Kirb-Perfect shower curb is a stay-in-place plastic form for building perfect shower curbs. The assembled Kirb slides over 2 or 3 stacked, 40 mil vinyl liner wrapped 2x4’s or 2x3's but can be used with all waterproofing methods. With molded-in dovetail connecting lugs, this curb can be used for unlimited, multiple-piece length installations. Each section of the Kirb-Perfect Shower Curb is easily cut to fit with a hacksaw, jigsaw, or an angle grinder.
  • Eliminates harmful puncturing of the liner, preserving liner integrity
  • Made with 20% fiberglass filled ABS for high strength and non-rotting qualities
  • Adjustable in height, length and width to accommodate straight and angled shower entrances
  • A Stay-in-Place form that creates a perfect shower curb with the code required top slope built-in



Narrow Kirb-Perfect Option


If a slimmer, more slender width curb entrace is desired, Kirb-Perfect can be customized to be 1 inch narrower than full width for use with 2x3’s instead of 2x4's.  Easy to follow instructions included
