Spa & Wellness Construction in Orange County
Spas are among the most technically demanding interiors we build. Wet rooms, steam and sauna, hydrotherapy, quiet treatment rooms and polished guest areas all sit side by side. Americal has built spa and wellness spaces for resorts, hotels, day spas and medical aesthetics practices across Southern California.
From reception to the wet areas
A spa is a sequence: arrival and reception, retail, locker rooms and vanities, relaxation lounges, treatment rooms, and the wet areas — showers, steam, sauna and pools. Each needs its own substrate, drainage, ventilation, acoustics and lighting.
Waterproofing and moisture control are where spa projects succeed or fail. We sequence wet-area work carefully, verify it before close-in, and pair it with the custom millwork, stone and lighting that guests actually see.
