Shower and Bathroom Plumbing Problems: Leaks, Pressure and Drainage

Bathrooms combine water supply, drainage, fixtures, waterproofed areas and high daily use, so several different problems can produce similar symptoms. A wet floor, weak shower or slow drain does not always have the same cause.

For more detail on the service itself, see our bathroom plumbing page.

Leaking shower fittings

Drips from shower heads or mixers may involve worn cartridges, seals or tapware components. Visible leaks at fittings are different from water escaping behind the wall.

Low or inconsistent pressure

Pressure problems can be isolated to one fixture or affect the wider property. Blocked shower heads, mixer faults and system pressure issues should be considered separately.

Slow shower drainage

Hair, soap and other debris can restrict shower wastes. If several drains are slow, the problem may be further down the drainage system.

Water outside the shower area

Water on the bathroom floor can come from plumbing fittings, screens, seals, wastes or waterproofing-related issues. The source needs to be identified before repairs are chosen.

Vanity and basin leaks

Slow leaks under vanities can damage cabinetry before they are noticed. Check wastes, tap connections and valves if moisture appears inside the cabinet.

Recurring problems need diagnosis

If a bathroom issue returns after a simple repair, it is worth checking the broader plumbing rather than continuing to replace individual components.
