Overview
A Bathroom Renovation Built to Last
Bathrooms reward getting the details right the first time — proper waterproofing, done to AS 3740, protects your home for decades. We treat it as a core standard on every job, not a line item you're upsold on.
As a licensed builder we manage plumbing, electrical, tiling and waterproofing under one roof, with every cost disclosed and one flat, locked management fee — no separate margin from a bathroom-only subcontractor stacked on top.
What's typically included
Waterproofing to AS 3740 (WA's legal standard for wet areas)
Fixtures, fittings and vanity installation
Plumbing and electrical relocation or upgrades
Asbestos testing on pre-1990 homes before demolition begins
Frameless screens, in-floor heating and other upgrades on request
Full compliance with WA building and plumbing regulations

FAQ
Common Questions
A basic renovation with a budget fit-out typically runs $10,000–$18,000. A mid-range renovation with better tiles, a new vanity and updated fixtures lands around $18,000–$30,000. A high-end renovation with premium fixtures, in-floor heating and a frameless shower screen is $30,000–$55,000+. Use the estimator below for an indicative figure, or get a free, site-specific quote.
Yes — all wet-area work is waterproofed to AS 3740, WA's legal standard for domestic wet areas, as a matter of course, not an upsell. As part of a full renovation, waterproofing typically runs $800–$1,800 for a standard bathroom (more for larger or complex layouts), and it's the one place we won't cut corners — waterproofing failures often stay hidden until there's structural damage behind the wall, which costs far more to fix than to do properly the first time.
Yes — keeping existing plumbing positions rather than relocating them can save roughly $1,500–$4,000 depending on the layout. We'll always tell you honestly whether a reposition is worth the cost or whether the existing layout already works.
Yes, we regularly run these as a combined project — it's often more cost-effective to renovate both at once given shared trade mobilisation (plumber, tiler, electrician) rather than staggering them separately.
Older homes in Perth's western suburbs — particularly pre-1990 builds — sometimes have asbestos sheeting behind tiles or under old flooring. We test for this during the site assessment and, if present, arrange safe, licensed removal as a budgeted part of the project rather than a surprise mid-renovation.
You see the real, invoiced cost of materials and trades, plus one flat, locked management fee agreed before work starts — the same rate regardless of project size, with no separate margin hidden inside supplier quotes.
A standard bathroom renovation typically takes 3-5 weeks from demolition to handover, depending on tile and fixture lead times. Larger renovations with structural or layout changes can run 6-8 weeks.
Yes — it's free, gives an instant indicative estimate, and you don't need to submit any details unless you want a formal, site-specific quote afterward.
It's a genuine indicative range based on real Perth renovation rates for finish level, not a marketing number. Your exact cost depends on your existing bathroom, waterproofing needs and chosen fixtures, confirmed during a free assessment.
