I've removed a couple of tiles from my bathroom wall (for a remodel), and I'm unsure about what each of the layers are underneath, how to proceed, and how to make sure I'm not damaging anything structural.

I was expecting plasterboard and then bricks, but am not sure exactly what I'm looking at.

Below are photos, of the top corner.

  • Are we looking at a top corner? Can you include a soda can or something for scale, please. Jan 3, 2016 at 19:17
  • @ZachMierzejewski Yes, top corner, and added a photo with a can Jan 3, 2016 at 19:29
  • That is plaster wall, old school.. How old is the house, built before 1950? You should find strips of wood under it all. I see the hair in it for strenghtening, and the gray top coat for the smooth finish. It is usually white though...

  • Then again it could be applied right over brick. How the answer goes will make a difference, but if you remove anymore, you will need to secure a cement board over the wall most likely to replace the dimension that is taken away by removing the plaster.

  • @jack Yes, pre 1950. Somewhere around 1900 (although converted to flats more recently). Jan 4, 2016 at 5:50

1 Answer 1


Looks like drywall over old plaster (horse hair plaster) that was applied to a brown coat which has horse hair in it. This might be real good because that brown coat could be over an inch deep & will take screws beautifully for a cement board covering & easy remodel.
