Saunas in St Ives: Beach Saunas and Cold Plunges

The best saunas in St Ives

Kiln Sauna is the most structured of the three, with named session types rather than walk-in bathing: a 45-minute social sauna, a 45-minute family session, private bookings and a private pavilion, plus yoga and meditation combinations. It sits above Porthmeor Beach and opens Monday, Thursday, Friday, Saturday and Sunday, with bookings released 30 days ahead.

Tan & Dowr is a handcrafted mobile sauna paired with a cold plunge at Ayr Holiday Park on Ayr Terrace, looking across St Ives Bay. Sessions run 30 or 60 minutes, with private bookings for groups of seven and monthly or weekly memberships for repeat bathers; you sign a waiver on arrival.

Mor Holan on Porthminster Beach is the smaller beach cabin, positioned about halfway along the sand next to the path toward Carbis Bay. A visiting account describes an attendant on duty, changing rooms next door, sauna hats provided and a per-person rate with the whole place available when six spots are booked.

Kiln Sauna at Porthmeor Beach

Kiln's Porthmeor cabin is wood-fired and swimwear-only, with a no-nudity and no-alcohol rule and a strict towel-on-the-bench habit. The 45-minute social session is the default choice for couples and solo bathers, while families with children aged 6 to 16 belong in the family or private sessions, where each child needs an adult on a one-to-one basis inside the sauna.

Arrive five minutes before your slot and wear your swimwear under your clothes: the changing area is very small, suitable for one person at a time, and changing time counts within your booked session. Bring two towels, a water bottle and beach shoes for the stony walk down to the water.

The stove is managed by staff, so you add water with the ladle and nothing else; essential oils and glass are not allowed inside. A sand timer helps you keep to a 5 to 12 minute rhythm with five minutes outside between rounds, and guests are asked not to take photographs or videos during communal sessions.

Tan & Dowr at Ayr Holiday Park

Tan & Dowr's sauna is mobile and wood-fired, set at Ayr Holiday Park with views over St Ives Bay, and it comes with a cold plunge rather than a sea swim as the main cold option. The published rules set a 20-minute maximum per sauna round, a 10-minute cap per cold plunge and at least 5 to 10 minutes of rest between rounds, with beginners advised to start at 2 to 3 minutes in the cold.

Opening hours are split between mornings and evenings: Monday and Friday 10:00 to 12:00 and 17:30 to 20:00, Tuesday to Thursday 17:30 to 20:00, and Saturday and Sunday 10:00 to 13:00. That shape suits a late-afternoon session after a coastal walk better than a midday dip.

There are no lockers, so keep valuables with you or leave them at your accommodation, and shoes come off before entry with a towel to sit on. Under-16s may use the sauna with a guardian but not the cold plunge, and an extra waiver is required for them.

Mor Holan at Porthminster Beach

Mor Holan's draw is its position on Porthminster Beach, with windows facing St Ives Harbour in one direction and the lighthouse in the other. It is a short-format beach sauna rather than a spa complex, and the changing rooms next door plus an attendant on watch make it easy for a solo bather to leave a bag while inside.

The cold side here is flexible: a cold shower and tin baths of cold water stand in when you do not fancy the sea. If you do run for the water, go near high tide, because a low tide leaves a long stretch of sand between the sauna and the surf.

How a session works

All three run on booked slots, so reserve before you travel, particularly for weekend mornings and school holidays. Kiln's booking calendar opens 30 days ahead and its sessions are capped by room size, while Tan & Dowr takes 30- and 60-minute bookings and private hires for seven.

Expect mixed communal sessions at Kiln and Tan & Dowr, with private bookings available when you want the room to yourselves. Swimwear stays on at Kiln, and the same is the sensible default at the other two; a towel to sit on, a second to dry with and flip-flops for the beach cover the dress code and the walk down.

Cancellation terms differ enough to matter: Kiln offers a credit or refund up to 72 hours before a session and rescheduling until 24 hours before. Read the terms when you book rather than after a plan changes.

What a St Ives sauna costs

Kiln publishes its rates openly: the social sauna is £12, the family session from £8, a private sauna for up to 11 people is £100 for 45 minutes, and the private pavilion runs £200 for 45 minutes or £360 for 90 minutes. Combination sessions include meditation plus sauna at £15 and yoga plus sauna at £20.

Tan & Dowr charges £9 for 30 minutes and £16 for 60 minutes per person, with a group session for seven at £80 for the hour. Memberships cover a set number of half-hour sessions each month and carry a three-month minimum, while a weekly option suits shorter stays.

Mor Holan is priced at £12 per person according to the Saltings journal, with the cabin yours when six places are taken.

The cold-water side

The Atlantic is the real plunge in St Ives, and Kiln's Porthmeor position puts the sand directly below the cabin door. Kiln's own guidance stresses that sea swimming is at your own risk and that you need to be a capable swimmer comfortable with cold water and changeable conditions.

Tan & Dowr offers a contained cold plunge instead, which removes the walk and the tide variable but comes with its own limits: 10 minutes per plunge, 20 minutes a day for experienced users, and 2 to 3 minutes to start. Mor Holan covers both bases with the sea, a cold shower and tin baths beside the cabin.

Tide and swell decide how good the sea plunge is on any given day, so check a surf or tide forecast for St Ives Bay before choosing a slot. A falling tide on Porthmeor widens the beach and lengthens the run back to the sauna.

What to expect: small rooms and weather

These are compact operations rather than leisure centres. Kiln's changing area fits one person at a time, Tan & Dowr has no lockers, and Mor Holan relies on the public changing rooms beside the beach, so pack light and arrive ready to change quickly.

Cornish weather shapes the session as much as the stove does: wind and rain make the run to the water bracing, and the beach at Porthmeor is stony enough to want shoes. Kiln's sessions run on Monday, Thursday, Friday, Saturday and Sunday, so Tuesday and Wednesday evenings belong to the other two.

Getting there

Porthmeor Beach sits on the seaward side of town, a short walk from the Tate St Ives end of St Ives, and the Kiln cabin is above the sand; the venue publishes what3words coordinates for the exact spot. Mor Holan is halfway along Porthminster Beach by the Carbis Bay path, which is the easier reach from the harbour side of town.

Tan & Dowr is at Ayr Holiday Park on Ayr Terrace, postcode TR26 1EJ: enter the park, head for the Quarterdeck and follow the signs. If you are coming by train, St Ives station leaves a walk or a short bus hop to all three, and the coast path links Porthmeor and Porthminster on foot.

If you are touring other Cornish saunas, the wider scene around the county is worth a day of its own, and the same booking-first logic applies to saunas in Aberdeen or saunas in Birmingham on a longer UK trip.

Plan Your Visit

Choose Kiln for a wood-fired communal session above Porthmeor with a sea swim, Tan & Dowr for a timed sauna-and-plunge routine with evening slots, and Mor Holan for a shorter beach session with an attendant on hand. Book a slot before you travel, keep the session short and the breaks long, and bring two towels and shoes for the sand.

Stay hydrated, skip alcohol before bathing, leave the sauna if you feel unwell, and speak to a doctor first if you have a heart condition or are pregnant.
