Perhaps you’ve never considered it, but the shed flooring may be the most important part of your shed. After all, it’s technically the part of your shed that gets used the most. If your shed floor is in weak or poor condition, your shed is essentially useless.

In this article, we discuss the best options for shed sub-flooring as well as great options for finished shed flooring. Whether you’re looking to buy a new shed or upgrade the shed flooring of a building you already own, our aim is to leave you better informed about your options when it comes to shed flooring.

4 Shed Sub-flooring Options

The subfloor of your shed is a crucial part of the shed structure. Having a solid subfloor will give you the ability to store heavy items like tractors, as well as heavy gym equipment, if you use your shed as a home gym. If you’d like to learn more about the high-quality materials that we use, such as 5/8″ or 3/4″ pressure-treated polywood flooring on sheds and garages, check out our high-quality shed features page. But here are a few of the best options for your shed’s sub-flooring.

1. Plywood

Pressure-treated plywood is one of the most common shed flooring options, and for good reason. ⅝ ” to ¾” plywood is the most common subflooring shed builders use since plywood that’s been pressure-treated is resistant to moisture and rot and will last for quite a long time. It also features a smooth finish that’s easy to sweep and clean. This style of flooring also makes it easy to install carpet and vinyl planking, making it a great choice for finished sheds.

Plywood Shed Flooring Pros:

Durable and moisture-resistant when pressure-treated
Relatively strong: Usually can support around 20 lbs per square foot
Easy to clean
Easy to finish with carpet, paint, or vinyl flooring

Plywood Shed Flooring Cons:

Not as durable and strong as concrete
Often more expensive than OSB

2. OSB

OSB is one of the cheapest subfloor options, and is typically seen as a lower-cost alternative to plywood. It isn’t quite as strong as plywood, and typically doesn’t hold up to moisture as well as plywood. However, if you’re looking for a low-cost flooring option and don’t mind how it looks, OSB could be a viable option.

OSB Shed Flooring Pros:

It can usually be found at a lower cost than plywood

OSB Shed Flooring Cons

Not moisture resistant
Not as durable as plywood
Doesn’t look as good as plywood

3. Composite Deck Boards

Using composite decking as a shed floor without any additional subfloor is not a popular option, but can be a good choice in certain situations. Composite deck boards are quite durable and are very moisture resistant.

If you plan to use your shed in a way that requires it to be washed regularly, the gaps between the deck boards would allow the water to drain away. Deck boards, however, aren’t as rigid as plywood, so it would be a good idea to add extra runners to support the flooring.

Composite Deck Boards Pros

Very durable
Moisture resistant
Excellent floor drainage for wet areas
Gives a unique look

Composite Deck Boards Cons

Can be expensive
Not as rigid as other options
Shouldn’t be finished with carpet or vinyl flooring

For some composite deck board options, check out Home Depot or Lowe’s.

4. Concrete

The strongest flooring option is to simply use a concrete slab as the flooring. In terms of strength and durability, nothing beats concrete. It can be expensive, but since the concrete can be both the shed foundation and the flooring, it can be a cost-effective option.

To use concrete as the shed floor, the shed is essentially fastened to the concrete pad, which makes the shed immovable. Some people may see this as a downside, but it also makes the shed quite sturdy.

Concrete Shed Flooring Pros

Very durable
Completely moisture resistant
Very strong

Concrete Shed Flooring Cons

Can be expensive
Doesn’t give a “warm” feel like wood flooring
Makes the shed unmovable

5 Popular Finished Shed Flooring Ideas

Many shed owners simply leave their shed subflooring exposed since sheds are typically used as storage or as workshops. However, more and more people are choosing to finish their sheds and use them as living spaces, shed homes, or home offices. Check out our shed ideas article for inspiration and to see how others have finished their shed floors. But here are a few great finished shed flooring options:

1. Painted or Stained

The easiest and cheapest way to finish your shed floor is to paint or stain it. This is easiest if your shed flooring is wood, but concrete can also be stained. Not only does paint improve the look of a shed’s interior, but it also helps protect the flooring, especially if the shed flooring is made from untreated wood.

Painted or Stained Flooring Pros

Cheap and easy
Easy to remodel

Painted or Stained Flooring Cons

Minimal upgrade

2.Vinyl Planking

Vinyl plank flooring is one of the most popular flooring options for a variety of living spaces, including homes, offices, and finished sheds. This vinyl plank flooring both looks great and is quite durable. Vinyl planking, however, is susceptible to temperature fluctuations and should only be used if your shed is climate-controlled.

Vinyl Plank Flooring Pros

Looks great
Durable and reliable

Vinyl Plank Flooring Cons

Expensive compared to some other options
Susceptible to temperature fluctuations

Vinyl planking can be found at most large hardware stores as well as stores such as Decks Direct.

3. Rubber Tiles

Rubber tiles are popular in garages and gyms, but can also be used in sheds. Rubber tiles offer both durability and protection for the subfloor, but also make the floor a bit softer and forgiving than bare wood.

Rubber Tile Flooring Pros

Various color options
Great protection for the subfloor
Gives the shed subfloor extra protection

Rubber Tile Flooring Cons

Time-consuming installation
Joins can allow water and dirt through
Can be slippery when wet

4. Epoxy

Epoxy can be applied to both concrete and wood flooring, and is a great way to upgrade the look and durability of a shed floor. This type of finish is relatively easy to apply and is popular with DIYers.

Epoxy Flooring Pros

Easy to apply
Lots of color and style options
Great protection for both concrete and wood flooring

Epoxy Flooring Cons

It isn’t a great option for areas with high temperature fluctuations
Is susceptible to chipping and discoloration

5. Carpet

One of the easiest ways to upgrade a shed’s interior is by adding carpet. Carpet is a great choice if you happen to have some extra material from another project or love the warm feel of carpet. However, carpet isn’t the most durable choice and isn’t the best option for workshop sheds

Carpet Flooring Pros

Can be a cheap and easy flooring option
Gives a warm and home-like feel

Carpet Flooring Cons

Not a durable option

Should A Shed Floor be Insulated?

Not all sheds need to have an insulated floor, but if you plan to heat your shed, it’s probably a good idea. If you plan to finish out your shed and add heating and cooling, your shed floor should be insulated. For more heating and insulating tips, visit our blog on how to heat a garage shed in winter.

Keep in mind that some shed flooring options, like vinyl planking and epoxy finishes, are best used if the shed is climate-controlled and the floor is insulated. Below are a few popular shed floor insulation options.

3 Shed Floor Insulation Options

Spray Foam Insulation

Spray foam insulation is the most popular shed floor insulation option, and the best overall choice. It’s the most durable and provides great R-value, even in small spaces. However, it isn’t the cheapest option, and it requires a sprayer to apply.

Batt Insulation

Batt insulation is one of the easiest types of insulation to install and is popular with DIYers. It’s also a low-cost option. It isn’t quite as effective as spray foam and isn’t as durable.

Foam Board Insulation

Foam board insulation is applied by cutting the board to a specific size and adding the board between the shed floor joists. This makes the installation a bit more tedious than the other options, as the pieces need to be precisely cut. However, it’s still a good option and relatively low cost.

Conclusion

Whether you’re buying a new shed or are upgrading the floor of an existing shed, it’s important to have a shed floor that’s both durable and serves your needs. We hope this article gives you the information you need to make a great choice for your next shed floor. What to design your own shed, cabin or garage to finish out yourself?
