Earlier this month, Dublin City Council granted planning permission to the firm for planning retention for five saunas and three plunge pools as part of a 'Hot Box Sauna' unit at Unit 5 Goldenbridge Industrial Estate, Tyrconnell Road, Inchicore, Dublin 8.
The Council granted planning permission after a wave of support in submissions from users of the sauna facility.
The firm also has a planning retention application before Dun Laoghaire Rathdown Co Council for its sauna operation adjacent to Killiney beach and a decision is due next week.
Last year, the sauna operators opened its flagship operation at the Google Ireland-owned Hot Box Sauna Bolands Mills in Dublin's Docklands as part of a €2m investment.
Today, The Hot Box Sauna operates from eight sites around the country and includes Counties Cork, Meath and Sligo outside the capital.
In a press interview last year, co-founder Dan O’Connor said: "Our model is scalable, our brand is strong, and the demand is global".
"We're ambitious and we want to see The Hot Box become a name synonymous with world-class sauna experiences, whether you’re in Dublin, Los Angeles, or anywhere in between," he added.
The Hot Box Sauna was co-founded by Mr O’Connor and his friends Luke Williams and Liam Irwin in 2021 as a self-built sauna trailer in Co Meath.
