Most people renovate a kitchen because the layout finally drove them mad, then put up with the bathroom for another few years. But if both rooms are tired at the same time, doing them together is usually the smarter play. You have the trades on site anyway, the house is already a bit of a building zone, and a lot of the cost hides in the setup, not the tiles.
Here in Wollongong and across the Illawarra we get asked about this a lot, so here is the honest version of why bundling a kitchen and bathroom renovation tends to work out better, and what to watch for.
Why doing both at once saves money
A renovation carries a pile of fixed costs that do not really change whether you do one room or two. Site setup, waste removal, protecting floors and hallways, the plumber's call-out, the electrician's call-out, the tiler mobilising. Split those across two separate jobs a year apart and you pay for them twice.
Do both at once and you spread that overhead across a bigger project. A few specific savings:
- One demolition and one skip run instead of two.
- Trades stay put. A plumber who is already on site to move your kitchen sink can rough in the bathroom the same week, rather than coming back for a fresh call-out.
- Buying in bulk. Tiles, tapware and cabinetry ordered together can mean better pricing and fewer delivery runs.
- Less repeated waterproofing and prep where the wet areas sit near each other.
None of this makes a renovation cheap, and it would be dishonest to pretend otherwise. But the per-room cost usually comes down when you combine them. Treat any figure you read online as a starting point, not a quote, because your block, your existing plumbing and the finishes you pick move the number a lot.
The disruption is shorter, not doubled
The fear is that two rooms means twice the mess for twice as long. In practice it is closer to one longer stretch than two separate ordeals.
When the same team runs both rooms, the trades overlap. While the tiler is in the bathroom, the cabinetmaker can be measuring the kitchen. While the kitchen benchtop is being templated and fabricated (which takes time and happens off site), the bathroom keeps moving. That overlap is where you claw back weeks.
It is worth planning for the awkward stretch though. There will be a period with no working kitchen and possibly no main bathroom, so a temporary setup, a kettle, a microwave and a second toilet or a friendly neighbour, makes life a lot easier.
Sequencing the trades
Both rooms follow a similar order, and the value of one team is that they choreograph it so nobody is standing around and nothing gets done twice.
A rough sequence looks like this:
- Demolition and strip-out of both rooms.
- Rough-in. Plumbing and electrical get moved to suit the new layouts before anything gets closed up. This is the stage to lock in, because changing your mind later means opening walls again.
- Waterproofing the wet areas, which in NSW needs to be done properly and to standard.
- Tiling floors and walls.
- Cabinetry and benchtops, then the kitchen splashback.
- Fit-off. Taps, sinks, the toilet, appliances, lights and the final connections.
Get that order wrong and you get expensive backtracking, a benchtop templated before the cabinets are set, or tiling that has to be cut out because a pipe moved. A builder coordinating both rooms keeps that sequence tight.
Why one team doing both matters
The biggest headache with running two separate renovations is that you become the project manager. You are the one chasing the plumber, checking the tiler turned up, and refereeing when the electrician says the cabinetmaker was in the wrong spot.
With one team handling both rooms, that coordination is our job, not yours. At Ovas Build you get one point of contact, a fixed-price proposal covering both rooms, and a single crew that already knows how your kitchen and bathroom connect behind the walls. We handle design, council approval where it is needed, and the build itself. Most cosmetic kitchen and bathroom work sits within exempt or complying development, but always confirm your own situation with council or a private certifier before you commit, especially if you are moving walls or plumbing.
Is bundling right for your place
Combining works best when both rooms genuinely need doing and your budget can carry the two at once. If the bathroom has a couple of good years left, there is no shame in staging it.
But if you are already living around a dated kitchen and a bathroom you would rather not photograph, one coordinated renovation across the Illawarra or the Southern Highlands usually means less money, less mess and a lot less of your weekend spent chasing tradespeople.
