IS THE LINEAR DRAIN KIT INCLUED IN A LINEAR SHOWER KIT?

Yes! When you order a KBRS linear shower installation kit, you will be prompted to choose your linear drain style and finish that will fit with the provided slope in the kit.

WHAT TYPE OF THIN-SET SHOULD I USE?

Any quality "polymer modified" thin-set will do just fine. Do not use a premixed thin-set (i.e.... water already added). A premixed thin-set that comes in a bucket with water already added will not cure properly. Remember: No premix! Always add your own water! Different terms for modified thin-set include: modified thin-set, modified thin set with a latex additive, fortified thin-set, polymer modified thin-set, polymer fortified blended thin-set. The thin-set must meet or exceed ANSI A118.4 and ANSI Al18.11 requirements when mixed with water.

WHAT TROWEL SHOULD I USE?

In most cases, KBRS shower pan products include both a 3/4" U-Notched Trowel, and a 1/2" Square Notched Trowel. Which trowel you will need will depend on how high your drain is set "above" the sub-floor. Please refer to the guide below to determin which trowel to use for your shower installation.

3/4" U - NOTCHED
TROWEL

Drains 3/8" above the sub-floor, use the 3/4" U-Notched Trowel.

1/2" SQUARE NOTCHED
TROWEL

Drains 1/8" above the sub-floor, use the 1/2" Square Notched Trowel.

CAN THE LINEAR DRAIN BE INSTALLED WITH A MORTAR BED?

Yes, our linear shower drains can be installed with mortar beds. See below for things to keep in mind for mortar bed linear drain installations.

General Installation Considerations:

  • Linear drains are best placed against the end or side wall or shower threshold.
  • Any waterproofing layer should be supported by a pitched slope of 1/4” per foot towards the drain whether the waterproof membrane coat is under thick bed mortar or on top.
  • Reinforcing Fabric should always be used with Liquid Applied Membranes for gaps of more than 1/8”. It is recommended to use reinforcing fabric where the drain flange and mortar bed meet as well as for any floor to wall transitions for added durability.
  • If installing a curbless shower, position drain parallel to entry (front, middle or back of shower) so plank pitch doesn’t compromise an even/level entry.
  • If placing drain flush to walls - back and/or sides of flange should be set against the studs or sill plate (center of waste pipe needs to be 2 1/4” out) and backer board should be installed directly on top of flange.
  • Consider tile thickness and thin-set to make any needed adjustments. Finished wall tile should sit approximately 1/16” from the inside of the drain cavity wall to allow for proper grate placement.
  • Set floor tile 1/16” from the edge of the grate to allow for smooth installation and removal of grate.
  • Linear Drain Grate Risers (included with stainless steel grates) should be used to install the grate at the proper height, slightly below level of surface tile (approx. 1/16”) to ensure proper drainage.

WHAT COMES WITH THE LINEAR DRAIN KIT?

The linear drain kit includes a linear drain body, a linear grate (style of your choice), linear drain grate risers (with metal grates only), and a linear drain hair strainer.
