Will be refurbishing our shower at home shortly. SWMBO has decided that
it might be nice to fit it out with flat perspex-type panels rather than
conventional tiles, like you often get in hotel rooms etc.

I have no experience of fitting anything like this, and googling has
thrown up number of possible suppliers (none of which I've ever heard of, eg
http://www.bathroommarquee.co.uk/decos-spaceline.php
http://mermaidpanels.com/ )

Costs appear to vary from about the same as tiling to substantially
more. Anyone done this as a viable alternative to tiling? Any tips,
experiences, sources of materials etc gratefully received.
