How Much Does a Bathroom Renovation Cost in Perth?
Bathroom renovation pricing in Perth varies more than almost any other home job, because "renovation" can mean anything from a cosmetic refresh to a full structural rebuild. We're presenting this as three tiers rather than one average, since a single figure would be misleading either way.
Typical price
$10,000–$60,000+ depending on scope
Basic / cosmetic refresh
$10,000–$21,000
New fixtures, tiling, and paint over the existing layout
Mid-range full renovation
$20,000–$35,000
Full strip-out and rebuild, same layout
Premium renovation
$35,000–$60,000+
Layout changes, high-end fixtures and finishes
Pricing sources disagreed significantly on a single "average" bathroom renovation cost, which is why this guide uses three tiers instead - it's a more honest reflection of how much scope changes the price.

What affects the price
- Scope - a cosmetic refresh (new vanity, tapware, paint) vs. a full strip-out and rebuild.
- Quality of fixtures and fittings, from budget-range to premium brands.
- Waterproofing and any structural work uncovered once the old bathroom is opened up.
- Layout changes - moving plumbing (toilet, shower drain) adds significant cost over a like-for-like layout.
- Extent of tiling - floor-to-ceiling tiling costs more than tiling wet areas only.
Frequently asked questions
Why is there such a big range in bathroom renovation cost?
Because "bathroom renovation" covers everything from swapping out a vanity and tapware to a full strip-out with a new layout. The three tiers above reflect genuinely different scopes of work, not just different tradie pricing for the same job.
What's the biggest cost driver in a bathroom renovation?
Moving plumbing is usually the biggest jump in cost - keeping the toilet, shower, and vanity in their existing positions is significantly cheaper than relocating them, even in an otherwise full renovation.
Does the price include waterproofing?
It should for any full renovation - waterproofing is a compliance requirement, not an optional extra. If a quote doesn't clearly include it, ask before accepting.
