Kohler Invigoration® Steam Generators: How to Choose the Right Size for Your Steam Room (7 kW–30 kW)
Designing a private steam room is one of the most rewarding upgrades you can add to your home or wellness space. But before you experience the soothing benefits of steam, choosing the correct steam generator size is critical.
At EliteWellnessHQ.com, we carry the full line of Kohler Invigoration® Steam Generators ranging from 7 kW to 30 kW, ensuring you get the perfect match for your room size and design.
Why Generator Size Matters
The steam generator is the heart of your steam room. An undersized generator may struggle to maintain temperature and humidity, while an oversized unit wastes energy. Kohler’s Invigoration® series provides consistent steam, quick warm-up, and years of reliable performance—but only when properly sized.
Step 1: Calculate Your Steam Room Cubic Footage
Accurate sizing starts with knowing the total cubic footage of your steam enclosure.
Formula:
Example:
If your steam shower measures 6 ft (L) × 5 ft (W) × 8 ft (H):6 × 5 × 8 = 240 ft³
Adjustments for Materials
Certain materials hold more heat and require a power boost:
-
Marble, stone, or glass: Add 25% to the cubic footage.
-
Exterior walls or large windows: Add another 10–15%.
After adjustments, use this final figure to select the right generator.
