A bathroom renovation transforms how the day begins and ends.
Bathrooms in older Auckland homes are usually the tightest, darkest, most poorly ventilated rooms in the house. Most renovation projects come to us with the same complaints — cramped layouts, terrible storage, weatherboard rot behind the shower, and waterproofing that should have been done properly 15 years ago.
Bathroom renovations look simple from the outside but hide more risks than any other room — waterproofing, structural rot, plumbing reconfiguration, ventilation. Unlike standard bathroom renovation builders Auckland-wide, we plan for the unseen work first, so the finished bathroom stays watertight for decades.

Bathroom Additions
Adding a bathroom to an extension, garage conversion, or upper-floor addition. Full plumbing reconfiguration, council consent, and stack design from scratch.

The questions Auckland homeowners actually ask.
How much does a bathroom renovation cost in Auckland?
Bathroom renovations in Auckland typically cost between $25,000 and $65,000+ plus GST, depending on size, fittings, tiling, and the level of plumbing and structural work required. A simple tile-and-fittings refresh starts at around $18,000–$25,000. A full master ensuite with freestanding tub, walk-in shower, marble tiling, and underfloor heating can reach $80,000–$100,000+.
For the full 2026 cost breakdown — including hidden waterproofing costs and real Auckland project examples — see our Auckland Renovation Costs Guide.
How long does a bathroom renovation take in Auckland?
A standard Auckland bathroom renovation takes 3–6 weeks of on-site construction, plus 3–4 weeks of design and tile/fittings procurement before construction begins. Total project duration is usually 2–4 months from initial consultation to handover. Bathrooms with structural reconfiguration or plumbing relocation can take longer.
Do I need building consent for a bathroom renovation in Auckland?
A like-for-like bathroom refresh (replacing fittings, tiles, vanity in the same positions) doesn’t usually need building consent. However, you’ll need consent if you’re relocating plumbing fixtures (toilet, shower, bath), altering load-bearing walls, cutting new windows, or undertaking weathertightness work behind the cladding. Add Value Renovations manages the entire Auckland Council consent process when required.
Why does bathroom waterproofing matter so much?
Bathrooms are the single most common cause of hidden structural damage in older Auckland homes. Poor waterproofing leaks slowly behind tiles into framing, joists, and wall cavities — and you usually don’t notice until rot has set in. Every Add Value Renovations bathroom includes full membrane waterproofing to NZS 3604/AS 3740 with an independent waterproofing certificate before tiling begins.
Can I still use my home during a bathroom renovation?
Yes, in most cases — provided you have at least one other working bathroom in the home. For homes with only one bathroom, we’ll plan the build schedule to minimise the gap, and discuss temporary arrangements (portable toilet, shower at the gym/friends) during the few days of peak disruption.
Should I get a separate plumber, tiler and builder — or use a design-and-build company?
Bathroom renovations involve more trades in a small space than almost any other room — plumber, electrician, tiler, plasterer, painter, joiner, waterproofer. Coordinating these separately is where bathroom projects most often go wrong. Our design-and-build approach means one contract, one project manager, and one accountable point of contact for every trade.
What’s the difference between an ensuite and a master ensuite?
An ensuite is any bathroom directly accessed from a bedroom. A master ensuite is the bathroom attached to the master bedroom — usually larger, with separate vanity, walk-in shower, often a freestanding bath, and sometimes connected to a walk-in wardrobe to form a master suite. In Auckland 2026, master ensuite additions are the single most requested bathroom upgrade.
How long does a bathroom renovation last?
A properly designed and waterproofed Auckland bathroom renovation should last 15–25+ years before needing significant work. The biggest factor in longevity is the unseen work — membrane waterproofing, plumbing pipe quality, ventilation. Tiles, fittings, and finishes can outlive their style. Choosing classic neutral tile and quality stone or composite surfaces holds value at resale.
What areas of Auckland do you service for bathroom renovations?
Add Value Renovations completes bathroom renovations across greater Auckland — including Remuera, Epsom, Parnell, Newmarket, Mt Eden, Ponsonby, Herne Bay, Devonport, Takapuna, St Heliers, Howick, Pakuranga, and surrounding suburbs. We are based in Newmarket and work across the North Shore, East Auckland, and the Central and Western Suburbs.
What does the Master Build 10-Year Guarantee cover for a bathroom?
The Master Build 10-Year Guarantee covers defects in materials and workmanship, structural defects for 10 years, and loss of deposit. For bathrooms specifically, this includes waterproofing failure — meaning if the membrane fails within 10 years, the repair is covered. See the full guarantee details.
How do I get started with a bathroom renovation in Auckland?
The easiest first step is a free, no-pressure phone consultation — usually 15–30 minutes. We’ll ask about your existing bathroom, your goals, your budget range, and timeline, then give honest advice on what’s possible. From there, we arrange a site visit and develop a concept design with a transparent cost estimate. Call us on 09 393 5658 or use the online estimator.
