The 8 Best 18-inch Dishwashers November, 2019 (And 2 Other Models)

This list made of the latest 18-inch dishwashers includes only dishwashers that satisfy these specs:

  • 18-Inch dishwashers are, for the vast majority, built-in models, but compact-enough for small kitchens
  • The narrow range we require to consider a model as an 18-inch dishwasher is between 17.5 and 18.5 inches
  • Expect a feature set slightly less impressive for these small dishwashers than on full-fledged units, but some 18-inch stainless-steel dishwashers still manage to have fitted many of the latest perks and scrubbing technologies associated with wider models. There are also a few portable (with casters) and panel-ready models in the 18-inch-wide category.
  • 18-inch dishwashers are the norm for any narrow or slimline models and may not be the quietest (given their smaller size), but we included decibel ratings when available, so you can choose wisely if noise levels are a concern.

Scanning through some of the Bosch SPX68U55UC's 81 total reviews, a lot of people appear to have been pleasantly surprised by how well it accommodates a variety of dish shapes and sizes, considering that it is, after all, an 18-inch built-in dishwasher with only 10 place settings (as opposed to the 14 place settings usually found on standard-size models). It has also been praised quite a lot for its cleaning ability, with some buyers even describing their dishes as ((Q))sparkling clean((Q)) right after being washed in this said unit.

However, what seems to set it apart from many others in this top 8 list of 18-inch models is the overwhelming positive feedback about it being a quiet dishwasher. Not a few reviews contain remarks about the SPX68U55UC being so quiet that their owners had to rely on the InfoLight feature (which indicates if a cycle is ongoing) to make sure that the unit was indeed running. Such a claim may potentially be too good to be true, but picture this: many 18-inch dishwashers in our database have already been praised for their quietness at a noise rating of around 55dB. This Bosch model, meanwhile, boasts a significantly-lower 44dB max noise level.

Perhaps the most common complaint about this dishwasher concerns its olfactory appeal. There have been complaints about it having an ((Q))overwhelming((Q)) bad odor, especially during the first several uses. It also doesn't dry dishes excellently, but this is a complaint we see a lot across dishwashers in general.

In the end, the SPX68U55UC has earned a 4-star rating. This just shows that it is really a strong contender if you're looking for a quiet 18 inch dishwasher, seeing that it's the best model in this specific subcategory (Learn how we rank items) with a confidence level of 97 (More on confidence levels).

This semi-integrated model from Frigidaire didn't make it as Alphachooser's second best 18-inch dishwasher 2019 of our top 8 18-inch dishwashers for nothing. It has secured a great number of reviews praising it for its physique, with its stainless steel finish (for the FFBD1821MS variant, at least) giving its exterior a sleek and modern look. Furthermore, praises for its cleaning ability come aplenty, even with its light cycle -- but note that most of the reviewers who've written this remark have also mentioned that they routinely pre-rinse extra-dirty dishes in the first place.

Opinions about the Frigidaire FFBD1821MS' noise level isn't as definitive, however. Some consumers have noted that it is ((Q))very quiet,((Q)) while some expressed wishes for it to be less noisy. As such, perhaps the most solid benchmark we can rely on at this point is really its 55dB noise rating, which is relatively-noisy, but its not unexpected for a semi-integrated compact dishwasher.

Common complaints found among its 1393 reviews involve the ((Q))wonky((Q)) silverware basket and this semi-integrated dishwasher's height (or lack thereof), which is not the tallest but is definitely taller than the category average. So if you're iffy about having a dishwasher that may potentially leave some space between it and the countertop, then we suggest that you take diligence in comparing measurements before taking the plunge.

In the end, the Frigidaire FFBD1821MS was able to traverse past its imperfections, winning an impressive number of fans in the process

The Frigidaire FFPD1821MW seems to pack quite a punch within its 18-inch body. The dishwasher has racked up 631 reviews across multiple sources, and its aggregated rating is at 4 stars. According to many of these customer feedback, it doesn't fail at delivering sparkling-clean dishes (granted, extremely-dirty dishes with dried-on gunk still have to be pre-rinsed). Some even reported that they feel like they're consuming less dishwasher compared to their previous models, and yet are getting better results. Furthermore, the Frigidaire FFPD1821MW has also been praised quite a lot for its looks, and the ((Q))easy-to-clean((Q)) stainless steel interior has gained it some fans, as well.

While it's nothing disruptive, this 18-inch dishwasher's 59dB noise rating isn't its most encouraging feature. It's true that models that veer away from the standard size tend to have higher noise ratings, but the FFPD1821MW clearly has a lot of customers wishing that it was a bit quieter. Another complaint we've seen more than a few times concern the silverware basket. Reviewers have pointed out that it feels quite wonky and that they wish it was bigger. Also, the silverware slots inside aren't too accommodating for larger utensils. Luckily, the slots can be removed in favor of having just a plain old basket.

Still, the Frigidaire FFPD1821MW appears to have shown customers all that it is capable of doing, which has left a lot of people satisfied, based on the reviews we have encountered. Due to this, it's been named as an Alphachooser good choice by our system (Learn how we rank items) with a 99 confidence level (More on confidence levels).
