Our take on the Whirlpool 18-inch Small Space Compact Built-In Dishwasher

The Whirlpool WDFS5118SS is an 18-inch built-in dishwasher made for narrow cabinet openings in apartments, studio kitchens and bar areas. It holds 8 place settings, runs at 48 dBA, and offers five programs including Quick Wash and Half Load, with a stainless steel tub and Sensor Wash. It is ADA-compliant and ENERGY STAR certified. Against 24-inch full-size machines it trades capacity for fit, and against other 18-inch models it stands out on quiet operation and a stainless interior rather than on cycle variety.

What reviewers say

Owners of 18-inch Whirlpool dishwashers generally report solid cleaning for the size and appreciate how quietly it runs in open-plan spaces. Complaints center on limited room for large cookware and on drying performance, which is typical of compact units without a heated dry boost.

  • NoisePraisedReviewers note it runs quietly enough for open kitchens and small apartments.
  • DryingCriticisedUsers report plastic items and cups stay wet at the end of a cycle.

Questions and answers

Will it fit a standard 18-inch cabinet opening?
Yes. It is built for 18-inch-wide cabinet cutouts and is ADA-compliant, so it works under lower counters too. Measure your opening and check the water and power connections before ordering.
How many place settings does it hold?
Eight place settings. That suits one or two people running a load most days, but a family cooking large meals will fill it fast.
Does it have a quick cycle?
Yes. Quick Wash is one of five programs, and Half Load lets you run a partial load without wasting water.
Is it quiet enough for an open-plan kitchen?
At 48 dBA it is quiet for a compact dishwasher and should not interrupt conversation in an adjacent room.
Does it need a special installation?
It is a built-under model, so it needs a cabinet opening, a nearby water supply and a drain. Professional installation is recommended for the panel and connections.
How does it compare with a 24-inch dishwasher?
It gives up roughly a third of the capacity and some rack flexibility, but it is the only option where a full-size unit will not fit. Its quiet rating and stainless tub compare well with other 18-inch models.
