The lavish designer look of undermount bathroom sink is a must have for any bathroom upgrade. Undermount bathroom sink is a newer concept but have become increasingly popular. The undermount bathroom sink is a style of sink that is covered from below. It means the bowl of the sink (whatever shape it is) is plastered or enveloped with some material. Now, starting with the basics of a sink – it is a bowl shaped fixture which is used to wash hands. When this sink is mounted in the bathroom and only it’s upper view is visible (because the rest of the part is enveloped), this fixture is called as the undermount bathroom sink. The advantage is that it gives a contemporary look to the whole space .
