A pre-formed polyurethane shower hob, 1200mm x 75mm x 50mm, that replaces the old timber-and-screed hob build. Light enough to carry one-handed, cut with a hand saw, and ready for waterproofing membrane straight after fixing.
Fix it to the slab, corner-seal it, and membrane over it. No rot, no swelling, no waiting for timber framing to be built level.
Frequently asked questions
How should the subfloor be prepared for this hob?
Level the subfloor using a tile screed or leveller to ensure full, even contact with the hob. Minor adjustments can be made with shims if necessary to achieve a stable base.
Can this hob be used for all wet area applications?
This hob is designed for perimeter barriers in wet areas like showers. It requires full waterproofing prior to tiling and is not intended for structural load-bearing applications.
Is this hob compatible with waterproofing membranes?
Yes, it works with both liquid-applied and sheet waterproofing systems. Ensure the hob surface is clean and dry before membrane application for optimal adhesion.
What is the best way to cut the polyurethane hob?
Use a fine-toothed handsaw or a power saw with a clean blade for precise cuts. Mark your measurements clearly before cutting to ensure accuracy and reduce waste.
Substrate guide
Proper substrate preparation ensures a stable foundation for the hob and reliable performance of the overall waterproofing system.
Concrete floors
Surface prep: Ensure the surface is clean, dry, and free from contaminants. Level any significant unevenness using screed or leveller. If required by the chosen adhesive, prime the concrete surface.
Primer: Optional, based on adhesive selection.
Compressed fibre cement
Surface prep: Ensure the surface is clean, dry, and stable. Verify a strong mechanical bond can be achieved with the chosen adhesive.
Primer: Optional, based on adhesive selection.
Timber substrates
Surface prep: Install over a waterproof board or screed system to provide a stable, moisture-resistant base. Ensure the underlying timber is structurally sound and prepared according to the board or screed manufacturer's specifications.
Primer: Not required for the hob itself when installed over a prepared waterproof board or screed. Adhesion will be to the board or screed system.
