Counter top basins can sit on a floating shelf or most furniture units with a full worktop. These basins are available in more unique and modern designs than those offered by other types of basins. Some countertop basins are made with a tap hole so that they can be used in conjunction with a standard basin mixer tap. On the other hand some do not incorporate a tap hold in the design and instead should be used with high rise basin mixers. Counter top basin installation give a smart and seamless finish because the plumbing is hidden by the shelf of unit that the basin is mounted on.
