Why Bathroom Tiles Make Such a Big Difference
Tiles are one of the most impactful elements in any bathroom. They set the tone for the entire space — whether you're going for a clean, modern look with large-format porcelain, a timeless classic with white subway tiles, or a bold statement with patterned encaustic tiles. Getting your tile choice and installation right pays dividends for years.
Choosing the Right Tile
Material Matters
| Tile Type | Best For | Key Consideration |
|---|---|---|
| Ceramic | Wall tiles, low-traffic areas | Affordable but less durable than porcelain |
| Porcelain | Floors and walls | Dense, water-resistant, very durable |
| Natural Stone | Feature walls, luxury finishes | Requires sealing; can be slippery when wet |
| Glass | Backsplashes, shower accents | Visually striking but shows water marks |
| Encaustic/Cement | Feature floors | Distinctive patterns; needs regular sealing |
Slip Resistance for Floors
Always check the slip resistance rating (PEI rating or R-value) for any tile intended for the floor. Polished tiles that look beautiful on walls can be dangerously slippery underfoot when wet. Aim for a PEI rating of 3 or above for bathroom floors, and choose tiles with some texture or a matte finish.
Tile Size and Room Proportion
Large-format tiles (600mm×600mm and above) can make a small bathroom feel more spacious because they create fewer grout lines. Smaller mosaic tiles work well in wet zones and on curved surfaces. Match tile scale to the room size — very large tiles can overwhelm a tiny cloakroom.
Preparing Your Bathroom for Tiling
Good preparation is what separates a lasting tile job from one that fails within a few years.
- Check your substrate. Tiles need a solid, flat, moisture-resistant base. Use tile backer board in wet areas — standard plasterboard is not suitable behind a shower.
- Fix any movement. Tiles crack when the surface beneath them moves. Ensure floors are solid and walls are secure before you start.
- Remove old tiles carefully. Use a chisel and hammer, working at a low angle. Protect plumbing and fixtures with sheeting.
- Level and prime. Fill any dips or holes with a suitable filler, allow to dry, and apply a tile primer to improve adhesion.
Tiling: Key Techniques
- Find your centre point. Start tiling from the centre of the wall or floor and work outward so cuts are symmetrical at the edges.
- Use spacers. Consistent grout joints look professional and allow for slight movement. Spacers make this effortless.
- Back-butter large tiles. Apply adhesive to both the substrate and the back of larger tiles to ensure full coverage and a solid bond.
- Check for level constantly. Use a spirit level every few tiles — one crooked tile early on can throw off an entire wall.
Grouting and Sealing
Allow adhesive to cure for at least 24 hours before grouting. Mix grout to a smooth, lump-free consistency and work it into joints with a float, removing excess with a damp sponge before it dries. Once grout is fully cured (typically 48–72 hours), apply a grout sealer in wet areas to resist staining and mould growth.
Common Mistakes to Avoid
- Skipping the waterproofing membrane in shower enclosures
- Using wall adhesive on floors (always use floor-rated adhesive)
- Not buying enough tiles — always order 10–15% extra for cuts and breakages
- Rushing grout joints before adhesive has fully cured
A well-tiled bathroom is a genuine investment in your home. Take the time to plan, prepare properly, and the result will look professional and last for decades.
