On the rocks, please

I really like the looks of a glass countertop, & glass is reusable/recyclable.  It’s also non-porous, which means stain and bacteria resistent.

I like the thicker dimensions because it seems less fragile that way. Definitely the full 1.5″ or better, like this one from ThinkGlass:

And this is an excellent example of combining cold materials (glass, stainless steel) with warm ones (wood):

Glass countertops can be backpainted and/or lit from below for even more versatility, like this one from CBD Glass Studios:

Glass can also be a backsplash, like these from Dreamwalls Color Glass:
