Bathroom Installs by GML Construction in North London

Bathrooms on older plumbing systems

Period properties across Hampstead and Highgate often have plumbing runs and water pressure that weren't designed around modern power showers or multiple bathrooms. We check the existing system's capacity before finalising a design, rather than fit a bathroom that never works properly once it's tiled in.

Proper tanking is non-negotiable on every bathroom we fit — it's the difference between a bathroom that lasts fifteen years and one with damp problems in the flat below within two.

What's included

  • Full bathroom strip-out and refit
  • Wet-room and en-suite installation
  • Tanking and waterproofing to current standards
  • Tiling, fittings and heated flooring where wanted
  • Plumbing upgrades where existing pressure or pipework is inadequate

En-suites as part of loft or extension projects

A large portion of our bathroom work is en-suites added as part of a loft conversion or extension, which usually means routing new plumbing through spaces that weren't originally designed for it. We plan this at the structural design stage, not as an afterthought once the room's built.

Common questions

Can I get a power shower with older plumbing?

Often yes, but it may need a pump or pressure upgrade first — we'll assess your existing system's capacity before finalising the design so the shower actually performs as expected.

How long does a bathroom installation take?

A standard bathroom refit typically takes 1–2 weeks from strip-out to completion, longer if structural or major plumbing changes are involved.

Do you fit en-suites as part of loft conversions?

Yes — this is one of our most common requests, and we design the plumbing routing into the loft conversion plan from the start rather than retrofit it afterward.
