Need help measuring or want a custom size? Email perfectpoolsnz@gmail.com with your spa diameter and we'll confirm compatibility or provide a custom cover quote within 24 hours. You can also visit our contact page.
- Measure across the widest point of your spa shell (not the cabinet)
- Measure in two directions to confirm it is truly circular
- This cover fits 2310mm diameter shells (plus or minus 20mm tolerance)
- If your old cover fits well, measure its diameter and match it
When to Replace Your Spa Cover
- Cover feels heavy and waterlogged (foam has absorbed water)
- Visible cracks, tears, or fading in the vinyl
- Sagging or loss of shape (foam has degraded)
- Increased heating costs (poor insulation)
- Mould or mildew that won't clean off
- Straps or handles are broken or frayed
Average spa cover lifespan: 3-5 years with basic care. This cover is built to last 5-8 years in typical NZ conditions with proper maintenance.

Frequently Asked Questions
Q: How do I know if this cover will fit my spa?
A: Measure your spa shell diameter (should be 2310mm plus or minus 20mm). Always measure the shell, not the cabinet. If unsure, contact us and we'll confirm compatibility before you order.
Q: What spa brands is this compatible with?
A: This 2310mm cover fits large round spa pools including Spa World 2.3m models, Vortex V65/V77, Sapphire 2300mm series, Aqua-Flo 2300mm circular models, and any custom or generic round spa with a 2310mm diameter.
Q: What makes the 6mm vapour barrier better?
A: The vapour barrier wraps the foam inserts and prevents spa steam from penetrating the foam. The industry standard is 3mm - our 6mm barrier lasts significantly longer before the foam starts absorbing moisture and the cover becomes heavy and waterlogged.
Q: Can you make a custom size circular cover?
A: Yes - any diameter and colour. Email perfectpoolsnz@gmail.com with your diameter for a quote within 24 hours.
Q: How much will this save on my power bill?
A: A quality insulated spa cover reduces heat loss by up to 70%, typically saving $200-500/year for an average NZ spa running year-round. This cover pays for itself in 12-18 months.
Q: Is this cover covered by a warranty?
A: Yes, this cover is backed by a manufacturer warranty. For warranty queries, contact us.
