Perfect for Home or Commercial Use
Whether you're building a personal wellness sanctuary or outfitting a spa or gym, our DIY sauna kits deliver professional-quality materials at competitive prices.
Note: Your sauna shipment will include an all-glass door, though some photos may display a glass wall for reference. Backrests are shipped flat; if you'd like an angled backrest, additional spacers can be easily created on-site to achieve your desired pitch.
Note: Wall boards run in the standard horizontal direction unless room width exceeds 8 ft; in such cases, an interior seam will be added where two boards meet to span the width.
