BS4000HG Outdoor Barrel Sauna
A four-person traditional barrel sauna in rustic Red Cedar, built for outdoor use and designed to earn its place in the garden. The half-glass front sets it apart — tinted glazing across the upper section lets light in and the view out, while the solid lower panel keeps things private at seated height. Three roof finishes let you match it to the space rather than the other way around.
Inside, the barrel format does what it does best: warmth circulates naturally around the curve. The 6kW hot-stone heater is included as standard, bringing the stones to temperature and holding them there. Ladle water across them and the humidity rises sharply — the löyly that defines a proper Finnish session. Higher-output heaters are available as a priced upgrade.
At 161cm, the interior benches are long enough to lie out on fully. Steel banding holds the staves true over time, and the timber skid base makes positioning straightforward. Delivered and installed by our own team, with a full handover before we leave.

Frequently asked questions
What's the difference between the three roof options?
Cedar shingles is the most traditional finish. The design roof (DESIGNDAK) is contemporary. Heather matting (HEIDEMATTEN) is naturalistic. All are structural equivalents — the choice is purely aesthetic.
Does my garden need preparation before installation?
A level, load-bearing base — concrete, paving slabs, or timber decking. Electrical supply also needs to be available. We confirm what's needed during the pre-installation assessment, included at no charge.*
Can the red light therapy upgrade be added after purchase?
It can be quoted separately, but we recommend including it at installation — fitted by the same team in the same visit, which is more cost-effective than a return trip.
