Plastic vs Stainless Steel Dishwasher Tub

DIshwashers come in two formats: Plastic and stainless steel. The interior part is called the dishwasher tub that is made of plastic or stainless steel these days.

Plastic can never be best than stainless steel. It is because plastic is not as durable as steel. Plastic also has many other disadvantages over stainless steel.

Plastic dishwashers cannot bear high temperatures during the drying process and consumer extra electricity. These can increase your electricity bill.

It is the best choice to spend some extra money on stainless steel dishwashers for one time and save money later.

Here we discuss in detail which one is best and how?

Stainless Steel Dishwasher Tub Pros and Cons

If you are deciding to buy a dishwasher and confused about whether to buy plastic or stainless steel then it is best if you have a budget to buy a steel one.

Following advantages and disadvantages of a steel tub will help you in clearing your mind.


This type of dishwasher has a lot of benefits and is more efficient.

Corrosion Resistant

Corrosion Resistant

A dishwasher made of stainless steel resists corrosion and retains its properties for a long time as compared to plastic dishwashers.



These are very durable. These can bear very high temperatures and water is heated up to maximum temperature for better cleaning and to die bacteria that are harmful to your health.

These bacteria are mostly not killed during hand washing because we cannot use very hot water during it.

High Efficiency

Dishwashers with stainless steel tubs can absorb and retain more heat as compared to plastic. During the process of drying this heat is used and as a result, energy is saved.

In this way, these can save about 200 watts of electricity during this process. If you wash dishes daily it is a great saving. So, they have high efficiency.

Noise Absorption

Noise Absorption

Noise is produced by the water when washing dishes. A stainless steel tub has the ability to absorb maximum noise by its walls. This thing improves your user experience.

Better Cleaning

Better Cleaning

As these dishwashers can bear very high temperatures, water can be boiled at high temperatures. 160 Degree Fahrenheit is bearable by stainless steel.

Hot water helps to kill bacteria in dishes and clean dishes in a more better way.


Stainless steel dishwasher tubs have almost no cons but we will discuss two that you should also know.


If your water is very hard then there is a risk that your dishwasher will be caught in stains and you have to wash it that is hard work.

In such cases, it is recommended to use a water softener if not present in your dishwasher.

High Price

Stainless steel dishwashers have slightly high prices than plastic dishwashers. Although the prices are high, they have benefits also that are greater than the price.

Pros and Cons of Plastic Dishwasher Tub

Plastic dishwasher tub has small pros as compared to steel ones.

We will discuss both the pros and cons to help you understand the difference.


The two big pros of Plastic Dishwasher are:

No stains

A plastic dishwasher tub does not catch stains even if the water is hard. So you have no need to clean it frequently or use a water softener.

Low Price

As these dishwashers are made up of plastic material so their prices are low as compared to steel ones. If you have a small budget then you can go for it.


These have the following two disadvantages.

More Noise

Although the new models in plastic dishwashers have some extra layers of insulation still they cannot absorb as much noise as stainless steel, You have to bear a little more noise when the dishwasher will be running.

More Energy Consumption

These dishwashers can neither bear nor retain heat because plastic is not very strong. More heat is used during the drying process that increases your electricity bill.

Our Suggestion

If you have budget then you must buy a stainless steel dishwasher because it will reduce your electricity and improve your user experience.

Plastic dishwashers are not so bad that you should not buy them. If you have a small budget then you should go for a plastic one.
