Kestly Insulated Plunge Lid — Universal Cold Plunge Cover (80–90cm)

An insulated cover designed to sit over 80–90cm cold plunge tubs, slowing temperature rise between sessions and reducing ice consumption.

Every hour an uncovered tub sits open, ambient heat works against you — particularly in summer or in heated indoor spaces. A well-fitted insulated lid can meaningfully extend how long your water holds temperature, reducing how often you need to top up ice or run a chiller. This lid is sized to fit the most common UK plunge tub diameters in that range, including barrel-style and oval tubs.

What it does

• Insulated construction slows ambient heat transfer into the water between sessions
• Universal fit supports 80–90cm internal diameter plunge tubs
• Lightweight enough to lift and set aside single-handed before entry
• Helps reduce ice top-up frequency and chiller running time

Who it's for

Cold plunge users who want to protect their water temperature investment between daily or twice-daily sessions. Particularly useful for those without a chiller unit who rely on ice, and for anyone positioning their tub outdoors or in an unheated space.
