Double Bowl Sinks

Start with the internal width of your sink cabinet, not just the available benchtop space. A double bowl sink usually needs more cabinet room than a single bowl because both bowls, wastes, plumbing and mounting hardware need to fit underneath. Check the overall sink size as well as the width and depth of each individual bowl. If you regularly wash large pots or trays, make sure at least one bowl is large enough for them. Browse our Double Bowl Sinks or wider Sink collection.

Choose a double bowl if you regularly want to wash, rinse, soak or prepare food at the same time. One bowl can hold dishes while the second remains available for rinsing vegetables or filling containers. A single bowl may be better if you mainly wash large cookware and want one uninterrupted washing area. Double bowls also generally require more cabinet and benchtop space. The better choice depends on your daily routine rather than household size alone. Compare Double Bowl Sinks with Single Bowl Sinks.

Equal-size bowls provide two similar working areas and can be useful if both sides are used regularly for washing and rinsing. Unequal bowls give you one larger main bowl and a smaller secondary bowl, which can be more practical if you want space for bigger pots while still keeping a separate area for rinsing or food preparation. Check the actual internal bowl dimensions rather than relying only on the overall sink size. The best configuration depends on how you use the sink and how much cabinet space is available.

A topmount sink sits over the benchtop cut-out and can suit many straightforward installations or replacement projects. An undermount sink is installed beneath the benchtop and creates a cleaner transition from the bench into the bowls. It can also make it easier to wipe crumbs and water directly into the sink. The suitable installation method depends on the sink design and benchtop material, so always check the individual product specifications. If undermount installation is a priority, compare our Undermount Sinks.

A built-in drainer is useful if you regularly hand-wash dishes, rinse produce or need a dedicated area for wet cookware. It gives water somewhere to drain without using a separate drying rack, but it also increases the overall sink footprint and uses more benchtop space. A double bowl without a drainer may suit kitchens where a dishwasher handles most cleaning or where preserving bench space is more important. If a drainer is part of your daily routine, compare our Sinks with Drainer.

Choose a mixer with enough spout reach to comfortably serve both bowls. A swivel spout is particularly useful because it can move from one side to the other, while a pull-out or pull-down mixer can make rinsing larger bowls and cookware easier. Also check whether the sink includes a tap landing or whether the mixer needs to be installed through the benchtop. The tap position should allow water to reach both bowls without excessive splash. Plan the sink and mixer together before the benchtop is cut or plumbing is finalised.

Before ordering, confirm the overall sink dimensions, individual bowl sizes and depths, minimum cabinet width, mounting method, benchtop material, waste positions, tap-hole arrangement and whether you need a drainer. If replacing an existing sink, do not assume a similar overall size will fit the current cut-out. Compare the manufacturer cut-out requirements carefully. Also check the space underneath for two wastes, plumbing, bins or drawers. Browse the Double Bowl Sinks and wider Sink range before finalising your order.
