  • The longest drain channel currently available is 72" but you are not limited to pan sizes 72" wide. You can purchase additional pan sloped panels and create for example a 120" x 120" layout.
  • 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)
  • For any larger shower floor layouts that have sloped floor beyond 6 feet any direction from the drain, you will receive and use additional Panel C components and shim each successive one 3/8" as needed.
  • When choosing NO PAN option when planning to dry-pack mud the sloped floor, the kit comes with a base 216 SF of WP membrane and 66 LF of WP seaming band typically suitable for up to 72x72 layouts. For larger layouts, be sure to order additional WP and band material.
  • Do not choose a channel drain length larger than your chosen pan size unless you plan to dry-pack fill in a larger size to accommodate the longer channel. For example, if the maximum size of your pan area is 60" x 60", be sure to choose a 50" or 60" channel, not a 72".
  • 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.
