Why Is My Shower Leaking Through the Floor?
A shower that’s leaking through the floor is one of the most common and most damaging problems New Zealand homeowners face. Left untreated, water seeps into your subfloor, causes structural rot, and turns a simple repair into a costly renovation.
Why it happens
The most common causes of water leaking through the shower floor:
- Failed waterproof membrane — the layer beneath your tiles breaks down over time (typically after 10–15 years in New Zealand homes)
- Cracked or missing grout — lets water sneak through gaps between tiles, especially at the floor-wall junction
- Deteriorated silicone — silicone around the shower base and wall junctions hardens and pulls away
- Poor original installation — many New Zealand homes built in the 1990s and 2000s had substandard waterproofing practices
How to Tell If Your Shower Is Leaking
- Damp or soft spots on the ceiling below your bathroom
- Musty smell in adjacent rooms or hallways
- Discolouration or bubbling paint near the shower base
- Tiles that feel hollow or shift underfoot
- Mould appearing on walls adjacent to the shower
The ShowerFix Approach
We use a non-invasive leak detection process, including moisture meters and flood testing, to pinpoint exactly where water is escaping, without jackhammering your tiles. In most cases, we can reseal and re-waterproof your shower from the surface, saving you thousands in unnecessary demolition.
