Shower Bases & Waterproofing Kits

A shower waterproofing kit usually includes the essentials needed to create a watertight barrier before tiling, such as waterproof membrane, sealing tape, internal corner pieces and adhesive or liquid waterproofing compound. Contents can vary by product, so it is always worth checking whether the kit is designed for walls, floors or full wet room installation.

In most bathroom installations, yes. A shower base manages water drainage, but a waterproofing kit helps protect the surrounding walls, joints and floor areas from moisture penetration. Using both together is a sensible way to reduce the risk of leaks, mould and damage behind tiles.

Start by measuring the available space carefully, including wall-to-wall dimensions and door clearance. You should also consider the shape of your enclosure, the position of the waste outlet and whether you want a low-profile or raised design. Choosing the correct size ensures a better fit and a more straightforward installation.

Many shower waterproofing kits are suitable for wet rooms, but it depends on the specific product and the level of coverage required. Wet rooms need thorough waterproofing across floors and often walls as well, so it is important to choose a kit specifically intended for wet area or wet room use and follow the installation guidance closely.
