Description
The Drop S is a six-to-eight-person outdoor hot tub that pairs the minimalist, drop-shaped form of the original Drop with modern spa technology, designed and made in Finland by Drop Design Spa. Four moulded massage seats are fed by six massage nozzles and a dedicated 1.1 kW massage pump, designed to deliver a measured, relaxing flow of water. The acrylic pool sits over an insulated aluminium frame and can stand freely or be embedded into a terrace, and every spa includes 3 kW electric heating, a filtration and UV system, LED lighting, a digital control panel, an insulated cover and a starter kit of water-care chemicals for year-round use. It is available in White, Grey or Black. Connection must be carried out by a qualified electrician to a three-phase 400 V supply as standard; please ask us about single-phase options before ordering. Delivery and installation are quoted individually, so please contact us for a tailored price.

Installation
The spa arrives upright and is turned and positioned by four to six people; grooves for lifting straps are moulded into the base. It must stand on its frame on a level, load-bearing and horizontal base of concrete, compacted stone or timber able to carry 2,500 kg without sinking, with frost movement considered and at least 50 cm of service access on all sides; a spa sunk into a terrace needs a service hatch so the side panels can still be opened. Connection may only be carried out by a licensed electrician, the supply must be RCD protected, and power must not be switched on until the spa is filled with water. The supply cable can enter through any corner of the cladding or a lifting-strap groove, and other electrical devices must be kept at least 2.5 m from the spa. The installation and operating manual in the Downloads tab must be followed.
Using the spa
The water temperature is set from the control panel, between 10°C and 40°C with 37°C the recommended bathing temperature. Keep the pH between 7.0 and 7.4 and add chlorine or an equivalent treatment after bathing, or at least once a week; the filtration and UV system keeps the water clear day to day but does not replace chemicals. Replace the water two to three times a year depending on use, rinse the filter under running water a few times a month, and keep the insulated cover closed and locked whenever the spa is not in use. The spa is designed to stay filled and running through winter; only a power cut lasting several days puts it at risk of freezing, and frost damage to a spa emptied for winter is not covered by the warranty. The pool is emptied with a submersible drainage pump (not a metal one).
