Who this guide is for
- Homeowners planning a bathroom renovation
- People wanting to understand the order of work
- Anyone coordinating multiple trades
- Readers avoiding costly out-of-order mistakes
Strip-out and assessment
Work usually starts by removing old fixtures and finishes and assessing what lies beneath. Surprises behind tiles or under floors often surface here.
Conditions found at this stage shape the rest of the plan.
What surfaces during strip-out often reshapes the plan, so building in a moment to confirm the approach after demolition, before committing to finishes, keeps the rest of the sequence on solid ground.
- Remove old fixtures and finishes
- Assess what is behind surfaces
- Note any moisture or damage
- Confirm the plan before rebuilding
Services and rough-in
Plumbing and electrical provisions are planned and roughed in before walls and floors close up. Getting fixture positions right now avoids reopening finished surfaces.
Services work belongs with qualified trades.
Plumbing and electrical positions set before walls and floors close up are what keep fixtures where you want them, so confirming the layout at rough-in stage protects everything that follows.
Waterproofing and substrate
Wet areas need appropriate waterproofing before tiling. This stage is critical and is not something to rush or cover prematurely.
Waterproofing should be carried out by qualified professionals.
Tiling, fixtures and finishing
Tiling, then fixtures, then decoration and accessories follow once the substrate and waterproofing are sound.
Leaving accessories until last keeps the finish clean.

What comes first in a bathroom renovation?
Strip-out and assessment, then services and rough-in. Establishing what is behind surfaces and getting plumbing and electrical right early avoids reopening finished work later.
When does waterproofing happen?
Before tiling, after services and substrate are ready. Waterproofing wet areas is a critical stage that should not be rushed or covered prematurely, and it belongs with professionals.
Why does order matter in a bathroom?
A bathroom concentrates services, waterproofing and finishes in a small space, so working out of order often means removing completed work. A sound sequence protects time and quality.
When do accessories go in?
Last. Tiling, then fixtures, then decoration and accessories follow once the substrate and waterproofing are sound, which keeps the final finish clean.
