Adjusting Your Kirb Perfect

How To Adjust Your Shower Curb When Installing the Pan Liner

Adjusting a OneLiner size using only the Kirb Perfect Kit

 Note: Reduce the size up to 3 ¾", as long as one full side of your shower is all curb.

Step 1:

Determine the depth of shower that will work in your bathroom. Choose the size of OneLiner that is no more that 4" wider than that.

 Example:

42"x42" OneLiner with the typical 3 stacked 2x4s for under the Kirb Perfect Kit. Actual overall size of shower with 2x4 curb outside OneLiner is 42" x 46"

Step 2:

Cut OneLiner side wall down to 4"-4 ½" in height.

Example: 

Place the Kirb wherever you need to along one full side of the OneLiner:

  • Have the OneLiner right in the middle of the Kirb Perfect Kit, or
  • Have the whole Kirb Perfect Kit inside the OneLiner.

Whatever you need to make the perfect shower depth for your application!

  

Step 3:

Use Quick Clips to attach Kirb Perfect Kit in place temporarily to floor on outside of OneLiner.

Example:

This will keep your Kirb Perfect Kit in place while you fill the curb with mortar

 

Step 4:

Fill Kirb Perfect with mortar

   Example:

  1. Fill the body of the Kirb Perfect Kit with mortar (either 4:1 or 3:1 Sand:Cement Mix as per instructions),
  2. Screw the top plate in place and smooth out the top and sides.
  3. Let set for 24 hours.

Kirb Perfect is a stay in place form, no need to remove, just chisel off the Quick Clips on the bathroom floor, so they don't interfere with the floor to be installed.

 

A Standard OneLiner 42"x42" and traditional curb is 46" deep. By bringing the curb into the OneLiner, the depth is now a minimum of 42 ½" or anything in between! The depth of your shower is now unlimited!!!
