Vessel Sink with Overflow

Start by considering a vessel sink with overflow.


The function of an overflow is that it prevents spillage of water from the basin. It allows the fluid to flow smoothly.

If the faucet is left open and the water continuously flows into the vessel sink, you can rest assured your vessel sink will not be filled with water and spill over your counter.

When the water reaches the overflow drain, it starts draining the water out. It is like a back up drain.


If you are the type of person who walks away from an open faucet, then water will continuously flow without you noticing it because the vessel will not be filled with water if you have an overflow drain.

Price is also a factor. The overflow feature costs twice as much as a vessel sink drain without overflow feature.

This design is more difficult to find and is a bit difficult to install by yourself.

Is skipping the overflow feature right for you?


The good thing about going without the overflow is the vessel sink is very easy to install.

You can actually install it in 10 minutes and it is cheaper than the one with an overflow feature.


The disadvantage about this is if you leave the faucet open, the water will spill over the counter, leaving you with tons to clean up.

The water also flows less smoothly with this design.
