Bathroom renovations · Sydney
High-end bathroom renovations across Sydney — strip-out to fit-off under one builder. Waterproofed to standard, set out properly, finished in stone and brass. Every photograph on this page is a completed LetsBuild bathroom.
What it actually is
A bathroom renovation is strip-out, carpentry, rough-in, waterproofing, screed, tiling and fit-off — in that order, each trade dependent on the one before it. The finish everyone sees is decided by the set-out nobody does. Get the falls, the junctions and the membrane right, and the stone is the easy part.

Our work · Glenorie
The main bathing space at our Glenorie build runs from the bedroom through a glass-walled ensuite to a private bathing courtyard — freestanding bath inside, carved stone tub under the sky, one palette of stone, timber and brass throughout. These are photographs of finished LetsBuild work, not renders.

What moves the cost
Two bathrooms with the same tiles can land tens of thousands apart. The spread is rarely the finishes — it is how much of the room moves. Five questions set a bathroom budget, long before anyone chooses a tap.
Like-for-like keeps the falls — moving the shower or WC re-cuts the slab
New fixture positions mean new falls, and falls are earned in concrete
The membrane is redone whole and cured to AS 3740:2021 — never patched
Large format and natural stone carry setting-out time, not just unit price
Wall-hung vanities and shaving cabinets are set out before sheeting, not after
No dollar figures here by design — a range that ignores your layout is a guess. A walkthrough prices the actual room.
The range
The same care at every scale. The ensuite gets the headlines; the family bathroom and the powder room get the same stone language, the same brass, the same set-out discipline.

How it runs
Typical program six to twelve weeks depending on scope, one lead builder throughout, inclusions and exclusions on paper before strip-out. The days the room sits "empty" are the membrane curing — that time is the job being done properly.
Questions
The same questions come up on every bathroom. Short answers below — the conditions are specific to your room and your lot, so confirm before you rely on them.
Usually not. Renovating within the existing room — new fixtures in the same positions, retiling, new joinery and finishes — is generally exempt development under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008. Approval enters the picture when walls move, drainage is relocated, the wet area grows, or a new bathroom is added. The conditions are specific, so confirm your scope with your council or a registered certifier.
AS 3740:2021 — the Australian Standard for waterproofing of domestic wet areas. It grades the room by risk, with enclosed and unenclosed showers highest, and sets out what must be waterproofed and how. In NSW the membrane goes in by a licensed waterproofer and a certificate of compliance is issued and kept. That certificate matters for insurance and resale, not just handover day.
Because drainage has to fall, and the falls live in the slab or the floor structure. Relocating a WC or a shower means cutting and re-forming those falls, new penetrations, and sometimes a hydraulic redesign — work across three licences before a single tile goes on. Keeping fixtures where they are is the single biggest cost decision in a bathroom.
Typically six to twelve weeks depending on scope. The sequence is fixed: strip-out, carpentry and rough-in, waterproofing and its cure time, screed, tiling, fit-off. The membrane's cure days cannot be compressed — a bathroom finished fast is usually a bathroom waterproofed badly.
Usually, if the house has a second bathroom that stays in service. The work area is isolated for dust and the water is off only for planned windows. If it is the only bathroom, we stage the program and tell you honestly which days are the hard ones.
No. A bathroom fails at the junctions between trades — exactly where a split contract has no owner. We take the room from strip-out to fit-off under one builder, so the set-out, the membrane and the finish are one person's responsibility and the guarantee means something.
