Bathroom waterproofing services for Melbourne homes

The right approach depends on the bathroom's current condition. It may involve a full wet-area rebuild, investigating a leaking shower or re-waterproofing an existing room after earlier work has failed.

For the factors that shape price once the bathroom condition is understood, see the bathroom waterproofing cost guide. To send details straight through, use the contact page.

1. Bathroom waterproofing

This applies when a bathroom is being restored and the whole wet area needs a new waterproofing membrane before tiles and finishes go back on. It usually forms part of a broader restoration rather than a repair to a small area.

When this service may fit

• The bathroom is being stripped as part of a renovation or restoration
• A new membrane is planned across the shower, floor and other wet-area surfaces
• Plumbing, tiling or fixture work is being planned at the same time

Information and photos that help

• Approximate bathroom size and layout (shower, bath, vanity, WC)
• Photos of the current state, including the floor and any wet-area walls
• Whether tiles are already off or still in place

What happens next

Send the bathroom size, layout and current stage. If the work appears suitable, we can arrange a site visit before confirming the scope.

2. Leaking shower assessment

This applies when a shower or bathroom appears to be leaking and the cause needs to be checked before work is planned. The first question is where the water is actually coming from — the waterproofing, the tiles and grout, or a plumbing fixture.

Common signs to describe

• A damp patch on a wall or ceiling near or below the bathroom
• Water pooling outside the shower or tracking along grout lines
• Movement or hollow-sounding tiles in the shower recess

Information and photos that help

• When the leak was first noticed and how often it shows
• Photos of the affected area, ideally including the shower and any stained neighbouring surface
• Any previous repair attempts or recent bathroom work

What happens next

Tell us where the water appears and when it happens. Photos can help us prepare, but a site visit may be needed to work out whether the source is waterproofing, tiles and grout, or plumbing.

3. Re-waterproofing existing bathrooms

This applies when a bathroom was waterproofed previously but the membrane appears to have failed. Existing tiles and finishes usually have to come up before a new membrane can be laid over a properly prepared substrate.

When re-waterproofing may fit

• Damp or staining has returned after earlier repair work
• Tiles or finishes are being removed to expose the substrate
• The existing membrane or substrate appears damaged once the area is opened

Information and photos that help

• Rough age of the existing bathroom and any known history of previous waterproofing
• Photos of the current substrate if tiles are already off
• Any related work — plumbing, tiling, fixtures — you expect will be involved

What happens next

Tell us what work has already been done and what is now exposed. If re-waterproofing appears suitable, we can arrange a site visit before confirming the scope and any related trades.
