Can anyone confirm what the definition of the above named spaces include? Physiotherapy is self-explanatory, but does hydrotherapy only include pool type treatment, or would bathing rooms (tub rooms) be included in the hydrotherapy definition? 

For treatment areas, would this include all private medical offices where individual assessment of a patient is conducted? If so, can I meter the row of rooms together or must each room be individually metered? Also, would the treatment definition include mental health group support service space? aka a smudging room or chapel or gathering space?
