The Bathroom
Sizing Guide
A bathroom costs more per square metre than any other room in the house, and size is the one thing a buyer never pays extra for.
Five minutes, read against your own plan.
Big Does Not
Mean Better
Buyers do not pay a premium for a big bathroom. They pay for a big bedroom, a big living area, and a bathroom that feels considered.
Waterproofing, tiling, plumbing, glass, stone. Every extra square metre drawn into a bathroom is the most expensive space in the whole build, and it returns almost nothing at resale. The three numbers below get it right without spending a dollar more.
The Full
Bathroom
| What you need | The number |
|---|---|
| Bathroom footprint | 1500 × 3200 |
| Shower | 1500 × 1000 |
| Vanity | 900 |
The number most plans get wrong.
Bathrooms get drawn as a big square because square feels generous on paper. Make it a tight rectangle instead. 1500 by 3200 does everything the square did, and hands one to two square metres back to the room next door. Same expensive wet-area cost, more sellable space.
Cut The Size,
Not The Finish
Right-sizing is not cheaping out. It is moving money off floor area, where a bathroom returns nothing, onto the things a buyer actually feels the moment they walk in: floor to ceiling tiles, a fluted glass shower screen, brushed nickel tapware, the basin, the mirror, the joinery, one wall light orb that lifts the whole room. And the square metres you saved go straight into the bedroom next door.

I build and develop some of the most iconic homes in Melbourne, in the best streets. Then I sell the result. That is a different lens to a designer, and it is why I notice these things: I find out what a decision was worth at the moment somebody either pays for it or does not.
These are numbers from my own homes, not a mood board.
