Keep your sauna protected in every season with the Replacement Rain Cover – Mk2, designed exclusively for the PortaSauna HEX model. Crafted from high-grade silicone-coated waterproof fabric, this upgraded version offers improved durability, heat resistance, and all-weather protection.

The Mk2 rain cover is built to handle UK conditions — from coastal winds to heavy rain — ensuring your sauna remains dry and secure even when left outdoors for long periods. Its snug fit helps prevent heat loss, protects against moisture damage, and keeps your PortaSauna looking its best.

Perfect if your original cover is worn, misplaced, or simply ready for an upgrade, the Mk2 installs easily and packs down neatly for transport. It’s the ideal companion for semi-permanent garden setups or mobile sauna businesses that use the HEX on the move.

Key Features:
• Custom fit for PortaSauna HEX model only
• Silicone-coated waterproof fabric
• Weather-resistant and heat-resistant
• Quick and easy to install
• Compact for storage and travel

Keep your HEX protected, dry, and always ready for the next session.
