We have just completed a bathroom refurbishment. The original bath had been removed, leaving pipework running
above the floor and down the walls. When the old tiling was removed we saw the state of the plasterboard. We replaced the
old plaster board with cement based tile backer board before re-tiling the walls.
We diverted some of the pipework through the loft. That's Michael; jointing some 22mm copper pipe (the fire extinguisher
is out of shot)The waste had to be run to the end of the building between the floor joists.
And here is the finished installation. Well almost: the masking tape is still enclosing the sealing strip. Oops!
And below is a better picture of Michael -just for the girls!
