Key Interiors · Est. Auckland
Key Interiors designs and builds luxury bathrooms and ensuites across Auckland — tiling, custom vanities, tapware and lighting, delivered by one team with a fixed price after design.
A great bathroom does something quiet but powerful — it makes the start and end of every day feel a little more considered. A tired, leaky, badly-laid-out one does the opposite, every single morning.
Key Interiors is a true design-and-build studio. We handle your bathroom renovation from the first concept sketch to the final coat of paint — design, waterproofing, tiling, custom vanities, plumbing, electrical and installation, all under one roof. No juggling designers, tilers and trades. No surprise costs halfway through. One accountable team, one fixed price, one beautiful result that lasts.

A great bathroom is half what you see and half what you don't — and we obsess over both.
We make small Auckland bathrooms feel twice the size — the right position for the shower, vanity and toilet, and walkways that actually work.
The part you never see but matters most. Waterproofed to NZ standards with proper falls and sealed junctions, then tiled to a flawless finish.
Bespoke vanities and joinery built to fit your space — soft-close drawers, smart storage and stone tops that handle daily life.
Frameless glass showers, walk-in wet rooms and freestanding baths — designed to feel like a retreat and built to drain and seal perfectly.
Quality tapware, underfloor heating and heated towel rails — the warm-underfoot details that turn a bathroom into a daily luxury.
Layered, flattering lighting, mirror and ventilation done right, and a master-painted finish from our own team.
From restored villa bathrooms to spa-like luxury ensuites — designed to suit your home, not a showroom.
Heritage-sympathetic detail, timeless tiles and warm fixtures — perfectly at home in an Auckland villa or bungalow.
Clean lines, large-format tiles and frameless glass for a calm, hotel-like bathroom that feels effortlessly current.
Freestanding baths, statement stone, underfloor heating and bespoke detailing — an ensuite built to feel like a private retreat.

Every bathroom is different — but here's an honest 2026 starting guide for what Auckland homeowners are actually spending.
New vanity, tapware, tiling and fixtures in the existing layout — a fresh, modern bathroom without moving plumbing.
Full retile, custom vanity, frameless shower, new toilet, quality tapware, waterproofing and lighting — done properly.
Freestanding bath, underfloor heating, premium large-format tiles, a wet-room layout and high-end tapware.
Auckland bathrooms typically run 10–20% above the national average, around $1,800–$2,900 per m². Keeping the toilet, shower and vanity in place saves thousands; moving plumbing adds cost. After your design phase, you get a fixed price — so the number you sign off is the number you pay.
Book a free, no-obligation Bathroom Roadmap. We come to your home, measure up, understand how you want to use the space, and give you a layout direction, honest scope and budget range — so you start with a plan, not a guess.
Once you sign off your design, your build price doesn't move — we wear the difference, not you. Every bathroom is waterproofed to standard and finished to our master-painter standard, and if a detail isn't right at handover, we make it right. That's the deal.
We deliberately take on only a handful of bathrooms each month so yours gets our full attention — Auckland calendars book out weeks ahead.

Most Auckland bathroom renovations sit between $25,000 and $35,000 for a full renovation with new tiling, a custom vanity, a frameless shower, quality tapware and waterproofing. A lighter refresh can start from around $15,000, while luxury bathrooms with freestanding baths, underfloor heating and premium finishes range from $45,000 upwards. After your design phase, we give you a fixed price — so you know exactly what you're investing before any work begins.
On site, most bathroom renovations take 2 to 4 weeks from demolition to final handover, including time for waterproofing and tiling to cure properly. With design and material lead times, it's worth planning for around 6 to 10 weeks end to end. Your dedicated project manager gives you a clear timeline before the build starts.
Many like-for-like bathroom renovations don't require consent. You'll generally need it if you're adding a new bathroom, moving drainage, or making structural changes. We'll tell you up front whether your project needs consent and handle the process for you if it does.
Waterproofing is the part you never see but matters most. We waterproof to New Zealand standards before any tiling goes down, with proper falls to the drain, sealed junctions and quality membranes — then finish to a master standard. It's the difference between a bathroom that lasts decades and one that fails in a few years.
Yes. Keeping plumbing in the same position is the most cost-effective option, but we regularly reconfigure layouts when it makes the space work better. Moving a toilet or shower adds cost because it means new drainage, and we'll show you the trade-offs clearly in your Bathroom Roadmap before you decide.
We design and build bathrooms and ensuites right across Auckland — from the central villas of Point Chevalier, Mt Albert, Grey Lynn and Ponsonby to the eastern suburbs, North Shore and the wider region.
Auckland homeowners trust Key Interiors to design and build bathrooms done right — one team, one fixed price, waterproofing you can count on. Start with a free Bathroom Roadmap.
