The Infrared Difference
Full-Spectrum Heat
The Arc range delivers near, mid, and far infrared wavelengths simultaneously. Each band interacts with the body at a different depth, providing a more complete therapeutic session than single-spectrum panels.
Deeper Penetration
Far infrared wavelengths penetrate tissue to a depth of 4–5 centimetres, reaching deep into muscle fibre, connective tissue, and joints — delivering therapeutic warmth that conventional air-heated saunas cannot replicate.
Lower Temperature
Infrared saunas operate at 45°C–65°C, considerably lower than traditional saunas. Because the body is heated directly, the lower ambient temperature does not reduce effectiveness — and many users find longer, more comfortable sessions are possible.
Faster Heat-Up
The Arc range reaches operating temperature in 15–20 minutes. Combined with the standard UK plug design, this makes infrared heat therapy genuinely practical for a daily wellness routine without planning or preparation.
Infrared Saunas for UK Homes
Infrared heat therapy has moved firmly into the mainstream of UK wellness culture, and for good reason. Unlike traditional saunas, which heat the air around you, infrared saunas use electromagnetic panels to warm the body directly — delivering therapeutic warmth that penetrates deeper into muscle tissue while keeping the ambient temperature at a comfortable, accessible level.
The Gravity Arc range was designed specifically for British homes: compact dimensions that fit a spare bedroom, home gym, or converted outbuilding; standard 13-amp plug operation that eliminates the need for specialist electrical installation; and a self-assembly system that two adults can complete in under two hours without specialist tools.
Every Arc cabinet is constructed from hand-selected Canadian hemlock — a timber chosen for its cellular density, low resin content, and natural resistance to the thermal cycling of regular sauna use. The result is a cabinet that looks premium, performs consistently, and will endure decades of daily use.
The Arc range spans three models: the single-person Arc One, the two-person Arc Duo, and the flagship four-person Arc Quartet — which is also suitable for sheltered outdoor installation. Each model features full-spectrum infrared panels, chromotherapy lighting, and a digital control system with pre-set programmes.
Whether you are investing in daily recovery support, chronic pain management, or simply a more considered approach to personal wellness, the Gravity Arc range offers a genuinely premium infrared sauna experience at a price point that reflects its construction quality.
