Some bathroom tips

Budget

Bathroom renovation costs vary depending on size, waterproofing, access, plumbing changes, materials and complexity. As a 2026 Sydney planning guide, allow roughly $28,000 to $65,000+ for a full bathroom renovation from 4m² to 9m². Simple cosmetic updates may cost less, while structural changes, custom joinery, premium tiles and concealed plumbing can push the budget higher.

Levels of finish (standard 4m² bathroom)

1. Budget finish — $28,000–$38,000. Simple layout, practical tiles, flat-pack or semi-custom vanity, standard tapware and minimal service relocation.

2. Mid-range finish — $38,000–$55,000. Better tiles, semi-frameless or frameless glass, floating vanity, quality tapware, stronger lighting and ventilation package.

3. High-end finish — $55,000–$75,000+. Custom joinery, large-format or natural stone tiles, concealed plumbing, premium fittings and underfloor heating.

Cost note: updated as an indicative 2026 Sydney planning range. Master Builders Australia reported new-home cost inflation of 2.3% year-on-year in January 2026, reinforcing the need to confirm scope before committing to finishes.

Tiles

• Ceramic — budget-friendly, ideal for walls, ~$30–$50/m². Smaller tiles are cheaper to install; larger formats cost more due to handling and cutting.
• Porcelain — denser and more water-resistant, great for floors and high-use areas, ~$50–$90/m² (install $45–$70/m²).
• Natural stone (marble, granite, travertine) — luxurious but requires sealing and upkeep, from ~$120/m² plus install ($70–$100/m² for large formats).

In Australia, porcelain is the go-to for floors and wet areas; ceramic is a more affordable wall option. For a high-end look, natural stone or terrazzo-look tiles are popular (TileCloud, Beaumont Tiles, KLAY). Large-format tiles open up small spaces; mosaics and Kit Kat tiles add texture for shower floors or feature walls. Go matte on floors (less slippery, meet R10+ slip standards) and glossy on walls for light reflection. Matching grout gives a seamless look; contrast grout highlights the layout.

Bathroom product selection

• Basins & bathtubs — ceramic/vitreous china basins are affordable and easy to clean; stone or concrete feel premium. Bathtubs range from acrylic (light, cost-effective) to steel enamel (durable) and stone/composite (luxury with great heat retention).
• Toilets — entry-level close-coupled from ~$300–$500; in-wall concealed cisterns for a cleaner look from ~$800–$1,500+; smart toilets with bidets and seat warmers from ~$2,000–$3,000.
• Shower screens — frameless glass is sleek and easy to clean; semi-frameless is stylish and more accessible; framed is budget-friendly but heavier. Popular finishes: chrome, matte black, brushed nickel, brushed gold.

Light it right

Layered lighting transforms both feel and function:

• Task lighting near mirrors and vanities — bright but not harsh (LED strips or wall sconces), avoiding shadows on the face.
• Ambient lighting from ceiling or recessed downlights for even, soft illumination — dimmable for flexibility.
• Accent lighting (under-cabinet LED, feature-wall downlights) to add depth and a spa-like feel.
• Natural light via windows or skylights — opens the space and supports mood and circadian rhythm.

Think ventilation

Ventilation is crucial in Sydney’s humid climate — poor airflow breeds mould and mildew. Use a quality exhaust fan sized to the room (roughly 1 CFM per square foot), ideally with a timer or humidity sensor. If you have a window, open it during and after showers. Aim ventilation at high-moisture zones like the shower enclosure, especially in small windowless bathrooms.

Other cost factors

• Size of the space — larger rooms need more materials and labour.
• Scope of work — cosmetic upgrades are cheaper than full remodels.
• Material choices — premium tiles, stone and custom cabinetry cost more.
• Plumbing & electrical changes — moving services adds significant cost in wet areas.
• Structural modifications — removing walls or reinforcing foundations adds complexity.
• Custom vs prefab fixtures — custom joinery costs more than flat-pack.
• Complexity & access — tight spaces, heritage restrictions, or limited access add time.
• Unexpected issues — hidden water damage, mould or old wiring found during demolition.
