The Trinity XL Combination Sauna is a powerful all-in-one wellness system that combines UL-listed Spectrum Plus infrared heaters, a traditional steam sauna heater with vulcanite stones, and medical-grade Spectrum Red Light™ Therapy. This advanced design delivers a complete sauna experience with infrared heat, steam therapy, and light therapy in one unit.

Advanced 3-in-1 Sauna Technology

This is the only sauna that combines true UL-listed infrared heater panels with a traditional sauna heater. The infrared system uses short-wave far-infrared heat that penetrates deeply into muscles and joints, helping you sweat up to 25 times more than standard carbon heaters.

The traditional 4.5kW sauna heater allows you to pour water over stones to create steam, delivering a classic sauna experience with intense heat and humidity. This combination ensures you get both deep tissue benefits and full-body heat.

Red Light Therapy Benefits

The built-in Spectrum Red Light™ Therapy system uses 192 medical-grade LED diodes at 650nm to support skin health and recovery. This phototherapy helps stimulate collagen production and enhances your overall wellness routine while you relax.

Premium Materials & Comfort

The interior is crafted from antimicrobial Western Canadian cedar, which naturally resists mold, bacteria, and fungus. The exterior uses Thermal Plus Aspen, designed to resist warping, rotting, and decay for long-term durability.

An extra-large two-tier bench system provides comfortable seating, while 8mm tempered glass improves heat retention and creates a clean, modern look.

Smart Controls & Entertainment

The sauna includes a built-in LCD Wi-Fi touchscreen controller with Bluetooth audio. Enjoy music through integrated 6-inch Hi-Fi speakers while controlling temperature, lighting, and session time with ease.
