Vessel sinks used to be exclusive designer picks back before the style caught fire in the late 2000's. These attention-grabbing lavs are still hugely popular and can be a great option for any homeowner seeking to add some eye candy to their bathroom.
By definition, a vessel sink is a basin that sits on top of a vanity countertop, as compared to the traditional "drop-in" under mount sink. Glass and ceramic are the most common materials used to make vessel sinks, but there are plenty of exotic finishes such as natural stone, stainless steel, copper, marble, and even wood.
If you've done any research, you've probably heard mixed reviews about vessel sinks. Here are some facts to help you decide if this style is right for you:
Style
Probably the biggest plus of a vessel sink is its "wow factor". Vessel sinks in the bathroom is a fairly recent trend; it's not something you see in every bathroom. A well-chosen design dresses your bathroom like a good piece of jewelry.
Installation
Vessel sinks are much easier to install than traditional under-mounted sinks. All you have to do is cut a small hole (about 1 5/8") in your countertop. You can do this yourself and hold on to the extra money you would have otherwise spent paying a contractor.
Flexibility
Because they are easy to install, you can swap out your vessel sink when you want to update your bathroom with a new look.
Increased Counter Space
Although it's not much, you do gain a bit more space beneath the ridge of the sink where an under mount sink would typically sit. This is great when you have a small vanity.
Aesthetics
Vessel sinks can make the room feel bigger and here's why: Typically, you'll choose a vanity that's a few inches shorter to accommodate the extra height of the vessel. This increases the space between the countertop and the ceiling, giving the illusion that your ceiling is taller.
Plumbing
Because your vessel sink is "on display", you'll probably be extra careful about keeping it pristine, and that means cleaning up hair and other debris before it can clog your drain.
