The shower recess takes more water than any other surface in your home, so it is the first place a poor membrane will fail. Water finds its way through cracked grout, gaps around the waste or a missing bond breaker and soaks into the bedding, framing and floor below.
We specialise in shower waterproofing for new bathrooms and leaking shower repairs across Sydney — including modern hobless (step-free) showers that demand precise falls and detailing.
Signs you need shower waterproofing
- Water appearing outside the shower screen after use
- Stained or peeling paint on the wall behind the shower
- Dark or crumbling grout lines at the base
- Tiles that sound hollow when tapped
- Damp carpet or timber floor in the next room
- Water marks on the ceiling below an upstairs shower
Shower waterproofing done to last
A shower needs more than a coat of membrane. The detail at the waste, the junction between walls and floor, the hob or step-down and the tap penetrations are where leaks begin. Our process treats each of these with reinforcement and flexible sealants designed to move with the building.
Hobless and level-entry showers
Step-free showers look great and are easier for people with limited mobility, but the whole floor must be graded correctly and a waterstop or linear drain installed at the shower boundary. We work with your builder at the framing stage to set down the floor, plan the falls and select a compatible drain system.
Leaking shower repair options
- Full strip and re-waterproof — the permanent fix when the membrane has failed
- Targeted regrout and silicone — suitable for minor, surface-level issues only
- Leak investigation — moisture mapping to confirm the source before any demolition
We will always tell you honestly which option suits your situation. Quick-fix sealers sprayed onto grout may hide a problem for a few months, but they do not replace a failed membrane.
Our shower waterproofing process
-
1
Leak diagnosis
Moisture readings and a water test confirm whether the leak is from the membrane, waste, grout or plumbing.
-
2
Strip back
Tiles and bedding are removed from the affected area back to a sound substrate.
-
3
Falls & waste
We correct falls to the waste and install a puddle flange or linear drain as required.
-
4
Reinforce & membrane
Junctions are bond-broken and reinforced, then two coats of membrane applied to the full shower area.
-
5
Flood test & tile-ready
We flood test before handing over to your tiler, with photos for your records.
