Thinking about a bathroom refresh or a complete redesign? Here’s a practical, WA‑specific price guide that explains what bathroom renovations really cost in 2025, how to plan your budget, and where you can save without compromising quality.
What drives bathroom renovation cost in Australia
Every bathroom is unique, but most budgets are driven by the same factors:
- Size and complexity (ensuite vs family bathroom; small bathroom vs large)
- Layout changes (moving plumbing or walls increases cost)
- Tiling coverage and tile type (full-height tiling, mosaics, rectified porcelain tiles)
- Waterproofing and compliance to AS 3740 (wet areas), electrical to AS/NZS 3000
- Cabinetry and vanity quality (custom cabinetry WA, soft-close drawers, 2Pac finishes)
- Benchtops and basins (porcelain/“sintered stone” vs laminate; undermount basin)
- Fixtures and tapware (mixer sets, rain showers, heated towel rails, matte black or brass)
- Shower screens (semi-frameless, frameless, walk‑in shower)
- Ventilation and lighting (exhaust fans, LED strip lighting, GPOs)
- Project management, trades availability and site access
PC items are allowances for fixtures you’ll select later (e.g., a $600 mixer). PS covers work that’s hard to price upfront (e.g., extra carpentry after demolition). Always confirm what’s included.

Materials & finishes for WA bathrooms
Benchtops and vanity surfaces
With the prohibition on high‑silica engineered stone in Australia, many clients are choosing porcelain or “sintered stone” as a premium, heat‑resistant surface with excellent water performance. Laminate remains a cost‑effective choice with a huge range of stone‑look décors.
Porcelain / Sintered Stone vs Laminate (for bathroom vanities)
| Feature | Porcelain / Sintered Stone | Laminate |
|---|---|---|
| Typical installed cost (WA) | $650–$1,200 per m² | $180–$380 per m² |
| Water & heat resistance | Excellent; suitable for wet areas | Very good for water; avoid high heat exposure |
| Seams & edges | Minimal joins, crisp edges | Laminated edges; mitred options available |
| Maintenance | Low; non‑porous and highly durable | Low; avoid harsh abrasives |
| Look & feel | Premium stone/terrazzo looks, matte or satin | Wide décor range; excellent value |
| Notes | Common replacement for legacy engineered stone benchtops | Best for budget‑friendly bathrooms and rentals |
Note: “Engineered stone benchtop” historically referred to quartz composites. In Australia, high‑silica engineered stone is prohibited. We help you select compliant alternatives like porcelain “slabs” that offer a similar aesthetic and performance.
Tiles and grout
- Floor: Porcelain with P3–P4 slip rating for family bathrooms; epoxy grout for mould resistance.
- Walls: Ceramic or porcelain; consider full-height tiling in showers for easier cleaning.
- Features: Mosaic niches, stone‑look large format, or a handmade‑look splashback tile to tone with a shaker kitchen or Hamptons style elsewhere in your home.
Cabinetry and finishes
- Cabinetry: Moisture‑resistant board, custom cabinetry WA, soft‑close drawers, internal organisation.
- Finishes: High‑quality laminates, thermolaminated Shaker profiles, or 2Pac polyurethane for a premium painted look.
- Hardware: Quality hinges and runners, integrated handles or classic knobs to match a Hamptons scheme.
Wet area waterproofing must be installed by a qualified applicator to AS 3740. In WA, bathrooms need compliant membranes, falls to waste and curing before tiling.
