Black Pearl 1, ∅ 2,2m hot tub with integrated wood-burning heater for 6-8 people. Thermal cover included!

Black Pearl 1 – Your private spa, reimagined.

Crafted with care and built to last, Black Pearl 1 offers the ultimate blend of relaxation and functionality. This larger version of our most popular round hot tub provides comfortable seating for 6 to 8 adults and features a 30 kW integrated wood-burning heater made from high-quality stainless steel (AISI 304).

At its heart is a durable, marine-grade Gelcoat fiberglass insert – the same long-lasting material used in luxury yachts – available in elegant tones like Cream White (RAL 9001), Slate Grey (RAL 7015), and Sky Blue (RAL 5012). For an additional visual edge, Pearl Grey is also available.

Every detail has been designed to enhance your comfort and peace of mind: from the oiled spruce cladding to the 2-meter chimney with heat guard and cap, to the included spruce steps and floating thermometer. And because we believe that outdoor luxury should be effortless, the insulated thermal cover comes included with every Black Pearl 1.

Fully customisable to match your style and needs:
Whether you’re creating a tranquil escape at your home or adding an eye-catching feature to a guest retreat, Black Pearl 1 adapts beautifully to your preferences. Choose from a wide range of accessories including massage systems, lighting, filtration solutions, and multiple exterior finishes – all with premium craftsmanship.
