The Best Countertop & Portable Dishwashers: 4 Compared (and One to Skip)

RBE top pick

GE GPT225SSLSS 24-Inch Portable Dishwasher

See why it wins Find it on Amazon Compare all

The GE portable cleans and dries like a built-in and is the one to buy if you have the floor space and budget. If you want to spend less or need a narrower cart, the 18-inch Danby DDW1805EWP does the core job well.

If your kitchen has no room for a built-in, a countertop or wheel-around portable dishwasher is the honest workaround. But they range from genuinely built-in-good to cramped novelties, and one 18-inch cart gives away more than its spec sheet first suggests. We weighed four current options: two we'd happily recommend, one that only makes sense for the tiniest spaces, and one to walk past.

Danby

Danby DDW1805EWP 18-Inch Portable Dishwasher

Buy it

The value portable: a slimmer 18-inch cart that still holds a real 8-place load for less money.

Best for: Budget-minded renters who still want to wash a full sink of dishes in one go.

$$ · mid-range

Why we like it

• Narrow 18-inch body (17.69 in listed) fits kitchens too tight for a 24-inch unit
• Eight place settings with a silverware basket - more than a tabletop countertop model
• Rated at 52 decibels, ENERGY STAR, and up to 3.5 gallons per wash
• Rolls to the sink on castors and quick-connects to most kitchen faucets

Know before buying

• Only 4 wash cycles (heavy, normal, 90 min and rapid)
• Danby lists no heated drying or sanitize cycle, so plastics may come out damp
• Weighs 116.6 lbs, so rolling it to the sink is a real push

Amazon had no buyable listing for this when we last checked. The link still works if it returns.

Danby

Danby DDW631SDB 6-Place Countertop Dishwasher

It depends

A true counter-top box for the tiniest kitchens - brilliant for one, frustrating for a household.

Best for: Solo dwellers and tiny kitchens where counter space is easier to spare than floor space.

$ · budget

Why we like it

• Small enough to sit on the counter, so it needs no floor space at all
• Digital controls with several cycles, including quick and eco washes
• Connects to a kitchen faucet and is the cheapest route into a real dishwasher
• Well suited to studios, RVs, offices and single-person homes

Know before buying

• Only about six place settings, and tall dinner plates or pots often won't fit
• Eats a big chunk of counter space while it's parked there
• Small loads mean you'll end up running it more often

We'd skip it

SPT

SPT SD-9263SS 18-Inch Portable Dishwasher

Skip it

An 18-inch stainless portable whose own maker page lists residual heat drying only and warns that side-sprayer faucets leak on hookup.

Best for: Kitchens with a plain faucet that already own a dish rack for the damp plastics; most buyers are better served by the Danby.

$$ · mid-range

Why we like it

• 8 place settings, 6 wash programs and a 1 to 24 hour delay start
• Rated at 52 dB, ENERGY STAR, stainless steel interior
• Casters and a quick-connect faucet adapter included

Know before buying

• SPT lists the drying system as residual heat drying, with no heated dry, so damp plastics are the expected result
• SPT warns that faucets with a side sprayer will experience leakage under line pressure and will most likely need a separate water line
• Depth with the door fully open is 46.5 inches, a lot of floor in a small galley kitchen

How we judged the field

We don’t run our own lab. Instead we synthesize a large volume of long-term owner reports, then weigh them against what actually matters in a small kitchen. For countertop and portable dishwashers that means five things: real cleaning power on baked-on food, how much a single load holds, how loud the machine is in a room you’re probably sitting in, how well dishes dry, and how painless the faucet hookup and storage are day to day. We also flag value traps - cases where two machines are mechanically the same but priced far apart.

This is the closest a movable dishwasher gets to a built-in. Owner reports consistently describe strong cleaning on stuck-on food and drying that leaves dishes usable rather than dripping. Capacity is the real story: as a full-size portable it clears a family dinner in one run, something no tabletop unit can touch. It’s also described as quiet for a portable and rolls easily on its casters. The catch is size and price - it’s 24 inches wide, needs a home to park in, and has to be wheeled to the sink and connected for each cycle. If your kitchen can absorb that, it’s the one to buy.

