Specification-based research shortlist—not a hands-on test, price ranking or exact-model customer-review ranking. A listed capacity does not establish comfortable seating. Each product page separates seller statements, source contradictions and owner-evidence gaps.

Research pick: SunSwell 4–6 Person Barrel

A panoramic barrel (the listing contradicts itself on exterior size) with a 6 kW heater, stones and roof tarp, on a 220V supply. Confirm bench lengths before relying on the advertised six-person capacity. We have not verified current prices, so this is not a price ranking.

Compact pick: Royal Saunas vertical cedar barrel

An upright 63 × 63 in cedar barrel with a 6 kW Harvia heater; stones sold separately. Confirm the bench plan before relying on the four-person capacity.

Before you buy

Both list high-voltage electric heaters; the exact manual and a licensed electrician must establish circuit suitability. Budget from site-specific quotes for power, a level base and delivery.

Footprint excludes installation allowances. Interior volume per advertised seat is not usable bench space; heater kW alone does not establish performance.
