Request Your Estimate 07367 086350From £8,995 · Delivered & installed Overview ## Jonas Grand Barrel Sauna, Teak. The Jonas Grand in teak-oiled thermowood is the traditional expression of a premium Nordic barrel, warm honey-toned exterior, panoramic glass end wall, twin-tier hemlock benches inside, and comfortable six-person capacity. The exterior is thermally-modified spruce finished with a Danish teak oil that saturates the surface, feeds the fibres, and gives the warm amber tone you see on old traditional saunas at Finnish lakesides. It's a finish that improves with age, not one that starts pristine and slowly disappoints. The same Harvia 9kW electric heater, the same knot-free hemlock interior, and the same 10-year structural warranty as the Ebony spec, the only meaningful difference is the exterior colour and the oil-refresh schedule. Key features ## What makes it different. ### 6-person twin-tier bench Upper and lower benches in solid hemlock. Fits six adults comfortably or four sprawled out. ### Teak-oiled thermowood exterior Thermally-modified spruce with saturating Danish teak oil, warm honey tone that ages beautifully. ### Harvia electric heater (9kW) Finnish-made Harvia heater with rock cradle, cool-touch guard and digital control. 25-minute warm-up. ### Panoramic glass wall Full-height toughened glass panel and door, turns the sauna into a lantern at night. ### Hemlock interior throughout Knot-free western hemlock benches, backrests, floor duckboards and wall lining. ### 10-year timber warranty Shou Sugi Ban and internal hemlock warranted 10 years against splitting or delamination.

Teak oil is a saturating finish, it soaks into the timber rather than sitting on the surface, so it can't peel. Owners who want to keep the honey tone re-oil every two seasons; those happy to let the timber silver leave it and let Scottish weather do its work. The barrel form heats fast for the same reason the ebony version does, compact air volume, curved ceiling that circulates heat evenly, and no cold corners to fight. Inside there is no visible difference from the ebony spec: same twin-tier hemlock benches, same Harvia heater, same glass front. The choice between ebony and teak is entirely about the look from the house. Best for ## Who typically buys this one. - Traditional and rural garden schemes - Buyers who want the classic Nordic barrel-sauna look - Larger families or entertainers wanting six-person capacity - Owners happy to re-oil every 2 seasons to preserve the tone On-site footage ## See it in motion. Still images only tell you so much. These short clips show the Jonas Grand Barrel Sauna, Teak exactly as it sits in a finished garden, the details a spec sheet can't convey. ### Jonas Grand Teak on-site The teak-finish Jonas Grand shown in a completed Central Scotland install. The video shows the roof line, cradle detailing and the full-length rear window, the details that separate a properly-specified barrel from an off-the-shelf import.

If your question isn't listed, call Ryan on 07367 086350. How is the Teak spec different from the Ebony?Only the exterior finish. Teak is thermally-modified spruce with a saturating teak oil (warm honey tone). Ebony is Shou Sugi Ban charred spruce (deep matte black). Everything else, heater, interior, glass, benches, warranty, is identical. How long does it take to heat up? Will the teak finish fade? Does it need 3-phase power? Can I have a wood-fired heater instead? How much space do I need? Do I need planning permission? What's the warranty? Next step ## Ready to talk about the Jonas Grand Barrel Sauna, Teak?
