BS4000LHG Barrel Sauna
Heating system: Traditional hot stone
The longest barrel in the range — 230cm of rustic Red Cedar, built for four people and designed around one key distinction: at 177cm, the interior bench is long enough to lie flat. If you use a sauna to genuinely stretch out rather than sit upright, this is the model to choose.
Like all traditional Finnish-style saunas, the BS4000LHG heats by hot stone convection, not infrared. The included 6kW heater brings the stones to temperature; the barrel form circulates heat naturally, with no corners for it to stall in. Ladle water over the stones to release a sharp burst of steam — the Finnish practice of löyly — and the experience is immediately, unmistakably different from anything a panel-based sauna can offer.
The half-glass upper panel gives you light and a view from inside — the garden, the sky, whatever is there — while the solid lower panel keeps everything private at seated height. Steel banding and a timber skid base. Red light therapy can be added for £999, installed at the same time as the sauna by the same team.

Frequently asked questions
What makes the LHG longer than the standard HG?
The LHG adds length to the barrel — 230cm exterior versus the HG's shorter barrel — which translates directly to the 177cm interior bench. The heater, glazing and roof options are the same; the difference is entirely about interior space and the ability to lie flat.
How do I prepare my garden for this?
You need a level, firm base — concrete, paving or quality decking — and a suitable electrical supply nearby. We confirm exactly what your site needs during the pre-installation assessment, included at no charge.*
What is löyly and can I do it in this sauna?
Löyly is the Finnish practice of ladling water over hot stones to release a sharp burst of steam. Yes — the BS4000LHG is fully löyly-capable. It is what distinguishes traditional Finnish heat from infrared and is one of the main reasons people choose this format.
