I'm looking for a small remnant countertop piece that's 24" by 16". It's for a very small bathroom I'm remodeling myself. I've looked online but can't seem to find anyone who sells small remnant pieces of granite, marble, quartz or soapstone but doesn't want to do the fabrication themselves. It's a very simple project (a countertop with a vessel sink) that I can handle myself.

It's very weird that I can't just buy a small slice of rock. Any suggestions?
