Muir Plumbing, Gas & Drainage handles all the plumbing work for bathroom renovations — hot and cold supply, waste connections, shower installation, toilet rough-in, and tap fitting. We work with homeowners directly or alongside builders and tilers. Partial renovations (shower + toilet swap) typically cost NZD $1,500–$4,000 for plumbing work.

How long does a full bathroom renovation take?
- The plumbing component of a full reno typically takes 3–7 working days
- We work in stages: rough-in (pipes in walls) then fitoff once tiling is complete
- Total project time depends on your builder and tiler — we coordinate with them
- We give a schedule at the start so you know when to expect each stage

Do you handle shower replacements and toilet installs?
- Yes — shower base and screen installation, waste connection, hot and cold supply
- Toilet suite replacement including waste rough-in, cistern, and seat
- We supply or work with fixtures you've already purchased
- All work meets NZ Building Code G12 (water supply) and G13 (foul water)

What's included in a partial vs full bathroom fitout?
- Partial: swap out fixtures (shower, toilet, vanity) without changing tile layout or wall structure
- Full fitout: demolish existing, relocate waste and supply if needed, rough-in to new plan
- Full fitout requires building consent in some cases — we can advise
- We quote both options clearly so you can make an informed call

Do bathroom renovations need building consent in Auckland?
- Like-for-like fixture swaps (same position, same waste layout) usually don't need consent
- Relocating a shower, toilet, or vanity often triggers consent because you're changing the drainage layout
- Waterproofing membrane work in wet areas must meet NZ Building Code — we install to code regardless
- We advise on consent requirements before quoting so you're not surprised mid-project
