 4: Confirm Available Clearance
To ensure 100% compatibility, please measure the distance from the front of the toilet tank to the front of the toilet bowl.
If this measurement is less than 20½ inches, consider purchasing a Round size to reduce the amount the seat extends over the front edge, even if your fixture is elongated.
The overall length of the Round Swash is 19.4 inches. A distance less than 19.4 inches from the tank to the front of the toilet bowl will also cause overhang.
SpaSuite Attachment Fit & Measurement Guide
Our SpaSuite bidet attachments fit nearly all standard Round and Elongated toilet bowls, including most one-piece and curved toilet fixtures (commonly referred to as French Curve). Refer to the fit diagram below for exact specifications for fitting the bidet attachment to your fixture.
Standard Fixtures
Bolt holes must be between 5-1/4 inches and 8 inches apart. You will also need at least 3/4 inch clearance from the center of the bolt holes to the back of the toilet tank.
Fixtures with Curved Tanks (French Curve Fixtures)
- Measure 2-1/4 inches in a straight line from the center of either bolt hole to the edge of the toilet fixture (shown as A in the diagram below).
- Measure from Point A (established in the step above) towards the toilet tank. You will need at least 3/4" of clearance (shown as B in the diagram below) in order for the SpaSuite products to fit on your toilet.
Lumawarm Fit & Measurement Guide
The LumaWarm heated toilet seat fits most standard Round and Elongated toilet bowls. Refer to the fit diagram below for exact specifications for fitting the bidet attachment to your fixture.
The measurement between the 2 bolt holes (bolt spread) must be the standard US size of 5-1/2 inches or the European size of 6-1/4 inches for the Lumawarm seat to mount properly.
Important Note: The LumaWarm is not compatible with toilet seat risers. However, we do sell top-mount hardware separately here.

Toilet Compatibility Guide
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, use the toilet manufacturer’s spec sheet and the diagram below to calculate whether it is compatible. If the value of “D” is greater than 1-1/2 inches, the toilet is compatible with your Swash.
Important Note: Not all toilet manufacturers document these measurements. Please contact your toilet's manufacturer for detailed measurements if you are unable to measure yourself.
If you’re looking for inspiration for your new toilet, our “Best Of” list is below for your reference.
