Which one should you choose?
Choose The Cover Guy 8x8 ft Square Replacement Spa Cover if
- You need a rigid cover that supports weight and meets ASTM safety standards for load bearing.
- You want a custom-made fit for an 8' x 8' square hot tub with high insulation ratings.

Choose Spatender 6' x 6' Foam Floating Spa Blanket if
- You want a lightweight blanket that floats on the water to reduce heat loss from evaporation.
- You need a smaller 6' x 6' cover to protect your hard cover from chemical damage and debris.

Verdict: Choose The Cover Guy if you require a durable, structural replacement cover with high insulation and safety features for a larger square tub.

Covers Compared by Specs
Insulation value
The Cover Guy lists an insulation rating of R19. This metric indicates how well the material resists heat flow. A higher number means better thermal retention for your hot tub. Spatender does not provide an R-value in its published specifications. Without this data point, you cannot directly compare the thermal efficiency of the floating blanket against the rigid cover. The Cover Guy’s rating gives you a clear benchmark for energy savings, while Spatender’s lack of an R-value leaves the insulation performance open to interpretation based on other factors.
Material composition
The Cover Guy uses marine-grade vinyl as its shell material. This exterior layer is designed to withstand outdoor elements and resist water absorption. Inside, it utilizes medium-density foam, with an option to upgrade to high-density foam. Spatender is constructed entirely from closed-cell foam. This material floats on the water surface rather than sitting on top of a hard cover. Marine-grade vinyl offers a durable, weather-resistant barrier, whereas the closed-cell foam provides buoyancy and direct surface insulation. The structural difference defines how each product interacts with your spa environment.
Cover thickness
Thickness plays a role in both durability and insulation. The Cover Guy offers options of 6, 5, or 4-inch taper thicknesses. This substantial build supports load-bearing thresholds and enhances thermal resistance. Spatender is significantly thinner at just 3/8 inch. This slim profile allows it to float directly on the water. The thicker rigid cover provides a solid barrier against snow and debris. The thin foam blanket is designed to be lightweight and easy to remove. You choose between a heavy-duty barrier or a minimal surface layer.
Fit and dimensions
The Cover Guy is custom-made to fit specific dimensions you provide. It comes in an 8x8 ft square size, with a tolerance of plus or minus 0.5 inches. This ensures a snug fit for larger spas. Spatender is a fixed 6x6 ft rectangular blanket. It is designed to fit most hot tubs of a certain size range but is not custom-cut. If your spa is larger than 6x6 ft, the Spatender will not cover the entire surface. The custom sizing of The Cover Guy offers precise coverage for larger or non-standard tubs.
Fastening method
Securing your cover is important for safety and stability. The Cover Guy uses straps with a locking feature. This mechanical fastening system keeps the rigid cover firmly in place during wind or heavy snow. Spatender has no listed fastening mechanism. As a floating blanket, it relies on its position on the water surface. It does not attach to the spa shell. This means it may shift or move if the water is disturbed. The locking straps of The Cover Guy provide a more secure and stable installation for outdoor use.
Choose the right spa cover for you
You want a rigid, insulated replacement cover
The Cover Guy provides a structural replacement with an R19 insulation rating. Its marine-grade vinyl shell and zero water absorption technology prevent heat loss and waterlogging. The locking straps and durable foam core offer a secure, long-term solution for your 8x8 foot spa. This rigid design keeps debris out and retains warmth effectively.
You need a floating thermal blanket
Spatender offers a 6x6 foot floating blanket made from closed-cell foam. It sits directly on the water surface to reduce evaporation and heat loss. This lightweight option protects your existing hard cover from chemical damage. It is easy to trim and fits smaller spas, providing a simple layer of thermal insulation.
You prioritize energy savings and durability
The high-density foam and R19 rating of The Cover Guy are designed to significantly reduce heating costs. The custom-made fit and reinforced straps ensure the cover stays in place. With a three-year warranty and zero water absorption technology, this product is built to withstand weather and maintain its insulating properties over time.

Frequently asked questions
Which cover is better for an 8x8 hot tub?
The Cover Guy 8x8 Square Spa Cover is the correct choice for large square tubs. It measures 96.1 inches on each side, fitting your spa dimensions precisely. Spatender only offers a 6x6 size, which is too small for an 8x8 tub. You need the larger footprint for proper coverage and heat retention.
Does Spatender provide an R-value rating?
No, the Spatender 6x6 Foam Floating Spa Blanket does not list an R-value in its published specifications. The Cover Guy explicitly states an R19 insulation rating. This metric shows how well the material resists heat flow. Without an R-value, you cannot directly compare the thermal efficiency of the Spatender foam sheet.
What material is the Spatender cover made of?
The Spatender 6x6 blanket is made of foam. It is a simple foam sheet designed to float on the water surface. This material helps stop evaporation and protects your main cover from chemicals. The Cover Guy uses a different construction with marine-grade vinyl and foam, offering a more rigid structure.
How heavy is the Cover Guy replacement cover?
The Cover Guy 8x8 Square Spa Cover weighs 45 pounds. This weight contributes to its stability and durability. Heavier covers often indicate denser insulation materials. Spatender does not list a weight for its foam blanket, so you cannot compare the mass or structural density of the two products.
Can I use Spatender for a hot tub larger than 6 feet?
No, the Spatender 6x6 Foam Floating Spa Blanket is designed for square spas up to 6 feet wide. Its dimensions are 72 inches by 72 inches. If your tub is larger, this blanket will not provide full coverage. You would need the larger Cover Guy option or a different sized blanket.
What color options are available for these covers?
The Cover Guy 8x8 cover is available in brown. The Spatender 6x6 blanket comes in cream. Color choice is a cosmetic detail that does not affect performance. Both colors are standard for spa covers. You should choose based on your preference for how the cover looks on your patio or deck.
Is the Cover Guy cover waterproof?
Yes, the Cover Guy 8x8 Square Spa Cover is described as waterproof with zero water absorption technology. This feature prevents heat loss and stops the cover from becoming waterlogged. Spatender is a foam blanket that floats, so it interacts with water differently. The rigid vinyl construction of the Cover Guy ensures it stays dry.
Which product is better for energy savings?
The Cover Guy 8x8 Square Spa Cover is listed as energy-saving with an R19 rating. This high insulation value helps retain heat in your hot tub. Spatender is a foam blanket that reduces evaporation, which also saves energy. However, the explicit R19 rating of the Cover Guy provides a measurable metric for thermal efficiency.
