{"type":"firestarter.listing","listing":{"id":"lst_RJrB_Nhe","product_name":"Cryospring - Barton Cold Plunge","category":"Cold Plunge","description":"\n\nRotomolded construction for daily outdoor use: Rotational molding produces a seamless, thick-walled shell without joints or seams that can crack under freeze-thaw cycling — built for daily use in both indoor and outdoor environments year-round.\n\nUltra-insulated walls for extended cold retention: Thick insulated walls slow heat transfer from the surrounding environment into the water — the chiller runs less, electricity costs less, and the chiller lifespan extends versus thin-walled alternatives.\n\nLocking child-safety lid: Locks to prevent unsupervised access by children or pets; gasket creates a weatherproof seal that also retains cold between uses.\n\nHidden, protected equipment compartment: Pump, filter, and plumbing components stored in a protected compartment out of view and shielded from weather and accidental damage.\n\nFully modular and serviceable: Individual components — pumps, filters, plumbing fittings — can be removed and replaced by the owner without full tub replacement. Critical for a product used daily over many years.\n\nEpsom salt compatible: Materials, seals, and components chosen to withstand the mineral content of Epsom salt without degradation — not all cold plunges support this without damage.\n","images":["https://cdn.shopify.com/s/files/1/0508/3670/1334/files/The_Barton_3_4_Open.png?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/The_Barton_3_4_Back.png?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/The_Barton_Equipment_Side.png?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/The_Barton_Drain_Side.png?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/The_Barton_Insulation_313a27f3-fc02-43ea-94d5-ac7987c9e0ec.png?v=1780604352","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/The_Barton_Lid_Detail.png?v=1780604353","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG_4818.jpg?v=1780604353"],"price":3999,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:55.617Z"},"share_url":"https://firestarter.network/l/lst_RJrB_Nhe","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
