Ridge & Ember

Saunas and cold plunges built for Rwandan hillsides

We design, build and service heat and cold rooms across Rwanda — from a two-person cabin on a Kimihurura balcony to a full thermal suite on the shore of Lake Kivu. Every cabin is drawn to your plot, because no two terraces in Kigali are the same slope.

Why it works in Rwanda

The altitude is the argument nobody here is making

Cold water is cheaper to hold here

A chiller fights the gap between target temperature and ambient. Kigali runs 26–28 °C by day and 16–17 °C at night, averaging 20.7 °C (Climates to Travel) — so the compressor cycles less than the same unit would at the coast, the bill is lower and the unit lasts longer.

Evenings are genuinely cool

At 1,450 m the evening drops far enough that a hot room is a pleasure rather than an endurance test, and it stays that way all year. Up at Kinigi, at 1,850–2,500 m, guests come off the volcanoes actively cold.

The market is arriving

Rwanda's tourism revenue hit USD 685 million in 2025 from 1.49 million visits, with MICE alone at USD 94.7 million across 165 events (Rwanda Development Board). Hotels and lodges are competing on amenity, and wet areas show up in reviews out of all proportion to their floor area.

Who we build for

How we work

A workshop in Gisozi, not a catalogue

Wall panels, benches, doors and plinth steelwork are cut and assembled in our Kigali joinery, then delivered as sections. You can come and put your hand on the timber before you choose it.

Only the hot-room timber and the equipment are imported. Basalt, brick, steel, glass and ironmongery are Rwandan — which shortens the lead time and takes the finished-goods duty band out of the price.

Every quote shows the heater calculation, the access plan and the service run as separate lines. If the slope or the cable is what makes your project expensive, you will see it.

How a project runs

Four stages, one payment schedule

  1. Site visit

    We come with a laser measure and a camera. Slope, access route, distance to the board, where the plant can live and whether the neighbours will hear it.

  2. Drawing and quote

    A dimensioned drawing, the heater calculation, the material choice and a price with access and services split out. Indicative, then fixed once the drawing is signed.

  3. Build and deliver

    Panels made in Gisozi while the wet trades and the electrical run happen on site. Assembly is days, not weeks, because the cutting already happened.

  4. Handover and service

    Commissioning, a walk-through, the operating notes, and a service visit booked — six months for commercial rooms, twelve for homes.

40% to start the drawing and order materials, 40% when panels leave the workshop, 20% on commissioning.

Questions

Asked before every project

Do you build outside Kigali?

Yes — Rubavu and Karongi on Lake Kivu, Musanze and Kinigi for the volcano lodges, Nyungwe, Akagera, Huye. Upcountry work is scheduled in blocks so the travel cost is shared between sites in the same week.

How long does a sauna take from order to first session?

Six to ten weeks for a standard cabin once the drawing is signed, and three to four if we already have the section in stock. The long pole is imported timber: 35–42 days at sea plus 5–10 days overland from Mombasa or Dar es Salaam (Sino Shipping).

Can you work with our architect?

Gladly, and the earlier the better. The three things we need in the build drawing are a drain with a fall, a mechanical extract route and a cable run to the board. Everything after that is finishes.

Do you service equipment you did not install?

Yes, if parts are obtainable. Roughly half our service calls are for somebody else's installation.

What does it cost to run?

A 9 kW heater pulls full load for the twenty to forty minute heat-up, then cycles at a third to a half of nameplate — an evening is closer to 4–6 kWh than to 9. A chiller in Kigali runs less than the same unit would at the coast because the nights are cool.

Is there a warranty?

Two years on our build and workmanship, and the manufacturer's terms on heaters, generators and chillers, which we register for you. Service visits keep both valid.

Can a sauna be moved when a lease ends?

Yes — we build a demountable specification with a bolted frame and a single service connection point. It is the standard in Kacyiru, where most housing is on corporate leases.

Which languages do you work in?

English and Kinyarwanda. Drawings, quotes and the operating manual come in whichever you prefer.
