Glass tiles

[Wolfiefan]

We are about to redo bathrooms. Our plumber suggested seeing if we could get a single glass tile made to size to make a tidier splashback.
Has anyone done this? Is there a particular company you'd recommend?
Or other ideas welcomed.
TIA

Looking again I can see glass splashbacks but they seem to be mainly for kitchens.

A glass merchants should be able to help with this. I've just had some toughened glass shelves made for our bathroom. Picked them up from their low key showroom - amazing what they can do.
