A Floating Sanctuary in Dublin Bay

Located in the heart of Dun Laoghaire Harbour, our floating sauna brings together intense heat and immediate access to the sea. It is a rare space where the urban landscape of Dublin meets the raw elements of the coast.

Whether you are a daily harbor swimmer, a commuter looking to decompress, or a visitor exploring the pier, the floating sauna is a focal point of the waterfront. If you are looking for a sauna in Dun Laoghaire or a truly unique floating sauna in Dublin, this is where the city’s pulse slows down.

How Sessions Feel

The experience is defined by the water. On calm mornings, the sauna is a glass-fronted sanctuary of stillness, perfect for meditation and restorative heat. As the harbor wakes up, the energy shifts—you’ll hear the gentle lap of waves against the hull and feel the refreshing coastal breeze during your cooling breaks.

It’s a communal atmosphere where the shared experience of the "big dip" creates an instant bond. Whether you’re here for a quiet solo sweat or a catch-up with friends, the floating sauna Dun Laoghaire experience is designed to be inclusive, grounded, and deeply refreshing.
