Three wet areas, one budget
The Beaumont Hills housing stock is late 1990s through 2000s, and the typical house has a main bathroom, an ensuite and a powder room. That means the first conversation is not about tiles. It is about which rooms to do.
Three rooms done properly is a $50,000 to $70,000 exercise. Most households do not do that in one go, and they do not need to.
The ensuite argument
If you do one room, the case for the ensuite is stronger than people expect.
It is the room two adults use every morning. It was originally fitted out to the lowest specification in the house — smallest vanity, cheapest tapware, often a shower base rather than a tiled floor. And it is the room where the difference between a good renovation and a bad one is felt every single day rather than noticed by visitors.
The main bathroom gets used by children and guests. The ensuite gets used by the people paying for the renovation.
The case for two together
Doing the main bathroom and the ensuite in the same program is meaningfully cheaper per room. Site protection, the skip, the waterproofer's attendance and set-up, the tile delivery and the trade travel are largely fixed costs, and spreading them across two rooms rather than one takes real money off the second.
The constraint is not financial. It is that a household with two bathrooms out of action has nowhere to shower. In practice most people run them sequentially with a short overlap — the ensuite finishing as the main bathroom starts — which recovers some of the saving without leaving the house without a shower.
A powder room is a different animal: no shower, no bath, minimal waterproofing, and often done in under two weeks for $8,000 to $15,000.
The slab, as everywhere in the Hills
Ground-floor rooms are on slab, so the waste positions are effectively fixed unless you are prepared to cut concrete. Upstairs rooms are on timber and are much more flexible.
In most Beaumont Hills houses, the main bathroom and ensuite are both upstairs. That is where a layout change is actually affordable — and where the waterproofing matters most, because a failure goes into the ceiling below.
What changes without moving anything
The corner shower becomes a walk-in on the same wall. Tiling goes to the ceiling instead of stopping at two metres. The vanity comes off the floor and gains drawers. The spa bath goes, and a freestanding bath or more shower takes its place. That list covers nearly everything people actually want.
What it costs
Main bathroom $24,000–$36,000, ensuite $16,000–$28,000, powder room $8,000–$15,000. Two rooms together run below the sum of the parts. See the 2026 cost bands and how the program runs.

Questions people ask before they commit
Is it cheaper to do two bathrooms at once?
Per room, yes — meaningfully. Site set-up, the skip, waterproofer attendance and tile delivery are largely fixed costs that get spread across both rooms. The constraint is not money, it is how many showers the household can lose at the same time.
Which room should come first?
Usually the ensuite. In most Beaumont Hills households it takes the heaviest use and originally got the lightest fit-out, which makes it the room where a renovation is felt daily rather than admired occasionally.
Do these houses have asbestos?
No. Beaumont Hills was developed well after asbestos cement left residential construction, so there is no sheeting to test and no licensed removal stage.
Can the shower be made bigger without moving plumbing?
Usually yes. Removing a framed corner screen and rebuilding the shower as a walk-in against the same wall keeps the waste where it is while roughly doubling the usable footprint. It is the single highest-return change in most of these rooms.
