Bungalows with bathrooms designed for 1935
Willoughby, Naremburn and the streets running toward Castlecrag are dominated by Californian bungalows and Federation-era houses, and the bathrooms in them were planned for a very different household. Small, centrally located, and with the toilet in its own separate room next door — sometimes with its own door to the hallway, sometimes accessed from outside entirely.
That layout is the opportunity. Two small rooms make one good one, and in these houses the floor is suspended timber rather than a concrete slab, which means the drainage can actually move without cutting concrete. The result is not a refreshed bathroom, it is a different bathroom.
The one thing to establish before committing is whether the dividing wall is doing structural work. Often it is not. Sometimes it is, and then the answer is a beam rather than an abandoned plan — but it needs to be known at quoting stage, not discovered on demolition day.
What these houses hide
An original 1930s bathroom that has been in continuous use for ninety years has usually been repaired at least twice, and not always well. The common finds on strip-out are deteriorated wall and floor framing where water has been tracking, rusted-through cast-iron waste, and asbestos-containing sheeting installed during a 1960s or 1970s refit.
None of that is a reason not to renovate. It is a reason to make sure the quote sets out clearly how discoveries are priced and approved, so that a variation is a documented decision rather than an argument. If asbestos is found, work stops in that area and a separately licensed asbestos removalist handles it — not the renovation crew.
Council and heritage
Willoughby City Council covers Willoughby, Naremburn, Artarmon, Castlecrag and Chatswood. Heritage items and conservation considerations exist across the older streets. For a bathroom that stays inside its existing footprint this is rarely an obstacle; for anything touching external fabric it is worth checking first.
What it costs
Most Willoughby jobs are house renovations rather than unit ones, and combining a bathroom and toilet puts them into the layout-change territory: typically $25,000–$40,000, and above that where the room is large or the specification is high. The cost page has the 2026 bands, and how a renovation runs covers the four-week program.

Frequently asked questions
Should I combine the bathroom and separate toilet?
In a Willoughby bungalow it is very often the single best move available. The two rooms together typically make one properly usable bathroom with space for a real shower and a decent vanity, and because the floor is suspended timber the drainage change is far more tractable than it would be on a slab. The wall between them does need checking for structural role before anything is committed.
Is my Willoughby house in a conservation area?
Parts of the Willoughby local government area include heritage items and conservation considerations, particularly among the older bungalow and Federation streets. For internal wet-area work this is usually not an obstacle, but it is worth confirming the status of your property with Willoughby City Council before locking in a design that touches walls or windows.
What is behind the tiles in a 1930s bathroom?
Often more than anyone hopes. Original bathrooms of that era commonly reveal deteriorated framing where water has been tracking for decades, old cast-iron waste pipe that has rusted through, and sometimes asbestos-containing sheeting from a later refit. That is why the variation clause in your quote matters — and why asbestos, if found, goes to a separately licensed removalist before work continues.
How long does a Willoughby bungalow bathroom take?
Allow four to five working weeks where the bathroom and separate toilet are being combined, against three to four for a renovation that keeps its existing footprint. The extra time goes into the wall removal, any structural work it requires, and the additional plumbing to reposition the wastes. The waterproofing cure time stays the same either way.
