Is This Cover Compatible With Your Spa?
This cover is designed for any round/circular spa pool with a 1800mm diameter shell. Round spa pools are less common than square or rectangular models but are found across several NZ brands. Always measure your spa shell diameter before ordering, not the cabinet or surround.
Important: Always measure your spa shell diameter before ordering, not the cabinet or surround. Not sure? Contact us and we'll confirm the right cover for your specific spa before you spend a cent.
How to Measure Your Round Spa
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 1800mm 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 1800mm plus or minus 20mm). Always measure the shell, not the cabinet. If unsure, contact us and we'll confirm compatibility before you order.
Q: Are the clips and straps included?
A: Yes - 4 heavy-duty locking straps with clips are included. Everything you need to secure the cover is in the box.
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.
