Our Bathroom Renovation Process, Step by Step

Most of the stress in a renovation comes from not knowing what happens next. Here is the whole run of a Coast bathroom job, start to finish.

Licence and insurance details are provided on your discovery call, or whenever you ask. Request them →

Stage 1 — Chat and site visit

A quick call to understand the room and what is not working. Then a visit to measure, take photos, check the floor construction, look for signs of leaks or mould, and talk about how the household uses the room.

Stage 2 — Layout and ideas

A layout that fixes the problems you raised, with options where they make sense: keep or lose the bath, move the toilet or not, niche positions, vanity width.

Stage 3 — Selections

Tiles, tapware, vanity, toilet, screen, lighting and accessories chosen and confirmed. Coastal-grade finishes are recommended for homes near the water.

Stage 4 — Written price and contract

An itemised price that names the fittings and states the tile allowance. For jobs over $20,000, home building compensation cover is arranged before any deposit is requested, and the deposit is no more than 10 per cent.

Stage 5 — Approvals and ordering

Strata approval for units. Materials ordered so they arrive before they are needed. A start date locked in.

Stage 6 — Asbestos check

For homes built or renovated before about 1990, suspect materials are sampled. If asbestos is present, a licensed asbestos removalist handles it before general demolition.

Stage 7 — Strip-out

Protection laid through the house, the room taken back to frame or slab, and waste removed.

Stage 8 — Repairs and rough-in

Any rotten framing or joists repaired. Plumbing and electrical run to the new positions.

Stage 9 — Sheeting and waterproofing

Wet-area sheeting fixed, then the membrane applied by a licensed waterproofer and left to cure fully.

Stage 10 — Tiling

Screed and falls, floor tiles, wall tiles, niches, grout and sealant.

Stage 11 — Fit-off

Vanity, toilet, tapware, screen, mirror, lights, fan and accessories installed and tested.

Stage 12 — Clean and handover

A walk-through together, care instructions for the fittings, the waterproofing certificate and warranty paperwork.

Living with one bathroom

Plenty of Coast homes, especially cottages and units, have just one. A few options that work: staying with family for the worst week, a gym or pool membership, a hired portable bathroom, or doing a laundry or ensuite first so there is somewhere to shower.

FAQs

Questions people ask before they commit

How long does a bathroom renovation take from first call?

Allow a few weeks for the site visit, design, selections and ordering, plus any strata approval, then roughly three to four weeks on site for a main bathroom. Small bathrooms and laundries can be shorter; large or complex rooms longer.

Why can't the tiler start the day after waterproofing?

The membrane must cure fully before tiles go on, and humid coastal weather can slow drying. Rushing that stage is one of the most common causes of leaks later.

What if something unexpected turns up behind the tiles?

Older Coast homes sometimes reveal rot, old pipework or asbestos once the room is opened. Work pauses, you are shown the issue and the cost to fix it, and nothing proceeds on extras without your written approval.

Do we need to move out?

Usually not if there is a second bathroom or at least a separate toilet. Single-bathroom households often arrange showers with family, at a gym or pool, or hire a portable bathroom for the weeks the room is out.
