How we waterproof a toilet, step by step
A lasting fix means replacing the waterproofing layer, not just sealing the grout. Our site team follows a fixed sequence.

- Hack the floor tiles and screed down to the slab, and the lower wall tiles where needed
- Repair the slab, seal pipe penetrations and the floor trap
- Lay the waterproofing membrane on the floor with upturns onto the walls
- Flood test for at least 24 hours to confirm it is watertight
- Screed, re-tile, grout and refit, then hand over with the 5-year warranty

How much does toilet waterproofing cost in Malaysia?
Toilet or bathroom waterproofing costs about RM2,500 to RM6,000 per bathroom in 2026, including hacking the old tiles, a new membrane, flood test and re-tiling, with a 5-year warranty. Size, wall tiling removed, tile choice and access affect the price. The exact figure is confirmed after our free inspection.
Why is my toilet leaking to downstairs?
The most common reason is a failed waterproofing membrane under the floor tiles, often around the floor trap, shower area or pipe penetrations. A cracked water pipe or loose floor trap can cause the same stain. A stain that appears after showers, not after rain, points to the bathroom.
Can bathroom waterproofing be done without hacking tiles?
Some products are applied over tiles or into grout and may slow a minor leak, but they rarely fix a failed membrane underneath. For a lasting repair with a 5-year warranty, the tiles and screed are hacked to the slab and a new membrane is laid. Our technician explains the options on site.
