You may be correct about the frozen pipe. I would suggest that the OP check
for pipe cracks and make sure they know where the shut off valve is before
thawing it out.

frozen? open the vanity below the sink and let the pipes running thru
an outside wall thaw. speed it up by warming things up with a fan. hot
water freezes before cold water.
