A hotel gym that works starts at 25-30 sqm of usable space and rises to 40-60 sqm in properties with 40 to 80 rooms, with a clear height of at least 250 cm. The provision that covers almost every request fits into four cardio machines, a rack of dumbbells from 1 to 20 kg, an adjustable bench, and 8-10 sqm of clear floor. Yet plenty of gyms set up exactly this way stay empty for entire seasons. The answer isn’t in the machines, and we’ll get there step by step.

How many guests actually use the gym at the same time
The first figure you need is concurrency, and it surprises almost everyone. In a property with 40-80 rooms, the number of people present at the same moment is two to four, concentrated between seven and nine in the morning and between six and eight in the evening. There are no gym members and nobody comes to train for two hours, so you don’t need six treadmills: you need one or two that always work, in a room that’s actually pleasant to be in.
How many square metres are needed for each type of property
| Property | Floor area | Realistic provision |
|---|---|---|
| B&B and hotels up to 15 rooms | 15-20 sqm | one cardio machine, dumbbells, mats, mirror |
| Hotels with 20-40 rooms | 25-40 sqm | two or three cardio machines, dumbbells up to 15 kg, one bench |
| Hotels with 40-80 rooms | 40-60 sqm | three or four cardio machines, dumbbells up to 24 kg, two benches |
| Over 80 rooms and resorts | 70-120 sqm | five to eight cardio machines, separate weights area, functional zone |
Below 20 sqm you can put together a decent fitness corner and describe it as such; calling it a gym on the website leads to disappointment the moment the first guest opens the door.
Ceiling height deserves a separate check, because nobody verifies it and it can’t be fixed afterwards. A treadmill lifts the user 15-20 cm off the floor: with a 240 cm ceiling, a 190 cm tall person running will touch it. Below 250 cm the room can’t take cardio equipment, and 270 is the comfortable figure.
Safety clearances and the footprint of cardio machines
The most overlooked constraint is the clear space behind a treadmill. Anyone who loses their balance gets thrown backwards by the belt, so you need at least 100 cm free, with no furniture, no mirrors and no wall. With a footprint of 200 x 90 cm plus side access, a single treadmill needs a real 3-3.5 sqm.
Other footprints, including manoeuvring space: exercise bike or recumbent bike 1.5-2 sqm, elliptical 2-2.5 sqm, rowing machine 1.8-2 sqm in use and then stored vertically against the wall, bench with dumbbell rack 200 x 200 cm. Between zones, leave 90-100 cm of clearance. The bodyweight training zone needs 6-8 sqm, that is, a rectangle of 250 x 300 cm, and it’s the one that gets cut first when the numbers don’t add up. That’s a mistake: it’s where stretching and cool-down happen, the most frequent activities among guests who don’t train regularly.
Gym layout: where to place machines, weights and open floor
The most common layout mistake is putting the machines in the middle of the room and the open space against the walls. It works the other way round. Cardio machines should line up along the wall with the view or the window, because that’s where people stay still looking straight ahead for twenty minutes, with 30-40 cm clear between units and the back of the treadmills facing the open space.
Free weights go on the opposite side, against a structural wall rather than plasterboard, with the dumbbell rack fixed or weighted down: a rack loaded with 60-80 kg tips over when someone sets the last piece down badly on the top shelf.
The middle stays open, with the mats.
Technical flooring and vibration isolation
Technical flooring protects the slab, dampens vibration and provides grip. Getting it wrong produces complaints from the rooms below within the first week.
In the cardio zone, use recycled SBR rubber or virgin EPDM rubber, 8-10 mm; in the weights zone, go up to 15-20 mm, because that’s where dumbbells get dropped. Sports PVC at 4-7 mm is fine for the bodyweight zone only. Carpet has no place in a gym, because it holds sweat and can’t be washed.
Two conditions decide whether the installation works. Under the rubber you need a flat, dry screed, otherwise bumps turn into vibration under the mat. Under every cardio machine you should add a 10-15 mm anti-vibration pad with perimeter decoupling, and if the gym sits above a room, that’s effectively mandatory. The solution that solves the problem at its root is placing the room in the basement or above a plant room.
Mirrors in the gym: safety and fixing
A mirror doubles the perceived size of the room and is also the most dangerous element in it, because it sits next to people handling cast iron.
It should be laminated or tempered glass, or have a safety film on the back that holds fragments together. Fixing must be mechanical, with profiles or plates: structural adhesive alone fails under humidity and constant vibration. The bottom edge should be raised 15-30 cm off the floor with a kick plate, because the foot of a mirror is where badly set-down dumbbells end up. At the top, it goes up to 200-210 cm. No mirror in the fall zone behind a treadmill, and none on the wall where a squat is racked. Hotel mirrors intended for a gym are a different product from those used in rooms.
The same applies to everything wall-mounted: racks, TVs, bodyweight exercise bars. The fixing depends on the actual wall structure, which needs checking with a drill before deciding, and plasterboard requires a pre-fitted structural reinforcement. A pull-up bar fixed to plasterboard alone fails with someone hanging from it. Installation with internal brackets is the point at which this check needs to happen and be recorded.
Lockers, bench and storage for people training
Guests arrive in kit, with their room card, phone, a small bottle and a towel, and no pockets. This drives the furniture provision, which accounts for less than 15% of the budget.
