Kirb-Perfect is now available! Now you can quickly and easily build your shower curbs without the need for backerboard or wire lath. Kirb-Perfect creates a professional curb while saving you time and money.

Kirb Perfect Facts:

  • Top has built in pitch into shower.

  • Can be used with or without the presence of wood.

  • Preserves the integrity of the liner.

  • Simple to add lightweight mud to both sides of the pan material.

  • Provides a cement backing for ceramic, porcelain or stone

Kirb-Perfect was designed to eliminate the need to attach cementatious backer board or wire lath to a vinyl wrapped, 2x4 stacked shower curb.

Kirb-Perfect will not puncture the top or inside of the pan membrane, thus reducing the risk of leakage and preserving the integrity of the liner.

Secured with nails on the outside wall of the curb is sufficient to hold Kirb-Perfect in place.
Also, Kirb-Perfect can be used without the presence of wood altogether; it will stand with the vinyl liner held up in the center of the cage, making it simple to add a light weight mud to both sides of the pan material while filling.

The top panel is then attached using the stainless screws provided. Kirb-Perfect is then screeded full to provide a cement backing on which to adhere ceramic, porcelain or stone tile.

The Kirb-Perfect Shower Curb is a stay-in-place plastic form for building perfect shower curbs.Kirb-Perfect is designed to be used with a pan liner

It can be used with or without a 2 x 4 wood curb. With molded in dovetail connecting lugs, this curb can be used for multiple length installations.

Each piece of the Kirb-Perfect Shower Curb is easily cut with a hacksaw, PVC cutters or angle grinder. Supplied with two (1-1/4" long) and eight (3/4" long) stainless steel self tapping screws and illustrated installation instructions.

Kirb-Perfect is 4-9/16" wide x 30" long and 5-1/2" high.
