Slate 220 Indoor Cabin Sauna — 6 person, White Stone The Slate 220 is a traditional cabin-style indoor sauna. Peaked roof, vertical headroom, face-each-other interior benching — a proper room-within-a-room rather than a wellness pod. Built for installation inside: a basement, garage conversion, utility room, home gym or dedicated wellness space. White Stone exterior keeps the design language consistent across the cabin range. Real Finnish heat: dry stones at 80–90°C, water thrown on for löyly, the proper bathing experience. The 6 person layout fits three couples comfortably or six adults for shared sessions. Running cost + warm-up (the question buyers ask first) Built around a 6kW–9kW electric stone heater (configured per build). Run cost at 30p/kWh is typically £1.75–£2.25 per 90-minute session. Warm-up takes around 30 minutes from cold to working temperature. White Stone finish — what it looks like over time The White Stone finish gives the cabin a bright, contemporary facade that reads as a finished room rather than a timber hut. The pale stone keeps the space feeling open and pairs easily with light-toned tiling and plaster. What's included Cabin, peaked roof, interior benches, glass door, instructions. Heater specification varies by configuration — confirm at checkout. Comes with UK warranty. Delivery & site preparation Standard delivery: Free standard delivery is included. Delivery type: Sauna deliveries are specialist freight or booked delivery — panel size + weight. Site preparation: This is an indoor sauna. It needs a level, load-bearing floor in a dry, ventilated room with adequate clearance around the heater. It is not weatherproofed and must not be sited outdoors. Access route: measure gates, turns, doorways from kerb to final position — cabin panels can be awkward through narrow access. Heater & electrical: Most 6kW–9kW sauna heaters need a dedicated 32A single-phase or 16A 3-phase supply. A qualified electrician must connect before first use. Installation: Assembly not included unless clearly stated on the product page or purchased separately.
