Marriott 220 Outdoor Sauna (Black Stone) – 4 Person

Marriott 220 Outdoor Cabin Sauna — 4 person, Black Stone

The Marriott 220 is a traditional cabin-style outdoor sauna built for UK gardens. Peaked roof, vertical headroom, face-each-other interior benching — closer to a proper outbuilding than a wellness pod. 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 4 person layout fits two couples comfortably or four adults for shared garden 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 that blends with black-cladded garden rooms, dark fencing + slate-grey patios. The contrast with the warm interior wood when the door's open is the design payoff. Practical bonus: dark cladding hides UK winter dirt better than light finishes.

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: Outdoor saunas need a stable, level base ready before delivery (slabs on sub-base, concrete pad, or engineered deck).
• 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.
