Typical Installation Steps

  1. Construct shower surround in accordance with structural requirements leaving a penetration for drainage.
  2. Add a suitable drainage flange and fasten/bond in place and cap during the building phase. DrainTEK recommends using a suitable puddle flange with an internal diameter large enough for the shower grate outlet to fit loosely within.
  3. Complete water-proofing in accordance with AS3740 with waterproofing turned down into the plumbed drain.
    Note: Do not integrate tray with the water-proofing as steel expands/contracts differently to other materials.
  4. Adjust the height of adjustable puddle flange (if installed) to suit desired shower grate height If your tray outlet is not attached, then adhere with a waterproof adhesive sealant prior to installation and ensure it is secure.
  5. Set tray at required height in mortar so the finished tiles will be just above the top edge of the grate tray.

Lifetime Warranty

All drainTEK linear channels and grates come with a Lifetime Guarantee against manufacturing defects. Conditions may apply - see Renovator Store Warranty Terms and drainTEK Warranty Protection Page.
