Ice bath and sauna recovery rooms for Kigali gyms

Start from the busiest half hour

Take your largest evening class or squad and assume everyone wants the water within thirty minutes. With about three minutes in the tub and two to change over, one plunge serves around a dozen people an hour — six in that half hour. Twenty people leaving a spin class therefore need three or four positions, not one.

The sauna is the easier half. A six-to-eight-seat cabin copes with a steady rotation, because people stay ten to fifteen minutes and leave in their own time. For a typical Kigali gym the numbers point to two or three tubs beside one compact sauna.

Padel, tennis and football clubs

Court sports book in blocks, so the demand arrives in pulses when a block of courts empties at once. A four-court padel club can send sixteen players to the tubs at the same moment; an extra tub and a smaller sauna serve that better than the reverse.

Football is squad-sized: twenty-five players finishing training together. That calls for a sunken plunge pool for six to eight or four separate tubs, with a coach setting the rotation. How clubs structure that rotation is explained in ice baths for athletes in Kigali.

Floors, drains and loads

Every exit from a tub drops water. We lay the zone to falls towards a channel drain, choose a slip-resistant finish that tolerates chlorine and ozone, and put a towel point between the water and the rest of the gym so nobody walks wet across the weights floor.

A 900-litre tub weighs close to a tonne before anyone climbs in. On a ground-floor slab that is trivial; on a mezzanine or an upper floor in Kimihurura it is a structural question, and we ask for the slab details before we quote.

Keeping shared water clean

Shared cold water needs circulation, a cartridge filter and an ozone or UV stage, plus a rinse shower at the entry so sweat and sunscreen stay out of the tub. A posted cleaning schedule and a simple water-test log, kept by one named person, make the difference between water that lasts weeks and water that turns in days.

Budget and running cost

A gym zone with two tubs and a sauna sits at 6.5 – 14 million RWF; a squad-sized club zone with four tubs, a rinse shower and filtration on every position is 15 – 32 million, both supplied and installed with duty and VAT inside. Chillers are the main running cost, and at 1,450 m they work less than they would in a hot lowland city. Commercial premises pay REG's non-residential rate of RWF 376 per kWh above the first 100 kWh a month (effective 1 October 2025, before VAT and the regulatory fee). The tubs themselves are described on the cold plunge page.

Key points

• About a dozen people per tub per hour — size from the busiest half hour, not the member list
• Channel drain, falls and a slip-resistant floor that tolerates chlorine
• Slab checked before quoting: a 900-litre tub is close to a tonne
• Circulation, cartridge filter, ozone or UV, and a rinse shower at the entry
