Round Inflatable Spa Cover 145cm

Exact diameter: 145 cm. Tailored for round-shaped inflatable and hard-shell spas commonly sold in the UK market. Material: High-frequency welded PVC with UV-stabilised outer layer to resist fading and cracking under prolonged sun exposure. Includes integrated one-way inflation valve for quick, leak-resistant filling and controlled deflation. Weight: under 1.2 kg — lightweight enough for one-person handling but structurally stable once inflated. Functions as both thermal lid and environmental shield: significantly reduces overnight heat loss (measured at ~30–40% less temperature decline vs uncovered), suppresses algae-promoting evaporation, and blocks falling leaves, pollen and light precipitation. Maintains optimal water temperature longer between uses — meaning fewer top-ups and less chemical imbalance caused by evaporation. Suited to year-round use: enhances efficiency in summer by limiting solar overheating drift, and delivers clear value in autumn/winter by preserving heat after each session. Works equally well on timber decks, concrete patios, grassy areas or gravel — no anchoring or surface modification required.
