For: Operators deciding whether to add, expand or remove recovery equipment, and the dealers who quote it.
The decision: Whether a recovery category earns the floor space it would take from training equipment, and what the building has to supply before the order is placed.
60-second answer: Measure both sides of the trade on your own floor: sessions per station by hour for the recovery unit and for the equipment it would displace, over the same weeks. Then read the specific model’s requirements, which differ widely: WellnessSpace lists its HydroMassage 340/350 bed at 500 pounds filled on a dedicated 208–240 V, 30 A line, while Hyperice lists Normatec Elite boots in three sizes on battery power. Saunas and steam rooms bring drainage and ADA section 612. Pilot one unit before building a room, time the cleaning and supervision it needs, and write the reclaim trigger into the approval.
What the space has to beat
The case for recovery equipment for gyms can rest on photographs. A floor plan needs a different input: how much use the space gets now, and how much a recovery unit would get instead. Throughput per square foot frames that trade well, provided both sides are measured on your floor rather than assumed. FEX takes no position on the physiological effects of any recovery modality; this guide covers space, building services and operating load only.
Records to pull:
- Sessions per station per hour for the equipment in the space now, from console data, booking records or manual counts taken at a fixed interval you choose.
- For an existing recovery unit: bookings or sign-in records by hour, repeat users against first-time users, and no-shows.
- The area each option occupies including access and circulation, from the manufacturer’s live-area or clearance figure where one is published, or measured on your plan.
- Cleaning logs, staff time on inductions and checks, and service tickets for any unit already installed.
Divide sessions by area for each option over the same weeks, including the hours when the floor is busiest. Early use of a new amenity can flatter it, so fix the observation period before you start. A category that loses the comparison can still be justified on membership positioning, but that argument should be made explicitly and priced, in a cash-flow case that does not invent retention gains.
What the specific model needs from the building
One unit’s specification says nothing reliable about its category. Examples as published by the manufacturers (accessed October 2026):
- Water massage bed. WellnessSpace lists the HydroMassage 340/350 bed at 91 by 39 by 26 inches, holding 30 gallons of distilled water and weighing 500 pounds when filled, and recommends 3/4 ton of air conditioning per unit. Its electrical requirements sheet calls for a dedicated 208–240 V, 30 A single-phase line with a NEMA L6-30R locking receptacle, plus a 110 V outlet for an external timer and maintenance, and a CAT-5 or CAT-6 network jack.
- Compression boots. Hyperice lists Normatec Elite legs with up to four hours of battery life and a 12 V wall charger, in Short, Standard and Tall sizes. A shared set needs a charging routine and enough units in each size for the members who book them.
- Cold plunge. Plunge’s product page for the All-In Gen 2 states that “this model is for residential use only.” The company sells a separate All-In Commercial Max for businesses; its product page lists ozone sanitation, an “NSF50 certified filter” and automated pH and chlorine adjustment. Plunge’s published circuit figures do not agree with one another, so take the circuit requirement from the unit’s nameplate and setup manual; Plunge’s support article on electrical requirements also says not to use an extension cord.
- Saunas and steam rooms. HFA’s best-practice guidelines (June 2022) call for a floor drain in saunas and a center or linear drain in steam rooms, and say commercial steam generators are three-phase, at 208/240 V or 480 V. Under the ADA Standards, saunas and steam rooms, where provided, must comply with section 612, which requires a turning space inside the room and, where seating is provided, at least one bench complying with section 903. Under the exception in section 241, where saunas or steam rooms are clustered at a single location, no more than 5 percent, but no fewer than one, of each type in each cluster must comply.
Weight matters above grade: a filled water bed or plunge tub is a concentrated load for the structural engineer, as covered in upper-floor load capacity. Dedicated circuits belong on the electrical schedule before drawings are issued, using the approach in cardio electrical requirements.
| Check | Evidence to get | Leans toward installing | Leans toward pilot, resize or decline |
|---|---|---|---|
| Displaced use | Sessions per station by hour for the equipment in the space now | Space measurably underused at the hours you staff | Current equipment busy at peak |
| Recovery demand | Bookings or counts from a pilot or an existing unit, with repeat users identified | Repeat use that holds through the observation period you set | Use concentrated in the first weeks or on tours |
| Electrical | The model’s electrical sheet and nameplate | Dedicated circuit and receptacle confirmed by your electrician | “Plugs into any outlet,” or an extension cord in the plan |
| Water and drainage | Fill, drain and water-treatment needs; floor drain location | Drain and water care in the plan, with a named owner | No drain; no water-care routine |
| Weight and cooling | Filled weight; the manufacturer’s cooling or ventilation guidance | Engineer and mechanical contractor have the figures | Filled weight unknown; room already warm |
| Commercial rating | Manufacturer statement of commercial use; warranty terms | Model sold and warranted for commercial use | Residential-only model |
| Cleaning and supervision | Timed cleaning per session; the manufacturer’s instructions for use | Fits normal floor cover at your quietest staffed hour | Needs a staff member the roster does not have |
| Accessibility | Accessible route; section 612 for saunas and steam rooms | Architect has confirmed the route and room requirements | Not reviewed |
Cleaning, supervision and screening load
Hygiene and supervision decide whether a category runs on normal floor cover. Sleeves, boots and upholstery need cleaning between users; wet areas need a scheduled regime regardless of use. HFA’s sauna guidelines, for example, call for users to sit or lie on towels and for the floor to be mopped daily. Time these tasks during the pilot rather than estimating them: log minutes per session for cleaning and per shift for checks, then multiply by the logged sessions at your own wage rates. Use the cleaning products and methods the manufacturer approves for each surface.
Where the manufacturer’s instructions for use list warnings, contraindications or a screening step, follow them, record that members received them, and train staff on what to do if a member feels unwell. Ask your insurer before installation which categories it treats differently. Booked access helps: it produces a usage record and gives staff a point at which to deliver the instructions.
Pilot, triggers and red flags
Pilot before building: place one unit in the space, run the same hourly log you use for the floor, and time the cleaning and supervision it consumes. A failed pilot costs a return; a failed room costs the fit-out. The structure for a trial is in new equipment pilots.
Triggers you set: before installation, write down what use, measured over what period, keeps the category, adds a second unit, or returns the space to training equipment, and who reviews it on which date.
Red flags:
- A business case built on tour photographs or survey intent, with no bookings or counts.
- A residential-rated unit quoted for a commercial floor.
- No dedicated circuit, drain or water-care routine in the plan.
- No reclaim date, so an underused corner stays in place by default.
What to do this week
- Log sessions per station by hour for the equipment in the proposed space, over a period you set.
- Get the electrical sheet, filled weight, drainage needs and cleaning instructions for the exact model being quoted.
- Confirm in writing that the model is sold and warranted for commercial use.
- Run a one-unit pilot with booking or sign-in records and timed cleaning.
- Write the keep, expand and reclaim triggers, with a review date, into the approval.

FEX editorial guidance: the evidence check, pilot structure and triggers are FEX analysis. FEX takes no position on the health effects of recovery modalities; this is not medical, electrical or legal advice. Manufacturer instructions control installation, cleaning and use. Confirm electrical, plumbing, structural and accessibility requirements with your electrician, engineer, architect and code official, and supervision and screening with your insurer.
