Can you give us examples of mistakes in spa design?
The top three are:

1. Acoustics - where many times you can hear what people are talking about in the next room, and separating active and passive, paying and non-paying and keeping the spa treatment areas separate and silent.

2. Mechanical and electrical - that is often forty percent of the budget and you should get it right, you don’t want it to be too hot or too cold and client comfort is paramount.

3. Air changes - are also important since the quality of the air is so important to therapists
health and wellbeing.
