Installation Sheet

Step 1 - Prepare Shower Pan

Pre-slope shower pan and install waterproofing

membrane per manufacturer’s instructions. Any

waterproofing membrane material or procedure

can be used (vinyl, CPE membrane, roll/paint on,

metal pan, hot mop, surface sheet membrane, etc.).

Perform a leak test as required.

Step 2 - Rough Opening

The Miseno Linear Drain channel width is 3-3/16”.

Confirm rough opening is approximately 2” wider

than drain length to accommodate backerboard and

wall tile thickness (a 38” rough opening will close

to almost a 36” finished opening based on the

thickness of materials).

Step 3 - Flexible Sealant Application #1

Cut a 2x4 to length for use as a placeholder for the

linear drain. This allows for a 1/8” gap around the

channel’s perimeter to apply a bead of flexible

sealant. Note: channel depths are 1-1/4” for the

Miseno tile insert linear drain and 3/4” for all

other Miseno linear drains.

Step 4 - Mortar Bed Installation

Using mortar, build up the shower base. Slope the

mortar creating a 1-2% grade toward the drain.

Allow the mortar to cure overnight before installing

tiles.

Step 5 - Tile Installation

using a thinnest mortar, install the floor tile and

entire shower alcove. Install tile into tile insert

tray (for tile insert drains only). Grout, clean and

seal all tile in the shower area.

Step 6 - Linear Drain Installation

Remove the 2x4, clean out the void and install the

Miseno Linear Drain channel as you would any tile

building up and supporting as necessary with mortar.

Ensure drain channel is level and just slightly below

(3/16” or less) the adjacent tile.

Step 7 - Flexible Sealant Application #2

Line perimeter of linear drain channel with a color-

matched flexible, waterproof sealant. This will allow

the stainless steel to expand and contract without

damaging grout or tiles.
