SA-CA-004 Concept Profile Pod
Cold-Climate Pod Sauna
A one-to-two-person pod with a rounded shell and a high-performance envelope, drawn to hold heat efficiently in the coldest regions from a small electric heater. The smallest, most thermally efficient profile in the archive.
- Capacity1–2
- HeatingElectric
- Heater class4.5–6 kW (electric)
- ClimateExtreme Cold, Cold, High Snow Load
Recommended use
Solo and couple use in extreme-cold climates and very small yards where fast, low-cost warm-up from a modest circuit is the priority.
Best suited for: Extreme-cold regions where efficiency is paramount · Solo bathers or couples · Very small or narrow yards

Design characteristics
- Small rounded shell that minimises surface area and interior volume for its seating
- Single L-bench for one reclined or two seated bathers
- Compact fixed window by the door for daylight without significant heat loss
- Low-slung curved roof that sheds snow and keeps ceiling volume tight
Construction notes
- Ribbed frame forming the curved shell over ground screws that lift the pod clear of snow
- High-performance insulation with a carefully taped vapour barrier at every seam
- Thermowood interior lining chosen for dimensional stability in hard freeze-thaw cycles
- Small sealed floor draining to a single point for quick drying
Heating profile
- The small, well-insulated volume suits a modest 4.5–6 kW electric heater
- Low stone capacity is appropriate for the compact room and fast warm-up
- Even in extreme cold, warm-up stays short because of the tight envelope
- A timer or app control lets the pod pre-heat quickly before a short session
Final heater selection must follow the heater manufacturer's sizing instructions, safety clearances and local electrical or fire-code requirements.
Advantages
- Lowest heat demand and fastest warm-up of the catalogued profiles
- Fits the smallest yards and tight side-yard spaces
- High-performance envelope excels in extreme cold
- Modest electrical requirement compared with larger rooms
Limitations
- Strictly one to two people
- Curved shell limits interior layout flexibility
- No room for a changing area or extended bench
- Specialised ribbed shell can be fussier to build than a flat-walled box
Common planning mistakes
- Oversizing the heater for such a small, efficient volume
- Compromising the continuous vapour barrier at the curved seams
- Forgetting that even a pod needs a planned cooling or robing spot nearby
The Cold-Climate Pod Sauna is the archive’s efficiency benchmark. Reading it against the larger cabins and the glazed cube shows how sharply interior volume, envelope performance and glazing drive heater size and warm-up time.

Frequently asked questions
How many people does the Cold-Climate Pod Sauna seat?
One to two, with the single L-bench drawn for one reclined bather or two seated.
Why such a small heater class?
The interior volume is small and the envelope is high-performance, so a 4.5–6 kW electric heater is typically sufficient. Confirm sizing with the heater manufacturer.
Is it really suited to extreme cold?
Yes. Its tight, high-performance envelope is why it is tagged for extreme-cold, cold and high-snow-load use, with short warm-up times.
What foundation is recommended?
Ground screws or a well-drained gravel base that keeps the pod lifted clear of snow and moisture.
Does it include a changing room?
No. At this size a cooling or robing area is planned separately, often just inside a nearby door or under a small covered spot.
This catalogue profile is intended for preliminary planning and comparison. Final dimensions, structural design, heater selection, electrical work and safety clearances must be confirmed by qualified professionals and the relevant manufacturer documentation.
