Specifications side by side

Spatender Covers at a Glance

These two rectangular foam covers differ primarily by size. The top pick measures 6' x 6', offering a square footprint for smaller tubs. The second option extends to 7' x 6', providing extra length for wider spas. Both models share a cream color and are constructed from durable foam material. This design choice helps reduce heat loss and shields your hard cover from chemical degradation.

You should choose the 6' x 6' model if your hot tub fits a square footprint. It is ideal for owners seeking minimal heat loss and maximum protection. Select the 7' x 6' blanket if you have a rectangular spa that requires additional coverage. This larger size suits those who want to lower energy use while protecting their equipment from damage. Both options serve the same practical purpose for spa maintenance.

Where Spatender Fits Your Needs

Spatender targets owners of rectangular spas with two specific foam blanket sizes. The range starts with the 6' x 6' model, ideal for square tubs. The larger 7' x 6' option suits wider rectangular spas. Both products are cream-colored and made from foam. You get no lighting options or varied shapes in this lineup. The brand does not offer covers for round or irregularly shaped hot tubs. If your spa is not rectangular, this brand likely lacks a suitable fit. Stick to these two dimensions for proper coverage.

How to choose the right spa cover

1. Match your tub dimensions

   Start by measuring the exact outer dimensions of your hot tub shell. The Spatender 6' x 6' model fits square tubs with a 72-inch width and length. If your spa is rectangular and wider, the 7' x 6' option provides an 84-inch length. Choosing the correct size ensures full coverage. Gaps allow heat to escape and reduce insulation efficiency. Verify your tub's footprint matches the blanket's specified length and width before purchasing.

2. Check material composition

   Both available Spatender models are constructed from foam. This material provides thermal insulation to retain heat in your spa water. Foam also acts as a barrier against chemical damage for your existing hard cover. The cream color is consistent across the range. You should verify that the foam density meets your needs for durability. The material choice directly impacts how well the blanket floats and insulates your spa.

3. Select the correct shape

   Spatender offers only rectangular shapes for these foam blankets. The 6' x 6' model creates a square footprint, suitable for square spas. The 7' x 6' model extends the length to accommodate wider rectangular tubs. Do not attempt to use these on round or irregularly shaped spas. The rectangular design ensures the blanket lies flat on the water surface. Confirm your spa shape aligns with one of these two rectangular dimensions for proper fit.

4. Verify usage compatibility

   These products are designed specifically for spas and hot tubs. The attributes list them as pool covers, but the intended use is spas. They float on the water surface to reduce evaporation and heat loss. Ensure your tub is a standard spa size that matches the blanket dimensions. They are not suitable for swimming pools or large commercial jets. The foam construction is optimized for residential spa environments to maintain water temperature effectively.

5. Consider model year updates

   Spatender lists specific model years for these covers, such as 2021 or tc-2. These identifiers may indicate design revisions or manufacturing batches. While the core specs remain similar, checking the model number ensures you receive the latest version. The 6' x 6' model is listed as 2021, while the 7' x 6' is tc-2. This detail helps you track inventory or replacements. Always verify the model number matches your current setup requirements for compatibility.
