  • Pre-sloped pan panels have a 2 ft x 2 ft footprint each and come in a Panel A thickness 0.13 inch to 0.63 inch, Panel B thickness 0.63 inch to 1 inch and Panel C thickness 1 inch to 1.37 inch.(see diagram photo) However, none of the pan layout options for this kit require a Panel C.
  • All pan sections are trimmable and customizable for your unique layout. For the popular 3x5 bathtub space, you will use a 48x60 or 48x72 layout.
  • When choosing NO PAN option when planning to dry-pack mud the sloped floor, the kit comes with a base 108 SF of WP membrane and 33 LF of WP seaming band typically suitable for up to 32 x 60 or 48 x 48 layouts. For larger layouts, be sure to order additional WP and band material.
  • Many installers are installing these linear shower drain systems with a curb-less entry in mind (a primary reason for low-profile sloped pan sections.) These kits do not address curb options, so if you decide to implement traditional curb layouts. Please see the links for high-density polystyrene curb options if you want a curb and do not wish to build a curb substrate from lumber and board. Also, WP outside corners are recommended for integration of curb features in shower installations (see link.)
  • The seam band "flashing" that is included for your drain allows a transition flashing to permanently bond to your stainless steel drain flange. Do not attempt to bypass use of this component - the WP membrane will not reliably bond to stainless steel with thin-set mortar unless it overlaps/interfaces with the flashing. The flashing material itself bonds to the stainless steel with a very aggressive permanent butyl adhesive.
