Villa Bathroom Renovations in Auckland
Alchemy Bathroom Renovations Auckland renovates villa bathrooms in Auckland character homes, from main bathrooms and ensuites to separate toilets and laundries. The work covers the parts a villa hides, including levelling and re-sheeting the timber floor, replacing old galvanised pipe and building tiled showers over timber. Nick McKelvie leads each job as a Licensed Building Practitioner (BP1021390) and a registered producer statement author for waterproofing (PSA127420), and his team has spent 30 years renovating bathrooms across Auckland, more than 1,200 of them.
Villas in Ponsonby, Grey Lynn, Devonport and Mt Eden were built with high ceilings, sash windows and timber floors on piles. Nick keeps the features you want to keep and replaces what a century of moisture has damaged underneath them. The floor and the pipes are rebuilt first, so the new bathroom sits on sound timber. Every villa bathroom starts with a free site visit, and the written quote that follows lists every trade and every fixture.

Villa Bathroom Renovation Work We Do in Auckland
Six parts of a villa bathroom job. Most villas need several of them at once.

Full Villa Bathroom Renovation
We renovate villa bathrooms in the room they already occupy, which keeps the waste and the window where the house expects them.
The room comes back to the framing, the floor is levelled, and a new waterproofing membrane, shower, vanity and ducted extractor go in.
Tell us if the bathroom was altered between the 1950s and the 1980s. Relined walls from that period may need testing for asbestos.

Floor Levelling and New Subfloor
An Auckland villa floor that bounces or slopes gets levelled and re-sheeted by us before anything else, because tiles and a waterproofing membrane crack on a moving floor.
Rotten joists are replaced, the floor is packed level and re-sheeted, and the subfloor is checked for ventilation.
Changes to joists or piles are restricted building work, done or supervised by Nick as a Licensed Building Practitioner.

Tiled Showers on Timber Floors
Our tiled showers on villa timber floors get their fall built into the framing, so the waterproofing membrane sits on a floor that already drains.
A tiled wet-area shower needs a building consent in Auckland, and Nick issues the PS3 for the waterproofing.
Ask about a level-entry shower if you want the hallway and the bathroom floor to meet flush.

Old Pipework Replacement
Old galvanised pipe in an Auckland villa rusts from the inside, and we replace it back to a sound connection during the strip-out.
Low flow and brown water at the first tap in the morning are the usual signs. Doing the work now means no new tiled wall gets opened later.
Tell us if the house still has a low-pressure hot water cylinder in the ceiling.

Keeping Villa Character Features
Keeping the high ceiling, the sash window and the deep skirtings is part of every villa bathroom we plan, and the new work fits around them.
A tall room needs a larger extractor to move the same steam, and a sash window near the shower needs a sill that sheds water.
Tell us if the house sits in the Special Character Areas overlay before any window or exterior change is planned.

Villa Toilets and Laundries
Villa toilets and back-porch laundries get renovated by us alongside the bathroom or on their own.
A laundry floor gets a waterproofing membrane and a floor waste, so a burst hose drains away. A separate toilet often needs the same floor work as the bathroom next to it.
Recent work includes a Ponsonby villa with a bathroom, two toilets and a laundry with a custom tiled shower.

How a Villa Bathroom Renovation Runs With Alchemy
Five steps, with the floor and pipes rebuilt before anything new goes in.
Free Villa Bathroom Site Visit
Nick measures the bathroom, checks the floor for bounce and slope, looks at the pipework he can see, and notes the ceiling height and windows. No charge and no obligation.
Written Quote and Layout
The quote lists every trade, every fixture and the build order. Where the layout changes, the measured plan is settled at this step.
Strip-Out, New Floor and Pipework
The room comes back to the framing. The floor is levelled or re-sheeted, rotten joists are replaced and old galvanised pipe is swapped for new.
Waterproofing Membrane, Then Fit-Out
The waterproofing membrane goes on and cures, then the tiles, vanity, shower, toilet and extractor go in. On a consented job Nick issues the PS3.
Villa Bathroom Handover
You walk the finished bathroom with Nick and every fixture is run. The waterproofing carries Alchemy's 15-year guarantee from handover.

