Caroma Basins Buying Guide


Choosing a basin style comes down largely to how the vanity is configured and how the room is actually used day to day, since each installation type suits a different combination of space, storage and daily practicality.

Inset basins

Inset basins remain among the most popular styles in Australia, sitting partly above the bench and partly below it, giving genuine cabinet space underneath without consuming excessive bench space above. This balance suits almost any bathroom well.

Undermount basins

Undermount basins pair particularly well with a stone vanity benchtop, letting the stone itself become the room's visual feature. Since the basin sits beneath the surface, bench space is genuinely maximised, a strong choice for a family bathroom or any space where surface area is at a premium.

Wall-hung or wall-mounted basins

Wall-hung basins mount directly to the wall without needing a full vanity unit beneath them. These suit a powder room or a genuinely small space well, or any bathroom with ample storage elsewhere wanting a minimalist basin as the focal point.

Above-counter basins

Above-counter basins sit on top of the vanity, turning the basin itself into a genuine showpiece while maximising available space in the cabinet below. These suit almost any bathroom style, available across a wide range of shapes and designs.

Semi-recessed basins

Semi-recessed basins overhang the front edge of the vanity, genuinely useful for children or anyone finding a deeper-set basin harder to access. They also suit a narrow bathroom well, where a slimmer vanity unit still needs to maximise usable basin space.

Countertop basins

Countertop basins follow a traditional inset style, sitting within the benchtop with a small lip visible above the surface, well suited to a more traditional bathroom aesthetic.

Freestanding basins

A freestanding basin brings a genuine sense of luxury to a bathroom, standing independently as a considered centrepiece rather than sitting within a vanity. This style suits a modern bathroom wanting a bolder, more architectural statement.

Completing the bathroom

A Caroma basin is easiest to choose once the vanity and tapware direction are settled, since basin installation type and tap compatibility, both depend on those earlier decisions. The Blue Space's Bathroom Vanities and Basin Taps collections are worth reviewing alongside a Caroma basin selection to bring the full room together.

Frequently Asked Questions

What is an above counter basin?

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.

What is an inset basin?

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.

What is a wall hung basin?

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.

What is an undercounter basin?

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.

What is a freestanding basin?

A freestanding basin is a basin unit mounted on a pedestal, column, or exposed stand that supports it from below, with no wall cabinet or vanity behind it. The plumbing may be exposed (as a design feature) or partially concealed within the pedestal. Freestanding basins are a statement piece, often used in powder rooms or feature bathrooms where design impact takes priority.

What is a semi-recessed 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.

What size basin waste do I need?

Most Australian basins require a 32mm or 40mm diameter basin waste. The basin manufacturer's specifications will confirm the correct size. Ensure the thread size (typically 1¼" or 1½") matches your trap and waste pipe connection. Always check the waste specifications of your basin before ordering.

How do I know which basin mixer is right for my basin type?

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.
