18 inches wide small dishwasher: picks and trade-offs

If you need an 18 inches wide small dishwasher for a studio, apartment or narrow galley kitchen, the decision comes down to fit, noise and how many place settings you wash at once. Lowe's describes compact dishwashers as usually 18 inches wide and says built-in models typically hold 12 to 16 place settings, so an 18-inch unit trades capacity for space.

How we researched

This guide compares eight Amazon listings for 18-inch built-in dishwashers, alongside nine search results: retailer pages, roundup articles and one owner discussion. We used the manufacturer and retailer specifications shown in those results, the star ratings and review counts listed on Amazon, and the price tier of each listing. This guide compares products using manufacturer specifications, current Amazon listings and owner reviews; we did not test them hands-on.

Short answer

Start with the Honeywell 18 Inch Dishwasher with 8 place settings if you want the capacity stated in the listing title and a 4.2-star rating on Amazon. Choose the Midea 18 Inch Built-in Dishwasher if you care most about a large base of owner ratings, even though its average is lower. Every listing here falls in the over $300 price tier.

Buying criteria, in order of weight

1. Fit: an 18-inch width and a built-in installation. Every Amazon listing we compared is a built-in model, so check your cabinet opening and utility connections before you buy.
2. Capacity: place settings, where the listing states them.
3. Noise: decibel rating, where listed. One 18-inch front-control listing in the search results gives a 49 dBA sound level.
4. Owner feedback: Amazon star rating and the number of ratings behind it.
5. Price tier: over $300, $100 to $300, or under $100.

How we chose

We weighted fit and capacity first, then noise, then owner feedback, and price last because it does not change the job a dishwasher does. The evidence is manufacturer and retailer specifications from the search results, Amazon listing data, and a few owner comments in one Reddit thread. Nobody on our side used these machines, so we make no claims about how they perform in a kitchen. We will update this guide when listings or price tiers change.

Honeywell 18 Inch Dishwasher with 8 place settings

This model fits you if you want a stated capacity and a rating you can read at a glance. The listing title says 8 place settings, and it shows 4.2 stars on Amazon from 131 ratings. Sites in this market are not agreed on how many settings compact units hold, so a stated number on the listing is worth checking against your own loads.

The drawback is that our data does not include a sound level or cycle count for this listing, and 131 ratings is a moderate sample.

Disclosure: the site may earn a commission if you buy through the links in this guide, and the price does not change for you.

Midea 18 Inch Built-in Dishwasher

This model fits you if you want the most owner feedback before you buy. The listing shows 4.1 stars on Amazon from 562 ratings, the largest sample among the listings we compared, and it shows 100+ bought in the past month. You get more evidence about how owners feel about it, though the average is lower than the Honeywell's.

The drawback is that place settings and sound level are not listed in our data for this model. If capacity matters to you, ask the seller or read the spec sheet before you commit.

COMFEE' 18 Inch Built-in Dishwasher

This model fits you if you put the highest star rating first. The COMFEE' listing shows 4.3 stars on Amazon from 45 ratings, and 200+ bought in the past month. Three COMFEE' listings share the same rating and rating count, and our data does not explain how they differ, so compare their specs on each page.

The drawback is the small sample. With 45 ratings, a handful of reviews can move the average, so read the recent comments before you trust the number.

Who should skip these

Skip the 18-inch built-ins if you need more than 16 place settings, since the Lowe's figure suggests built-in capacity tops out in that range. The Sharp SDW4523MS listing has 3.9 stars from 11 ratings, which is too few to judge. If you need a unit that moves between rooms or sits on a counter, see our best portable 18 inch dishwasher guide or our countertop dishwasher picks by price range.

What owners say

In one Reddit thread asking for 18-inch recommendations, the first comment warns that most people will say do not bother. That is one owner's view, not a pattern, but it points to a common concern: small machines are a trade-off, and buyers who choose one usually know what they gave up. A roundup of 18-inch models names a Bosch 800 Series and a GE Profile 18-inch built-in, which are brands you can check if the Amazon options do not fit your kitchen.

How to choose

If you want a stated capacity and a 4.2-star rating, pick the Honeywell listing. If you want the largest owner sample, pick the Midea listing. If you want the highest rating and accept a small sample, look at the COMFEE' listing. If you need a sound level, check the spec sheet before you buy, because the Amazon listings here do not give one. Before you order any built-in, check your lease and local rules about installation, and measure your opening.

FAQ

Is an 18-inch dishwasher worth buying for a small kitchen?

It can be, if the capacity suits your daily dishes. Built-in models are often rated for 12 to 16 place settings, so an 18-inch unit is a trade-off, not a downgrade you should ignore.

What should I check before buying one?

Measure the opening, confirm the installation type, and find the place settings and sound level on the spec sheet. Check your lease and local rules before you install anything.

Are the star ratings enough to decide?

No. A 4.3 rating from 45 reviews is less certain than a 4.1 from 562, so look at the number of ratings as well as the average.

Conclusion

For most small kitchens, the Honeywell listing gives you the clearest capacity figure, and the Midea listing gives you the deepest owner sample. Confirm the fit and sound level before you buy, and treat a small rating count as a reason to read more reviews, not as a verdict.
