Luna Hut (Bexhill)
South East Bexhill-on-Sea, East Sussex · cold dip: sea
Luna Hut runs a sauna beside the modernist De La Warr Pavilion on the Bexhill-on-Sea seafront, bringing the wood-fired beach-sauna format to one of the most architecturally distinctive spots on the Sussex coast.
Rewild Sauna
South East Bracklesham Bay, West Sussex · cold dip: sea
Rewild Sauna sits at Bracklesham Bay in West Sussex with views across the water to the Isle of Wight. It marks the western end of the Sussex coast's beach-sauna run.
Beach Box Sauna Spa
South East Brighton, East Sussex · cold dip: English Channel sea dip
Beach Box Sauna Spa is the venue that started Brighton's beach-sauna scene and remains its best-known fixture, running year-round wood-fired sessions from two converted horsebox trailers and a 12-seater cedar cabin with panoramic ocean views at Sea Lanes on Madeira Drive. The cold plunge is a direct dip in the English Channel a few steps away, and the annual Brighton Sauna Festival pop-up village lands on the pebbles next door. The operator also runs mobile bookings for events along the south coast.
Luna Hut (Brighton, Sea Lanes)
South East Brighton, East Sussex · cold dip: sea
Luna Hut's Brighton site sits at Sea Lanes on Madeira Drive, next to the national open-water swimming centre, which makes it the natural choice for warming up after a cold sea swim. Billed as Brighton's first sauna cafe, it wraps the heat-and-cold-plunge ritual in a hospitality format, and it shares the Madeira Drive cluster with Beach Box so the two are easy to compare on one visit.
Luna Hut (Eastbourne)
South East Eastbourne, East Sussex · cold dip: sea
Luna Hut's Eastbourne site sits on Grand Parade near the Wish Tower, extending the operator's Sussex seafront network eastward with the same wood-fired sauna and sea-dip formula.
Sea Scrub Sauna (Folkestone Harbour Arm)
South East Folkestone, Kent · cold dip: cold plunges and sea access
Sea Scrub's newest and biggest site opened on Folkestone's Harbour Arm in March 2026 and ranks among the largest beach spas in the country, with multiple saunas plus a fire pit, hot tub and wellness cafe on site. Folkestone's regeneration drive made this one of the highest-profile openings in the regional scene.
Steam Punk Sauna
South East Folkestone, Kent · cold dip: sea
Steam Punk Sauna offers a more intimate wood-fired session for small groups near Mermaid Beach in Folkestone. It is the smaller-scale alternative to Sea Scrub's large Harbour Arm site in the same town.
Samphire Sauna
South East Hastings, East Sussex · cold dip: sea swim, cold bucket shower or plunge pool
Samphire Sauna sits right on Hastings Pier, one of the most photogenic spots on the south coast and one of very few UK wild saunas on a Victorian pier. Its wood-fired cabins come with a choice of sea swim, cold bucket shower or plunge pool between rounds.
Saunadelic
South East Hove, East Sussex · cold dip: freshwater lagoon plunge
Saunadelic runs a Finnish barrel sauna with a freshwater cold plunge at Hove Lagoon on the Hove seafront. The lagoon setting makes year-round operation more practical than a direct sea plunge in deep winter, and it draws smaller crowds than the better-known Sea Lanes venues to the east.
Seaside Sauna
South East Lancing, West Sussex · cold dip: sea
Seaside Sauna at Lancing is known for its wide half-moon window looking straight out over the sea, extending the Sussex beach-sauna cluster west of Brighton and Hove.
Solent Sauna
South East Lee-on-the-Solent, Hampshire · cold dip: sea
Solent Sauna at Lee-on-the-Solent is an independent, smaller-format operator offering private hire for up to six people and communal sessions in 30 or 60 minute slots. It is the compact alternative to the Southsea and Lepe sites on the same stretch of coast.
Solace Sauna
South East Lepe, Hampshire · cold dip: Solent sea dip or on-site ice bath
Solace Sauna sits directly on the pebbly shoreline at Lepe Beach on the edge of the New Forest, pairing sea views with a choice of a direct Solent dip or an on-site ice bath. The New Forest setting gives it a different character from the urban-beach operators along the Kent and Sussex coasts.
Dulcie
South East Margate, Kent · cold dip: Walpole Bay tidal pool
Dulcie is a community-run, not-for-profit sauna beside the vast tidal pool at Walpole Bay, a short walk east of Margate's main beach. It has a strong local following and a design that nods to Victorian bathing machines, with the tidal pool providing a sheltered cold dip.
Sea Scrub Sauna (Margate)
South East Margate, Kent · cold dip: four whisky-barrel cold plunges (plus the sea)
Sea Scrub Sauna's original Margate site pairs a traditional Nordic wood-fired barrel sauna with the first commercial Saunum Cube sauna in the UK, both with sea views over Margate Main Sands. Cold plunging is via four whisky barrels rather than a direct sea dip, which is useful in winter, and the dual format lets first-timers choose the gentler electric cube while experienced bathers take the hotter wood-fired barrel.
Southsea Seaside Sauna
South East Southsea, Hampshire · cold dip: sea
Southsea Seaside Sauna operates at the Southsea Beach Cafe on the Portsmouth seafront, offering private hire for up to six people alongside communal sessions. The cafe context makes it the easiest Hampshire venue for a casual sauna-and-coffee visit.
Sea Scrub Sauna (Whitstable)
South East Whitstable, Kent · cold dip: two cold-plunge barrels, or a dip off the pebbles
Sea Scrub's Whitstable site is a wood-fired barrel sauna tucked into the working harbour, with a panoramic window over the water and two cold-plunge barrels on site. The harbour and oyster-town character make it the most photogenic of the Sea Scrub locations.
