A new, natural stone – effect spa joins the Treesse catalog: a product inspired by natural aesthetics and reflecting one of the latest trends in the world of design. Rock is a whirlpool spa featuring a special gres stoneware cladding that faithfully reproduces the look of natural stone with extraordinary realism. This design choice not only recalls the authentic beauty of outdoor settings, but also delivers a unique tactile and visual experience.
In open-air environments, such as gardens or terraces, Rock appears almost like a natural pool emerging from the rock itself; the refined finish chosen for its construction, enriched with subtle veining, enhances the impression of a true landscape element. In indoor wellness areas, on the other hand, Rock stands out for its soft, delicate color tones that invite relaxation. The gres stoneware used for the cladding is a durable material, resistant to weather conditions and easy to maintain. Rock features a sophisticated and high-performance whirlpool system; the internal shape is carefully designed to create a welcoming and comfortable environment.
All of this ensures a complete, enveloping, and multisensory relaxation experience. With its refined appearance and outstanding comfort, the Rock whirlpool spa was designed for Treesse by internationally renowned designer Marc Sadler. This spa, inspired by the beauty of natural rock, can also be combined with the Step-Rock system: a set of modular steps that can be assembled into a convenient access staircase, adaptable to the requirements of any space. Step-Box steps are also available with a stone-effect finish, ensuring perfect integration with the Rock whirlpool spa.
Whether placed in a garden, on a terrace, or in a dedicated wellness area, the Rock natural stone-effect spa adapts seamlessly to any setting, always creating an exclusive and sophisticated relaxation space, with an aesthetic inspired by natural landscapes and all the comfort typical of Treesse whirlpool spas.
