A single bowl sink gives you one large basin and the most usable space for oversized pans. A 1.5 bowl sink pairs a full-size main bowl with a smaller second bowl for draining or prep. A double bowl sink gives two full-size basins side by side for washing and rinsing at the same time. The right one depends on cabinet width and how you actually use the sink, not just kitchen size.

What is a single bowl kitchen sink?

A single bowl kitchen sink is one continuous basin with no divider, and it's the format RUMO builds most of its range around: 15 of the 20 sinks in the catalogue are single bowl. A single bowl gives the most uninterrupted floor space inside the sink, which matters most for oversized roasting trays and stockpots that would straddle a divider in a split-bowl design. RUMO's single bowl inset sinks run from 800mm to 1000mm wide, with bowl depths between 200mm and 220mm depending on the model.

What is a 1.5 bowl kitchen sink?

A 1.5 bowl kitchen sink combines one full-size bowl with a second, smaller half bowl, usually around 300 x 160mm, used for draining, prepping vegetables or resting a colander while the main bowl stays free. RUMO builds four 1.5 bowl sinks: the 6046 and 6744 in the undermount range, and Prime Silver and Prime Black Charcoal in the inset range. The half bowl works well as a dedicated prep or waste-disposal side, since it keeps food scraps separate from whatever's soaking in the main bowl.

What is a double bowl kitchen sink?

A double bowl kitchen sink has two full-size basins of equal or near-equal size, set side by side, so you can wash in one and rinse or stack in the other without moving anything between stages. RUMO's 8044 is the range's one double bowl model, an 800 x 440mm undermount sink built from 1.0mm SS304 steel. Two full bowls take up more worktop run than a single or 1.5 bowl layout, so double bowl suits wider cabinets rather than tight galley kitchens.

Which bowl configuration suits a small kitchen?

Single bowl suits a small kitchen best, because it needs the least cabinet width and gives the most usable basin space per millimetre of worktop. RUMO's narrowest single bowl option, the 5045 undermount, needs a base cabinet from 500mm, the tightest fit in the range. A 1.5 bowl works in a small kitchen too if the half bowl earns its keep for prep or drainage, but a double bowl generally needs 800mm-900mm of cabinet run and doesn't fit well below that.

Which bowl configuration suits a busy family kitchen?

A double bowl or 1.5 bowl suits a busy family kitchen better than a single bowl, because separating wash and rinse, or wash and prep, speeds up the routine when two or more people are cooking or clearing up at once. The trade-off is cabinet space: both formats need more worktop run than a single bowl, so they fit best in kitchens with 800mm or more available for the sink alone.

Bowl configuration and mounting style get decided together in practice. If you haven't settled on undermount vs inset yet, that choice affects which bowl widths are available, and RUMO's sizing guide walks through matching a bowl configuration to your actual cabinet measurement rather than a rule of thumb.
