Bathroom Renovation in Auckland: The Complete Tiling Guide

What Does the Tiling Side of a Renovation Involve?

Most people picture a tiler turning up with boxes of tiles. The real sequence looks like this:

1. Strip-out — old tiles, fittings and (often) the substrate come out.
2. Substrate preparation — surfaces are made sound, flat and ready. On older Auckland villas this can be the biggest job of all.
3. Falls and levelling — shower floors are shaped so water runs to the drain, not the corner.
4. Waterproofing — membrane applied to the wet areas, with proper curing time between coats.
5. Tiling — layout planned first (so cuts land where you won’t see them), then laid.
6. Grouting and sealing — the finish that decides how the room looks in year ten, not just day one.

Each step depends on the one before it. When a renovation goes wrong, it’s almost never the tiles — it’s a rushed step underneath them.

Where Tiling Fits in the Renovation Order

Waterproofing First — the Step You Never Skip

Under the New Zealand Building Code (clause E3, Internal Moisture), wet areas must be protected so moisture can’t damage the building. In practice that means a properly installed waterproofing membrane under and behind your tiles — applied to a prepared surface, with each coat given its full curing time. This is the part nobody sees and everybody depends on. A failed membrane means lifting brand-new tiles to fix it — the most expensive way to learn the lesson.

Marko’s tip: “Ask to see the waterproofing before it’s tiled over. A good tiler will be proud to show you. If someone wants to tile the same day the membrane went on, that’s your cue to ask questions.”

We’re certified applicators of approved systems (ARDEX, Mapei) and Marko is an approved PS3 Producer Statement author — for eligible projects we can provide the formal documentation that gives builders, councils and homeowners confidence the waterproofing meets the Building Code.

Choosing Tiles for an Auckland Bathroom

A few decisions shape both the look and the budget:

• Porcelain vs ceramic. Porcelain is denser and more durable — usually the right call for floors; ceramic suits walls and tighter budgets. See our full porcelain vs ceramic guide →
• Tile size. Large-format means fewer grout lines and a calm, modern look, but demands a flatter substrate and more careful handling.
• Slip resistance. For bathroom floors, ask about the tile’s slip rating; smooth gloss tiles that look beautiful on a wall can be wrong underfoot in a wet room.
• Grout colour. The cheapest way to change a bathroom’s character — matching grout calms a space, contrasting grout makes the layout a feature.
• The details. Shower niches, mitred edges and centred layouts are what make a bathroom look designed rather than assembled. They cost planning, not just money.

Bring your tiler in before you buy the tiles. Ten minutes of advice on sizes and layout can save you an expensive re-order — and a compromise you’ll look at every morning.

How Long Does a Bathroom Renovation Take?

The honest answer is that it varies — the time the tiling and waterproofing take depends on the size of the room, the condition of the substrate and the complexity of the layout. Waterproofing adds necessary days on top, because membranes need curing time between coats and rushing that step is how leaks happen. Rather than quote a number that won’t match your home, we give you a realistic timeline when we quote the job. The full renovation, with all trades, runs longer again.

One honest note: good tilers are booked ahead. If your renovation has a fixed deadline — a baby on the way, guests at Christmas — lock your tiler in early rather than hoping the dates work out.

What Does It Cost?

There’s no single number: the same-sized bathroom can cost very differently depending on prep, waterproofing and tile choice. Rather than quote averages that won’t match your home, we’ve written an honest breakdown of what actually drives the price — and how to compare quotes properly. Bathroom Tiling Cost in Auckland →

How to Choose Your Tiler

Whoever you hire, ask these questions:

1. Who does the waterproofing, and are they certified? You want one team responsible for the membrane and the tiles — no gaps for blame to fall into.
2. Can you provide a PS3 Producer Statement? For eligible work, it’s the formal sign-off that the waterproofing was installed to the Building Code.
3. Are you insured, and do you guarantee your workmanship?
4. Can I see recent local work and reviews? Real photos and named reviews beat any sales pitch.

For what it’s worth, here’s how one Auckland client described working with us — after we renovated and tiled four bathrooms on a tight commercial deadline:

“Couldn’t recommend enough. Marko went above and beyond to ensure our fairly large commercial tiling needs were met (they helped us tile and renovate 4 bathrooms in a very short space of time), and dealing with him and Valentina was an absolute pleasure. No problem was too difficult, and the whole Tarara Tiling team got the job done on time and on budget. Cheers!” — Adam C., Google review

Frequently asked questions

Do I need a building consent to renovate my bathroom in Auckland?

Often not — like-for-like replacement of fittings and finishes is generally exempt building work. Moving plumbing, altering the structure or changing the use of the space can require consent. It’s always best to check with Auckland Council or your builder before you start.

Can you tile over existing tiles?

Sometimes — if the existing tiles are sound, well bonded and the extra height works with your doors and fittings. In wet areas we usually recommend stripping back, because tiling over the top means trusting waterproofing you can’t see. We’ll give you a straight answer on site.

Can I add underfloor heating during a renovation?

Yes — a renovation is exactly the right time, because the floor is already coming up. It has to go in before the tiles, so mention it early. Underfloor heating →

Does the tiler do the plumbing too?

No — plumbing is a licensed trade of its own. We work in sequence with your plumber: they rough-in, we waterproof and tile, they fit off. On builder-run projects that coordination is handled for you.
