Bathroom renovations involve plumbing, waterproofing, tiling and electrical work, often done by different subcontractors. Ask who is responsible for coordinating these trades, how waterproofing is done and what standard it meets, and what the process is if something leaks after handover.

Before you hire a bathroom renovator in Dunedin

Common themes, pricing patterns, and watch-outs drawn from customer reviews and independent research.

What does a bathroom renovation typically cost in New Zealand? expand_more

A standard full bathroom renovation in New Zealand costs between $15,000 and $35,000, with basic refreshes starting from $5,000 to $10,000. Complex projects, such as those involving subfloor replacement, drainage relocation, or high-end fixtures, can exceed $50,000. Waterproofing, tiling, and licensed plumbing work are the biggest cost drivers, so get at least three itemised quotes before committing.

When does a bathroom renovation need a building consent? expand_more

Like-for-like fixture replacements in the same location, such as swapping a toilet or basin, do not require a building consent. Relocating plumbing or drainage, changing the bathroom layout, adding a new bathroom, or removing walls all trigger a consent requirement under the Building Act 2004. Skipping a required consent can result in fines and serious complications when you sell, so check with your local council before work starts if there is any doubt.

How do I know if the waterproofing has been done properly? expand_more

Waterproofing membranes in wet areas must meet NZS 4858:2004 and comply with Building Code Clause E3, covering upstands of at least 100mm at wall junctions and around penetrations. Ask to inspect the membrane before any tiles go down, as this is your only practical opportunity to spot missed areas or inadequate upstands. If waterproofing fails later, your recourse depends on whether a licensed building practitioner carried out or supervised the work, so confirm LBP status upfront through the MBIE register.

What are the warning signs of a bathroom renovator you shouldn't hire? expand_more
  • –Quotes given verbally or without itemised line items make it impossible to hold anyone to an agreed scope or price.
  • –A renovator who cannot confirm which consents are required, or who suggests consents are unnecessary without checking with the council, is a risk.
  • –Subcontracting plumbing, waterproofing, or tiling without telling you upfront means you have no visibility over who is responsible if something fails.
  • –Slow or absent communication once a deposit is paid is a strong signal of how problems will be handled mid-project.
  • –No process for dealing with hidden defects, such as rotten subfloor or deteriorated framing, means unexpected costs will be handled reactively and at your expense.
  • –Leaving a site untidy at the end of each day suggests poor site management, which often reflects on the quality of the finished work.
What should you ask before hiring a bathroom renovator? expand_more
  • –Ask whether they handle all trades in-house or subcontract, and if subcontracting, ask who those subcontractors are and whether they are licensed.
  • –Ask for a fixed-price quote with a clear scope, and confirm exactly what is and is not included.
  • –Ask who is responsible for obtaining any required building or plumbing consents and how that cost is handled.
  • –Ask what their process is if hidden problems are uncovered once work begins, including how variations are priced and approved.
  • –Ask how long the bathroom will be out of action and get that timeline in writing, including any dependencies on subcontractor availability.
  • –Ask to see evidence of current LBP registration and, for plumbing work, confirmation the plumber is registered with the Plumbers, Gasfitters and Drainlayers Board.
