The curved staves lock against each other and the steel bands hold them in compression, so the shell carries its own load round the curve without a frame. The Holvi 300 is the three metre model in the range: 46mm thermowood staves, stainless steel bands as standard, two double glazed windows, and the choice of a covered porch at the door end or a longer hot room without one.\u003c\/p\u003e\n\n\u003ch3\u003eWith or without the porch\u003c\/h3\u003e\n\u003cp\u003eThe same 3 metre barrel can be built two ways, and the choice changes how you use it.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith the porch.\u003c\/strong\u003e The first 60cm of the barrel becomes an open porch under the same roof, with a bench either side. That is where you cool down between rounds and keep towels and footwear dry, and it means the sauna door opens onto a sheltered space rather than straight into the weather. The hot room behind it is about 2.2 metres long inside, 8.24m³ of air.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWithout the porch.\u003c\/strong\u003e The door sits in the end wall and the hot room runs almost the full length of the barrel, about 2.7 metres inside and roughly 10m³. More bench length, more room to lie down, and a larger space to heat.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy the bands are stainless\u003c\/h3\u003e\n\u003cp\u003eA barrel only stays round and tight because the bands keep the staves pressed together. Timber shrinks each time the sauna is heated and dries out, then swells again through a wet British winter, so the bands work constantly and need checking and re-tightening over the life of the sauna. Ordinary steel bands eventually rust, and rust runs down the timber and stains it. Stainless steel does not. On most barrels stainless banding is an upgrade you pay extra for. On the Holvi it is standard.\u003c\/p\u003e\n\n\u003ch3\u003eWhat thermowood actually does\u003c\/h3\u003e\n\u003cp\u003eThermowood is timber that has been heat treated at around 200°C rather than chemically preserved. The process breaks down the sugars and resins that fungus feeds on and permanently reduces how much moisture the wood can reabsorb. The practical result outdoors is timber that moves less through wet British winters, resists rot without chemical treatment, and holds its shape in a structure that depends on staying perfectly round.\u003c\/p\u003e\n\u003cp\u003eA note on wall thickness: 46mm solid staves give the barrel plenty of thermal mass, but how warm a sauna stays is governed far more by the glass, the ventilation and the heater than by a few millimetres of timber. We would rather you chose the Holvi for the layout, the bands and the build than for a thickness figure.\u003c\/p\u003e\n\n\u003ch3\u003eAlso available with gas — no electrician, no chimney, no fire to tend\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePick a gas option at checkout\u003c\/strong\u003e and your barrel ships gas-ready: engineered ventilation built for gas, plus a bundled \u003cstrong\u003eFinSteam gas heater package\u003c\/strong\u003e — ready to light on a UK propane bottle the day it lands.
