Choosing a garden gym

Thinking practically is the key to choosing a garden gym room that offers an effective and enjoyable workout space. Here are a few tips:

  • Start by assessing available dimensions and choosing a size that will accommodate all your garden gym equipment comfortably, as well as give you space for warm up and warm down activities. 
  • Opt for durable and weather-resistant garden room materials that are able to withstand the elements.
  • Quality flooring offers stability and comfort during exercises. 
  • Overall, you’ll find that balancing functionality and aesthetics creates a garden gym that suits both fitness and relaxation.

Benefits of a garden gym

An insulated garden gym room is a great way to house your fitness equipment without taking up valuable space in your home. Investing in an insulated garden gym enhances your property's value while offering you a functional inside space in which to enjoy your workout. Compared to the expense of building a home extension, garden gyms present a budget-friendly solution. Designed with 'permitted development' rules in mind, our garden buildings enable you to expand your indoor space without the need for separate planning permission. For more information about planning requirements for garden buildings, check out our planning permission for garden buildings article.

What are the bet benefits of a garden gym?

Struggle to find the time and space to work out? Exercise is easier than ever with a personal gym in your back garden. Store bulky work-out equipment like cross-trainers and rowing machines in a garden room gym. The lockable door and double-glazed windows are strong deterrents for would-be thieves. 

Using an insulated garden room as a home gym gives you a comfortable place to work out all year round. High quality EcoQuilt multi-foil insulation in the walls, ceiling and floor help to keep you cool in summer and warm in winter. With more natural light and fresh air than a garage, a garden room gym also eliminates costly membership fees and lengthy commutes. 

A personal gym puts an end to queues for equipment or unwanted distractions. Your insulated garden room can also increase the value of your property, being an attractive feature for prospective buyers. And, in years to come, you can easily change your gym into a dedicated office, arts and crafts studio or a teenage games room. 

Delivered and professionally installed as part of the purchase price, choosing an insulated garden gym from Waltons is a no-brainer.

What size garden building is best for a gym? 

The size of the garden room you choose is dependent on the size of your garden and how much room you’d like to exercise in. Ranging from cosy 3x3m designs to show-stopping 6x4m options, there’s something for everyone in our collection of garden gym rooms. 

Think about what equipment you need to accommodate. All of our garden rooms are light and spacious, but consider getting a slightly larger model if you want a weight bench or extra storage to keep your resistance bands and pilates balls. 

How do you build a garden gym room? 

All Waltons insulated garden rooms come with free installation by our team of experts. After that, your garden room is a blank slate for you to turn into your perfect home gym. 

If you want to install lighting or a plug socket to charge a phone or speaker, consider connecting your shed to the mains electricity. You’ll need an experienced electrician to do this in a safe way, and comply with building regulations. 

Simple props or accessories can help your home gym feel like a proper work out space. Add a mirror wall for stretching, or a whiteboard to record those PBs! If you're a yogi, consider a raised bench to prop your laptop for online classes, with some plants and a speaker to help you get into a relaxed state of mind. 

Painted walls can make your home gym feel more personal. Thick rubber matting for the floor isn’t costly and is easier on the knees and sit bones. It also protects the floor from dents, especially if you’re going to be using heavy weights. Add hooks to hang up equipment, and storage squares for stashing away your outdoor shoes. 

What foundation is best for a garden room gym?

Choose either a paving slab or a concrete base as a foundation for your garden gym. A paving slab base is fairly easy to install yourself. A concrete base is the most permanent option but may require a builder to install if you’re not confident in your DIY abilities.


If you want to try your hand at building your own garden room base, use our step-by-step guide. Make sure your base is completely level to prevent the timbers of your new garden gym warping.

Can I get my new garden gym professionally installed?

Waltons insulated garden rooms are delivered and installed as part of the purchase price. Add a coloured wood treatment at the checkout to paint your exterior walls, protect the wood from decay and activate your 10 year anti-rot guarantee. To decorate the interior, take inspiration from the experts at Waltons blog and see what you can come up with!
