These instructions are for fitting a Swash bidet toilet seat onto an existing toilet.

How to measure for a Swash toilet seat

Measure the Bolt Hole Spread

Measure the distance between the bolt holes. The space must be between 5-1/4 inches and 8 inches.

Please note: to properly fit SE400, SE600, IS707, CL510, and CL950 models, this distance must be 5-1/2 inches.

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.*

Determine the Length of the Bowl

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.


* Is the distance from the center of the bolt holes to the toilet tank less than 2 inches?
The Swash may extend slightly over the front edge of your toilet bowl.

Seat Overhang

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.

FITTING A SWASH BIDET TOILET SEAT TO A NEW TOILET

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.

New Toilet Fit Guide

If you’re looking for inspiration for your new toilet, below is our “Best Of” list.
Please note, Brondell has not used any of these toilets and is not responsible for the performance of these toilets.  Brondell has no affiliation with the manufacturers listed below:

  • Best High End:  Toto Drake II Two-Piece toilet
  • Best High End Concealed Trap Away Toilet (Skirted):  Toto Legato One-Piece high-Efficiency*
  • Dual Flush High End:  Toto Connelly Close Coupled toilet, 1.28GPF & 0.9GPF
  • Dual Flush and Budget-Friendly: Glacier bay 1-piece High Efficiency Dual Flush Elongated Toilet in White
  • Wall-Hung:  Toto Maris (Because this toilet uses an In-Wall Tank System, your plumber will need to provide an accessible ½” water supply connection for the bidet)

 *you will need Alternative T-Valve and Top Mount Hardware for this installation

Bidet Attachment Toilet Fit Information

The PureSpa and FreshSpa lines of 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.

FreshSpa Toilet Fit Guide

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)

  1. 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).
  2. 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 PureSpa or FreshSpa to fit on your toilet.
