Best Countertop Dishwasher: Top Picks and What to Look For

Countertop dishwashers are one of the most practical appliances for small apartments, RVs, dorm rooms, and anyone who wants dishwasher convenience without installation. Here's everything you need to know to choose the best countertop dishwasher for your needs.

What Is a Countertop Dishwasher?

A countertop dishwasher is a compact appliance that sits on your kitchen counter. Most models connect to the kitchen faucet via an adapter — no plumbing installation required. Some newer models have a built-in water tank, eliminating even the faucet connection.

What to Look for in a Countertop Dishwasher

Water Connection Type

• Faucet-connected: Connects via an adapter to your kitchen faucet. Most common. Requires a standard faucet thread.
• Built-in water tank: No faucet connection needed. You fill the tank manually. More flexible placement but requires refilling.

Capacity

Most countertop dishwashers hold 6 place settings — enough for 1–2 people's daily dishes. A place setting includes a dinner plate, salad plate, bowl, cup, and cutlery.

Wash Programs

Look for at least Normal, Heavy, and ECO cycles. Baby-Care and Glass cycles are useful bonuses. More programs give you more flexibility for different loads.

Drying Method

Most countertop dishwashers use air drying. Use rinse aid to improve drying performance — the Amazon Basics Rinse Aid (amzn.to/4v4Ts5b) significantly reduces water spots and speeds up air drying.

Noise Level

Countertop dishwashers typically run at 55–65 dB — louder than built-in models. If noise is a concern, check the manufacturer's dB rating before buying.

Dimensions

Measure your counter space before buying. Most countertop dishwashers are approximately 17–20" wide, 17–20" deep, and 17–20" tall. Make sure you have enough clearance above for the door to open.

Detergent for Countertop Dishwashers

Use standard dishwasher detergent — pods work well in countertop models. The Finish Powerball Dishwasher Pods (amzn.to/3RE929j) are pre-measured and effective. For countertop models, you may only need half a pod for lighter loads.

Maintenance

Clean the filter monthly and run a cleaning cycle with Affresh Dishwasher Cleaner Tablets (amzn.to/42P5MKQ) every 1–2 months to prevent odors and mineral buildup.

Is a Countertop Dishwasher Worth It?

For 1–2 people in a small space, absolutely. A countertop dishwasher saves time, uses less water than hand washing, and provides better hygiene through high-temperature washing. The no-installation models are especially compelling — you can take them with you when you move.
