Linear drains bring a modern look to any shower they're installed in, and this 36" extension kit for the KOHLER 2-1/2" linear drain channel will allow your drain to go the distance in larger showers. This kit includes a 36" channel with adjustable subfloor brackets, allowing you to extend your existing linear shower drain channel from 60" to 96" long. This product is intended to be installed with the K-80646 linear shower drain.

  • Drain outlet location can be adjusted to bypass joints, venting, or other in-floor obstacles
  • Outlet adapter can be preattached to drain pipe for simplified installation and access to couplings
  • Easy-clean domed hair strainer prevents clogs
  • Subfloor brackets are height-adjustable to ensure the drain channel is mounted at the correct height during installation
  • Wide-top flange with protective film ensures excellent waterproof adhesion
  • Can also be installed with KOHLER side-outlet adapter K-28987 (sold separately)
  • Requires at least two Kohler 2-1/2" x 36", 2-1/2" x 48", or 2-1/2" x 60" linear drain grates to span desired final drain length
