What Does a Bathroom Renovation Involve?

The renovation process step by step

A bathroom renovation runs in a strict sequence of trades. Getting this order wrong causes delays and rework. Here's how it typically runs on the Central Coast:

  • Strip-out & demolition — remove old tiles, fixtures, vanity, and shower screen. Dispose of waste
  • Plumbing rough-in — relocate or replace water supply lines, drainage, and waste pipes to suit the new layout
  • Waterproofing — membrane applied to floors and wet-area walls per Australian Standard AS3740, then inspected before tiling
  • Tiling — floor and wall tiles laid, grouted, and sealed
  • Plumbing fit-off — vanity, toilet, shower, tapware, and accessories installed
  • Electrical & finishing — lighting, exhaust fan, heated towel rail, mirrors, and paint

Trades involved

A full bathroom renovation on the Central Coast involves multiple licensed trades working in sequence:

  • Licensed plumber — handles all rough-in and fit-off plumbing, and often coordinates the other trades
  • Waterproofer — applies certified membrane to shower recesses, floors, and wet walls
  • Electrician — wiring for lighting, exhaust fans, power points, and heated towel rails
  • Tiler — floor and wall tiling, including feature walls and niches
  • Carpenter & painter — cabinetry, door frames, and finishing touches

How long it takes and what it costs

Cosmetic refresh (new tiles, vanity & tapware) $10,000–$15,000 2–3 weeks
Mid-range full renovation $20,000–$30,000 4–6 weeks
High-end / custom bathroom $35,000–$50,000+ 6–8 weeks
Ensuite addition (new room) $25,000–$45,000 6–10 weeks

Labour accounts for roughly 40–50% of total cost. Prices vary by scope, finishes, and whether plumbing needs to be relocated. Always include a 10–20% contingency.

Advice for property managers

Bathroom renovations in rental properties on the Central Coast are one of the highest-ROI upgrades you can make. A dated bathroom is the number one turn-off for tenants and often the reason properties sit vacant longer than they should. Even a mid-range refresh — new vanity, re-tiling, and modern tapware — can increase weekly rent and reduce vacancy periods.

Signs It's Time for a Bathroom Renovation

Cracked or missing grout and tiles

Cracked tiles and deteriorating grout aren't just ugly — they let water seep behind walls and under floors. On the Central Coast's older homes, this is a common path to hidden water damage and mould growth.

Persistent leaks or dripping taps

A tap that drips after turning off or a shower that weeps constantly is wasting water and money. If you're patching leaks regularly, it's a sign the plumbing and fixtures need a proper upgrade, not another repair.

Mould or mildew that keeps coming back

If mould returns no matter how often you clean, the problem is likely poor ventilation or failed waterproofing. Coastal humidity on the Central Coast makes this worse. A renovation with proper waterproofing and an effective exhaust fan solves it permanently.

Dated layout and fixtures from the 80s or 90s

Pastel-coloured suites, wall-mounted basins with exposed plumbing, and cramped shower-over-bath combos. Many Central Coast bathrooms haven't been touched since the house was built. A modern renovation transforms both the function and the feel.

Water stains on ceilings or walls below

Water stains on the ceiling below a bathroom or bubbling paint on adjacent walls are signs that waterproofing has failed. This is especially common in older Central Coast homes where original membranes have deteriorated over decades.

Bathroom Renovation Central Coast FAQs

How much does a bathroom renovation cost on the Central Coast?

With Alljack you get 3 competitive quotes so you can compare before committing.

How long does a bathroom renovation take?

Most bathroom renovations on the Central Coast take 2 to 6 weeks depending on scope. A cosmetic update — replacing tiles, vanity, and fixtures without moving plumbing — typically takes 2–3 weeks. A full renovation with new waterproofing, plumbing rough-in, tiling, and fit-off runs 4–6 weeks. If you're relocating the toilet, shower, or adding a second bathroom, allow 6–8 weeks. Material lead times and council approvals can add to the timeline.

Do I need council approval for a bathroom renovation on the Central Coast?

In most cases, a like-for-like bathroom renovation on the Central Coast does not require council approval — replacing fixtures, re-tiling, and updating tapware are generally exempt. However, if your renovation involves structural changes (removing or adding walls), altering plumbing or drainage layout, or changing the building's footprint, you may need a Complying Development Certificate or Development Application through Central Coast Council. Your renovator or plumber can advise on what applies to your job.

What trades are involved in a bathroom renovation?

A full bathroom renovation involves multiple trades working in sequence: a demolition team strips out the old bathroom, then a plumber completes the rough-in (relocating pipes and drainage as needed). A waterproofer applies membrane to floors and walls per Australian Standard AS3740. An electrician handles lighting, exhaust fans, and power points. A tiler lays floor and wall tiles, a carpenter fits cabinetry and door frames, and the plumber returns for final fit-off — installing the vanity, toilet, shower, and tapware. A painter finishes the job.

Can I use my bathroom during the renovation?

No — once demolition begins, the bathroom is out of action for the duration of the renovation. If you only have one bathroom, most Central Coast renovators recommend setting up a temporary arrangement — using a second bathroom, a relative's place, or a portable facility. Plan ahead and factor this into your timeline. Most renovators will give you a clear schedule so you know exactly how long you'll be without access.
