The answer to this requires some careful thought. This is because it is dependent on a number of important factors including the size and height of the steam room and the materials to be used for the walls.
Experince tells us that the ideal height of a steam room should be 2.1 metres, otherwise the steam has a tendency to drift past the bather into the ceiling area. However, the greatest factors in the formula are the volume of the room and the material from which the walls are made. Acrylic or shower panels are very efficient, ceramic tiles less so and stone or marble much less so.
To help you decide, we reproduce a table below which shows guidance for the main categories. If you find it confusing, or would like some help in deciding please give us a call, we would be delighted to help.
The table shows recommended steam generator power (kW) versus room volume (m³) for a ceiling height of 2.1m.
| Power | Shower Panels | Ceramic Tiles | Stone |
|---|
| 3kW | 3m³ | 1.4m³ | n/a |
| 4.7kW | 4m³ | 2m³ | 1.4m³ |
| 6kW | 8m³ | 3m³ | 2m³ |
| 7.7kW | 10m³ | 4m³ | 3m³ |
| 9kW | 15m³ | 6m³ | 4m³ |
| 10kW | 17m³ | 7m³ | 5m³ |
| 12kW | 18m³ | 8m³ | 6m³ |
| 14kW | 20m³ | 9m³ | 8m³ |
