A double garage can become a brilliant home gym if you plan around real-world dimensions, ceiling height and clear training zones. We have created three popular double garage layout scenarios: Strength & Hyrox, Family Strength & Cardio, and Wellness with Infrared Sauna and Pilates reformer.
Most UK double garages range from roughly 5 m x 5 m up to about 6 m x 6 m, giving around 25–36 m² of usable floor space. Many newer builds sit at the smaller end (around 5.5 m x 6 m or 18 ft x 18 ft), while older or detached garages can be closer to 6 m x 6 m. A common "average" double garage size quoted is around 6 m wide x 6 m deep, which is ideal when you're converting purely to a gym rather than parking.
Ceiling height is just as important as floor area when you introduce strength training, overhead lifting and Hyrox movements. You ideally want at least 2.3–2.4 m clear height for overhead presses and wall balls, and more if you plan to hang a pull-up bar or rings above head height. Bear in mind that flooring build-up (rubber tiles, lifting platform, sled track) can "steal" 20–40 mm of height, so factor that into your layout planning.
Whatever layout you choose, think in terms of zones rather than random kit placement. In a 5.5–6 m wide double garage, you can comfortably run three primary zones from side to side:
Storage systems and wall-mounted solutions keep the floor clear and make each layout scenario feel bigger. Use vertical plate storage trees, wall ball racks, wall-mounted shelving, and possibly a single bay storage system for kettlebells, sandbags and accessories.
This layout treats the double garage as a hybrid strength and Hyrox training facility, ideal if you're prepping for races and want heavy lifting capability. Use 5.5–6 m x 6 m as the working footprint, with the garage door end acting as your "conditioning lane."
This scenario prioritises heavy compound lifting, race-specific conditioning and generous open floor space, so it suits serious Hyrox athletes or strength-biased functional fitness.
The family-friendly layout balances strength, cardio and general fitness so multiple people can safely train at once. It softens the space visually, gives clear "lanes" for traffic, and offers options for teens and adults to exercise together.
This arrangement is still strong on barbell work but deliberately reduces clutter, emphasises safety, and allows simultaneous use: one person lifting, one on cardio, another doing mat-based training.
The wellness-led layout turns your double garage into a boutique-style studio with space for relaxation, low-impact strength and recovery. It suits people who value Pilates, yoga, heat therapy and a calmer aesthetic, while still wanting some light strength training options.
This scenario dedicates more square footage to low-intensity, restorative work, while still leaving enough room for light resistance training and occasional higher-intensity intervals.
| Scenario | Approx. focus split (Strength/Cardio/Wellness) | Ideal double garage size | Best for |
|---|---|---|---|
| Strength & Hyrox | 50% / 40% / 10% | 5.5–6 m x 6 m | Hyrox prep, strong functional training. |
| Family Strength & Cardio | 40% / 40% / 20% | 5–6 m x 5.5–6 m | Mixed-ability households with kids. |
| Wellness, Sauna & Pilates Reformer | 25% / 25% / 50% | 5.5–6 m x 5.5–6 m | Low-impact training, recovery and de-stress. |
A few universal principles will make any of these layouts work harder for you.
With a thoughtful plan around dimensions, height and zoning, a standard UK double garage can comfortably become a dedicated strength and Hyrox facility, a versatile family gym, or a serene wellness studio with infrared sauna and Pilates reformer.
What are standard double garage dimensions for a UK gym conversion?
Typically 5.5–6 m wide x 6 m deep (25–36 m²), with 2.3 m+ ceilings best for lifts.
Can I fit a power rack in a double garage?
Yes, half/full racks fit along a 6 m wall; all-in-ones like REP Ares save depth (76–90 cm).
What's the benefit of a curved treadmill for Hyrox?
Self-powered, no motor noise/wear; mimics race running efficiently in 175 cm length.
How to make a family gym safe for children?
Cable machine or mulitgym , consider a smith machine, use light weights, suspension trainers, mirror's for form checks.
Does an IR sauna fit in a garage gym?
Yes, 1.2–1.5 m corner footprint; pair with reformer for wellness balance.
What flooring for double garage gyms?
Typically 15–20 mm rubber tiles over concrete; full coverage for drops/safety.
Power needs for multiple machines?
Double sockets along walls; cardio + trainers draw 2–3 kW total.
How to store accessories without clutter?
Wall-mounted racks, or vertical trees - some great multi product storage options available now.
