Buying Guide: What to Consider

Space Requirements

Portable Steam Saunas: Require 3x3 feet of floor space and 6-7 feet of ceiling height. Can be stored when not in use.

Built-in Systems: Need dedicated steam room with proper waterproofing, ventilation, and drainage. Minimum 4x4 feet recommended.

Power and Electrical Needs

Most portable units plug into standard 110V outlets, while built-in systems require 220V dedicated circuits. Steam generators typically need:

• Water quality sensors

Ventilation Requirements

Proper ventilation prevents mold and moisture damage. Built-in steam rooms need:

• Exhaust fan (minimum 20 CFM per square foot)
