Most homeowners who buy a steel shed flat package are unaware that flooring materials are not included in the kit. Thankfully, you can hire a contractor specializing in sheds to build one for you. However, if you want to do it yourself, you should read this article thoroughly. 

In the past, gravel was the common choice for shed flooring. However, it’s not the most popular anymore. 

We have listed some of the most common shed flooring options in this article: 


Many sheds have plywood. It is a popular choice because it is durable and is easy to install. Just make sure you get the right plywood thickness for your needs. 

This option is inexpensive and can be purchased at your local home improvement store. 


Many contractors utilize OSB for sheds. It is not plywood, but they have similarities. It is less expensive than plywood, but it is sturdier. You can nail or screw it into place and then cover it with carpet and decorate it with paint.

OSB is made from wood chips and sawdust and is easier to work with. It is more flexible and is a versatile material. If you want a robust and lightweight flooring material, OSB is an excellent choice. This option is perfect if you are on a budget and have little experience with shed flooring.

Many consider this a healthier choice because it has a lesser amount of formaldehyde than plywood. However, you do not have to worry if you plan to use plywood because, since 2019, they have been made to contain lesser amounts of formaldehyde. 


This flooring material is another popular option. Most DIY warriors would pour concrete and level it out, but you should understand more about concrete before attempting this. 

The thickness and quality of concrete vary according to the area of installation. You should consider the weather conditions, high water tables, and soil types. To achieve the right consistency, you might have to mix different bagged concrete and add water. This process can be time-consuming, so you might want to seek help from a professional.

Medium-quality concrete is made of a mixture of sand, gravel, and cement. It is durable, but it will not be suitable for freezing weather. You can modify it to make it last.

Experienced contractors suggest that the best way to create a concrete floor is to build a wooden frame and level it. You can use plastic sheeting to avoid pooling water and concrete underneath.

Many people choose this because it is cheap and easy to install. However, concrete is porous and will crack. Also, it is not aesthetically pleasing. It is the best option to add a garage to your house.


There are numerous flooring options for you to choose from. If you want the best one, you should think about your budget, climate condition, quality of work, and aesthetic appeal. Do some research, and you will be able to choose the most suitable material for your shed.
