Bathrooms concentrate a lot of plumbing into a small space — water supply, hot water, wastes and drainage. Getting it right during a renovation avoids leaks behind new tiles.
A4plumbing works with homeowners and other trades on bathroom renovations, from rough-in before walls are closed to fit-off once tiling is finished. We also repair existing showers, vanities, baths and toilets.

Common problems we help with
- Renovation rough-in and fit-off
- Relocating showers, toilets or vanities
- Leaking shower mixers and wastes
- Slow-draining showers and basins
- Upgrading tapware and fixtures

Do you do full bathroom renovations?
We handle the plumbing component. Tiling, waterproofing and carpentry are done by other licensed trades — we're happy to work alongside them.
