Wellness That Works Below Grade
A high-performing wellness basement starts with the envelope: insulated slab system, vapor control, and balanced ventilation. On that foundation, select rubber or cork composite flooring in gym areas for impact and acoustics, with porcelain tile in wet-adjacent zones. Wall-to-wall mirrors visually expand the room—float them off the wall with Z-clips and leave a top vent gap to prevent condensation pockets.
Sauna, Cold Plunge, and Showers
For daily recovery, a modular infrared sauna with tempered glass and integral ventilation beats fully custom steam in complexity and humidity. If you’re adding a cold plunge, isolate it on a drainable, tiled pan with a floor cleanout and GFCI-protected receptacle on a dedicated circuit. In the bath, specify a solid-surface shower pan, large-format tile, and epoxy grout to tame maintenance.
Air Quality, Noise, and Lighting
Pair a ducted dehumidifier (45–50% RH) with a quiet ERV for fresh air during workouts. Line return runs to reduce equipment noise bleed and add acoustic panels behind slatted wood for premium aesthetics. Use scene-based lighting—bright 3500K for training, 2700–3000K dim-to-warm for recovery—with linear wall-washers that make low ceilings feel taller.
Power, Data, and Storage
Install floor boxes for treadmills/rowers, a surge-conditioned rack for AV/streaming, and ventilated cabinets for bands and mats. Keep towels and cleaning supplies in moisture-resistant millwork lifted on aluminum plinths. Leak sensors under the bar sink and at mechanicals protect finishes.
