About the end of December there was a home program shown on Style and they showed a bathroom that had a shower with a tray in the shape of a snail (unfortunately that is the only way that I can think of explaining it!) Is there anyone that can advise me on where I could possibly get one?

Probably the best thing to do would be to search on the net for the programme you watched (eg realrooms, changingrooms with the name of the channel that they originally appeared on). Most of these programmes have a details page for each of the makeovers showing stockists etc. Good luck.
