What's included

Pro tip: Adding a bathroom to a one-bath home tends to return more than adding a fourth to a three-bath home.

What affects the cost of a bathroom addition

New space vs. conversion
Building out the footprint adds foundation, framing and roofing; converting existing space avoids all three and is far cheaper per bathroom.
Plumbing distance
Tying into nearby supply and drain lines is cheap; running new lines across the house — or adding a stack — adds thousands.
Fixture level
A basic half bath is a fraction of a tiled full bath with a walk-in shower, glass and stone.
Permits & inspection
New plumbing and electrical trigger permits and inspections; venting and code compliance are non-negotiable line items.

How to read these Australia figures. The cost is the US national midrange benchmark adjusted by a Brisbane, AU cost multiplier (1.05×) and shown in AUD. The “% recouped at resale” is a national (US-derived) Cost-vs-Value benchmark applied to the local cost — it is not a locally measured resale figure, and real recovery varies by Australia market conditions. These are planning estimates only; confirm with local contractor quotes and a local agent. Not financial or real-estate advice. Reviewed June 2026. See our full methodology →
