And no, before anyone says it, it isn't wee! The loo isn't leaking cos I've had a good old feel around the back of it. The biggest damp patch is at the right side of the loo coming from the skirting board, with smaller patches tracking along the joints between floorboards at the front near the toilet. Neither patch seems to come directly from the toilet. Not a good description I know but can anyone help. Could condensation do this - it's a separate loo with no heating. Ta.
