Saunas by the Sea in Cornwall

Feel the heat by the sea in Cornwall…

Autumn vibes and blustery weather has got us thinking about warm and cosy days by the sea. What better way to boost your wellbeing and warm up after beach adventures than with a sauna beside the waves?

The mobile saunas popping up all over Cornwall aren’t only a welcome sight when our fingers are numb and our lips are blue, they are good for our health and becoming quite the way to socialise, too. In fact, saunas were originally invented as communal spaces for getting together, relaxing and cleansing in harsh Nordic winters.

It wasn’t until later that the positive physical and mental impact of sweating it out was clocked: increased heart rate, improved circulation and enhanced detoxification, and that’s just for starters. The combination of hot and cold therapy – alternating between icy water and intense heat – isn’t just strangely addictive, it reduces muscle inflammation, boosts the immune system and offers a holistic approach to health and relaxation.

Whether you’ve braved a coldwater dip, want to thaw out after a surf or beach walk, or are keen to reap the benefits of hot and cold therapy, try these saunas by the sea in Cornwall.

WATER & STONE at LIME HOUSE YOGA, Nr Perranporth

Prepare yourself for absolute Zen when you arrive at this beautiful setting atop the dunes of Penhale that roll to the ocean’s edge in the distance.

Try an hour’s session at your own pace, or join in a  guided sauna ritual for the ultimate cleanse and energy shift.

Individual and private sessions available.

Olla Hiki Sauna, NEWQUAY HARBOUR

Now there’s really nothing like a sauna after a winter surf or sea dip. Which is why Olla Hiki scoped out locations where they’d spotted surfers and swimmers dashing out of the waves, for their mobile sauna. From Fistral Beach to Watergate Bay, this iconic little hot box has bagged some truly beaut spots, and has now settled beside the wonderful winter swimming spot of Newquay Harbour until February 2025. It’s become quite the social hub too, with special events such as breathwork sessions, sound baths and full moon rituals, as well as extra little treats such as a salt scrub, essential oils and birch whisk massages. Community memberships and single sessions available. 

Escape TO THE Sauna, St Austell, FALMOUTH and Hayle

Saunas by the Sea, Polzeath and Harlyn

Creating a trio of oases on the north coast of Cornwall, Saunas By The Sea have not only popped wood-fired sanctuaries right beside the waves at Harlyn Bay near Padstow and Baby Bay in Polzeath, but they have also opened a Wild Spa and Wellness Garden with a sauna, plunge pool and a range of classes to promote the healthy lifestyle.

Or you can head to the Motts Sauna at Menheniot, where there is a river and shower for cooling off and a lovely area to relax in nature and sit round the fire. During the summer, from April to Ocotber, the Millendreath sauna moves to the rolling parkland of the Mount Edgcumbe. Private bookings, communal sauna sessions, and collaborations with local wellbeing practitioners are available at all locations.

Rising Embers Sauna, Penzance

Bringing the Finnish culture to the far west shores of Cornwall, there’s no doubt that Rising Embers was inspired by the wild swimming community of Penzance. Where one of Cornwall’s biggest swimming communities dip in the Lido and Mounts Bay come rain, hail or snow, it stands to reason that Rising Embers had the sense to pop a wood-fired sauna in St Anthony Gardens, footsteps from the shoreline. Warming the hearts and fingers of the passionate all-weather dippers, this seaside sanctuary eases the muscles and the mind in every season.  

Ocean Soul Sauna, Bude

The sea pool in Bude is a Mecca for both coldwater dippers and serious sea swimmers all year round.

Alternate the warmth with a dip in the sea pool or a bucket shower to reap the benefits of hot and cold therapy, or bask in the warmth and leave with a glow from inside and out. 

Spa Soma, Penryn

If you’re looking for a wild eco spa that really gets you back to nature, then Spa Soma is the place to go. Squirrelled away in a rustic oasis near Penryn, here you can alternate between a natural spring-fed pool, a wood-fired hot tub and the wood-fired sauna. It’s up to you if you want to gather your friends for an exclusive session, or even create a bespoke retreat day with the likes of yoga, meditation and a south bath thrown into the feel-good mix. 

SAUNASSA NORDIC SPA, NEWQUAY

Close the bay beaches in the heart of Newquay, you can navigate through the invigorating stages of heat and cold in a brand new outdoor setting at Saunassa Nordis Spa.
