For a 2m² room, the towel rail size depends on the heating requirements of the room. You can estimate this using the required heat output measured in British Thermal Units (BTUs) or watts.
Here’s a quick guide:
1. For a typical bathroom with average insulation, you need about 100 watts or 341 BTUs per square meter.• For a 2m² room, the total heat requirement would be around 200 watts (or 682 BTUs).
2. Towel rail size: Look for a towel rail that provides at least 200 watts (682 BTUs). A small or medium-sized towel rail would likely suffice.
