Laundry Tub Sizes and Capacities

Laundry tubs are rated by the volume they hold, and matching that capacity to how your household actually washes is the key to a laundry that works. A drop-in tub set into a bench gives a neat, built-in finish while offering the depth you need for soaking and hand-washing. This guide helps you pick the right size.

Reading tub capacity

Tub capacity is usually given in litres, and it reflects how much water the bowl holds to the overflow. A larger capacity suits households that soak bedding, sports kit or work clothes, while a compact tub is fine for lighter, occasional use. Depth matters as much as the headline figure — a deeper bowl fills a bucket without splashing and holds bulky items under the water more easily.

Matching size to your household

A busy family that hand-washes and pre-soaks regularly will get more from a generous tub, whereas a smaller household or apartment may prefer to save bench space with a compact one. Think about the biggest single item you’ll wash by hand and choose a bowl that swallows it comfortably. Leaving bench space beside the tub for sorting and folding is worth planning in too.

Fitting a drop-in tub

A drop-in tub sits in a cut-out with its rim resting on the benchtop, giving a tidy, built-in look with storage possible below. Cut the opening to the supplied template and seal the rim to keep water out of the cabinetry. Confirm the waste and trap line up with the existing plumbing, and pick a mixer with enough spout height to fill a bucket under the tap.
