Description
The Pisara is the original Drop: a six-to-eight-person wood-fired outdoor hot tub, designed and made in Finland and named after the Finnish word for a drop. Its water-jacketed 35 kW Black Box stove heats the pool in around two hours, with the flames visible behind a glass door and the scent of firewood part of the experience; the stove body is made from durable aluminium and can be used with sea or lake water. The drop-shaped acrylic pool sits on a pressure-treated timber frame with 50 mm of polyurethane insulation, and the package includes the chimney with protective grill, hoses and clamps, an ash spade, an LED pool light, an insulated cover and a starter kit of water-care chemicals. There is no filtration system, so the pool is drained after each use through its outlet valve or with a submersible pump. It is available in White, Grey or Black. Delivery and installation are quoted individually, so please contact us for a tailored price.

Installation
The pool arrives upright and is turned by two to four people; allow around an hour for installation. It must stand on its frame on a level, load-bearing and horizontal base of concrete, gravel or timber able to carry 2,500 kg without sinking, with frost movement considered. The stove is delivered in parts and installed by the customer: it stands on a hard, level base at the same height as the pool, ideally within 1 m of the upper lead-in, connected with straight runs of the supplied 50 mm hose. The mouth of the chimney must be at least 3 m from flammable structures, and we recommend checking safety distances with your local authority. The stove must never be lit unless the water level is 5 cm above the upper lead-in and the stove is full of water. The installation and operating manual in the Downloads tab must be followed.
Care and winter use
Heat with dry firewood only and keep the insulated cover on while the water comes up to temperature. There is no filtration system, so empty the pool after each use, drain the stove through its base valve, rinse the hoses, and clear the firebox and ash pit once the embers have died down. In freezing weather the pool, stove and hoses must be emptied completely after use, with the drain plug and stove valve left open; frost damage is not covered by the warranty. The recommended bathing temperature is 37°C.
