UHPC tiles for bathrooms and wet areas

Good practice in wet areas

• Install over a tested waterproofing system — tiles are not a waterproof membrane
• Specify a slip-resistant finish for floors and shower areas
• Seal according to the manufacturer's guidance for stain and limescale resistance
• Use compatible adhesives and grouts

Design ideas

Large-format UHPC wall slabs reduce grout lines for a near-seamless finish. Matching UHPC basins, vanity tops and shower trays from some manufacturers create a cohesive, monolithic look.

Showers and wet rooms

In showers and wet rooms, the floor needs falls to the drain and a slip-resistant finish. Linear drains work well with large-format UHPC tiles because they allow single-direction falls, avoiding awkward cuts. Use a tested tanking or waterproofing system beneath the tiles and seal joints and penetrations carefully.

Limescale and cleaning

In hard-water areas, limescale builds up on any shower surface. Avoid acidic descalers on UHPC, as acids can etch cementitious materials. Instead, use pH-neutral cleaners recommended by the manufacturer, squeegee surfaces after use and maintain the sealer to keep cleaning easy.

Spas and pools

In spas, saunas and pool halls, humidity, heat and chemicals add demands. Ask manufacturers about suitability for chlorinated or saltwater environments and any specific sealers needed. For pool surrounds, see our outdoor and pool page.

Seamless bathroom design

Using UHPC for floors, walls, vanity tops and basins gives a monolithic, spa-like look. Ask manufacturers whether they can colour-match tiles and cast elements, since separate products may otherwise vary in tone.
