Choosing the right dishwasher can save you time, reduce water usage, and improve your kitchen experience. With so many models, features, and price points available, it can feel overwhelming to decide which one is right for your home.
This dishwasher buying guide will walk you through everything you need to know, including size, types, pricing, features, and the most reliable brands so you can make a confident decision.
Dishwasher Size Guide (18 vs 24 Inch)
Selecting the right size is the first and most important step.
Standard 24-Inch Dishwashers
These are the most common and best suited for families or households that run frequent loads. They typically hold 12 to 16 place settings and fit standard kitchen layouts.
Compact 18-Inch Dishwashers
If you live in an apartment or have a smaller kitchen, an 18 inch dishwasher is a great option. It saves space while still offering solid cleaning performance.
Portable and Countertop Dishwashers
Portable and countertop models are ideal for renters or kitchens without built-in connections. They are easy to install and require minimal space.

How Long Do Dishwashers Last?

Do You Need to Pre-Rinse Your Dishes?
One common question when choosing a dishwasher is whether you need to rinse dishes before loading them.
Modern dishwashers are designed to handle food residue, but performance depends on the model.
- Basic models may require light rinsing to prevent clogs and ensure proper cleaning
- Higher-end models often include advanced filtration systems
If you prefer not to rinse dishes, look for models with a hard food disposer. This feature grinds food particles, preventing them from redepositing on dishes and reducing maintenance.
This is a valuable upgrade if convenience is a priority.
Stainless Steel vs Plastic Tub
Choosing the right tub material affects durability and performance.
Stainless Steel Tub
- More durable
- Quieter operation
- Better drying performance
Plastic Tub
- Lower upfront cost
- Lightweight
- Less effective drying
Which One Should You Choose?
If your budget allows, stainless steel is the better long term investment. Plastic tubs are suitable for budget conscious buyers.
Dishwasher Interior and Rack Design
Beyond size, the internal layout of a dishwasher plays a big role in everyday usability.
Why a Third Rack Matters
A third rack provides additional space for utensils, small items, and flatware. This helps:
- Free up space in the lower racks
- Improve cleaning organization
- Increase overall capacity without increasing size
If you frequently run full loads, a third rack can make a noticeable difference.
