Equipping a commercial gym is a capital decision, not a shopping trip. The kit you choose determines your floor capacity, your staffing load, your maintenance bill and — through all of those — whether the site makes money. This guide covers how to specify a commercial fitness floor properly: what to buy, in what ratio, and which decisions are expensive to reverse.
Commercial specification is a different standard
The phrase “commercial grade” gets used loosely. In practice it means equipment engineered for continuous multi-user duty rather than a few hours a week: heavier frames, serviceable wear parts, upholstery rated for constant contact, and a warranty written for commercial use. Home-rated equipment placed on a paying gym floor tends to fail early, and the warranty usually will not cover it.
Three things separate a commercial specification from a domestic one:
- Duty cycle. Built for all-day use by users of widely differing size and skill.
- Serviceability. Wear parts — cables, bearings, pads, belts — can be replaced without replacing the machine.
- Warranty terms. Commercial use is explicitly covered, with defined parts and labour periods.
Plan the floor before you plan the purchase order
Work backwards from your expected peak occupancy rather than from your floor area. The questions that matter:
- How many members do you expect on the floor at your busiest hour?
- What is the split between strength, cardio and functional training in your membership?
- How much circulation space does your layout need to stay compliant and comfortable?
A floor that looks full on paper but queues at 6pm will cost you retention. A floor with duplicate stations in the right places will not.
A workable starting ratio
There is no universal formula, but this split is a sensible starting point for a general-population facility, to be adjusted once you know your membership:
| Zone | Share of floor | Typical contents |
|---|---|---|
| Cardio | 25–30% | Treadmills, exercise bikes, rowers, cross-trainers |
| Selectorised strength | 25–30% | Chest, back and leg machines |
| Free weights | 25–30% | Dumbbells, benches, racks and rigs |
| Functional / open | 10–20% | Turf, accessories, stretching space |
Beginner-heavy memberships justify more selectorised machines, because they are easier to use safely without supervision. Strength-focused and athletic memberships justify more rack and platform space.
The decisions that are expensive to reverse
Flooring
Specify it before anything is delivered. Retro-fitting proper gym flooring means clearing the floor you have just filled. Different zones want different thicknesses — a free-weight area takes impact a cardio deck never will.
Power and data
Cardio equipment needs sockets where the machines are going to live, not where the sockets happen to be. Agree the layout before first fix, and allow for the console connectivity your equipment uses.
Access and installation
Measure every door, lift and corner on the route from the loading bay to the floor. Large frames and rigs are the usual casualties here, and a machine that cannot physically reach the room is an expensive lesson.
Rig layout
A rig is usually bolted down and sized to the room. Changing your mind later is a structural job, not a reshuffle.
Total cost of ownership, not purchase price
The purchase price is the smaller number over an eight-year life. Build your comparison around:
- Parts availability. Can you source cables, pads and belts in a few days, or a few months?
- Serviceability. Can a technician work on it on site?
- Downtime cost. A single out-of-service station at peak hour is a member-experience problem, not just a repair bill.
- Upholstery and grips. The parts members touch wear fastest and shape how the gym feels.
A cheaper machine that is out of action for three weeks a year is not the cheaper machine.
Phasing a fit-out
If capital is staged, buy in this order. Each phase leaves you with a gym that works rather than a gym that is waiting.
- Flooring and fixed infrastructure. Everything else sits on it.
- Free weights and racks. Highest usage per square metre and lowest failure rate.
- Core selectorised range. The push, pull and leg stations your membership will queue for.
- Cardio. The most expensive per unit and the easiest to add in increments.
- Functional and accessories. Refine once you can see how members actually use the space.
Frequently asked questions
Can I use home equipment in a small studio?
If the studio is staffed and supervised with low concurrent use, some categories can work. But check the warranty wording first — most domestic warranties exclude commercial use outright, which leaves you carrying the whole replacement risk.
How many treadmills do I need?
It depends on your peak occupancy and membership profile rather than your floor size. Model your busiest hour, then specify to that, allowing for one unit out of service.
Should I buy a complete package or build the floor piece by piece?
Packages simplify procurement and delivery. Building piece by piece gives you a floor matched to your actual membership. For a first site, a core package plus a short list of considered additions is usually the better balance.
Do you help with layouts?
Yes. Send us your floor plan and expected membership and we will help you spec the room properly before anything is ordered.
