Sink and Vanity Installation in Miami, FL
A new vanity, a vessel sink or a second basin. Call to reach an independent plumber who installs bathroom sinks and vanities.
The short answer
Installing a vanity is part carpentry and part plumbing. The cabinet is set level and secured, the top and sink are mounted, and the plumber connects the faucet, a new drain and trap and new supply lines. If the new sink's drain sits at a different height or position, the drain arm or supply valves in the wall may need to move.
The most common surprise is height. A vessel sink sitting on the counter has a higher drain than an undermount sink, and the existing drain arm in the wall may be too low or too high for a clean trap. A plumber can raise or lower the drain arm, which may mean opening drywall behind the vanity.
Old vanities in Miami bathrooms often hide water damage at the cabinet floor from slow drips. That is a good moment to replace the shut-off valves and supply lines and to check the wall behind for soft drywall. If you only need a new faucet on the same sink, see swapping just the faucet.
