The smarter way to waterproof a shower floor.

The MultiPanel Standard Shower Base Kit is an Australian-made, CodeMark-certified shower base solution designed to eliminate the cost, time and risk of traditional waterproofing methods. The fall is already graded into the base — no screeding, no liquid membrane, no waiting overnight. In most cases, you're ready to tile within the hour.

Manufactured from high-density polyurethane composite with a closed-cell structure, MultiPanel is 100% waterproof as a standalone product. It's lightweight, structurally sound, and compatible with standard tile adhesives and waterproof membranes.

Why Plumbers and Builders Choose MultiPanel

Traditional shower base systems require screeding, curing, liquid membrane application and drying time — adding days to a bathroom project. The MultiPanel Shower Base Kit removes that entirely. One trade, one session, tile-ready by lunch. That means fewer call-backs, faster handover, and a certified waterproof result every time.
