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.

  1. 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.
  2. Fix any movement. Tiles crack when the surface beneath them moves. Ensure floors are solid and walls are secure before you start.
  3. Remove old tiles carefully. Use a chisel and hammer, working at a low angle. Protect plumbing and fixtures with sheeting.
  4. 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.
