Arlene - Fiona and I spoke to Steve Goodwin (Ikea Steve - or endpeg as he's known on this forum) briefly about this last time we were out - we were a wee bit concerned about the grouting upstairs and feared leakage - certainly aound the edges. We haven't followed it up though, as yet. (I've got the job of cleaning the tiles when I go back out in the Summer but with the golf course beckoning, it could be a long wait!)
Might be worth asking Steve for advice and a quote - let me know how you get on. (If you need his details, I'll get them to you.)

PS - only 1 year to go til we retire and get back to Stonehaven - can't wait.
