Rules on displaying hot tubs in shops and public places should be reviewed, according to a report into a fatal outbreak of Legionnaires’ disease.
The Health Protection Agency (HPA) report said a hot tub on show at JTF Warehouse in Stoke-on-Trent was the probable source of an outbreak in 2012.
Richard Griffin, 64, and 79-year old William Hammersley, both died and 19 other people caught the disease.
The HPA said hot tubs posed a health risk if not regularly maintained.
BBC News has not been able to contact JTF Warehouse for a comment following the HPA report.
