Frequently Asked Questions About Shower Waterproofing in Stuart Park
How much does shower waterproofing cost in Australia?
Shower waterproofing costs $30–$80 per square metre in Australia, covering the shower floor, hobs and walls up around the shower recess. A 15 litre membrane runs $59–$262, typically around $110, plus primer at $20–$55 and reinforcing bandage at $38–$52 per roll for corners and wall-floor junctions.
How many coats of waterproofing membrane does a shower need?
Most shower waterproofing needs two full coats of membrane over the floor and walls, with a reinforcing bandage embedded at joints, corners and the floor waste before the coats go on. Each coat needs to dry before the next, usually a few hours apart. A 15 litre membrane tin, enough for a full shower recess, costs $59–$262.
Can I retile a shower without redoing the waterproofing?
It's risky. Removing shower tiles without damaging the membrane underneath is difficult, and any scratch, puncture or lifted corner in the old membrane becomes a hidden leak path once new tiles go down. Most licensed waterproofers recommend replacing the membrane whenever a shower is retiled. A fresh membrane costs $59–$262 for a 15 litre tin, typically around $110.
How much does bathroom waterproofing cost in Australia?
Waterproofing a standard shower costs $300–$600. A full bathroom including shower, floor, and bath area costs $500–$1,200. Balcony waterproofing costs $80–$150/m². These are labour costs only — materials add $50–$200 depending on the membrane system used.
Do I legally need to waterproof my shower?
Yes — AS 3740 (Waterproofing of domestic wet areas) is mandatory under the National Construction Code. All showers, bath surrounds, laundries, and balconies must be waterproofed to this standard. Failure to comply can void home insurance claims related to water damage.
How long does waterproofing last in a shower?
A quality waterproofing membrane correctly installed should last 10–15 years minimum. Cheap products or incorrect installation fail much sooner. The grout and tile system on top doesn't waterproof the shower — the membrane underneath does. Grout cracks don't mean the waterproofing has failed.
How do I know if my shower is leaking?
Signs include damp patches on adjacent walls or floors, mould behind tiles, peeling paint, efflorescence (white mineral deposits), soft or spongy tiles, or a musty smell. A licensed waterproofer can perform a flood test to confirm leakage before expensive rectification work begins.
Can you waterproof over existing tiles?
Generally not recommended for showers. If the existing tiles are sound and firmly bonded, a liquid membrane can be applied over them in some scenarios. However, if there are any cracked, hollow, or loose tiles, these must be removed and the substrate repaired before new waterproofing is applied.
