It is recommended that guidance for water management be followed where appropriate.
The volume of water, operating temperature, location of the pool (e.g. outside) and bather loads all contribute significantly to water quality, which means that disinfection is essential for maintaining standards in ice baths.
Water in spa pools should be free from irritant substances, chemicals and infectious agents at levels which may be harmful to health. For information and advice relating to the clean water management of your ice bath, advice can be found in document HSG282 – The control of legionella and other infectious agents in spa-pool systems, produced by the Health & Safety Executive. This document details the management of water, chemical treatments and cleaning.
It is recommended that water, if kept in the ice bath, be regularly tested for quality, or seek advice from a water-treatment professional, who may recommend a Chlorine treatment, which takes longer to react in cold water and ensure the correct does is used.
