We've come to the point of wanting to replace our dated bathrooms. The whole house was last done in 1984 and we moved in last year.
Before I start pulling down the ceiling tiles I wonder if anyone might able to suggest if they contain asbestos or not? I've added a few images to try and help. They're particularly thick, I'd say 10-12mm and they resemble pumice stone, though perhaps rougher. They do depress slightly when pressed and they're quite crumbly.
Any thoughts anyone?
