Slate 200 Indoor Sauna (White Stone) – 5 Person
Slate 220 Indoor Sauna (Black Stone) – 6 Person
Slate 220 Indoor Cabin Sauna — 6 person, Black 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. Black 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. Black Stone finish — what it looks like over time The Black Stone finish is the strongest visual statement in the range — matte dark cladding against warm interior timber. The contrast when the door is open is the design payoff, and the dark facade sits well against darker interior schemes. 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.
