I've tried to explain to him but he won't have it. It is way too big for the room otherwise I would of re laid it myself. They know they have got it wrong but are not prepared to change it for correct size it seems
I think what they've done is measured out the room but not taken in account that there's a shower tray in there now!
As I said they are really particular about quality up to now anyway!
I measured up a bathroom at the start of the year & got too big a heat mat,
I started fitting it then realised it was far too large so rolled it back up went to CTD & bought a smaller one.
It's still lying in my garage, I will need to get it advertised..
