The tiles are the easy part. What sits behind them decides how the room ages.
Plenty of Dunedin bathrooms are still doing the job they were built to do in 1965. The extractor fan lost its fight with steam years ago, and winter turns the room into a cold store. There are a myriad of bathroom renovations Dunedin families can try, but it can only be successful as long as the parts you never see are drawn properly first.

In short: Eco Workshop designs bathroom renovations for Dunedin and Otago homes, from a single-family bathroom to a new ensuite layout. Every drawing set covers the wet-area details that matter most in an older house: waterproofing, ventilation, plumbing runs, and tiling substrates. Plans are prepared by an LBP Design 2 accredited designer (a Licensed Building Practitioner). Where building consent is required, the studio provides the documentation needed for council assessment, including the Certificate of Design Work where applicable. Your builder prices from accurate drawings instead of guesswork. Working with an experienced bathroom designer Dunedin homeowners trust helps resolve layouts, wet-area details, and construction requirements before your builder prices from accurate drawings instead of guesswork.
A full bathroom renovation covers everything from the layout down to the plumbing and electrical changes hidden behind the walls. The renovation process starts on paper, with a design you approve and a documented set that every trade can work from. A typical drawing set covers:
There is a practical reason design comes before demolition. Once the Dunedin City Council accepts a consent application, a statutory 20 working day clock starts. Well-resolved documentation moves through cleanly; gaps come back as requests for further information and stall the job.
Eco Workshop is a design studio rather than a build firm. Project management of the drawings and consent submission sits with the team while you choose the builder you trust, as part of the wider renovations service.

Often, no. Much of what a bathroom renovation involves is exempt work under Schedule 1 of the Building Act 2004, and consent only enters the picture when the work goes further. Here is where the line usually sits:
| Usually exempt under Schedule 1 | Usually needs building consent |
|---|---|
| Replacing fixtures and linings like-for-like | Adding new plumbing fixtures, such as an ensuite, where there was none |
| Relocating a sink, tap, basin, or toilet (Exemptions 32 and 33) | Altering a load-bearing or bracing wall |
| Upgrading a hot water cylinder | Any work that affects weathertightness |
Where consent does apply, designing a wet area for consent means showing the council how the waterproofing and drainage will comply, and that documentation is part of the drawing set.
Rules change, so every consent claim in your plans is checked against the current building work guidance before drawings are finalised.

Bring a photo of your bathroom and a rough idea of what you want. We can tell you if it needs consent and what it is likely to cost. No obligation. No pressure. Call (03) 455 1505 or contact us online.
Good bathroom design for an old villa or ex-state home starts with what the building is already doing with its floor levels, framing, and moisture. Dunedin’s older houses were built long before tanked showers and ducted extraction, so the design has to add them without fighting the original structure.
That is detail work. Tanking a shower over timber substrates. Ducting an extractor fan outside rather than into the roof cavity. Running new pipework through framing that predates standard sizes. An ensuite design Dunedin homeowners choose for an older home usually asks for more than the like-for-like replacement Schedule 1 allows, and the drawings need to prove it will work. The Bathroom Revamp and Tile and Timber projects show where that thinking ends up.
The bathroom renovation cost Dunedin homeowners can expect depends on how many changes are behind the walls, not on how the finished room looks. Keeping the existing layout keeps plumbing runs short and prices down. Moving fixtures, enlarging the wet area, or adding custom joinery all add to it, and where consent applies, DCC consent fees sit on top of the design and build.
You get a clear fee proposal before committing to anything. We would rather talk numbers early than surprise you later.
A bathroom renovation in an older Dunedin home needs plans that get the wet-area details right the first time: waterproofing, ventilation, plumbing runs, and the consent documentation to prove it. Eco Workshop’s technical detailing makes sure nothing gets missed on paper before it gets missed on site. For bathroom renovations Dunedin NZ homeowners can confidently plan, the process starts with accurate drawings, clear documentation, and a free chat about what your bathroom needs.
