Dunedin Bathroom Renovation Market
Dunedin's Victorian and Edwardian homes typically have original bathrooms with outdated plumbing and fitments. Bathroom renovations in older Dunedin homes often uncover moisture damage in walls and floors, adding to project costs.
Tradespeople You'll Need
A bathroom renovation involves multiple trades:
- Builder: Project management, demolition, waterproofing, framing changes, and coordination
- Plumber: Toilet, basin, shower/bath connections, relocation if layout changes
- Electrician: Heated towel rail, ventilation fan, lighting, shaver socket
- Tiler: Floor and wall tiles — the biggest visual impact
- Plasterer: Making good walls and ceiling after demolition
A good builder or bathroom company coordinates all trades. Self-managing trades saves the margin (typically 15–25%) but requires significantly more time.
Waterproofing — The Most Important Step
NZ Building Code requires waterproofing in wet areas. This is non-negotiable:
- All shower areas must be fully waterproofed to the correct height (minimum 1,800mm for showers)
- Floor-to-wall junctions are the most common failure point
- Must use a consented waterproofing system with a compliance certificate
- Your builder must be Licensed Building Practitioner (LBP) for restricted work
Warning: Non-compliant waterproofing means invisible rot behind tiles — often not discovered until major damage occurs. Never skip or cheap out on waterproofing.
Do I Need Building Consent?
Usually no for a like-for-like renovation in the same location. Yes if you are: - Moving plumbing to a new location (structural/drainage work) - Removing walls or changing the room's footprint - Adding a new bathroom where one didn't exist
Your builder will advise — most standard bathroom renovations don't require consent.
