1. Bosch SPE68U55UC - 44 dB - $949

Bosch has made a name for itself as the quietest dishwasher brand. For the best 18 inch dishwasher that's also whisper-quiet, consider the Bosch SPE68U55UC, operating at an ultra-quiet 44 decibels. (To learn more about dishwasher operation noise, check out our article on dishwasher decibel levels.) This ADA compliant Bosch model comes in stainless steel, priced at $949.

This 18" dishwasher offers a ton of premium features. It has a built-in water softener to reduce water spots, and Bosch's AquaStop Plus leak protection reduces damage from potential leaks as soon as they start. The stainless steel tub stays odor-free and reduces noise compared to plastic tubs. A third rack gives you more room for utensils and small items (boosting total capacity by 30%), while the RackMatic middle rack is adjustable to make room for tall or bulky items on the lower rack. 

Bosch is known for their dishwashers, so it's no wonder that this model and another Bosch model made it to our list! The EuroTub design is also shallow enough that it will install flush with your counters for a built in, integrated look. 



  • 6 Programs: Auto, Delicate/Economy Wash, Power Scrub Plus, Quick Wash, Regular, Rinse & Hold

  • 3 Options: Extra Dry, Half Load, Sanitation, Delay Start (24 Hours)

  • 10 place settings capacity

  • Third rack design with adjustable RackMatic middle rack

  • Stainless steel tub

  • Front controls with pocket handle

  • Built-in water softener

  • AquaStop® Plus 4-Part Leak Protection Works 24/7

2. GE Profile PDT145SSLSS - 47 dB - $999

The hidden top controls and pocket handle of the GE Profile PDT145SSLSS dishwasher give it a premium look. The low profile installation works well for 34" tall countertops and raised sub floors. If you're looking for a smart dishwasher, you can add GE's Connect Plus module to receive alerts when a cycle is finished, among other features.

Overall, this 18 inch dishwasher has simple controls and options. The upper rack is adjustable, while the lower rack has fold down tines and room for up to eight place settings. The Piranha hard food disposer pulverizes large food particles to prevent debris from clogging the wash arms. The NSF-certified Sanitize option will use a high-heat rinse to reduce bacteria by 99.999%, ideal for baby bottles and other items that you want to be as clean as possible.

If you're looking for an easy to use dishwasher with a premium exterior design, this GE Profile model may be the best 18 inch dishwasher for you! It's available in black, white, and stainless steel.



  • 3 Programs: Heavy, AutoSense, Light

  • 3 Options: Boost (Wash Temp), Sanitize, Delay Start (12 Hours)

  • 8 place settings capacity

  • Stainless steel tub

  • Top controls with pocket handle

3. Frigidaire FFBD1831US - 52 dB - $799

Next up on our list of the best 18 inch dishwashers of the year is the Frigidaire FFBD1831US, a basic model available in stainless at $799 and black or white at $749. If you're looking for an ADA compliant dishwasher at a lower price point than the GE Profile model above, consider this ADA compliant Frigidaire model.

With easy-access front controls and six wash programs, including China/Crystal and Energy Saver, choosing the right wash cycle for each load is a snap. The removable, self-cleaning filter helps keep the wash water clean of food particles and debris to truly clean your dishes. The front controls show the time remaining so you'll never have to guess how much longer the cycle will last.

This dishwasher is easy to use and includes handy features like Heat Dry, ideal for loads with lots of plasticware. This model was updated from the FFBD1821MS in 2019, so it has a slightly nicer control layout and improved features. It's not the quietest model at 52 decibels, but it's definitely quieter than older dishwashers!



  • 6 Programs: Normal, Heavy, Light, China/Crystal, Energy Saver, Rinse Only

  • 4 Options: Sanitize, Hi-Temp, Heat Dry, Delay Start (24 Hours)

  • 8 place settings capacity

  • ADA Compliant

  • Front controls with pocket handle

  • Stainless steel tub

4. Whirlpool WDF518SAHM - 50 dB - $899

Available in stainless steel at $899 and white or black at $799, the Whirlpool WDF518SAHM is another ADA-compliant option among the best 18 inch dishwashers! With 50 decibel operation, it's not the quietest dishwasher around, but noticeably quieter than older models and falls below the typical conversation level of 60 dBA.

Convenient features like the adjustable upper rack and Quick Wash program help you make the most out of a smaller dishwasher. The touch screen controls are a nice upgrade from more basic front control dishwashers, too. The Hi Temp Wash option is a great choice for items like baby bottles. Each rack features its own spray arm to ensure a thorough clean.

Heated Dry is a feature many people miss from their old dishwashers. It uses more energy but can help dry dishes more quickly. Compared to the Frigidaire model above at the same price that also has heated dry, this model has a slightly sleeker control panel but fewer wash programs. 



  • 5 Programs: Heavy, Normal, Quick Wash, Rinse Only, Light/China

  • 3 Options: Delay Start (24 Hours), Heated Dry, Hi Temp Wash

  • ADA Compliant

  • 8 place settings capacity

  • Stainless steel tub

  • Front controls with pocket handle

  • Adjustable upper rack

5. Bosch SPX68U55UC - 44 db - $1,049

Last but not least in our reviews of the best 18 inch dishwasher models is the Bosch SPX68U55UC, a stainless steel hidden top control model with a bar handle available at $1,049. Bosch excels at providing a premium look, although you can save money by going for the other Bosch model in our review with front controls and a pocket handle. 

A third rack is a great way to get more usable space in your dishwasher, plus the RackMatic adjustable upper rack can accommodate big pots and pans in the lower rack or lots of mid-size items in the lower and middle rack. The V-shaped third rack leaves you room in the upper rack for taller items, too. Bosch's AquaStop Plus leak protection helps prevent leaks from becoming total kitchen disasters - another great feature to have in a dishwasher!

Not having the space for a full-size dishwasher doesn't mean you have to sacrifice premium features and styling, and this Bosch 18 inch dishwasher is proof that you can have it all.



  • 6 Programs: Auto, Delicate/Economy Wash, Power Scrub Plus, Quick Wash, Regular, Rinse & Hold

  • 4 Options: Extra Dry, Half Load, Sanitize, Delay Start (24 Hours)

  • 10 place settings capacity

  • ADA compliant

  • Third rack design plus RackMatic adjustable upper rack

  • Stainless steel EuroTub

  • AquaStop® Plus 4-Part Leak Protection Works 24/7

  • Water softener

  • Flexible silverware basket

  • Hidden top controls and bar handle

That's it for our list of the top five best 18 inch dishwashers of 2020. If you're looking for the most place settings capacity, check out the Bosch models (#1 and #5), which have 10 place settings rather than 8. If you prefer the smooth look of hidden top controls, check out the GE Profile model (#2), or the last Bosch model (#5). Bosch is the overall winner in terms of high-end features, but even the cheapest models on our list have Energy Star ratings, durable nylon-coated racks, and stainless steel tubs.
