tile in mobile home?
 

have to replace the floor in both barhrooms of my mobile home. is it even a good idea to go with tile? and if so would the size of the tile make a difference?

Tile is usually something that must be added during the making of the vehicle.
Otherwise it is a custom job big time.
Mostly because of the movement of the substrate.

This is not firsthand experience. I believe I have heard discussions on the matter.
