Spa Cover FAQ: Measuring, Foam Options & Long-Term Care
How Do I Prevent My New Spa Cover From Fading or Cracking?
Sun exposure is the #1 cause of vinyl fading and cracking.
With proper care, your spa cover should not crack during the warranty period. Regular cleaning and applying 303 Aerospace Protectant every other month can dramatically extend its life.
-
With no maintenance: 4–6 years typical lifespan
-
With regular cleaning + protectant: many customers report 8–10 years
Maintenance makes a major difference.
How Do I Measure My Spa Cover?
If you know the make, model, and year (year manufactured — not purchased), we can compare factory specifications with your measurements.
Important:
-
Manufacturers sometimes change dimensions mid-year.
-
Brochures often round measurements to the nearest inch.
-
Brochures do NOT list corner radius or cut-corner dimensions.

If you’re in Orange County or LA County, we can measure it for you.
What Is the Skirt and What Does It Do?
The skirt hangs down around the outside edge of the spa.
It:
-
Protects exposed fiberglass from UV rays
-
Improves appearance
It does not create the insulation seal.
The seal comes from the foam core and the fit.
Understanding Foam Options
Choosing the right foam depends on climate, usage, and spa type.
Standard Foam
1.0 lb density – 4″ to 2″ taper
Best for:
-
Southern California
-
Moderate climates
-
Typical above-ground spas
Lightweight and cost-effective.
Deluxe Foam
1.5 lb density – 4″ to 2″ taper
-
More insulation than Standard
-
Good middle-ground option
-
Often used by manufacturers nationwide
Offers improved strength without heavy weight.
Heavy-Duty Foam
2.0 lb density – 4″ to 2″ taper
Recommended for:
-
Any snow load
-
Temperatures below 50°F
-
Higher wind exposure
Higher density = better insulation + stronger core.
All in-ground spa covers use Heavy Duty or Super Foam by default.
Super Foam
2.0 lb density – 5″ to 3″ taper
-
25% thicker than standard
-
Stronger structural support
-
Better for built-in spas or heavy load situations
Keep in mind:
Thicker covers are heavier. If you remove your cover manually, weight matters.
Is a Thicker Cover Always Better?
Not necessarily.
The most important factors are:
-
Foam density
-
Proper taper
-
Build quality
A heavier cover that isn’t constructed properly may sag, absorb water, or tear over time.
Choose the cover based on your climate, usage, and lifting method — not just thickness.
Final Advice
