We have laminate in our bathroom. It was there when we moved in 4 years ago.
We have 2 DS (5& 8) and , between them they have destroyed it.
Behind the loo it has warped and blistered due to the constant missing of the target 
It is making the whole house stink and nothing will get rid of the stench. We need to rip it up and replace it.
What is the best covering, which will not be damaged by a constant stream of piss and will not retain the stench.
Help.
