What counts as a bathroom refresh?
A refresh keeps the existing waterproofing, substrate and layout, and renews the surfaces you see: paint over moisture-tolerant preparation, tiling repairs, grout, silicone and fittings. It is the smaller, faster job, and it is only sensible when what sits behind the tiles can be trusted.
What counts as a full bathroom renovation?
A full renovation strips the room back to the substrate. It usually changes the layout, moves fixtures or replaces the substrate entirely, and it installs a new waterproof membrane that has to cure, and is often inspected, before tiling starts.
Plumbing or electrical changes for the new layout are confirmed and sequenced before tiling and painting, so a full renovation involves more trades working in a set order.
Which problems point to a refresh, and which to a renovation?
Wear on the surfaces points to a refresh, and anything that means the waterproofing cannot be trusted points to a renovation. These are the conditions a site visit looks for, and what each one usually means.
| What you find | What it usually points to |
|---|---|
| Sound tiles and grout, tired paint and silicone | A refresh. The waterproofing is doing its job, so the visible surfaces are the work. |
| Mould on the ceiling or walls | Fix the ventilation or moisture source first. A refresh can work once that is dealt with. |
| Moisture damage behind or around the tiles | The existing waterproofing cannot be trusted, which points to stripping back to the substrate. |
| Older tiling laid straight onto the old substrate | A choice: reuse it as the smaller scope, or strip back to a compliant waterproof base. |
| Moving the shower, vanity or toilet | A full renovation, with plumbing and electrical changes confirmed before tiling. |
Based on the wet-area sequence described on our bathroom renovations page. A room can show more than one of these, which is why the scope is written after the room has been seen.
Why does the waterproofing decide it?
Because it is the one part of a bathroom a refresh cannot fix. The Building Code's E3 internal moisture clause requires wet-area surfaces to be impervious and easily cleaned, and new paint, grout or silicone does not make failed waterproofing sound again.
Many older Auckland bathrooms were tiled directly over a substrate that would not meet a current wet-area waterproofing approach. Reusing that substrate is a different, smaller scope than removing it and starting from a compliant waterproof base, and the two should be priced as different jobs.
Can a refresh fix a mouldy bathroom?
Only once the moisture source is dealt with. A bathroom that traps moisture keeps stressing paint, grout and silicone however well it was finished, and painting over mould without fixing ventilation tends to bring the same mould back through the new coat.
Why does a full renovation take longer?
Mostly because of sequence. The membrane goes down and cures before tiling, tiling and wet work come before painting, and any plumbing or electrical change comes before all of it. Each trade has to finish before the next can start without damaging its work, and cure time cannot be compressed without risking the finished room.
Why is a site visit the way to tell?
Photos rarely show moisture damage, the transitions between surfaces, access limits or how fixtures relate to the finishes. The visit is how the scope separates what is known before work starts from what depends on the condition found under existing tiles, linings or paint.
Where does painting fit in either job?
Near the end of both. Ceilings and painted walls get moisture-tolerant preparation and are usually sequenced after tiling and wet work, so the finish is not marked by the rest of the job.
