Kirb-Perfect® is a stay-in plastic form designed to eliminate the possibility of any nails puncturing the liner on the top or inside walls of shower curbs.

Kirb-Perfect® is attached to the outside wall only, eliminating any water intrusion to the stacked 2x4’s that creates the curb.

• Top has built-in pitch into shower.
• Can be used with or without the presence of wood.
• Preserves the integrity of the liner.
• Provides a cement backing for ceramic, porcelain or stone.
