How big is a portable dishwasher?#
A portable dishwasher is 24 inches wide (18 for the compact) and 35 to 36 inches tall, rolling on casters so it needs no cabinet. The table below covers the full-size, compact, and butcher-block-top versions, and the clearances give the footprint and door swing a freestanding unit takes.
Portable dishwasher dimensions by configuration#
| Configuration | Width (in) | Height (in) | Depth (in) | Best for |
|---|---|---|---|---|
| Full-size portable (24-inch) | 24 | 35–36 | 26–28 | a rental with no cabinet to spare |
| Compact portable (18-inch) | 18 | 36 | 26 | a small kitchen that rolls it to the sink |
| Portable with butcher-block top | 24 | 36 | 27–28 | extra counter space between washes |

Installation clearances for a portable dishwasher#
- Rolling footprint: 24 in in of floor width a full-size portable dishwasher parks in when it is not rolled to the sink.
- Caster clearance: 2 in in the casters add under a portable dishwasher, which is why its work top sits near counter height.
- Faucet coupler: A portable dishwasher hooks to the kitchen faucet with a quick coupler, so it needs no plumbed supply line.
- Door swing: 24 in in of front space a portable dishwasher door needs to drop open at the sink.
Will your portable dishwasher fit? Clearances and door swing#
A portable dishwasher is judged by its parked footprint, not a cabinet opening. A full-size unit occupies about 24 inches of floor width when it is not rolled to the sink, and stands 35 to 36 inches tall — roughly counter height — because the casters add about 2 inches underneath. That caster height is why the work top sits where it does. It needs no plumbed supply line: a portable hooks to the kitchen faucet with a quick coupler, so the only requirement is a faucet it can reach and a nearby outlet. In front, the door needs 24 inches to drop open at the sink. Measure the parking spot for the 24-inch footprint, confirm the faucet reach, and leave the door room, and a portable works in a kitchen with no cabinetry to spare.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

Portable dishwasher sizes by type: full-size portable (24-inch), compact portable (18-inch), portable with butcher-block top#
The full-size portable at 24 inches wide is the rental and no-cabinet answer, holding a standard place setting count and rolling to the sink for each wash. The compact portable at 18 inches wide and 36 inches tall is the small-kitchen version, taking less floor space while still rolling to the faucet — the pick when even 24 inches of parking is tight. The portable with a butcher-block top adds a usable work surface on top, 27 to 28 inches deep, so it doubles as extra counter space between washes in a kitchen short on prep room. All three connect at the faucet with a coupler rather than a plumbed line, so the choice is footprint and whether you want the butcher-block work surface on top.
