A bathroom renovation in Marylebone, W1 ran across this week, starting with copper pipe first-fix and plastering preparation and finishing with bath tap installation β€” a straightforward job made to look easy by getting the sequencing right from the start.

Copper pipe first-fix before plastering

Copper pipe runs for the bath and basin were positioned and prepared before any plastering went ahead. Once a wall is plastered, moving a pipe run means breaking back into finished work β€” so getting the layout correct at this stage, before anything is covered, is what avoids costly rework later in the job.

Finishing with first-fix plumbing and bath taps

With the copper pipework prepared, first-fix plumbing and bath tap connections followed. On renovation jobs like this, Ralf coordinates the plumbing first-fix with tiling and electrical trades so the whole sequence runs correctly β€” pipework and cabling go in before plastering, fittings connect once tiling is finished, and nothing has to come back out once it's in.
