Thinking on changing my undermount sink to glass vessel sink for my bathroom. I have been really fascinated about the design language propagated by the glass vessel sink. As I was going through an article about upgrading bathroom sinks and accessories. I never had experience with such sinks. I would like to have inputs on glass vessel sinks. The major problem I heard about this sort of sinks are they are really water spot magnets. So an everyday cleaning procedure is required or is there some other approach to keep them spot free for week long.
