Grey Basins

The key factor is the height and style of your basin. For standard inset or semi-recessed basins, a regular deck-mounted basin mixer with a spout height of around 100–140mm works well. However, if you have an above-counter or vessel basin, where the bowl sits on top of the benchtop, you will need a tall basin mixer with a spout height of 180mm or more, otherwise the spout will sit below the basin rim and water will splash onto the benchtop. Wall-mounted mixers offer another option for above-counter basins, with the height controlled by your rough-in position. Always confirm basin rim height before purchasing your tapware.

The Water Efficiency Labelling and Standards (WELS) scheme is a mandatory Australian government rating system that measures how water-efficient a tapware product is. Ratings run from 1 to 6 stars, the more stars, the less water the tap uses per minute. For basin mixers, a 5 or 6-star WELS rating is considered excellent and translates to meaningful long-term savings on water bills, particularly important in drought-prone Australian states. All tapware sold in Australia must carry a WELS rating, and most reputable brands now offer basin mixers rated 4 stars or higher as standard. Look for the WELS label on the product or packaging before you buy.

An above counter basin (also called an above bench or vessel basin) sits on top of the vanity benchtop rather than being inset into it. The full exterior of the basin is visible, making it a strong design statement. Above counter basins are available in ceramic, stone, concrete, and composite materials in a range of shapes, round, oval, rectangular, and sculpted forms.

An inset basin (also called a top-mount or drop-in basin) drops into a pre-cut hole in the benchtop, with the rim of the basin sitting on top of the benchtop surface. This is one of the most common basin installation types in Australian bathrooms and suits a wide range of vanity styles. Inset basins are practical, secure, and easy to replace without changing the benchtop.

A wall hung basin is fixed directly to the wall with no vanity cabinet below, it is cantilevered off the wall with the waste pipe running up the wall or through the wall behind. Wall hung basins give a bathroom a very open, spacious feel and are popular in powder rooms, compact ensuites, and contemporary minimalist bathrooms.

An undercounter basin (also called undermount basin) is installed below the benchtop surface, with the benchtop material cut to the basin opening and the basin bonded underneath. This creates a seamless, flush benchtop with no rim or lip, water and mess can be wiped directly from the benchtop surface into the basin.

A semi-recessed basin sits partially into the benchtop (or vanity top), with the front portion of the basin protruding beyond the front edge of the cabinet. This allows for a shallower vanity cabinet (often 350 – 400mm deep instead of the standard 450 – 550mm) while still providing a practical basin size. Semi-recessed basins are ideal for narrow bathrooms where depth is at a premium.
