Quick Recap: A Plastic vs Stainless Steel Dishwasher Tub
Don’t let dishwashers fool you. While they seem like simple machines, there are a few nuances that differentiate a good dishwasher from a great dishwasher. A major detail that’s overlooked is the dishwasher tub.
A dishwasher tub not only determines how clean your dishes get, but also influences the product's lifespan and performance. And for the dishwashing tub to be performing powerfully and efficiently, one choice is considered better than the other. We're of course talking about the stainless steel vs plastic dishwasher tub debate. Find out which tub material is superior, whether a dishwasher with a stainless steel tub is worth the extra cost, and when opting for a dishwasher with a plastic tub is the better option with this handy guide.

Shop NowWhy a Dishwasher with a Stainless Steel Tub Is Superior
A dishwasher tub material is probably not something you think about unless you're choosing a brand-new dishwasher. But let's emphasize this point before going too far: a dishwasher with a stainless steel tub is (most likely) superior.
That's not just arrogance from premium brands and their users. A stainless steel dishwasher tub has plenty of advantages compared to a plastic tub.
For example, a dishwasher with a stainless steel tub is generally more:
- Durable: They're made from much stronger material than plastic so they're less likely to crack or dent and stand up to high temperatures.
- Long-Lasting: They're resistant to rust and corrosion, especially in areas where hard water can affect dishwashers.
- Hygienic: Stainless steel is more resistant to the growth of bacteria and mold, meaning a stainless steel tub helps keep your dishes cleaner and reduces the risk of odors.
- Insulated: Stainless steel is a good insulator and can keep your dishwasher running more quietly during operation.
Now let's explore these types of dishwashers in more detail by explaining the benefits of stainless steel dishwasher tub finishes compared to plastic interiors.
Higher Dishwasher Durability
Stainless steel is an alloy (typically a mix of iron, chromium, and nickel). This combination creates a hard, strong material, which, when exposed constantly to high temperatures or frequent tumbling, is better at resisting higher temperatures than plastic tubs. Stainless steel can rust, but most dishwashing machines these days are specially treated to withstand rust and corrosion. Specifically, chromium added to the mixture reacts with oxygen, forming a thin layer of protection against rust and corrosion caused by moisture, detergent, and minerals in hard water.
Dryer Dishes
Dishes are drier with stainless steel tubs because the material retains more heat than plastic. This heat is a crucial part of the drying process. During the drying cycle, the dishwasher's heating element raises the air temperature within the tub. This hot air loosens and evaporates water droplets from the dishes, which run off dishes (it’s what manufacturers like to call condensation drying).
Lower Dishwasher Noise Ratings
Stainless steel is a denser material than plastic, which is good because it dampens vibrations and sound waves created during the wash cycle, reducing the noise level of a dishwasher.
At the same time, it acts as a sound barrier. Sound waves travel through the tub walls, and some rebound back into the cavity. But stainless steel keeps the sound waves contained within the tub, instead of letting it out of the machine. Plus, stainless steel's rigidity helps minimize the tub's resonance during a wash cycle. Its sturdier build also dampens these resonances.
The Price of a Dishwasher with a Stainless Steel Tub
Price is the biggest tradeoff and a major reason homeowners might reconsider a dishwasher with a stainless steel tub. Generally, a dishwasher with a stainless steel tub costs more than that with a plastic tub.
When it comes to plastic vs stainless steel dishwasher tubs, you can expect to pay between $100 to several hundred dollars more for a dishwasher model with a stainless steel tub. If you're set on owning a dishwasher with a stainless steel tub, consider your budget carefully before buying one.

When to Choose a Dishwasher with a Plastic Tub
Not all households have a big budget for dishwashers. In these cases, choosing a dishwasher with a plastic tub may be more reasonable.
Here’s a summary of the positive sides of a dishwasher with a plastic interior and when it's better to choose a plastic tub over a stainless steel one in a dishwasher.
- There's a lighter need for dishwashing. Households with lighter dishwashing needs can make do with a plastic tub dishwasher. The durability of stainless steel might not be so critical if you're not washing heavily soiled pots and pans regularly. Plastic tubs handle lighter cleaning tasks adequately.
- Affordability is more of a priority. When weighing the pros and cons of plastic tub dishwasher models, the main benefit is affordability. If budget is the main concern for buyers not wanting a high-performance model, a plastic tub option offers significant cost savings.
- Your kitchen habits are more hands-on. If wet dishes are less of a concern for you, a plastic tub dishwasher is more than adequate for your needs. While these models won’t get dishes as dry s stainless steel counterparts, there are plenty of models on the market that with added features to dry dishes.

Quick Recap: A Plastic vs. Stainless Steel Dishwasher Tub
Let’s sum up the comparison between plastic and stainless steel dishwashers.
| Tub Material | Pro | Con |
|---|---|---|
| Stainless Steel | ✅ Highly resistant to cracking, warping, and corrosion, leading to a longer lifespan. ✅ Heats water to higher temperatures for a more effective clean. ✅ Denser material dampens noise and vibrations for a quieter dishwasher. ✅ Stainless steel resists stains and is easier to clean. ✅ Maintains consistent water temperature throughout the wash cycle. | ✖ Significantly more expensive than plastic tub models. ✖ The surface can be scratched with abrasive cleaning or utensils. ✖ This doesn't directly affect drying performance (both rely on heating elements and venting). |
| Plastic | ✅ The most budget-friendly option. ✅ May be less susceptible to denting from everyday use. ✅ No impact on air-drying, regardless of material. | ✖ More susceptible to cracking and warping over time, especially with hot water and heavy use. ✖ May need to be replaced sooner than a stainless steel tub. ✖ Doesn’t maintain water temperature as effectively as stainless steel. ✖ Plastic tubs tend to lead to louder dishwashers. ✖Pla stic absorb stains from food or hard water minerals. |
About Hybrid Dishwasher Tubs
Hybrid dishwasher tubs combine stainless steel and plastic. The exact design of a hybrid can vary between manufacturers, but usually, the base and lower portions (where the wash cycle happens) are made of stainless steel. Meanwhile, the upper parts, like the walls and interior trim, might be made of plastic.
A hybrid machine offers a compromise for those wanting the advantages of stainless steel but without the price tag. Check out the following pros and cons of a hybrid dishwasher tub:
✅ Generally more affordable than a full stainless steel tub
✅ More durable than plastic
✅ Considerable heat retention
✖ The plastic parts can get easily scratched
✖ There's less insulation
✖ Not all stainless steel benefits are available in a hybrid model
✖ Hybrid tubs might be less common so you have fewer choices
