This basin does not have an overflow.
A sit-on basin is very much what the name implies - a basin that sits on top of a counter. These basins do not have tap holes and therefore Victorian Bathrooms recommends the use of a wall mounted basin mixer configuration or a deck mounted basin mixer specifically designed to accommodate sit-on basins.
This basin does not have tap holes.
Please note that this basin does not have an overflow.
As this basin does not have an overflow, it will require an unslotted basin waste (to be purchased separately).
Made of ceramic.
