Polyurethane Shower Hobs are lightweight, preformed shower thresholds that provide a straight, consistent base for a tiled and waterproofed shower entry. Each hob measures 1200 × 75 × 50 mm and can be cut to length with a suitable saw, avoiding the time and moisture-related issues of building a traditional timber hob.
The rigid polyurethane profile gives the installer a clean edge to set out the shower threshold and integrate it into the bathroom waterproofing detail. It is useful for new bathrooms and renovations where a neat, repeatable hob is needed before tiling.
Installation essentials
- Cut the hob to suit the shower opening and set it on a sound, level substrate.
- Fix it using an adhesive compatible with both the hob and the underlying construction.
- Seal ends and junctions, then carry the specified waterproofing membrane continuously over the hob and adjoining floor and wall details before tiling.
The hob is not waterproofing on its own. It must be installed as part of a compliant, compatible wet-area system and is not intended as a structural load-bearing element. Confirm the membrane and fixing requirements for the project before installation.
What size is the polyurethane hob?
1200mm x 75mm x 50mm in the current product evidence.
Can it be cut to length?
Yes. It can be cut with a hand saw.
Is the hob itself the waterproof membrane?
No. It must be incorporated into the compatible waterproofing system.
Can waterproofing be applied after fixing?
Yes. Once securely fixed and detailed, the compatible membrane is applied over the hob and surrounding wet area.
- Prepared concrete wet-area floors.
- Compatible screed and wet-area floor build-ups.
- Other structurally sound shower-floor substrates approved for the complete waterproofing system.
