Request Your Estimate 07367 086350From £6,495 · Delivered & installed Overview ## Jonas S Barrel Sauna, Ebony. The Jonas S is the Grand's compact sibling, 1.9m long, four-person capacity, and the same properly-executed Shou Sugi Ban ebony exterior. It's the barrel we install into gardens where the Grand's 2.4m footprint feels indulgent. Because the internal volume is smaller, the same Harvia heater brings it to soaking temperature in around 20 minutes, five minutes quicker than the Grand and noticeably cheaper to run over a year. The interior is identical to the Grand: knot-free western hemlock throughout, twin-tier benches, glass door, backrests. The only compromise you make choosing an S over a Grand is capacity, build quality, materials and finish are the same. Key features ## What makes it different. ### 4-person capacity Twin-tier hemlock benches, four adults or two adults plus three kids in real comfort. ### Shou Sugi Ban ebony exterior Same genuine charred-and-oiled spruce as the Grand. Deep matte black that ages to graphite. ### 6kW Harvia heater Sized to the smaller air volume, 20-minute warm-up, lower running cost than the Grand. ### Glass door, hemlock interior Toughened glass door and knot-free western hemlock lining, benches and duckboards. ### Fits smaller gardens 1.9m x 2.0m footprint, clears most standard 900mm side gates on a two-person carry. ### 10-year timber warranty Same 10-year structural warranty as the Grand. Built in the same Falkirk workshop. Specification ## The numbers behind the object.

Four adults is the honest capacity. Owners regularly fit a fifth person on the lower bench, but the twin-tier design is optimised for four with room to lie down on the upper bench for a proper sweat. The 6kW heater is important. Installers who spec a 9kW Grand-sized heater into an S-sized barrel end up with a sauna that hits 100°C in 12 minutes then trips the safety cut-out. Ours is sized for the air volume. Because it's lighter (~560 kg empty) it's easier to place on a properly-prepared deck rather than needing a concrete pad, subject to survey of the deck substructure. Best for ## Who typically buys this one. - Urban and suburban gardens with restricted space - Couples and families of 2–4 - Buyers who use the sauna daily and value quicker heat-up + lower running cost - Gardens where an S can fit through the side gate but a Grand can't Real installations ## Jonas S in Scottish gardens. Every photograph on this page is a genuine Signature Garden Rooms installation. Frequently asked ## Straight answers. If your question isn't listed, call Ryan on 07367 086350. How is the S different from the Grand?Same build quality and finish; smaller size. The S is 1.9m x 2.0m (vs 2.4m x 2.2m), seats 4 (vs 6), heats in ~20 minutes (vs 25), and uses a right-sized 6kW heater instead of 9kW. Will it fit through my side gate? Is the ebony finish paint? Can I have it in the teak finish? What power supply do I need? Can it sit on a timber deck? How long is the warranty? What's the lead time?
