How Long Does a Bathroom Renovation Really Take? A Realistic Timeline

One of the most common questions we get asked isn't about cost — it's about time. How long will your home actually be disrupted? The honest answer depends on the size and scope of the job, but most standard Melbourne bathroom renovations follow a similar rhythm. Here's a realistic, week-by-week breakdown.

Before the Trades Arrive: Design and Planning (1–3 Weeks)

This stage happens before any physical work starts, and rushing it is the single biggest cause of delays later. It includes the on-site measure, finalising your layout and fixture selections, confirming a fixed-price quote, and ordering any long-lead-time items like custom joinery or imported tiles. Popular tiles and fixtures can take 1–4 weeks to arrive, so selections made early keep the build phase moving without gaps.

Week 1: Demolition and Disposal

Old fixtures, tiles and, where required, plasterboard come out, and the space is stripped back to the studs and slab. This is usually the loudest and dustiest part of the project, typically taking 2–4 days depending on how much needs to be removed, and we sheet off adjoining areas to contain dust as much as possible.

Week 1–2: Plumbing and Electrical Rough-In

With the room stripped back, plumbers and electricians reposition or run new pipework and cabling for the new layout — this is the point where moving a toilet, shower or vanity actually happens. Any structural changes, like widening a doorway or removing a wall, also happen in this window.

Week 2: Waterproofing

Waterproofing membrane is applied to the shower base, walls and any other wet areas, then left to cure fully before tiling begins — usually a non-negotiable 24–48 hour cure period per coat, and often 2–3 coats depending on the area. This is the stage where cutting corners causes the most expensive problems years later, so we don't compress this timeframe regardless of the overall schedule.

Week 2–3: Tiling

Floor and wall tiling typically takes 4–7 days for a standard bathroom, longer for large-format tiles, intricate patterns, or full floor-to-ceiling tiling in a larger ensuite. Grout then needs 24–72 hours to cure before the room can be sealed and used.

Week 3: Fixing and Installation

Vanity, toilet, shower screen, tapware, mirrors, and any joinery are installed, followed by final plumbing and electrical connections — power points, lighting, exhaust fan, and testing every fixture for leaks or faults before sign-off.

Week 3–4: Final Details and Handover

Painting, silicone sealing, hardware installation and a final clean happen in this last stretch, followed by a walkthrough inspection where we check every detail against the original quote before handing the finished bathroom back to you.

Typical Total Timeframes by Project Size

• Small bathroom or partial refresh: 2–3 weeks on-site
• Standard bathroom or ensuite renovation: 3–4 weeks on-site
• Luxury renovation with custom joinery and layout changes: 5–7 weeks on-site

These figures are for the on-site build only — add your design and selection period (1–3 weeks) and any permit or approval time on top if your project needs it.

What Actually Causes Delays

The most common causes of a blown timeline are late fixture selections, discovering hidden damage once demolition starts, and using separate uncoordinated tradespeople instead of one team managing the schedule. A single point of project management — where waterproofing, tiling, plumbing and electrical are booked in sequence by one team — is what keeps a renovation moving at the pace it's quoted at, rather than stalling between trades.
