Bathroom Tiling & Waterproofing Brisbane: What Should Be in the Quote

Published 20 September 2026

What a Brisbane tiling and waterproofing quote should itemise - and what “tiles only” usually hides. Ask each renovator to spell the pair out.

Tiling and waterproofing are sold as a pair on real Brisbane wet-area jobs because tiles hide the membrane, and the membrane decides whether the tiles last.

This page is quote anatomy: what a good combined quote itemises, what “tiles only” skips, and which sequence checkpoints to ask about. It is not a DIY tiling tutorial.

Cannibalisation note: standards, Form 43/30 and certificate nuance live on bathroom waterproofing in Brisbane. This page is the line-item and sequence lens.

Brisbane Bathrooms HQ matches requests. We do not tile, waterproof, certify or warrant work. Homepage language to keep: the quiet work that matters most - ask each renovator how they warrant it.

Why “tiles only” and “tiling + waterproofing” are different jobs

A retiling quote that never opens the wet zone is a different job from a shower recess that needs a membrane reset. If tiles are coming off, ask whether the membrane will be replaced - do not assume.

If you are still choosing shower-zone vs full room, shower vs full renovation.

Line-item anatomy (what to demand in writing)

Use this as a column checklist across quotes (comparison method):

Should be namedWhy it matters
Strip-out and disposalOld tiles and substrate have to go somewhere
Substrate repair / sheet / screed / fallsTiles fail on a bad base
Waterproofing - who, licence, areas, system“Included” is not a spec
Written proof at handoverCertificate and/or membrane record
Tile supply vs labourPC allowances hide cheap totals
Adhesive, grout, silicone, trimsFinishing is not free
Niches, junctions, penetrationsWet-area detailing
Shower screen / hob / waste interfaceWhere leaks start
ExclusionsWhat you will pay later
Variation pathWhat happens when the substrate surprises you

Ask each renovator to itemise tiling and waterproofing. Combined packages are fine when those lines are still visible.

Sequence checkpoints (process, not a diary)

Homeowners can ask, without becoming site supervisors:

  1. Substrate and falls ready for membrane.
  2. Membrane applied by the named person.
  3. Cure per product data sheet and site conditions - not the tiler’s preferred start day. We do not invent cure days.
  4. Inspection / record before tile-over.
  5. Tiling, grout, silicone, screen.

Hiring questions to reuse: 12 questions.

Allowances, PC tiles, and “cheap” m² rates

If Quote A supplies tiles and Quote B uses a low PC allowance, you are not comparing the same bathroom. Align the tile specification or add the gap back in. We do not publish typical m² rates.

Red flags specific to tiling + waterproofing packages

  • “Tiles include waterproofing” with no named waterproofer.
  • No exclusions list.
  • No mention of falls, wastes or shower-zone extent.
  • Pressure to tile immediately after membrane with no cure conversation.
  • Contract entity ≠ licence entity.

We do not invent fall ratios, coat counts, inspection fees or price bands.

FAQs

What should be in a bathroom tiling and waterproofing quote in Brisbane?
Strip-out and substrate prep, named waterproofing (who, areas, system, written proof), tile supply vs labour, adhesive/grout/silicone, falls and waste details at a high level, shower screen interface, exclusions, and any tile PC allowances.
Why shouldn’t I accept a “tiles only” bathroom quote?
Tiles hide the membrane. A tiles-only number often skips membrane reset, substrate repair, waste, and certification language. If the wet area is being opened, treat tiling and waterproofing as a pair.
Does retile bathroom Brisbane mean new waterproofing?
Not automatically - and that is the risk. If tiles are coming off in a shower zone, ask whether the membrane will be replaced, inspected, and documented. Do not assume old waterproofing is fine because the quote is cheap.
Who should apply the membrane vs who tiles?
Ask for names and licence classes. Waterproofing is its own QBCC licence class. The tiler may or may not be the waterproofer. Confirm credentials with each provider.
What is a provisional sum or PC for tiles?
A placeholder for tiles (and sometimes labour) you have not locked. If one quote allows a cheaper tile than another, the totals are not comparable until you align the allowance.
Should waterproofing be a separate line from tiling?
Yes if you want to compare quotes. Combined packages are fine when the waterproofing lines are still named. “Tiles include waterproofing” with no detail is not a specification.
What sequence should I ask about before tiling starts?
Substrate and falls ready; membrane applied; cure per product data sheet; inspection/record before tile-over; then tiling, grout and silicone. No invented day counts.
How does Brisbane Bathrooms HQ matching help compare tiling quotes?
We match bathroom requests; we do not tile or waterproof. Free form, contact first, named yes, at most three. Ask each company to itemise tiling and waterproofing, then verify licences yourself.