Published villa bathroom pricing
Villa Bathroom Renovation Cost in Auckland
$22,000 to $35,000
That is what a villa bathroom renovated in its existing room costs with Alchemy, including floor levelling and new pipework.
A villa bathroom costs more than a newer bathroom of the same size, because the floor, the pipes and the walls usually need rebuilding before the new work starts.
These ranges are a starting point for your budget. Nick puts a fixed figure on your villa bathroom in writing after the site visit.
| Villa job | Range | What sits in it |
|---|---|---|
| Villa bathroom, same room and layout | $22,000 to $35,000 | Floor levelling and re-sheet, new pipework, waterproofing membrane, shower, vanity, toilet and ducted extractor |
| Villa bathroom with a new layout | $30,000 to $45,000 | Everything above plus new drainage under the floor, a relocated shower or toilet and consent inspections |
| Villa bathroom with character finishes | $45,000 to $65,000+ | Freestanding bath, underfloor heating, heritage-style tapware, stone or large-format porcelain |
| Villa toilet or laundry | Quoted per job | Priced on the floor work, the plumbing run and whether a shower goes in |

What Moves the Price of a Villa Bathroom
Villas vary more than newer homes. These five things set where yours lands.
Floor condition
A floor that only needs packing and a new sheet is a small part of the job. Rotten joists and piles add framing work before the bathroom starts.
The pipework
Galvanised pipe that runs beyond the bathroom walls adds plumbing time and access work under the house.
Moving fixtures
New drainage for a relocated shower or toilet runs under the floor, so subfloor access sets the time it takes.
Asbestos in old linings
A suspect lining is tested first. Removing more than 10 m² of non-friable asbestos needs a licensed removalist.
Ceiling height and finishes
High villa ceilings mean more wall to tile and a bigger extractor. Heritage-style tapware and stone move a job up the range.
Why villa owners call Alchemy
Why Auckland Villa Owners Choose Alchemy for the Bathroom
A villa bathroom fails at the floor and the pipes first. These six things deal with both.
An LBP for the floor under the bathroom
Nick McKelvie holds LBP number BP1021390. Replacing villa joists or piles is restricted building work, and he does it or supervises it.
A PS3 for waterproofing over timber
Nick is a registered producer statement author, PSA127420. On a consented villa bathroom he issues the PS3 for the waterproofing laid over the timber floor.
15 years on the waterproofing membrane
Alchemy guarantees the waterproofing membrane for 15 years from handover, on a floor that has been levelled and re-sheeted first.
Extractors sized for high ceilings
Every extractor Alchemy fits is ducted to open air and sized for the room, and a villa bathroom has more air to move than most.
Hidden damage priced before it is replaced
The strip-out in a villa can uncover rot or old pipe the site visit could not see. You get the price for that work and approve it before it goes ahead.

What sits under a villa bathroom
Damp, Asbestos and Timber Floors in Auckland Villas
Villa suburbs carry more damp than new ones. At the 2023 Census, 24.6% of occupied homes in Grey Lynn West and 23% in Ponsonby West reported being damp always or sometimes, against 2.2% in Hobsonville Point Catalina Bay. In a villa bathroom, moisture from the shower and moisture from under the floor meet in the same timber, so Nick checks the subfloor ventilation along with the room.
A villa bathroom relined between the 1950s and the 1980s can have asbestos in the wall sheet or the vinyl. WorkSafe's asbestos licensing rules allow up to 10 m² of non-friable asbestos to be removed without a licence over the whole project, with controls in place. More than that needs a Class B licence, and any friable asbestos needs a Class A licence. A suspect lining is tested before the strip-out starts.
Timber floors move with the seasons. Tiles in a villa go down over a new sheet floor fixed to the joists, with movement joints at the walls, because grout cracks where a floor flexes.

Reviews From Auckland Villa and Bathroom Clients

We liked Nick’s approach of starting with a site meeting to discuss our goals and the practicalities of the project. Nick was great at problem solving and communication. There was a significant delay with council inspections, but once they were done the work proceeded with great pace and the end result has been superb.
