I am considering laying tiles under a toilet pan to help sondproofing, the floor beneath is only single skin. Would the tiles crack? Any other suggestions to soundproof ?
:)

What is "toilet pan" ?

I have heard of a shower pan but there is no toilet pan in my experience. Can you better tell us your situation? Ceramic tile needs at least a 3/4" plywood sub floor and 1/4" Hardibacker board or Wonderboard before you can tile.

Apologies I am in UK , must be language difference! I am actually referring to the toilet. I wanted to place it on the tiles to give an added layer underneath to improve soundproofing in the room below when the toilet is used. The room below has beams so there is very little gap to soundproof.

As I mentioned, you need more than your current subfloor for tiles, they will crack or at least the grout will crack. Also, the sound proofing will be very minimal. Filling the cavity between the floor of this room and the space below will give good soundproofing. Tile is rigid,brittle and can transmit sound rather than absorb it.

Oh, sure, language barrier... In America we refer to it as Toilet Bowl and Toilet Tank. Thanks for clarifying ! :-D
