Do modern bathroom sinks (china) not use any mechanical fastenings to hold them to the countertop? I have one that wiggles in the cutout and there is nothing underneath to tighten. There is a bead of caulk under the lip of the sink, but it isn't stuck to the countertop.
Any suggestions, or am I going to have to unhook the pipes and "reglue" it?
Thanks, Red
