Take the tour
Ben walks through a Thermo-Aspen Cala Glass: the glass front and door, the benches, and how much headroom you get sitting up top. Then step inside one yourself in the 360° tour at the top of the page.
The wall elements are put together at Auroom’s factory in Estonia, so your build starts with finished panels. We’ve been to that factory.

Plan your space
Every Cala Glass is 59.8 in deep and 81.6 in tall at the front trim. Pick the length that fits your wall.
| Size | Outside | Inside | Upper bench |
|---|---|---|---|
| 59 × 59 | 59.1 × 59.8 in | 52.4 × 53.4 in | 52.4 in |
| 59 × 71 | 70.9 × 59.8 in | 64.3 × 53.7 in | 64.3 in |
| 59 × 79 | 78.7 × 59.8 in | 72.1 × 53.7 in | 72.1 in |
The two side walls are finished wood outside. The outside of the back wall is plain plywood, so set the back against a wall. Leave room for the door to swing out, and keep the top of the sauna reachable for your electrician.
Heat, power and sensors
Four things decide how well your Cala Glass heats and how smoothly the install goes. Here is how each one works on this sauna.
Glass loses heat faster than an insulated wall, so heater makers count it as extra room. HUUM adds 3.3 cu ft for every sq ft of glass. That puts the 59 × 71 and 59 × 79 in the range of the DROP 7.5 kW, the size we pair with them, and the 59 × 59 with the DROP 6 kW. For the Harvia KIP, the two larger sizes take the 8 kW.
Plan on about an hour of warm-up before you go in, so the walls are warm too.
The wood heater guard in the kit is made for the Harvia KIP. A HUUM DROP needs more room around it, so our DROP packages include HUUM’s own DROP Safety Rail: birch arcs on stainless supports that clamp to the heater.
Every heater lists its own clearances in its manual. Your installer follows that manual.
With HUUM UKU controls, the temperature sensor goes directly above the heater, on the wall 2 to 5 7/8 in below the ceiling. That wall has two factory pipes for the heater and control cables, right behind the heater, so the sensor cable has a route to the top of the sauna.
The door sensor is required. On the Cala’s glass door it goes low on the handle side, with its magnet on the door’s bottom corner, no more than 3/16 in away.
The heater needs its own 240 V hardwired circuit. The DROP 7.5 kW takes a 40 A breaker and #8 wire; the DROP 6 kW takes 30 A and #10. Each package lists its amps and wire size when you pick it.
The backrest light runs on 120 V. Connections are made in boxes on top of the sauna, so keep that space reachable or plan an accessible spot nearby.
The backrest LED comes with a wireless switch that needs no battery, and its own Wi-Fi dimmer app called Kinetic Switch. It is separate from the heater’s controls. Press the switch to turn the light on or off, and hold it to dim. After a power cut, the light stays off until you press the switch.
Your Cala Glass ships as one pallet by freight truck and is delivered to the curb. Moving it inside and building it are up to you.
| Size | Package | Weight |
|---|---|---|
| 59 × 59 | 91 × 46 × 38 in | 948 lb |
| 59 × 71 | 91 × 46 × 38 in | 1,213 lb |
| 59 × 79 | 91 × 46 × 44 in | 1,279 lb |
A 91 in package needs a plan. Have a pallet jack or a crew ready, and a clear path from the curb. You can unpack at the curb and carry the panels and glass in one at a time with a helper.
Steep drive, narrow street or stairs? Tell us before it ships and we’ll help you plan the unload. Freight and tax are added at checkout. An arrival date is for the warehouse, not a delivery date at your home.
For home use, your Cala Glass has a 2-year manufacturer warranty, subject to Auroom’s terms. Your heater has its own warranty. Auroom’s popular models and spare parts are stocked in the Chicago area.

Read the warranty ↗Good questions
For the simplest setup, pick a Harvia KIP: it fits the wood guard that comes with your sauna. The HUUM DROP holds 122 lb of stones for soft, steady steam, and its package includes HUUM’s DROP Safety Rail. On the 59 × 71 and 59 × 79, the Saunum Air Perfect blends the air for more even heat. Tell us how you like your sauna and we’ll help you pick.
Compare the packages ↑No. The sauna price covers the sauna. Add a heater package above, or buy the sauna on its own and add a suitable heater later.
The Harvia KIP. A HUUM DROP needs more room around it, so DROP packages come with HUUM’s DROP Safety Rail instead. Any other heater follows the clearances in its own manual.
With HUUM UKU controls, the temperature sensor goes on the heater wall, directly above the heater, 2 to 5 7/8 in below the ceiling. The wall’s two factory pipes for the heater and control cables run right behind the heater, so its cable has a route to the top of the sauna. The door sensor is required: it goes low on the handle side of the glass door, with its magnet on the door’s bottom corner.
A 240 V hardwired circuit for the heater, sized to the heater you pick, and 120 V for the backrest light. A licensed electrician makes the connections in boxes on top of the sauna.
No. The backrest light has its own wireless switch and its own Wi-Fi dimmer app, Kinetic Switch. Press the switch to turn it on or off, and hold it to dim. After a power cut, press the switch to bring the light back.
Plan on about an hour of warm-up before you go in, so the walls are warm too. The heater we recommend for each size counts the glass front.
It’s a prefab panel kit: the wall elements arrive assembled and screw together on site. Plan on two people for the panels and glass, and a licensed electrician for the heater, controls and light. Work from the manual for your exact size.
On a level, solid floor. The outside of the back wall is plain plywood, so set it against a wall. Leave room for the glass door to swing out, about 28 in, and keep the top of the sauna reachable for wiring.
Stop at that step and contact us before you build further. Send your order number, your sauna size, the manual page and clear photos of the parts. We’ll confirm the right instructions with Auroom.
Email our support team ↗The wall, floor and ceiling elements, the glass front and door, upper and lower benches, a backrest with LED light, floor grids, a wood heater guard for the Harvia KIP and a set of sauna accessories: bucket and ladle, thermometer, hygrometer, sand timer, aroma set, sauna hat and pillow. The heater, assembly and electrical work are separate.
The same sauna in two woods. Thermo-Aspen is thermally modified for a warm, deep tone; it takes up less moisture and moves less. Aspen is natural, light and smooth.
