The stove heats the water directly, convection circulates it, and you control the temperature by how much wood you burn and when you stop feeding it.\u003c\/p\u003e\n\n\u003cp\u003eThe stove is \u003cstrong\u003eintegrated into the tub wall\u003c\/strong\u003e, keeping the footprint to a single circle rather than a tub plus a separate heater.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHeat-up time is the honest trade-off.\u003c\/strong\u003e Expect roughly 3 to 4 hours from cold with a well-fed fire. That is slower than an electric spa you leave running at temperature — but you are not paying to keep 1650 litres hot 24 hours a day for the two evenings a week you use it.\u003c\/p\u003e\n\n\u003ch3\u003eRunning cost, honestly\u003c\/h3\u003e\n\n\u003cp\u003eAn electric hot tub costs roughly £40–£80 a month to keep at temperature year-round, whether you use it or not. A wood-fired tub costs \u003cstrong\u003ewhatever the wood costs\u003c\/strong\u003e — typically a few pounds per session — and nothing at all when it is sitting idle.\u003c\/p\u003e\n\n\u003cp\u003eThe catch: you light it each time. If you want to step into hot water on a whim at 9pm, an electric spa does that and this does not. If you plan your soak an hour or two ahead, this is far cheaper to own.\u003c\/p\u003e\n\n\u003ch3\u003eNo electrics, no electrician\u003c\/h3\u003e\n\n\u003cp\u003eThis is the part that decides it for a lot of gardens. A conventional hot tub needs a dedicated supply — commonly \u003cstrong\u003e£400–£1,200\u003c\/strong\u003e for a garden circuit, plus Part P notification. A wood-fired tub needs none of it. No cable, no trench, no consumer-unit work.\u003c\/p\u003e\n\n\u003cp\u003eThat makes it possible at the bottom of a garden, on a plot with no supply, or anywhere running power would cost more than the tub.\u003c\/p\u003e\n\n\u003ch3\u003eSmoke and neighbours — read this first\u003c\/h3\u003e\n\n\u003cp\u003eA wood-fired tub has a flue and produces smoke, and we would rather flag that now than have you discover it later.\u003c\/p\u003e\n\n\u003cp\u003eIf you are in a \u003cstrong\u003esmoke control area\u003c\/strong\u003e, the rules apply to garden appliances with a chimney. You may only burn authorised fuel unless the appliance is on DEFRA's exempt register. Check your postcode with your council before ordering — our \u003ca href=\"\/blogs\/news\/sauna-in-smoke-control-area\"\u003esmoke control area guide\u003c\/a\u003e covers what that means in practice.\u003c\/p\u003e\n\n\u003cp\u003eEven outside a smoke control area, think about where the smoke goes. A flue close to a neighbour's windows causes friction regardless of what the law permits.\u003c\/p\u003e\n\n\u003ch3\u003eWater care\u003c\/h3\u003e\n\n\u003cp\u003eWithout a filtration system you change the water rather than treat it continuously. For a tub used a couple of times a week, that means emptying and refilling every week or two — cheaper and simpler than dosing chemicals, but it is a job.\u003c\/p\u003e\n\n\u003cp\u003eChemical treatment is possible if you would rather leave the water in longer. We can advise on what suits your usage.\u003c\/p\u003e\n\n\u003ch3\u003eSiting it\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eA firm, level base.\u003c\/strong\u003e At 250 kg empty and around 1,900 kg full, this needs a concrete pad. Standard garden decking will not carry it. Water alone weighs a tonne per cubic metre. Paving slabs on a compacted sub-base, a concrete pad, or a deck rated for the load — and check the deck rating properly, because most garden decking is not built for this.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eClearance around the stove and flue.\u003c\/strong\u003e The firebox and chimney get genuinely hot. Keep them clear of fencing, overhanging branches and anything combustible.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDrainage.\u003c\/strong\u003e You will empty it regularly, so think about where the water goes.\u003c\/p\u003e\n\n\u003ch3\u003eHot and cold together\u003c\/h3\u003e\n\n\u003cp\u003eA wood-fired tub next to a sauna or a cold plunge is the traditional Nordic pattern, and each gets used far more when they are together.
