One suburb, two renovation markets
Artarmon is divided by the North Shore rail line, and the split runs through the housing as cleanly as it runs through the map.
West of the line is residential Artarmon — interwar and post-war houses on regular blocks, leafy streets, and the kind of original bathroom that was generous in 1938 and is cramped now. Small, centrally planned, and very often with the toilet in a separate room next door.
East of the line runs into the Artarmon industrial area and, further south, toward St Leonards. Here the stock is apartments, both older walk-ups and newer buildings, with compact bathrooms on concrete slabs.
Quoting them the same way would be a mistake, because the single most important variable — whether the drainage can move — differs completely between the two.
The house job
Suspended timber floors are the good news. They mean a waste can be relocated without cutting concrete, which puts a genuine layout change within reach financially.
The change that transforms these houses is combining the bathroom and the separate toilet into one properly proportioned room. Two cramped spaces become one usable one, with room for a real shower, a decent vanity and somewhere to stand. It is the same move that works through Willoughby and Roseville, and for the same structural reason.
Check first whether the dividing wall is carrying load. Often it is not. Where it is, the answer is a beam rather than an abandoned plan — but it belongs in the quote rather than in a discovery on demolition day.
The apartment job
Slab floor, common stack, owners corporation. Same fundamentals as the unit stock through Chatswood and Crows Nest.
Work with the existing waste positions unless there is a compelling reason not to, get the strata application moving early because approval is routinely the longest lead item, and put the budget into the things that actually change the room: removing an unused bath for a walk-in shower, a slimline wall-hung vanity, full-height tiling, and proper light at the mirror.
What to expect on strip-out
An original bathroom from the 1930s or 1940s that has been partially updated once — usually in the 1970s or 1980s — commonly reveals deteriorated wall framing, old cast-iron waste at the end of its life, and sometimes asbestos-containing sheeting from that later refit. The asbestos guide explains how that is handled and who is licensed to do it.
The industrial-area factor
One local quirk worth knowing. The Artarmon industrial area sits immediately east of the line, and it is where a lot of the North Shore's trade suppliers, tile warehouses and joinery workshops actually are.
That has a small but real practical benefit on an Artarmon job: material lead times tend to be shorter, a forgotten item can be collected the same day rather than the next, and a tiler who runs short of adhesive is ten minutes away rather than an hour. It does not change the quote, but it does tend to make the program hold better.
It also means the local trade knowledge in this pocket is genuinely deep. Most of the people who work on North Shore bathrooms pass through Artarmon to pick something up.
What it costs
Artarmon houses with a layout change generally sit in the $25,000–$40,000 range. Apartment bathrooms kept like-for-like mostly land at $18,000–$28,000. The 2026 cost bands set it out in full, and how a renovation runs covers the timeline.

Frequently asked questions
What sort of bathrooms are typical in Artarmon?
Two kinds. West of the line, interwar and post-war houses on conventional blocks with small original bathrooms and often a separate toilet. Around the station and toward St Leonards, apartments on concrete slabs with compact bathrooms connected to a common stack.
Can I change the layout in an Artarmon house?
Usually yes. The interwar housing here sits on suspended timber floors, which makes moving a waste far more tractable than in a slab building. Combining the bathroom with the separate toilet next door is the highest-value change available in most of these houses.
Which council covers Artarmon?
Willoughby City Council, the same authority as Chatswood, Willoughby and Naremburn. For a bathroom renovation staying inside the existing room, council approval is generally not the issue — the exception is a heritage-listed property, which is worth confirming before design decisions are locked in.
Is access difficult in Artarmon?
Less than in most of the lower North Shore. The residential streets are conventional suburban blocks with driveways, so skip placement and material delivery are straightforward. Apartments near the station bring the usual lift and loading-dock constraints instead.
