Inside every install — pure cedar
We handcraft and install custom cedar saunas, cold plunges, and hot tubs for St. Louis homeowners and home builders. Specialists in custom sauna installation across St. Louis. Family-owned craftsmanship — fully built cedar saunas, often more attainable than you might expect.
Most people assume custom sauna installation in St. Louis is a luxury they can’t afford. The reality surprises them. Because we build direct through Satori Cedar Spas — our own St. Louis workshop — there’s no middleman markup and no separate contractor margin.
We have long-standing direct relationships with Pacific Northwest sawmills. This lets us select exceptional Western Red Cedar while avoiding the distributor markups that often drive up costs.
Here’s how custom cedar sauna installations typically compare to common alternatives.

St. Louis Sauna Company grew out of Satori Cedar Spas — our family-owned workshop that handcrafts American-made cedar wellness products and ships them across the country.
Born from a deep love of hot springs, saunas, and fine woodworking, we’ve spent years perfecting the craft. As Satori’s reputation grew nationally, we realized St. Louis deserved its own dedicated installation service — rooted right here in our city.
We know the neighborhoods, the basements, the backyards. We know how to find the sanctuary hiding in every overlooked space, and how to build it beautifully — handcrafted, American-made, and built to last.
