Something extraordinary has happened in Ireland over the past several years. The country that gave the world the seaweed bath — a wellness tradition going back centuries — has quietly become one of the best places in Europe to find a sauna.
When I first started looking for saunas in Ireland around 2019, the options were thin. A hotel spa here, a gym steam room there. Today, there are hundreds of venues. Coastal barrel saunas overlooking the Atlantic. Wood-fired Finnish saunas beside freshwater lakes. Contrast therapy studios in Dublin city centre. Community saunas on island beaches in Mayo. The transformation has been remarkable.
This is the complete guide to saunas across Ireland — county by county, from Dublin to Donegal. Whether you're planning a Wild Atlantic Way road trip or just looking for something different to do on a Sunday, you'll find something here.
Why Ireland Has Become a Sauna Nation
The Irish relationship with cold water is ancient and deep. Sea swimming has always been part of life here — the Forty Foot in Sandycove, the Guillamene in Waterford, the Blackrock Diving Tower in Galway. The post-pandemic explosion of wild swimming groups brought that tradition to a whole new generation.
Saunas arrived as the natural companion to cold water swimming. You're already getting in the sea in January. Why not have a wood-fired barrel to warm up in afterwards? That logic — so obvious it seems inevitable — is exactly what drove the explosion of Wild Atlantic Way saunas from 2020 onwards.
The Scandinavian influence helped too. Irish people who had worked or travelled in Finland, Norway and Sweden brought the culture back with them. The idea that a sauna isn't a luxury but a basic amenity — something every community should have access to — took hold quickly.
Dublin and the Greater Dublin Area
The Sea Sauna is Dublin's most scenic sauna experience, positioned to give you everything the capital's coastline has to offer. Riverbank Sauna brings the experience into the city proper, while The Outcast Saunas has built a loyal community following.
For suburban Dublin, The Barrel Sauna Dundrum and The Barrel Sauna Tallaght bring the Finnish barrel sauna experience to south and west Dublin respectively. The Hot Box Sauna Inchicore is one of the city's finest contrast therapy venues. Spir Sauna Dublin and Saunos at Wanderers FC round out a genuinely excellent city scene.
Just south of Dublin, Helios Sauna Bray is worth the short DART ride — coastal Bray has been one of Ireland's best-kept wellness secrets for years, and Helios is a highlight. Sandycove Store & Yard sits near the famous Forty Foot swimming spot — you can do both in the same morning. Fad Saoil Sauna, Sláinte Saunas and The Wood Fired Sauna are all excellent options across the greater Dublin area.
Cork
Cork's wellness scene has grown substantially. In the city, The Hot Box Cork City offers excellent contrast therapy, while Wildwood Sauna Cork City brings a more rustic feel. The Sauna Snugg is Cork's most intimate sauna experience.
Head south and you reach the Wild Atlantic Way proper. The Cosy Sauna Kinsale is a lovely complement to the famously beautiful harbour town. Coastal Roast Sauna and Coastal Cabin Beach Sauna are both exceptional Wild Atlantic experiences. Cedar & Steam Sauna and Happy Place Saunas in West Cork are worth going out of your way for. Hidden Sauna Bridgefield, Hoco Sauna, and My Haven Sauna complete a remarkably comprehensive county-wide offer.
Galway
Galway has one of the most interesting sauna scenes in Ireland — a mix of city contrast therapy and wild coastal experiences in the surrounding county.
Galway City Sauna serves the city centre, a short walk from Eyre Square. Inis Wellness in Salthill brings views across Galway Bay and proximity to the famous Blackrock Diving Tower — you can plunge in Galway Bay and use the sauna in the same visit.
Out in the county, Sauna Fiáin at Renville Pier is extraordinary — a hand-built Finnish sauna where you plunge directly into the Atlantic. Driftwood Sauna Galway runs Full Moon events with fire pits and the kind of atmosphere that's hard to replicate indoors. Folláine Sauna at Annaghdown Pier on Lough Corrib — twenty minutes from the city — is one of Ireland's most peaceful and beautiful settings. And Oileánra Seaweed Baths & Sauna in Lettermullen on the wild Connemara archipelago offers one of the most extraordinary seaweed bath and wood-fired sauna combinations in the country.
Kerry
Kerry is where the sauna boom meets Ireland's most dramatic coastal scenery. The county has been transformed in the past few years.
Skellig Sauna in Portmagee might be Ireland's most dramatic sauna setting — you heat up in a wood-fired cabin with views across Portmagee Channel towards the Skellig Islands. Then you plunge in the Atlantic. The UNESCO World Heritage Site is visible on clear days. This is world-class.
Happy Days Sauna at Banna Beach is a custom-built barrel sauna behind one of Kerry's finest Blue Flag beaches. Kingdom Sauna Derrynane sits at Derrynane — one of Ireland's most beautiful National Park beaches — with views over the bay and surrounding mountains. Collins's Seaweed Baths Ballybunion, open since 1932, is one of only four remaining authentic seaweed bathhouses in Ireland. Killarney Thermal Spa brings luxury spa treatment to Kerry's famous lake town.
Sligo
Sligo punches well above its weight. Voya Seaweed Baths Strandhill is the original Irish seaweed bath experience — certified organic seaweed harvested from the North Atlantic, heated in private wooden baths on the shores of Strandhill with views of Knocknarea mountain. This is what all seaweed bath experiences aspire to be.
Kilcullen's Seaweed Baths in Enniscrone have been open since 1912 and are in their fifth generation of family ownership. West Coast Sauna Co. at Enniscrone Pier has added a Finnish sauna to the town's already-excellent wellness offering. The Hot Box Sauna Rosses Point offers Finnish saunas and cold plunges at Deadman's Point with views of Knocknarea and Sligo Bay.
Mayo
Mayo's Wild Atlantic Way coastline is home to some of Ireland's most dramatic sauna experiences. Sabhna Saunas operates on two Achill Island beaches — Dugort Beach and Keel Beach — offering the extraordinary experience of a Finnish sauna on one of Ireland's most rugged island coastlines. Big Dipper in Killadoon near Louisburgh is a gem. Sláinte Saunas Wild Atlantic operates at Clew Bay with views of Croagh Patrick. South Sligo Wild Sauna near Charlestown adds another option to this beautifully served western coastline.
Donegal
Donegal is Ireland's wild north, and its sauna scene reflects that character — rugged, dramatic, often spectacular. Sliabh Liag Sauna at Teelin Pier is possibly Ireland's most dramatic sauna location — the pier sits beneath Europe's highest sea cliffs, and the combination is unforgettable. OM Saunas at Rossnowlagh Beach, Salt and Ember Sauna in Bundoran, Cocoon Sauna in Portnablagh, The Hot Barrel Sauna at Portsalon, The Sea View Sauna venues at Culdaff and Shroove in Inishowen, The Swilly Sauna at Rathmullan, and Wild Atlantic Sauna Dooey all contribute to a county that has truly embraced the wellness movement.
Clare
Sauna Suaimhneas in Dough, Lahinch is Clare's standout sauna experience — Lahinch is one of Ireland's great surf towns, and combining a surf session with a sauna and sea plunge is a perfect day out.

The sauna boom has reached every corner of Ireland. Carlow, Cavan, Kilkenny, Laois, Leitrim, Limerick, Meath, Offaly, Roscommon, Tipperary, Waterford, Westmeath, Wexford and Wicklow all have sauna venues now.
