Understanding the Typical Bathroom Renovation Timeline
For a full bathroom renovation in Sydney, the average timeline is 3 to 6 weeks. However, this can vary depending on the project size, material availability, and the scope of work involved.
Factors that impact your bathroom renovation duration:
- Bathroom size & layout – Small bathrooms can move faster, but complex layouts take time
- Scope of renovation – A cosmetic refresh is quicker than a full strip-out and rebuild
- Material selection – Lead times for tiles, tapware, or custom vanities can affect scheduling
- Trade availability in Sydney – Skilled trades are in high demand across the Lower North Shore and beyond
- Approvals & compliance – Strata approvals can delay start dates
If you're planning a bathroom renovation in areas like Naremburn, Lane Cove, or Mosman, expect scheduling to vary depending on local access and contractor demand.
Step-by-step breakdown of a bathroom renovation timeline
Pre-renovation phase (1–4 Weeks)
- Design meetings and layout planning
- Site inspections and condition assessments
- Itemised quotes and contract approvals
- Material selections
- Ordering materials (e.g. tiles, vanities, frameless shower screens)
- Scheduling licensed trades and confirming access
Demolition & structural work (Approx. 1 Week)
- Safe removal of floor tiles, wall linings, fixtures, and cabinetry
- Identifying and fixing underlying issues such as water damage or mould
- Disposal and clean-up of all waste material
Plumbing, electrical & waterproofing (1–2 Weeks)
- Plumbing rough-in: Drainage and pipe positioning
- Electrical rough-in: Lighting, GPOs, exhaust fans, heated towel rails
- Certified waterproofing application and drying time (typically 24–48 hours between coats)
- Drying times can vary based on Sydney’s humidity and temperature conditions
Tiling & flooring (1–2 Weeks)
- Laying floor tiles and bathroom wall tiles with required curing time
- Intricate tile patterns or full-height walls can extend this stage
- Grouting, sealing, and waterproofing final checks
Installation of fixtures & fittings (Approx. 1 Week)
- Wall-hung vanity, toilet, mirrors, tapware, shower screens, accessories
- Final electrical and plumbing connections
- Styling, clean-up and final quality inspection
