How to Set Up a Home Gym in Your Shed or Outhouse

Last updated: September 4, 2025

Why Choose a Shed for Your Home Gym?

A garden shed or outhouse makes an excellent home gym location for several reasons:

• Privacy: Work out without feeling self-conscious
• Convenience: No travel time to the gym
• Cost-effective: Save on expensive gym memberships
• Customizable: Design the space exactly how you want it
• No noise disturbance: Keep workout noise away from the house

Assessing Your Shed's Suitability

Before converting your shed into a gym, consider these essential factors:

Size and Space Requirements

The ideal shed gym should be at least 8x6 feet for basic equipment, but 12x8 feet or larger provides more flexibility. Consider the ceiling height too – you'll need at least 8 feet for exercises like overhead presses.

Structural Integrity

Ensure your shed can support the weight of gym equipment. A typical treadmill weighs 200-300 pounds, while a multi-gym station can weigh 400-500 pounds. Check the floor joists and foundation for stability.

Electrical Requirements

Most gym equipment requires electricity. Ensure your shed has proper wiring with sufficient outlets. Consider installing a dedicated circuit for your gym equipment to avoid overloading.

Ventilation and Climate Control

Proper ventilation is crucial for comfort and equipment longevity. Install windows, vents, or even a small air conditioning unit. In winter, you may need heating to make the space usable.

Essential Equipment for Your Shed Gym

Cardio Equipment

Cardio equipment is essential for a well-rounded fitness routine:

• Treadmills: Perfect for running and walking workouts year-round
• Rowing Machines: Full-body workout with minimal space requirements
• Exercise Bikes: Low-impact cardio option
• Ellipticals: Another low-impact choice that's easy on joints

Strength Training Equipment

Build muscle and strength with these essentials:

• Power Rack: Versatile for squats, bench presses, and pull-ups
• Adjustable Dumbbells: Space-saving option for various exercises
• Weight Bench: Essential for bench presses and other exercises
• Kettlebells: Great for functional training and saving space

Accessories and Extras

Don't forget these important additions:

• Exercise Mat: Essential for floor exercises and stretching
• Mirrors: Help with form and make the space feel larger
• Sound System: Music can motivate and energize your workouts
• Storage Solutions: Keep equipment organized and off the floor

Preparing Your Shed for the Conversion

Insulation and Climate Control

Proper insulation makes your shed gym comfortable year-round:

• Install fiberglass or foam board insulation in walls and ceiling
• Consider a small space heater for winter workouts
• Install a fan or air conditioning unit for summer
• Weather-strip doors and windows to prevent drafts

Flooring Solutions

The right flooring protects both your equipment and your joints:

• Rubber Gym Tiles: Easy to install, excellent shock absorption
• Interlocking Foam Mats: Budget-friendly and easy to replace
• Plywood with Rubber Mats: Sturdy option for heavy equipment

Lighting

Good lighting is essential for safety and motivation:

• Install bright overhead LED lights for general illumination
• Add task lighting for specific workout areas
• Consider natural light by enlarging windows or adding skylights
• Install dimmable lights for different workout moods

Layout and Organization

Zone Planning

Divide your shed gym into functional zones:

• Cardio Zone: Place treadmills and other cardio equipment near ventilation
• Strength Zone: Position power racks and weight benches in sturdy areas
• Flexibility Zone: Reserve space for stretching and floor exercises
• Storage Zone: Keep weights and accessories organized and accessible

Space-Saving Tips

Maximize your shed gym space with these strategies:

• Use wall-mounted storage for dumbbells and resistance bands
• Choose foldable or stackable equipment when possible
• Install ceiling-mounted storage for items used less frequently
• Use vertical space with wall racks and shelves

Safety Considerations

Structural Safety

• Have a professional assess your shed's ability to support equipment weight
• Ensure the foundation is level and stable
• Check for any signs of rot or pest damage before conversion
• Consider reinforcing the floor if adding heavy equipment

Electrical Safety

• Hire a licensed electrician for all wiring work
• Install GFCI outlets for protection against electrical shock
• Use surge protectors for expensive electronic equipment
• Keep electrical connections away from potential water sources

Fire Safety

• Install a smoke detector and fire extinguisher
• Keep flammable materials away from heat sources
• Ensure adequate ventilation for electrical equipment
• Have an emergency exit plan clearly marked
