L.A. Spas uses only the finest cast acrylic surface, exclusively for high luster and lasting beauty. Solid unibody, pressure-treated wood frame and solid footwell reinforcement, provide outstanding shell stability. Our unique cabinet saver waterfall lip forces splashing water away from the spa while protecting the cabinet. The L.A. Spas reinforced footwell is structurally designed with a mixture of layered composite material that supports the entire shell structure to rest solidly on the ground, providing maximum structural integrity. L.A. Spas subframes are specially built with moisture resistant pressure treated lumber that provides heavy duty long-term structural support. L.A. Spas also integrates an ABS sealed bottom vapor barrier that eliminates moisture creep. Features and options may vary from model to model, however, every L.A. Spas offers the same heavy duty construction, equipment, and materials.
