How to Choose the Right Dishwasher for Your Home
A dishwasher is one of the most-used appliances in any kitchen, yet buying one can feel overwhelming given the range of features, sizes, and price points available. This guide walks you through every key decision so you can shop with confidence.
Step 1: Determine the Right Size
Most built-in dishwashers are 24-inch wide — the standard size that fits the majority of kitchen cabinetry openings. If space is limited, 18-inch compact models are available and work well for apartments or small households. For very tight spaces, countertop dishwashers connect directly to your faucet and require no installation at all.
Step 2: Choose a Tub Material
- Stainless steel tub: Dries dishes more effectively (retains heat), resists odors and staining, and tends to last longer. Found in mid-range to premium models.
- Plastic tub: Common in budget models. Works fine but doesn't retain heat as well, which can leave dishes wetter after a cycle.
Step 3: Understand Wash Cycles & Cleaning Performance
All dishwashers include a standard wash cycle, but look for these additional options based on your needs:
- Heavy/Pots & Pans cycle: Extended, hotter wash for heavily soiled items
- Quick/Express cycle: 30–60 minute cycle for lightly soiled loads
- Sanitize cycle: Reaches 155°F+ to kill bacteria — especially useful for baby items or cutting boards
- Delay start: Run the dishwasher overnight during off-peak energy hours
- Half-load/top rack only: Conserves water and energy for smaller loads
Step 4: Evaluate Noise Level
Dishwasher noise is measured in decibels (dBA). Here's what the numbers mean in practice:
| Noise Level | Rating | Best For |
|---|---|---|
| Under 44 dBA | Very quiet (premium) | Open floor plans, night running |
| 44–49 dBA | Quiet (mid-range) | Most households |
| 50–55 dBA | Moderate (budget) | Separated kitchens |
| Over 55 dBA | Noisy | Not recommended for open layouts |
Step 5: Check the Rack Configuration
Interior flexibility determines how many dishes you can fit and how easily. Look for:
- Adjustable upper rack: Accommodates tall glasses and pot lids
- Third rack (cutlery tray): Frees up space in the lower basket; handles spatulas and long utensils flat
- Fold-down tines: Let you fit larger items like sheet pans and mixing bowls
Step 6: Consider Drying Performance
Drying technology varies significantly between models:
- Heated dry: Uses an electric element — effective but uses more energy
- Condensation drying: Uses residual heat and the stainless tub; energy-efficient but slower
- Fan-assisted drying: A fan circulates air — better results than condensation alone
- Zeolite or crystal drying: Found in premium brands; absorbs moisture and releases heat for excellent drying without extra energy
Step 7: Budget Guidelines
- Under $500: Plastic tub, basic cycles, moderate noise — fine for budget-conscious buyers
- $500–$900: Stainless tub, third rack, quieter operation — the sweet spot for most households
- $900–$1,500+: Premium drying, ultra-quiet, advanced sensors, smart connectivity
Final Checklist Before You Buy
- Measure your cabinet opening (width, height, and depth)
- Check the noise rating — aim for 48 dBA or below
- Confirm stainless steel tub if drying performance matters to you
- Look for an adjustable upper rack and third rack if you run large or varied loads
- Check Energy Star certification to minimize operating costs
