Bathroom Materials Popularity: What Australians Are Choosing Now — and the Practical Reasons Behind It
Ten years ago, the default residential bathroom floor was a 300×300 ceramic tile in a neutral colour. It showed up in renovation after renovation. Not because it was the best material for the job — but because it was available, affordable, and everyone knew how to install it.
That default has shifted. Porcelain now dominates wet area specifications across NSW and ACT. Large-format tiles are standard in mid-range and above renovations. Waterproof panels are taking share in investment properties. The shift happened for three overlapping reasons: expanded product availability, more consistent enforcement of compliance requirements under AS 4586, and the influence of renovation media pulling buyer preferences toward finishes that look distinctly different from what came before.
What follows is a reference guide to what’s being specified, what’s rising, what’s declining, and — critically — where popularity and practical suitability part company.
The Most Popular Bathroom Floor Materials
Floor tile decisions carry more compliance weight than wall tile decisions. Slip resistance classifications apply to what goes underfoot — particularly in wet areas — and the P-rating requirements under AS 4586 are a specification minimum, not a preference. That shapes what materials are actually appropriate, regardless of what’s on the mood board.
Porcelain has become the standard specification for good reasons. It handles the performance requirements of a wet area floor without the trade-offs that come with more porous materials.
Dense, low water absorption (typically below 0.5%), hard-wearing, available in formats from 200×200 mosaic to 1200mm+ slabs. The standard wet area floor specification in Australian residential renovations. Broad finish range — matte, textured, stone-look, polished — means design rarely forces a compromise on material. If someone is specifying something other than porcelain for a shower floor, there should be a clear reason why.
600×600 and above, increasingly up to 1200mm and beyond. Fewer grout lines, easier maintenance, and in smaller bathrooms the visual continuity makes the space read larger. The trade-off: requires a flatter substrate than standard formats (3mm over 3 metres for tiles 1200mm+) and back-buttering is mandatory under installation standards. Neither of those is optional. Both need to be in the quote.
Small-format mosaic — typically 25×25 to 100×100 — has returned as a feature accent rather than a primary floor tile. Used on shower floors where the joint frequency contributes to natural slip resistance and drainage, and in feature niches. Labour-intensive to install and to keep clean over large areas. Worth specifying deliberately rather than defaulting to it.

The Most Popular Bathroom Wall Materials
Wall tile specifications involve fewer compliance constraints than floor tiles — there is no P-rating requirement for a vertical surface — but the material and format choices have real downstream implications for installation time, grout maintenance, and long-term appearance.
Three categories dominate current residential specifications. Each has a different profile of cost, installation complexity, and maintenance commitment.

Natural Stone: Popular in Briefs, Less Common at Completion
Stone appears in more renovation mood boards than it appears in completed bathrooms. The gap between specification intent and installation reality is wider for stone than for any other material category.
The appeal is clear. Marble, travertine, and limestone have a quality and distinctiveness that porcelain stone-look tiles approximate but don’t replicate. For bathrooms where budget and maintenance commitment aren’t constraints, stone is a legitimate and durable choice.
What changes between the mood board and the quote stage: cost (supply runs higher than porcelain across all stone types, and installation labour sits at $80–$140/m² compared to $35–$75/m² for standard porcelain), the sealing requirement (before installation, during grouting, and on a regular schedule throughout the life of the bathroom), the substrate demands (heavier stone requires more robust preparation), and the cleaning restrictions (acidic products etch marble and travertine — a practical point that matters in a regularly used bathroom).
Stone makes sense when all of that is factored in. In an investment property with tenants who may not maintain it correctly, or a renovation on a timeline that doesn’t allow for proper substrate preparation, it’s a mismatch — not a material failure.

