Saunas

Shop premium home saunas from Peak Flow Fitness — including infrared saunas, traditional steam saunas, and outdoor barrel saunas from industry-leading brands like Golden Designs and Dundalk Leisurecraft. Whether you're looking for a compact 1–2 person unit for a spare room or a spacious 6-person outdoor sauna for your backyard, our collection includes options for every space, budget, and wellness goal.

Infrared saunas deliver deep-penetrating heat at lower temperatures, making them ideal for daily recovery sessions, joint relief, and improved circulation. Traditional steam saunas provide the classic high-heat experience that promotes intense sweating and deep relaxation. Every sauna in our catalog is built with premium materials — Canadian red cedar, hemlock, and tempered glass — backed by manufacturer warranties and designed for years of reliable performance.

At Peak Flow Fitness, we carry only authorized dealer inventory, which means your warranty is fully protected and your sauna ships factory-direct with white-glove delivery options. Orders over $999 ship free anywhere in the continental US. Not sure which sauna is right for your space? Call our recovery equipment specialists at 646-921-5221 for personalized guidance. Browse our Cold Plunge & Ice Baths collection to build a complete contrast therapy setup, or explore Red Light Therapy devices to add another layer to your home recovery system.
