Kitchen islands: sizing, seating and services

An island is decided by the floor around it, not by the bench itself. Before anything is drawn we measure what is left once the island is in: the walkway each side, the swing of a dishwasher door, the room a second person needs to pass behind a cook.

900 · 1000 · 1200 WALKWAY

Start with the floor you have left

The first drawing of any island is a plan of empty floor. We set the island out, then check every path around it with the drawers, the oven and the dishwasher shown open. A room that measures well on paper and fails with a door open is a room that will annoy someone every evening.

1200 mm Comfortable on the working side: two people pass, drawers and the dishwasher open fully.1000 mm A workable single-cook walkway, tight but usable on the non-working side.Under 900 mm The island is squeezing the room. A peninsula or a longer bench run gives more bench for less floor.Corners Watch the diagonal pinch where a walkway meets a doorway or fridge swing — that is where plans usually fail.

If the numbers say no, that is useful early. Small kitchen renovations covers what replaces an island in a narrow unit or villa plan.

750 · 900 · 1050 SEAT HEIGHTS

Three ways people sit at an island

Seating height decides stool choice, overhang and how much bench you lose.

750 TABLE HEIGHT

Table-height return

A lower leg off the island, sat at with dining chairs. Best where the island doubles as the only eating surface.

900 BENCH · 300 OVERHANG

Bench-height seating

The common choice: one continuous 900 mm surface with a 300 mm overhang for knees and roughly 600 mm of width allowed per stool. Cabinetry behind the overhang is shortened, so storage is planned around it rather than lost to it.

1050 RAISED BAR · 2 LEVELS

Raised bar, or none at all

A raised upstand hides the working bench from the dining side and keeps mess out of sight, at the cost of a stepped profile that reads heavier in a small room. The third option is honest and often right: no seating, full-depth drawers both sides, and an island that is purely preparation and storage.

Seating height decides the benchtop edge and overhang support — see kitchen benchtops.

WASTE · WATER · POWER · EXTRACTION

What you put inside the island

Every service that lands in an island has to travel under the floor or through the slab, so it is confirmed at the measure and design stages — not once the carcasses are in.

Sink and dishwasher — waste and supply have to reach the island. On a timber floor that is straightforward; on a concrete slab it means trenching, which changes both the program and the cost of the job.Cooktop — needs extraction above or a downdraft unit below, plus clearance to any seating. Splashback protection and the pendant positions both change once a cooktop moves into the island.Power — outlets sit in the end panel, under the overhang or in a flush pop-up. The position is a drawing decision, because a waterfall end leaves nowhere to add one later.Bins and drawers — the bin drawer belongs beside the sink, which then dictates which side the deep pot drawers fall on. Islands without services are simply banks of drawers, and they hold more.

All of it is coordinated at stages two to four of the thirteen-stage process, alongside custom kitchen design.

FOUR QUESTIONS ASKED AT THE MEASURE

How small can an island be?

Once you drop below roughly 1200 mm long and 900 mm deep it stops earning its floor: too shallow for drawers both sides, too short for two stools. A narrower bench against a wall usually does more work.

Is a waterfall end worth it?

It suits stone with strong veining, where the pattern can be mitred to run down the end. On a quiet surface the same money often does more in extra drawer hardware or a better splashback.

Can an island be added to an existing kitchen?

Often, if no services are required and the clearances hold. Matching an existing benchtop and door finish is the harder part, and is worth checking before the idea is costed.

How many pendants above it?

Set the ceiling points from the island centreline, not the room centreline — the two are rarely the same. Positions are marked during the electrical stage, after the cabinetry is in and the true centre is known.

Send the room and we will tell you whether an island fits

Rough measurements and a photo of the space are enough to start. If the clearances do not work, you will hear that first, with the alternative that gives you more bench for the same floor.