What’s Gaining Share in Australian Bathrooms
The materials and formats gaining market share in current renovation briefs share a common thread: the supply chain around them has matured. More experienced installers, better product availability, and more competitive pricing make them accessible at a wider range of budget levels than they were three or four years ago.
Fastest-growing category in investment and rental property renovations. No grout to maintain, faster installation than wet area tiling, and compliant in a shower enclosure when installed over correctly prepared substrate. Not a substitute for waterproofing — the membrane requirement under AS 3740 applies regardless of what goes on the wall above it.
1200mm and above, increasingly specified in mid-range and above renovations. Fewer grout lines, cleaner surface, and the supply chain now supports them at a broader price range. The requirements don’t change with popularity: substrate preparation to 3mm flatness over 3 metres, flexible adhesive, and back-buttering. Both must be in the quote.
Gaining share over polished across both floor and wall tiles. Two reasons: matte finishes more reliably achieve required P-ratings for floor tiles and are easier to clean consistently, and the look aligns with current renovation references. Stone-look porcelain in matte or honed finish is the current dominant specification in new renovation briefs.
Not real terrazzo — the look, achieved in porcelain. Real terrazzo is a poured material with specific substrate requirements and a price point that excludes most residential renovation budgets. Terrazzo-look porcelain delivers the aesthetic at a fraction of the cost and complexity. Growing rapidly in new bathroom briefs.
Relief profiles and 3D textured wall tiles are increasing in specification, driven largely by renovation media. Install complexity is higher than standard flat tiles — full adhesive coverage across an irregular surface is more demanding. Confirm installer experience with the specific format before specifying over a large wall area.
Rectified tiles — cut to precise dimensions after firing — allow grout joint widths of 1–2mm, producing a near-seamless surface. Increasingly specified as standard rather than premium. The requirement: substrate flatness must support the format. A 1mm joint on an unlevelled substrate produces an uneven result that no grouting skill can correct.
What’s Losing Share — and Why
Market share shifts in renovation materials are usually driven by supply chain changes, compliance tightening, or aesthetic cycles — not by the materials becoming objectively worse. Most of what’s declining is still a legitimate specification in the right context.
Subway tiles
Market saturation, not a product failure. The 75×150 subway tile in white or off-white has been the dominant feature wall tile in renovation briefs for close to a decade. It remains a practical, affordable specification. It’s losing share because it no longer reads as a design choice — it reads as a default. Still a fine tile.
Small mosaic as primary floor tile
The labour cost of installing 50×50 or smaller mosaic across an entire bathroom floor has become harder to justify against the outcome. As a feature element — shower floor, niche accent — it still appears regularly and works well. As the primary tile across a large floor area, the grout maintenance burden over the life of the bathroom is significant.
Standard ceramic in wet areas
Standard ceramic is still appropriate for bathroom walls in dry zones and powder rooms. In shower enclosures, water absorption compliance is increasingly scrutinised, and ceramic’s porosity is a specification risk in continuously wet environments. The market is shifting toward porcelain even in lower-budget wet area specifications.
High-polish floor tiles in shower enclosures
Polished floor tiles rarely achieve a P4 slip resistance rating. The P-rating requirement for shower floors under AS 4586 is more consistently challenged by building inspectors than it was five years ago, and insurers are increasingly aware of it. The shift to matte and textured floor finishes in wet areas is partly compliance-driven.
Grout-heavy small-format walls
Smaller format wall tiles with wide grout joints are being replaced. Maintenance perception drives it as much as aesthetics: a large grout network in a wet area requires consistent upkeep that most homeowners don’t sustain. Larger formats and panel systems reduce the grout surface area and the maintenance burden with it.

What the Popularity Data Doesn’t Tell You
Popular materials are popular partly because the supply chain around them is efficient. More experienced installers, better product availability, faster lead times, more competitive pricing. Those are legitimate practical reasons to choose a well-established material — not just aesthetic ones. Knowing why something is popular helps you evaluate whether those reasons apply to your project.
But the most-specified material in the market isn’t automatically the right material for a given substrate, compliance context, or maintenance expectation. Large-format porcelain is the dominant aspirational specification right now. It also requires substrate preparation that many low quotes quietly omit. High-polish tiles trend consistently on renovation platforms. They also fail AS 4586 P-rating requirements for shower floors more often than their showroom presence would suggest.
Important: A quote that prices a popular tile without itemising substrate levelling, flexible adhesive, and back-buttering isn’t a saving. The work either gets done or it becomes a repair. If those items aren’t in the quote, ask specifically whether they’re included — not assumed. See common waterproofing shortcuts ›

Common Questions
Porcelain is the most durable practical choice for most residential bathrooms. Dense, hard-wearing, and low-maintenance — it handles the wet area requirements without the trade-offs of more porous materials.
Natural stone is durable when maintained correctly, but the maintenance commitment is higher. Vinyl and painted surfaces deteriorate faster in continuously wet environments regardless of the brand or product specification.
Depends on the application. For shower walls in a rental or investment property, panels often make more practical sense — faster to install, no grout to maintain, and compliant in a wet area when installed over a correctly prepared substrate with an appropriate waterproofing membrane beneath.
For a homeowner who wants a specific tile look, or a bathroom where design flexibility matters, full wet area tiling gives more options. Neither is categorically better. They solve different problems, and the right choice depends on the property, the budget, and who is going to be maintaining it.
Indirectly. Popular materials tend to be popular partly because buyers recognise and respond to them — polished or honed porcelain in a neutral tone reads as quality to most buyers. Niche or heavily dated materials can narrow appeal.
But resale impact is more strongly driven by the quality of the finish and the condition of the bathroom than by the material category. A well-executed renovation in standard porcelain will typically outperform a poorly installed stone bathroom at resale. The material gets you noticed. The installation quality — and the absence of visible defects — is what holds the value.
Large-format tiles — counterintuitive, but fewer grout lines create visual continuity that makes a small space read larger. Light tones and matte or honed finishes. Waterproof panels in a single colour or stone-look finish eliminate grout lines entirely and can work well in confined spaces.
What doesn’t help: busy mosaic patterns across all surfaces, high-contrast grout in a small footprint, or dark wall tiles without adequate lighting to compensate.
Both, in a well-run renovation. The homeowner drives the selection — you’re the one living with or managing the property. A competent renovator confirms that the tile you’ve chosen meets the compliance requirements for its intended location: P-rating for floor tiles, water absorption classification for wet area walls, substrate suitability for the format.
If that conversation isn’t happening in the quote process, initiate it yourself. The right question isn’t just ‘can you install this tile?’ — it’s ‘does this tile meet the AS 4586 classification required for a shower floor, and is substrate preparation for this format included in your quote?’ If you need help identifying a renovator who’ll answer those questions properly, that’s what we do.
