Totally gutted a bathroom. Once basin, toilet, shower mixer, radiator, bath out, floor tiles up, skirting and coving off, started hacking off wall tiles and the walls are *****! Cracked paint on stud walls and browning that you can remove from the brickwork with your fingers. Got one wall back to brick and 1/2 wall back to stud. Decided to commit and going to totally remove another 2 1/2 walls tomorrow and dryline Wednesday. Going to put me 2 days behind after day 1 but all the extra effort will be worth it.
