Overview
M1 is the assembled sauna. Its architecture stays fixed while extensions are selected for the site.
Black exterior timber, natural sauna-grade interior, panoramic safety glass, steel base, and dark roof build-up.
Access, transition, baseline heat, water, storage, and cold immersion are added where the site supports them.
Foundation, delivery path, services, exposure, permits, and placement are reviewed before order.
What is included with SAUNA. and what remains site-specific is made clear before order.

03 — Selected extensions
M1 is the fixed product. M2–M7 extend it with access, transition, baseline heat, rinsing, storage, cold immersion, and return where the site allows.
M2 extends the fixed core where a water-access connection is required.
M3 adds a defined transition between the site and sauna cabin.
M4 is the optional pre-warm layer. When included, it can support baseline readiness, remote pre-heat, changing-room comfort, or another site-specific heat need. M4 creates a warmer starting condition; it does not heat the sauna to bathing temperature. The sauna stove completes the lift and remains the bathing heater.
M5 and M7 add water-dependent functions where supply, drainage, and site conditions allow.
M6 adds nearby storage to the selected arrangement.
04 — Site requirements
Prepared concrete slab or screw piles
Vehicle delivery path; crane where direct placement is not possible
Active sauna stove load, plus M4 load where included
Optional; required where selected M5/M7 functions depend on plumbing
Municipality-dependent and confirmed for the site
Reviewed for access, weather, view, and services
05 — Included / not included
06 — Delivery and placement
SAUNA. M1 is delivered as an assembled sauna unit. The delivery path, placement method, lifting requirement, site readiness, electrical connection, selected extensions, and local responsibilities are confirmed before order.
Where direct placement is possible, the unit is placed from the delivery path. Where access is limited, crane placement or special handling is reviewed.
