We've had occasional clients asking for 48"/twin basin vanities. We get
the same answer consistently . . . . "Too risky! Used to make them,
but basin diameter was too small and the section between the basins
ends up cracking either while being installed or over time." Even with
a basin as small as one for a wet bar, the amount of supporting
material is so little that I can see how easy it is to crack the
counter.
