When you are installing a vessel sink, one thing to consider is the vessel sink drain. Whether you should purchase or have already purchased a vessel sink drain, it is much better if you know the advantages and the disadvantages of having a vessel sink drain with or without overflow.
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 be rest assured that 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. Another thing is the price. It costs twice as much as a vessel sink drain without overflow feature, is not widely available and is a bit difficult to install by yourself.
Vessel Sink without Overflow
The good thing about this is that it is very easy to install. You can actually install it in 10 minutes and it is cheaper than the one with overflow feature.
The disadvantage about this is that if you left the faucet open, the water will spill over the counter and wet all things that come in contact with it, leaving you with tons to clean up. Another thing is that water does not flow smoothly.
