Looking for a sauna near Dundrum?
Helios Dundrum closed on 16 August 2026. Thank you to everyone who made it such a special spot.
Our nearest sauna: the Floating Sauna at Coal Harbour
About 20 minutes from Dundrum, the Helios Floating Sauna at Coal Harbour, Dún Laoghaire is Ireland's first floating sauna. A wood-fired sauna set right on the water, an ice bath for the hot-and-cold ritual, and panoramic views across the harbour.
Or head to Bray
Our Bray Rooftop Sauna sits on the seafront in Co. Wicklow, with woodfire heat, cold plunge and panoramic sea views.
A new Helios is coming to south Dublin
