We are having some heating issues in our changing rooms and shower areas. Due to cost issues, it may be some time before this gets fixed. Does anyone know of any guideline / advice / recommendations about the minimum temperatures within these areas, or if there is any? They are very cold in this weather!! This information could help me persuade management to spend the money needed to fix the problem (and help a lot of male egos). Thanks Steve.

Steve Presumably you are talking about showers and changing room in a workplace such as factory or construction site. Not local swimming baths. Have a look at the Workplace Regs but there is nothing prescriptive about temps in changing rooms http://www.hse.gov.uk/pubns/indg293.pdf. Try talking to management and suggest obtaining some temporary heating Steve
