We suggest looking for an exterior cabinet constructed from weatherproof or UV-resistant materials. Less commonly, you find tubs made of fiberglass or stainless steel. Older and vintage-inspired hot tubs are sometimes made from wood like cedar, redwood, teak or recycled metal. Remember, the cabinet of your hot tub is the part that everyone sees. Vinyl hot tubs are often cheaper but can be of lesser quality. Generally, acrylic and rotomolded hot tubs are popular because of their durability. Quality materials and insulation Most hot tubs are made of acrylic, polyethylene, vinyl or other types of plastic. Pay attention to the different seating, jet and ambiance features that you like most as you compare models.
