Waterproofing is the one part of a bathroom you never see and cannot afford to get wrong. It goes on before the tiles, so once the job is finished the membrane is hidden for good. If it fails, the first you hear of it is a musty smell, a stain on the ceiling below, or a repair bill that runs into the thousands once tiles come up and framing has to be replaced.
Tilers Adelaide connects you with vetted, licensed local waterproofers who tank wet areas properly and to AS 3740, the Australian Standard for waterproofing of domestic wet areas. Tell us about your shower, bathroom or balcony and we will match you with trusted Adelaide tradespeople who cover your suburb, then you compare free, no-obligation quotes and choose.
We are a referral service, not a waterproofing contractor. Our only job is finding you a licensed waterproofer you can trust to get the membrane, falls and drainage right the first time, and making it easy to compare a few quotes side by side.
What the tilers we refer you to can help with
Shower recesses
The highest-risk zone in the house, tanked properly with the right falls to the waste before tiling.
Full bathrooms and ensuites
Floors, hobs, wall junctions and penetrations sealed so water stays where it belongs.
Laundries and powder rooms
Smaller wet areas that still need a compliant membrane around the trough, taps and floor waste.
Balconies and terraces
Exposed decks and balconies that face Adelaide sun, rain and movement, waterproofed to hold up outdoors.
Failed or leaking wet areas
Stripping back a shower or bathroom that is leaking and re-tanking it so the problem is fixed for good.
Compliance and certificates
Work done to AS 3740, with a waterproofing certificate where your build or insurer needs one.

Why waterproofing is the job you cannot cut corners on
A shower leak is the most common and most expensive fault in an Australian bathroom. Because the membrane is buried under the tiles, a poor job hides itself for months or years while water quietly tracks into the wall frame, the subfloor and the room next door. By the time it shows, you are not repairing a membrane, you are repairing rotten timber, swollen plaster and lifting tiles as well.
That is exactly why the waterproofers we refer earn their keep. Getting it right means the correct membrane for the surface, primer where it is needed, proper falls to the floor waste, and careful detailing at the tricky points: the hob, the wall to floor junction, the tap and shower penetrations, and the drain. Cheap operators rush these and skip the drying time between coats. A good one does not.
- Correct membrane and primer for the substrate, at the specified thickness
- Bond breakers and reinforcing at wall junctions, corners and hobs
- Falls set to the floor waste so water drains rather than pools
- Penetrations at taps, drains and the shower sealed and detailed
- Full curing time between coats before any tile goes down
Waterproofing to Australian Standards in South Australia
In South Australia, waterproofing a wet area is regulated work. AS 3740 sets out how domestic wet areas must be waterproofed, and the person doing it needs to be appropriately licensed for it, not just handy with a roller. This is not a job to hand to whoever is cheapest or to attempt yourself between other trades.
Every waterproofer we refer is licensed for the work and carries insurance, so the membrane is done to standard and your home is covered. Where your builder, council or insurer needs a waterproofing certificate for the wet area, the tradesperson can provide one. That paperwork matters when you sell, renovate or ever need to make a claim.
Why compare quotes for waterproofing
Waterproofing a single wet area in Adelaide typically runs about $500 to $1,500, depending on the size of the room, the number of penetrations and how much prep the surface needs. It is a small line item next to the tiling, but it is the one that protects everything else, so the cheapest quote is rarely the one to chase.
Comparing a few quotes lets you see who is pricing the job properly and who is skimming. We make that easy by matching you with vetted, licensed waterproofers who quote on the same wet area, so you are comparing like with like and can choose on trust, not just price.
What will it cost?
Waterproofing a wet area in Adelaide typically runs about $500 to $1,500, depending on room size, penetrations and prep. It is usually done as part of a bathroom job. See the cost guide or try the waterproofing estimator for an indicative figure.
