Cloakroom & Downstairs WC Plumbing
Cloakroom & Downstairs WC Plumbing
A downstairs cloakroom adds real value to a family home — the plumbing challenge is fitting the waste run and feeds into a tight, often under-stairs space.
Cloakroom & Downstairs WC Plumbing in North London, done properly the first time
We plan and install the full plumbing for a new cloakroom: hot and cold feeds, soil or macerator waste, the WC, compact basin and often an extractor connection, with everything boxed in neatly to keep the small space usable.
For existing cloakrooms we replace tired suites, fix running cisterns and cure the smells that come from dried-out or badly fitted traps. Popular across Barnet's 1930s semis where the under-stairs space was never originally plumbed.

Your questions, answered
Can a WC be added under the stairs?
Usually yes. The deciding factor is the waste run — gravity if we can reach a soil stack, macerator if not. We survey and confirm.
Do I need building regulations approval?
New WCs must meet ventilation and drainage requirements. We install to those standards and can advise on any notification needed.
How long does a new cloakroom take?
Plumbing is typically two to three days depending on the waste run; tiling and decoration follow after.
Why does my cloakroom smell?
Almost always a trap that has dried out or a poor waste seal — an easy fix once we see it.