The DDW1805EWP, Danby’s current 18-inch portable in place of the DDW1801MWP, is the sensible value pick. Its 18-inch body slips into kitchens that can’t fit a 24-inch machine, yet it still holds eight place settings - more than any countertop box. Danby rates it at 52 decibels, ENERGY STAR, and up to 3.5 gallons of water per wash, with simple electronic controls and a display light, and like every unit here it rolls to the sink on castors and quick-connects to the faucet. You give up some refinement: there are only four wash cycles, Danby lists no heated drying or sanitize option, so plastics may come out damp, and at 116.6 lbs it is a real push to move. For the money, those are fair trade-offs, and it does the core job - washing a full sink of dishes at once - well.

The DDW631SDB is the only true countertop unit in the group, and whether it’s right for you comes down entirely to your space. If floor room is genuinely zero - a studio, an RV, a small office kitchenette - a machine that sits on the worktop and washes about six place settings is a small miracle, with digital controls and a couple of useful cycles. But that capacity is tight: tall dinner plates and pots frequently won’t fit, small loads mean running it more often, and it monopolizes a stretch of counter while it’s there. For one person it’s great. For a household, the frustration adds up fast, which is why it’s a ‘depends’ rather than a clear buy.

On paper the SD-9263SS matches the Danby: 18 inches wide, eight place settings, 52 dB, ENERGY STAR, a stainless interior, six wash programs and a 1 to 24 hour delay start. The reasons to pass are on SPT’s own page. The drying system is listed as residual heat drying, so there is no heated dry to fall back on and damp plastics are the expected result. SPT also warns that faucets with a side or detached sprayer will experience leakage under line pressure and that you will most likely need a separate water line, which defeats the point of a portable for many renters. And with the door fully open it needs 46.5 inches of depth. If your faucet is plain and you already hand-dry plastics it will work, but the Danby is the simpler buy.

GE GPT225SSLSS vs Danby DDW1805EWP: which should you buy?

These are the two we’d actually recommend, and they split cleanly on space and budget. The GE is the better machine in most respects owners mention - bigger, quieter, and better drying - and if your kitchen can house a 24-inch portable, it’s the pick. The Danby DDW1805EWP wins on the two things that stop many people from buying the GE: it’s about six inches narrower and costs less. If you’re washing for one or two, are short on room, or simply don’t want to spend up, the Danby handles daily dishes without complaint. Choose the GE for capacity and polish; choose the Danby to save money and floor space.

What to look for

• Match the footprint to your kitchen. Countertop units cost you worktop space; portables cost you floor space. Measure before you fall for specs.
• Capacity in place settings. Six settings suits one person; eight covers a couple; only a full-size portable keeps up with a family.
• Drying is the common weak point. Prioritize a heated or sanitize option if dry dishes matter, and plan to use rinse aid regardless.
• Noise matters more here. These machines live in the room with you, so a quieter portable is worth paying for in an open-plan space.
• Check the faucet fit. Quick-connect adapters suit standard faucets but often won’t attach to pull-out or specialty sprayers - verify yours first.
• Beware finish upcharges. A pricier ‘designer’ version of the same machine rarely cleans any better.

Our final take

For most small kitchens, the GE GPT225SSLSS is the best countertop-or-portable dishwasher you can buy: it cleans and dries like a built-in and only asks for a bit of floor space and a slightly higher price. If that’s too big or too dear, the 18-inch Danby DDW1805EWP delivers the essentials for less. Reserve the countertop DDW631SDB for genuinely space-starved, one-person setups, and pass on the SPT SD-9263SS, whose residual heat drying and side-sprayer leak warning undercut the portable idea. Buy for your space first, your budget second, and keep a bottle of rinse aid on hand whichever you pick.