You need six to twelve day lockers of around 30 x 35 x 35 cm, in compact HPL or laminate on a moisture-resistant substrate because the environment is humid, with a code lock if the gym is unstaffed. You need a backless bench, seat height 42-45 cm and 100-140 cm long, with a rigid top, for changing shoes. You need sturdy hooks every 15-20 cm, properly wall-plugged, because adhesive ones won’t hold a wet bathrobe. You need a shelf at 90-100 cm next to the door. And you need a closed cabinet for mats, exercise balls and resistance bands, with shelves at 40 cm intervals, otherwise the kit ends up piled in a corner. Built to measure and flush to the wall, this falls under common area furnishings and coordinates with the rest of the property.
Then there are the items costing a few hundred euros in total that matter more than the machines: a towel stand with separate clean and used compartments, a disinfectant dispenser with a paper roll, a pedal bin, a clock with a second hand, a water point away from the equipment.
Ventilation, temperature and air exchange
Here’s the real answer. A gym generates heat, humidity and odour in a small volume, and without dedicated air exchange it becomes unusable within twenty minutes. Not the return air from the breakfast room: its own system, with a flow rate calculated by the installer at values well above those of an office of the same size.
The working temperature should sit between 18 and 20 degrees, with relative humidity between 40 and 60%. A room kept at 24 degrees, the comfort temperature for common areas, is physically unusable for anyone running, and a thermostat set to the same value as the rest of the hotel is the number one cause of empty gyms. A ceiling fan costs little and changes a lot.
All surfaces should be washable, with daily disinfection of handles, seats and dumbbells, assigned in writing the same way it is for rooms.
Gym lighting: lux levels and colour temperature
A gym isn’t about atmosphere: it’s about being able to see. You need 300-500 lux at floor level, evenly distributed, colour temperature 4000 K, colour rendering above 80, because the warm light used in bedrooms creates a tired-looking space here. No light fitting directly above a treadmill or above the mat area, where anyone stretching looks upwards, and no direct reflections in the mirrors, which should be checked at design stage.
Access and safety with an unstaffed reception
Almost no hotel staffs its gym, and this raises a question of liability that needs to be managed through organisation. An electronic lock opened with the room card limits access and logs who enters. Time slots, typically from 6.30am to 10pm with night-time closure, are preferable to round-the-clock access. Rules posted in Italian and English should state the ban on unaccompanied minors, the advice to stop in case of feeling unwell, and the requirement for shoes and a towel, with instructions for each machine posted on the wall using pictograms.
The element most often missing, and the one that matters most, is a call button connected to reception, or at least an internal phone in the room: where someone might be training alone at six in the morning, that’s the minimum level of cover. Glazing towards the corridor or the pool adds informal supervision and shows the service to other guests.
Why hotel gyms stay empty
Hotel gyms rarely stay empty because of the machines. They stay empty because the air is still and the thermostat is set to 24 degrees, because there’s nowhere to put down a card and a bottle, because there’s no towel or disinfectant, because the light is warm and the room looks like a storeroom with a treadmill in it. These are items that cost a fraction of the equipment and decide whether the space actually gets used. Anyone weighing up a project can ask for a quote for the fitness area, separating furniture and equipment from the outset, since they come from different suppliers on different timelines.
Frequently asked questions about furnishing a hotel gym
How many square metres does a hotel gym need?
From 25-30 sqm for a basic functional gym, 40-60 sqm for a property with 40-80 rooms, 70-120 sqm for resorts. Below 20 sqm you can only fit out a fitness corner with one cardio machine, dumbbells and mats. Clear ceiling height needs to be at least 250 cm, better 270 if a treadmill is planned.
How much space is needed behind a treadmill?
At least 100 cm completely clear, with no furniture, mirrors or walls, because anyone who loses their balance gets thrown backwards by the belt. Adding the 200 x 90 cm footprint plus side access, a single treadmill takes up a real 3-3.5 sqm. It’s the constraint most often ignored, and it can’t be fixed after installation.
What flooring should go in a hotel gym?
Recycled SBR rubber or virgin EPDM rubber, 8-10 mm in the cardio zone, 15-20 mm where weights are dropped, laid on a flat, dry screed. Under every cardio machine, add a 10-15 mm anti-vibration pad. Carpet is ruled out because it holds sweat and moisture and can’t be washed.
Can I put the gym above the bedrooms?
Yes, with a full anti-vibration package under the machines and perimeter decoupling, otherwise complaints arrive within the first week. The solution that removes the problem entirely is the basement or a plant room below. If the position is fixed, it’s worth giving up on the treadmill and sticking to a bike and an elliptical.
What temperature should it be kept at?
Between 18 and 20 degrees, with relative humidity between 40 and 60% and dedicated mechanical air exchange. A room set to 24 degrees like the common areas becomes unbearable after a few minutes of activity. It’s the most common management mistake, and it’s fixed by excluding the gym from the general thermostat setting, at no cost at all.
How do I manage access if reception isn’t staffed?
An electronic lock opened with the room card, time slots with night-time closure, rules posted in two languages, instructions on each machine, and a call button connected to reception. Where regulations allow it and with a notice displayed, CCTV adds a layer of protection against misuse of the equipment.
How much does the furniture cost, excluding equipment?
Day lockers or cube storage, bench, coat hooks, a made-to-measure kit cupboard, mirrors with mechanical fixing, towel stand and dispensers cost roughly 3,000 to 12,000 euros depending on size and finish. Cardio machines, weights and technical flooring are separate items and absorb most of the investment.
