Ask who is responsible for the design and 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
Drawn from 175 customer reviews collected for this page. The first answer is what it costs.
What does a bathroom renovation typically cost in New Zealand? expand_more
A basic bathroom refresh, covering cosmetic updates and like-for-like fixture replacement, runs from around $5,000 to $10,000. A full renovation with new tiling, waterproofing, and updated fixtures sits between $15,000 and $35,000.
Complex projects involving layout changes, high-end fixtures, or structural work can exceed $50,000. Waterproofing, tiling, and licensed plumbing labour are the biggest cost drivers in most projects.
When does a bathroom renovation need a building consent? expand_more
Like-for-like fixture replacement, such as swapping a toilet or basin in the same position, does not require a building consent. If you are relocating plumbing, changing the bathroom layout, adding a new bathroom, or removing walls, a consent is required from your local council before work begins.
All plumbing and drainage work is restricted work under the Building Act 2004 and must be carried out by someone registered with the Plumbers, Gasfitters and Drainlayers Board, regardless of whether a consent is needed. Skipping a required consent can result in fines and create serious complications when you sell the property.
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 New Zealand Building Code Clause E3, with upstands running at least 100mm up walls above the floor and fully lapped at corners. Ask to inspect the wet area membrane before tiling begins, as once tiles go down there is no way to verify what is underneath without destructive investigation. Work forming part of a larger renovation should be carried out or supervised by a Licensed Building Practitioner, whose licence you can verify through the Ministry of Business, Innovation and Employment register, and you should receive a record of work on completion.
What are the warning signs of a bathroom renovator you shouldn't hire? expand_more
- –A quote given verbally or without itemised line items for labour, materials, waterproofing, and subcontractor costs is a red flag before work even starts.
- –An unrealistically short timeframe stated at the outset, such as ten working days for a full demolition and rebuild, can signal that the scope has been underestimated to win the job.
- –Painting or finishing work left incomplete, with paint on tiles, glazing, and fittings not cleaned up, points to poor site management and a low standard of care.
- –An owner or contractor who responds to complaints with hostility rather than solutions is a serious warning sign that disputes will not be resolved professionally.
- –No clear explanation of who is responsible for obtaining building consents and coordinating licensed tradespeople suggests gaps in project management.
- –Screening enquiries with intake forms that ask for your budget and competitor quotes, then declining jobs without explanation, suggests the business prioritises certain job sizes over straightforward customer service.
What should you ask before hiring a bathroom renovator? expand_more
- –Ask whether the quote is fixed-price or an estimate, and confirm what triggers variation costs, particularly if hidden damage such as rotten framing or subfloor issues is found once walls are opened.
- –Ask who handles plumbing, electrical, and waterproofing work, whether those tradespeople are employees or subcontractors, and confirm they hold current licences verifiable through the Plumbers, Gasfitters and Drainlayers Board or the Electrical Workers Registration Board.
- –Ask who is responsible for determining whether a building consent is required and for lodging that consent with the council before work begins.
- –Ask for a realistic timeline with a clear explanation of when the bathroom will be usable versus when the project will be fully complete, as these are often different dates.
- –Ask how changes or unexpected issues discovered mid-project will be communicated and priced, and request that any agreed variations be confirmed in writing before additional work proceeds.

How are the top bathroom renovators in Dunedin chosen? expand_more
We build this page from Google Maps results for bathroom renovators in Dunedin. Each one is scored on its public rating and review record. Businesses outside the area, or whose reviews describe a different line of work, are left out, and a business whose main Google category is a different trade is held back until a person has checked what it does. A business whose website no longer resolves and that has had no Google review for six months is treated as dormant and left off the page until either changes. Every category and city is rechecked on a rolling cycle, about every two to three months. A location with a subscribing business is rechecked every month, and the whole page updates with it. See how we rank for the full method.
