Tiles 101: Choosing the Right Tile for Every Part of Your Bathroom

Tile choice shapes your bathroom's look more than almost any other decision, but it's also a functional one. The wrong tile underfoot can be genuinely dangerous when wet, and the wrong tile in a shower recess can shorten the life of your waterproofing. Here's a practical, no-jargon guide to picking the right tile for each part of the room.

The Main Tile Types

Porcelain

Porcelain is the workhorse of modern bathroom renovations, and for good reason. It's fired at a higher temperature than standard ceramic, which makes it denser, less porous and more resistant to water absorption, staining and chipping. It's available in an enormous range of finishes, including convincing timber-look and stone-look styles. For most Melbourne bathrooms, porcelain is the safest all-round choice for floors, walls and shower recesses alike.

Ceramic

Ceramic tiles are typically more budget-friendly than porcelain and work well on walls, where they don't need to withstand foot traffic or heavy moisture cycling. They're softer and slightly more porous, so they're generally not recommended for bathroom floors, particularly in wet areas, where they wear faster and can be more prone to cracking.

Natural Stone

Marble, travertine and limestone bring a genuine luxury feel that's hard to replicate with a printed finish. The trade-off is maintenance — natural stone is porous and needs to be sealed on installation and resealed periodically to resist staining and water damage. It also tends to sit at a higher price point. Stone works beautifully as a feature wall, a niche lining or a vanity splashback, and can be used on floors provided it's honed or textured for slip resistance and properly sealed.

Large-Format Tiles

Large-format tiles (typically anything over 600mm on one side) have become a signature look in contemporary Melbourne bathrooms. Fewer grout lines mean a cleaner, more expansive appearance and less grout to clean over time. They do require a highly skilled installer and a very flat, well-prepared substrate — an uneven surface will show under a large tile far more obviously than under a small one, so installation quality matters even more than usual.

Mosaic

Small-format mosaic tiles, whether glass, stone or porcelain, are ideal for areas with curves, slopes or tight geometry — think shower floors with a fall to the drain, niches, and feature strips. Their many grout lines actually work in their favour underfoot, adding grip, which is why mosaic remains a popular, practical choice for shower bases even in otherwise large-format bathrooms.

Understanding Slip Ratings

Slip resistance is measured in Australia using the R-rating system (from wet-pendulum and ramp testing), and it matters far more than most homeowners realise until they're standing on a wet floor in socks. For a domestic bathroom floor, look for a minimum of R10, and consider R11 for shower floors and any area that gets consistently wet, such as in front of the shower screen or bath. Glossy, highly polished tiles look striking but are rarely appropriate for bathroom floors — save the high-gloss finishes for walls, where slip rating is irrelevant.

• Bathroom floor (general): R10 minimum
• Shower floor / wet zone: R11, often in a smaller mosaic format for drainage falls
• Walls: no slip rating required — choose on look, size and budget

Matching Tiles to Each Zone

Floors

Prioritise slip resistance first, style second. Porcelain in a matte or textured finish, at R10 or above, is the reliable default for the main bathroom floor.

Walls

This is where you can take more creative risks — gloss finishes, natural stone, bold colour or pattern, and large-format slabs all work well since walls don't carry the same slip and wear demands as floors.

Shower recess and floor

Choose a tile rated for wet, high-traffic use. Mosaic or small-format porcelain at R11 handles the shower floor and its drainage fall well, while larger porcelain tiles are fine on shower walls provided the waterproofing membrane beneath is installed correctly.

A Note on Grout and Waterproofing

Even the best tile is only as good as what's underneath it. Poor waterproofing or grout work is behind most bathroom leaks, and repairs down the track typically run $1,500–$8,000 depending on the extent of the damage — far more than the cost of doing it properly the first time. Whatever tile you choose, make sure it's installed by a licensed tradesperson over a correctly detailed waterproofing membrane, with a workmanship warranty behind it.
