This was an interesting project, an old 1920's property with an external coal bunker. The client is an elderly lady and said it would be great if she didn't have to use the stairs, could I perform a miracle and turn the black coal house into a white shower room.
I like a challenge!
Need I say they were blown away and very happy with the final outcome, a bit of luck allowed for a good route to run the waste, picked up the mains water in an external toilet and electrics back to consumer unit.
Walls were tanked and then covered in cement boards prior to applying tiles.
