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.
Important: Always measure your spa shell diameter before ordering - not the cabinet or surround. Call Danny on 021 023 68881 if you're unsure - we'll confirm the right cover for your specific spa before you spend a cent.
How to Measure Your Round Spa
- 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
Not sure? Call Danny on 021 023 68881 or email perfectpoolsnz@gmail.com - we guide you through the measurement process at no charge.
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 premium 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, call Danny on 021 023 68881 - 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: Can you make a custom size circular cover?
A: Yes - any diameter and colour. Email perfectpoolsnz@gmail.com or call Danny on 021 023 68881 with your diameter for a quote within 24 hours.
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: 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: What are the delivery charges?
A: Door-to-door: Auckland Urban $59 | Auckland Rural $109 | North Island Urban $109 | North Island Rural $199 | South Island Urban $149 | South Island Rural $259.
Mainfreight Depot Collection: North Island $79 | South Island $99.
Free Pickup: 15C Douglas Alexander Parade, Albany, Auckland
Q: Is this cover safe for children and pets?
A: Yes - the 4 locking straps with clips secure the cover firmly. For maximum NZ pool safety compliance, the clips on the included straps provide a secure lock.
Q: How long will this cover last?
A: 5-8 years with proper care, including regular 303 Vinyl Protectant application every 3-4 months.
Q: Do you offer other sizes or colours?
