Bathroom Renovation Questions, Answered — North Shore bathroom renovation

Cost and value

Is it cheaper to renovate the bathroom and laundry together? Almost always. The trades are on site, the skip is ordered, the waterproofing is being done and the tiles arrive in one delivery. The marginal cost of the second room is well below doing it standalone later. Same logic applies to an ensuite done alongside the main bathroom.

Will it add value before I sell? On the North Shore, a dated bathroom is more often a deduction than a new one is an addition — buyers price in the cost and disruption of doing it themselves, and they price it generously. A competent, well-finished renovation is usually a sound pre-sale move. Over-specifying beyond what the street supports is usually not.

Why are quotes so different from each other? Because they contain different things. Check whether each names the fittings by model, states the tile allowance, includes the skip, shows waterproofing cure time in the program, and sets out how variations are priced. The full breakdown is on the cost page.

Design and layout

Should I remove the bath? If the household has another bath or has not run this one in two years, converting to a walk-in shower is usually the highest-return change in a small bathroom. The counter-argument is resale — if it is the only bath in the house, think it through.

Can I move the toilet? Technically almost always, financially it depends on the floor. On a suspended timber floor — common in the interwar housing through Roseville and Willoughby — it is tractable. On a concrete slab, typical of the walk-ups through Chatswood and Crows Nest, it means cutting concrete.

Do large tiles suit a small bathroom? Generally yes — fewer grout lines read as less clutter. The limit is set-out: in a very small room a large format can leave slivers at the perimeter. Ask the tiler where the cuts will land before work starts, not after. More on the tiling page.

During the job

Why does nothing happen for several days in the middle? The screed has to dry and the waterproofing membrane has to cure before tiling starts. That is chemistry, not slack. How a renovation runs sets out where the waiting falls.

What is a variation? Work outside the original scope, usually because something was found once the room was opened up. It should be documented in writing, priced, and approved by you before it proceeds. Verbal agreements in a hallway are how disputes start.

Who cleans up? Rubbish removal and a builder's clean should be in the quote as a line item. If they are not in writing, assume they are not included.

FAQs

Frequently asked questions

How much does a bathroom renovation cost on the North Shore?

As a 2026 planning guide: a powder room $8,000–$16,000, an ensuite $15,000–$28,000, a small bathroom like-for-like $18,000–$28,000, a standard main bathroom $25,000–$40,000, and a large bathroom or any layout change from $40,000 upwards. Those are budgeting ranges — the written quote after a site measure is the number that binds.

How long will it take?

Around 15 to 20 working days for a standard renovation that keeps its layout, which is three to four calendar weeks. Add roughly a week for a layout change, and add the strata approval timeline at the front if it is a unit.

Can I stay in the house while it is done?

Yes if there is a second toilet and somewhere to shower. If it is the only bathroom in the house, make alternative arrangements for the whole period rather than most of it — this is consistently the part people underestimate.

Do I need council approval for a bathroom renovation?

For work that stays inside the existing room, generally not. The exceptions are heritage-listed properties and homes inside a heritage conservation area, which are common across Ku-ring-gai and present through Willoughby and Mosman. There, internal wet-area work can carry conditions. The contractor can tell you what is likely; the council decides.

What about strata approval for a unit?

In a NSW strata scheme, work affecting waterproofing or common property generally needs owners corporation approval before it starts, and most schemes also set permitted work hours and rules for lift access. Start that process early — it is routinely the longest lead item in a unit renovation.

Is the contractor licensed and insured?

The contractor holds the licence and the insurance, not this website. We ask every contractor we work with to hold what the job requires, and we ask that plumbing and electrical work goes to separately licensed trades. We cannot verify it for you on an ongoing basis, so ask to see the certificates before work starts and check the licence number on the NSW Fair Trading register.

What if you find asbestos?

Work stops in that area until it is properly assessed. Asbestos-containing wall sheeting behind tiles is not unusual in bathrooms built before about 1990. Removal is carried out by a separately licensed asbestos removalist — it is not something a general renovation crew handles as part of the job, and any contractor who suggests otherwise should be declined.

How much deposit should I pay?

Less than you might expect. Deposit limits for residential building work in NSW are capped under home building legislation — check the current figure on the NSW Fair Trading site before paying anything. Beyond the deposit, progress payments tied to completed stages are the normal structure.
