A 500mm base cabinet is the narrowest width most UK kitchen sinks are designed around, and not every sink in a given range fits it. RUMO confirms five models for a 500mm cabinet: one undermount and four inset, spanning both silver and anthracite finishes. This page lists exactly which ones, since guessing from a sink's headline size alone isn't reliable at this width.
Which RUMO sinks fit a 500mm base cabinet?
Five RUMO sinks are confirmed for a 500mm base cabinet: the 5045 undermount single bowl, 8050A inset single bowl with drainer in Black Anthracite, Aurora inset single bowl with drainer, Artic inset single bowl with drainer, and 10050A inset single bowl. That's one undermount option and four inset options, giving a choice of mounting style even at the tightest cabinet width in the range.
| Model | Mounting | Finish | Footprint |
|---|---|---|---|
| RUMO 5045 | Undermount | Silver | 500 x 450 x 200mm |
| RUMO 8050A | Inset, with drainer | Black Anthracite | 800 x 500 x 200mm |
| RUMO Aurora | Inset, with drainer | Silver | 910 x 450mm |
| RUMO Artic | Inset, with drainer | Silver | 800 x 500mm |
| RUMO 10050A | Inset | Silver | 1000 x 500mm |
Why don't all single bowl sinks fit a 500mm cabinet?
Single bowl doesn't automatically mean 500mm-compatible, because base cabinet minimum depends on the bowl's own width and depth, not the bowl count. RUMO's Elite Silver, for example, is single bowl but needs a 550mm cabinet or wider, since its bowl is one of the deepest and widest in the range at 465 x 415mm. A sink's minimum base cabinet requirement is a separate, confirmed figure, not something to estimate from the bowl configuration alone.
Does mounting style change what fits a 500mm cabinet?
Both mounting styles fit a 500mm cabinet, but the undermount vs inset choice still matters at this width, since undermount needs a solid worktop machined to the sink's exact footprint while inset works with any worktop material. The 5045 is RUMO's only 500mm-compatible undermount sink, so a 500mm cabinet with a laminate worktop rules out undermount entirely at this size and points toward one of the four inset options instead.
What should you check before buying for a tight cabinet?
Confirm the cabinet's internal width, not the door or carcass measurement, before matching it against any sink's stated minimum. RUMO's sizing guide covers how to take that internal measurement and what clearance margin to allow either side of the sink footprint, which matters more at 500mm than at any wider cabinet size in the range.
