Sauna Kits (2025): Best Outdoor and Indoor Options
Updated February 2025 — Backyard Sauna Pro
A sauna kit is the practical middle ground between a custom-built sauna ($15,000+) and a cheap portable tent ($150). You get real cedar, real heat, and a permanent installation — without the contractor bill. Here is what to buy and what to know before you order.

Types of Sauna Kits
Outdoor barrel sauna kits
The most popular type in North America. Curved cedar staves form a barrel shape that heats efficiently, drains naturally, and looks intentional in a backyard. Pre-cut panels mean assembly is straightforward — two people, one day, basic tools. Heater sold separately. The barrel shape is not just aesthetic: the round interior has less dead air volume than a rectangular room of the same floor area, which means faster heat-up and lower energy use.
Indoor traditional sauna kits
Flat wall panels, floor, ceiling, and bench components that assemble into a rectangular sauna room inside an existing space — basement, garage, bathroom addition. These kits require more planning around electrical, vapor barriers, and ventilation but give you a year-round indoor sauna without dealing with winter conditions. Best for buyers who want the authentic traditional experience inside the home.
Plug-in infrared kits
Pre-assembled panels with built-in infrared heaters that run on standard 120V. No electrician needed. Fits in a corner of a bedroom or spare room. Lower temperature than traditional saunas (120-140°F vs 160-185°F) but much lower barrier to entry. Best for apartment dwellers or anyone who cannot run a dedicated 240V circuit.
