Abachi (African Willow)

Abachi is an exotic tropical wood originating from West and Central Africa, most commonly from the tree species Triplochiton scleroxylon. In saunas, it is used mainly for benches, backrests, headrests and other contact elements of the interior. It is characterised by very low density and minimal thermal conductivity, which means it does not overheat even […]

Acrylic (PMMA – Polymethyl Methacrylate)

Acrylic is a synthetic polymer known as PMMA (polymethyl methacrylate), used as the primary surface material for the shell of hot tubs, tubs and wellness equipment. It is a solid, non-porous and UV-stable plastic that can be thermoformed into ergonomic shapes. In hot tub construction, it forms the outer layer that is in direct contact […]

AISI 304 (Stainless Steel)

AISI 304 is an austenitic stainless steel containing roughly 18% chromium and 8% nickel, and it is among the most widely used stainless grades in manufacturing. The chromium forms a thin passive oxide layer on the surface that protects the material from oxidation and re-forms by itself after scratching. In wellness construction, AISI 304 is […]

AISI 316 (Stainless Steel)

AISI 316 is a high-grade austenitic stainless steel containing chromium, nickel and molybdenum, designed for use in aggressive and humid environments. The presence of molybdenum significantly increases corrosion resistance, particularly on contact with chemically treated water, chlorine or a saline environment. In the wellness sector, it is used to manufacture jets, structural elements, fasteners and […]

Aristech Acrylics® (USA)

Aristech Acrylics® is a US manufacturer of premium acrylic sheets used to produce shells for hot tubs, pools and wellness equipment. The material is continuously cast acrylic (PMMA – polymethyl methacrylate), characterised by high density, non-porosity and a homogeneous structure. It forms the interior surface of the hot tub, which is in direct contact with […]

Aspen Wood (Sauna Benches)

Aspen wood is a soft hardwood commonly used for sauna benches, backrests and other interior contact surfaces, thanks to its low thermal conductivity and light, even appearance. Aspen contains no resin, which eliminates the risk of a sticky surface or heat-induced staining. The wood has a low density and a fine grain, keeping the surface […]
