Two suburbs, two kinds of bathroom
Lane Cove divides cleanly. Along the Pacific Highway and Burns Bay Road there is a dense band of 1960s and 1970s walk-up flats and newer apartment buildings, close to Lane Cove village. Out on the peninsulas — Longueville, Northwood, Riverview — the housing is detached, often interwar or post-war, on sloping blocks running down toward the Lane Cove River and the national park.
The apartment bathrooms and the house bathrooms need different thinking, and the quote should show which one it is dealing with.
The walk-up flats
Compact bathrooms on a concrete slab, connected to a common stack, inside a strata scheme. It is the same fundamental job as the unit stock in Chatswood and Crows Nest, and the same principles apply.
Work with the existing waste positions unless there is a compelling reason not to. Get the owners corporation application in early, because approval for work affecting waterproofing or common property is normally required and the timeline is usually the longest lead item in the job. Then put the budget into the things that actually change how the room feels: removing an unused bath for a walk-in shower, a slimline wall-hung vanity, full-height tiling, a large mirror and proper light at it.
The peninsula houses
Longueville, Northwood and Riverview houses are mostly on suspended timber floors, which changes the calculus entirely. Drainage can move. A small original bathroom and a separate toilet can become one room. An ensuite can be carved out of a bedroom, provided there is a drainage route with fall available.
The complication here is the slope. Blocks step down from the street, driveways are steep, and the house is often well below the road. Every skip movement and every material delivery costs more labour than it would on a flat block, and that belongs in the quote up front.
Council
Lane Cove Council covers the area. For a bathroom renovation staying within the existing room, council approval is not usually the issue — the exception is a heritage-listed property, where conditions can apply. Confirm the status before design decisions are locked.
What it costs
Walk-up bathrooms mostly land in the $18,000–$28,000 like-for-like band. Peninsula houses with a layout change generally run $25,000–$40,000 and up. See the 2026 cost bands and how a renovation runs.

Frequently asked questions
What is different about renovating a bathroom in a Lane Cove walk-up?
The three constants are a concrete slab, a compact room, and an owners corporation. The slab makes moving wastes expensive, the room size rewards careful layout over ambitious layout, and the strata approval usually needs to be underway before anything else starts. Most of the value comes from fixtures, tiling and light rather than from moving plumbing.
Are the peninsula houses harder to renovate?
Not harder, but often steeper. Longueville, Northwood and Riverview sit on slopes running down toward the Lane Cove River, and blocks frequently step down from the street. That affects skip placement and how far materials are carried, which shows up as labour in the quote. The upside is that these houses generally have suspended timber floors, so drainage changes are far more tractable.
Can I renovate a bathroom in a house backing onto the national park?
Yes — an internal bathroom renovation is not affected by the bushland interface in the way an extension or external works might be. What can be affected is site access and rubbish removal on properties with restricted frontage. Anything touching the outside of the house, or vegetation, is a separate conversation with Lane Cove Council.
Is it worth adding a second bathroom in a Lane Cove house?
In a three or four bedroom house with one bathroom, it is frequently the highest-value work you can do — both for daily life and at sale. The feasibility question is the drainage route: how far a new waste has to travel to reach an existing stack and whether there is fall available. On the suspended timber floors typical of the peninsula houses, the answer is usually yes.
