Concrete isn’t just for industrial spaces — it’s one of the most stylish and practical choices for modern wet rooms. Whether you’re building a spa-style ensuite or upgrading a family bathroom, concrete wet room floors deliver a seamless finish that’s waterproof, easy to clean, and visually striking. No grout lines, no lifting tiles — just solid, functional beauty.
| Material | Seamless | Slip Resistance |
|---|---|---|
| Polished Concrete | Yes | Medium (can be upgraded) |
| Micro-Concrete | Yes | High |
| Tiles | No (grout lines) | Varies by tile |
| Vinyl / LVT | Yes (sheet types) | High |
More designers and builders are moving away from tile — and here’s why.
When properly sealed and installed with tanking membranes, concrete finishes create a 100% waterproof wet room — with no vulnerable joints or seams like traditional tile layouts.
Smooth, uniform floors with no breaks create a calming, high-end spa feel. Concrete pairs well with timber, brass, black fixtures, and neutral palettes — perfect for timeless design.
Concrete finishes can be treated with slip-resistant coatings — ideal for barefoot use. They also work brilliantly with underfloor heating, holding warmth and drying quickly after showers.
The process begins with a full assessment of the existing floor. Wet rooms can be built over concrete slabs, screeds, tile, or timber — but each requires a different prep method. We check for movement, moisture, and surface contamination. For timber floors, strengthening may be needed to prevent flex. If the surface is tiled, it can sometimes be primed over. On bare concrete, we’ll mechanically grind and clean to remove sealers, laitance, and dust. This ensures proper bonding later. Proper preparation is the foundation of a successful wet room — skip this, and problems are inevitable down the line.
Once the substrate is ready, we install a full wet room tanking system. This creates a waterproof membrane that covers the entire floor and returns up the walls, protecting the structure from leaks. A drain tray is set in place — either a linear (channel) drain or a central point drain — and the floor is built up with a slope (fall) toward it. This fall is essential for proper drainage without puddling. Drainage design must also account for any underfloor heating, plumbing runs, or floor height transitions into adjoining rooms.
With the tanked area and falls ready, we install the concrete finish. If you’re using polished concrete, we’ll pour or grind the existing slab, then polish it through progressive grit stages. For micro-concrete, we trowel on thin, layered coats to achieve the desired texture and colour. This material wraps easily around curves and edges, creating a unified look with floor-to-wall continuity. Colour can be embedded in the mix or added as a wash layer. Each system is designed for wet area durability, so it remains bonded, even in high-humidity conditions.
The final step is sealing the floor for waterproofing and protection. Depending on the system, we use breathable polyurethane, epoxy, or specialist wet-area sealers. These prevent water penetration while allowing moisture to escape from the substrate if needed. We also add anti-slip agents if required — especially near showers or bath areas. Curing time varies by product but typically takes 24–72 hours. After that, your concrete wet room floor is ready for full use — with no tiles, no grout, and no fuss.
