Break-in forces closure of seaside sauna after glass found in plunge pools

Broken glass in the plunge pools forced Sea Scrub Sauna’s Folkestone site to shut its doors, turning a seaside wellness destination into a cleanup job overnight. The break-in left shards scattered across the harbour-side venue, creating an immediate risk for visitors and staff barefoot between the sauna, hot tub and cold water.

Co-owner Robin Bartlett said safety had to come first, and the business closed temporarily while the glass was cleared. The site reopened the following day after the issue was addressed, but the incident underlined how fragile shared cold-plunge spaces can be when they sit in open, public-facing locations like Folkestone Harbour Arm. Harbour-arm security also stepped up patrols after the break-in.

Sea Scrub Sauna has spent the past year pushing hard to establish the Folkestone branch as its flagship. The company describes the site as its largest and most ambitious location and calls it the UK’s biggest beach spa. Built on the seafront, it includes two wood-fired saunas, a communal cold plunge tank, a hot tub, warm showers and a café serving a Japanese lunch menu.

The Folkestone opening also matters to the Bartlett family’s wider rollout. Sea Scrub Sauna is run by cousins Luke Bartlett and Robin Bartlett, and Folkestone is the fourth branch in Kent after Margate, Whitstable and Faversham. Local coverage said the new custom-built sauna was due to open in March 2026, before later reporting put the opening on Saturday 14 March 2026.

The business has been positioning itself around a broader shift in British sauna culture, toward more communal, “wild” experiences rather than exclusive spa visits. That makes the glass incident more than a nuisance: it hit a venue built on openness, foot traffic and trust, exactly the qualities that draw people to a beach spa in the first place. When a plunge pool has to be checked for shards before anyone can step in, the appeal of the cold-water ritual depends as much on security and maintenance as it does on heat and chill.
