The Solent Sauna is an independent seafront sauna on the beach path at Lee-on-the-Solent, across the harbour from Portsmouth. Single seats in communal sessions cost £9 for 30 minutes or £18 for an hour, and the whole sauna can be hired privately for up to six people for £90. Guided 90-minute sessions add aromatic steam, herbal infusions, whisking and scrubs, and the sea is close by for cooling. From October 2026 to March 2027 it opens Friday to Sunday.
