Big houses, small bathrooms
St Ives is dominated by post-war brick-veneer housing on large blocks, built through the 1950s, 1960s and 1970s as the suburb expanded around the shopping village and the Showground. The houses are generous — three or four bedrooms, decent living areas, substantial gardens.
The bathrooms are not. A four-square-metre main bathroom with a separate toilet next door is the standard arrangement, and it has aged worse than any other part of these homes. The whole renovation opportunity in St Ives sits in that mismatch: the floor area exists, it was simply allocated somewhere else.
The two moves that work
Combine the bathroom and the toilet. The dividing wall between them is frequently non-structural in a brick-veneer house, and removing it produces a single room with enough space for a proper shower, a real vanity and somewhere to stand. The construction generally permits the drainage change without the concrete-cutting that would be required in the slab-floor unit stock elsewhere on the North Shore.
Add a second bathroom or an ensuite. These houses commonly have a bedroom that is no longer used as one, or a main bedroom with enough floor area to give up two and a half square metres. The ensuite page covers the design constraints; the practical question is always the drainage route and whether fall is available to reach an existing stack. In a single-storey house on a suspended floor, it usually is.
Both changes do more for how a St Ives house lives than any amount of finish upgrading in the existing footprint.
What to expect on strip-out
A bathroom from this era that has never been fully redone will usually reveal some deterioration in the wall framing behind the shower, and often original waste pipework at the end of its service life. Where a partial update happened in the 1970s or 1980s, asbestos-containing sheeting behind the tiles is a genuine possibility.
Neither is a reason to hesitate. Both are reasons to make sure the quote sets out how variations are priced and approved, and that asbestos, if found, goes to a separately licensed removalist rather than being handled as part of the general work.
Council and the bushland edge
Ku-ring-gai Council covers St Ives. Properties along the interface with the surrounding bushland can carry controls relating to external works and vegetation — those do not bear on an internal bathroom renovation, but they are worth knowing about if the project ever grows.
Heritage conservation areas are less extensive here than in Roseville and Lindfield, reflecting the later development of the suburb.
What it costs
Most St Ives jobs involve a layout change, putting them in the $25,000–$40,000 range, with second-bathroom additions and larger rooms running above it. See the 2026 cost bands and how a renovation runs.

Frequently asked questions
Why are St Ives bathrooms so small relative to the house?
Because they were built to a post-war standard that allocated minimal space to wet areas. A 1950s or 1960s brick-veneer home in St Ives commonly has three or four bedrooms and a bathroom of about four square metres, with the toilet in a separate room. The house has the floor area to fix this — it just was not distributed that way originally.
Can I add a second bathroom or an ensuite?
In these houses it is frequently very workable. The blocks are large, the floor plans are generous, and the construction usually allows a drainage route with fall to an existing stack. Carving an ensuite from a main bedroom, or converting an underused fourth bedroom into a second bathroom, are both common St Ives jobs.
Does being near the bushland affect a bathroom renovation?
Not the bathroom itself. Properties along the interface with Garigal National Park and the Ku-ring-gai bushland can be subject to controls affecting external works and vegetation, but an internal wet-area renovation is not what those controls address. Access and rubbish removal can be more awkward on some of these blocks, which affects labour rather than approvals.
