If you don’t have any extra rooms in your house but you really want a home gym, the garden shed is a good option. But how much can you expect to pay for a shed that’s big enough to build a home gym? Keep reading to find out.
How much you can expect to pay for a gym sized shed really depends on the material and the size;
- Metal sheds cost anywhere from $500 to $2000. On average they cost about $700 for the smaller and around $1350 for the bigger sheds.
- Resin/plastic sheds can cost anywhere from $800 to $1800. Expect to pay $1000 to $1300 for a good one.
- Wooden sheds are at least $2000. Expect to pay $2500 for a small one up to $3500 for bigger shacks.

Which Type Of Shed Is Best For a Home Gym?
Before I answer the question, we have to think about which type of shed we want. Especially the material choice. Sheds are usually made from metal, wood or plastic. The material you choose, obviously has a big impact on the total price of the shed.
I’ve written a whole post about what the best material choice for a gym shed is. You can find it here (click).
To keep this short, here is the summary of that post;
“A wooden shed is the best option to build a gym in. Wooden sheds are the easiest to modify, look the best and have a pleasant indoor climate. They are quite expensive and require a lot of maintenance however. A good second choice is a resin shed. Resin has a few downsides like lack of customizability but are much cheaper and don’t require any maintenance.”

Which shed size is suitable for a home gym?
Besides the material, you have to get the right size. Too big isn’t really a problem. Too small certainly is. Too small means you can’t do all the exercises you want and/or fit all the equipment you want.

It all comes down to how much stuff you want to fit in your shed. The more gym equipment you need/want, the bigger your shed has to be to fit it all in and to be able to use it.
With a basic free weights setup, an 8’ by 8’ shed is the absolute smallest you should go for. 8’ by 10’ would be better.
If you want to add a cardio machine like a treadmill, you should look at an 8’ by 12’ shed.
Another consideration is the height. Sheds are usually not too tall and that can be a problem. Power racks and squat stands are usually the tallest equipment in a home gym. If you shop around you’ll be able to find this equipment that will fit your shed since there are taller and shorter models.
Try to find a shed that’s at least 6’ tall at the lowest point and preferably a bit higher. Most sheds have A-frame roofs so they are higher in the middle. That means you’ll be able to do pull ups and shoulder presses in the middle of the shed. Obviously if you’re taller than 6’, you should get a taller one.

Gym shed prices
So now we’ve got all of that out of the way, let’s look at what kind of prices you can expect.
The sheds we’re looking at are;
- 8’ by 8’
- 8’ by 10’
- 8’ by 12’
- At least 6’ high walls
I’ve divided the sheds into the different materials to make it a bit easier to see what you can expect for your chosen material. Of course the bigger the shed is, the more it’ll cost.
Of course this is for pre-fab sheds. If you’re going to DIY something the price can be different.
Metal shed prices
Metal sheds have the reputation to be relatively cheap. And that reputation is correct. They are by far the cheapest. Usually metal sheds are covered in vinyl so you won’t see any exposed metal.
Metal sheds in suitable sizes for a home gym cost anywhere from $500 to $2000. However, on average you can expect to pay about $750 for a small metal shed that’s still suitable for a home gym. For bigger metal sheds that can house cardio equipment and free weights, expect to pay about $1350.
Resin shed prices
Resin sits in between metal and wooden sheds price wise although they are closer to metal sheds than wooden ones.
Most plastic sheds are on the smaller side. For one that’s big enough to fit a gym into, expect to pay From $800 to about $1800. The smallest usable ones are around $1000 while the bigger ones go up from there.
Wooden shed prices
You can expect to pay significantly more for a wooden shed than metal or resin. Wood isn’t cheap; especially wood that has to last for a long time outside.
A pre-fab wooden shed will cost you at least about $2000 for a gym sized one. Expect to pay about $2500 for an 8’ x 8’ wooden shed on average. For bigger sizes you can pay up to $4000 although around $3300 is the average.

DIY Gym Sheds
Hiring a contractor to build a shed can be costly. If you’ve got the time to build it yourself, it can be a lot cheaper. However, many people don’t have the knowledge to build a good shed the first time round and will make some mistakes that could lead to a gym shed that isn’t very good, comfortable or usable.
