Shape and Capacity Comparison
Seating Capacity
The Intex 28433EP PureSpa Bubble Deluxe is designed for four people. Its compact size makes it suitable for smaller households or couples. The Intex PureSpa 6 Person Inflatable Hot Tub accommodates six guests. This larger capacity allows you to host more friends or family members simultaneously. If you regularly entertain, the six-person model provides more room. For solo users or pairs, the four-person option offers a cozy fit without excess empty space. Choose based on your typical group size.
Overall Dimensions
The Octagonal model measures 71 inches by 71 inches. This footprint requires a moderate amount of patio or deck space. The 6-Person model is significantly larger at 94 inches by 94 inches. This square layout demands a much wider area for installation. You must ensure your outdoor space can accommodate the larger diameter. The extra width of the six-person tub provides more interior room but takes up more square footage. Verify your available area before deciding which size fits your property best.
Shape and Layout
The 28433EP features an octagonal design with inner dimensions of 51 inches by 51 inches. This shape maximizes corner seating efficiency in a smaller footprint. The 6-Person model uses a traditional square shape with a 94-inch width. The square layout offers uniform seating along the sides. The octagonal design of the four-person tub creates a more intimate gathering space. The square tub provides a more open feeling for larger groups. Your preference for shape will depend on whether you value space efficiency or open seating.
Jet Count
The Intex 28433EP PureSpa Bubble Deluxe includes 120 bubble jets. These jets provide targeted hydrotherapy for the four occupants. The 6-Person model does not list a specific jet count in its published specifications. Both units use Heated Air Bubble Technology for relaxation. The four-person tub explicitly states its jet quantity, allowing you to plan for specific coverage. Without a listed count for the six-person version, you cannot compare the exact intensity or coverage area of the bubbling action directly.
Weight and Portability
The 28433EP Octagonal spa weighs 111 pounds. The larger 6-Person model weighs 130 pounds. Both units are inflatable and relatively lightweight for hot tubs. The four-person tub is slightly lighter, which may make it easier to move during setup or storage. The difference is modest, but the smaller unit is marginally more portable. Consider how often you need to relocate or store the spa. The weight difference is small enough that both are manageable for most users.
Which Intex PureSpa model fits you
Couples or small households with limited space
Choose the 4-person octagonal model if you need a compact footprint. Its 71-inch square dimensions fit tighter patios better than the larger 6-person option. The octagonal shape maximizes seating within these smaller outer dimensions, making it ideal for intimate relaxation without taking up excessive yard space.
Groups of four or more seeking capacity
Select the 6-person model when you regularly host guests. Its 94-inch square base provides significantly more room for six people compared to the 4-person layout. The larger diameter ensures everyone has adequate personal space, making it the practical choice for families or social gatherings who prioritize capacity over compactness.
Users prioritizing structural stability and insulation
Both models use Fiber-Tech construction and energy-efficient covers. However, the 4-person unit offers a denser concentration of features in a smaller volume. The octagonal design with 120 bubble jets provides consistent hydrotherapy coverage across a smaller area, ensuring every seat receives heated air bubbles effectively within the insulated, high-density foam structure.
