Specs: Shape, Jets, and Build
Shape and footprint
The Intex PureSpa Bubble Deluxe uses an octagonal design with outer dimensions of 71 by 71 inches. This shape offers a distinct corner layout for four people. The SimpleSpa does not list its specific outer dimensions or shape in the provided data. You will need to check the manual for its exact footprint. The octagonal form of the PureSpa may fit differently in your space compared to a standard circular or square model. Consider your available square footage carefully before deciding.
Jet count
Jet count is a clear differentiator between these two models. The PureSpa Bubble Deluxe features 120 bubble jets. The SimpleSpa lists 100 jets in its specifications. Both models utilize heated air bubble technology to circulate water. The PureSpa offers 20 more jets than the SimpleSpa. This higher count may provide more coverage across the seating area. If you prefer a denser bubble experience, the PureSpa has the numerical advantage based on the published specs.
Material and build
Construction materials differ between the two spas. The PureSpa Bubble Deluxe uses Fiber-Tech Beam Construction for structural stability. This technology aims to provide a sturdy frame while keeping the surface comfortable. The SimpleSpa uses Horizontal Beam and Mesh Construction. Its mesh exterior is designed to resist punctures and abrasions. Both methods offer durability, but they achieve it through different material choices. Fiber-Tech focuses on beam stability, while mesh focuses on surface resistance.
Water treatment
Both spas include a built-in Hard Water Treatment System. This feature is present in the PureSpa Bubble Deluxe and the SimpleSpa. It works by making water gentler on skin, clothes, and the spa system. Hard water buildup can limit water flow and reduce spa life. Since both models include this specific system, neither has an advantage here. You get the same protection against mineral buildup in either choice. This is a shared benefit rather than a point of differentiation.
Cover and insulation
The PureSpa Bubble Deluxe includes an energy-efficient spa cover. This cover uses high-density thermal-resistant foam to minimize heat loss. The manufacturer states it can improve energy efficiency by up to 50 percent. The SimpleSpa includes an insulated spa cover and an insulated ground cloth. It does not provide specific efficiency percentages or foam density details. The PureSpa’s cover has more detailed performance claims. This makes it the stronger option for heat retention based on the provided data.
Maintenance access
Maintenance features are listed for the SimpleSpa but not the PureSpa. The SimpleSpa features an integrated control box design for easy filter replacement. It includes two S1 Type filter cartridges. The PureSpa data does not mention filter replacement ease or cartridge type. You may need to consult other sources for PureSpa maintenance details. The SimpleSpa provides clear information on how to access and replace filters. This makes maintenance potentially more straightforward for the SimpleSpa.
Which Intex Spa Fits Your Needs
You want a unique octagonal layout
The PureSpa Bubble Deluxe features an octagonal design with outer dimensions of 71 by 71 inches. This shape provides a distinct corner layout for four people. If you prefer a non-circular footprint that fits specific outdoor spaces, this model offers a practical geometric advantage over standard round designs.
You need more bubble jets
This model includes 120 bubble jets compared to the 100 jets found in the SimpleSpa. The Fiber-Tech beam construction also offers superior structural stability. If you prioritize a higher density of bubbles and a reinforced shell for long-term durability, the PureSpa delivers more intensity and robust support.
You prefer simpler maintenance access
The SimpleSpa features an integrated control box design that simplifies cartridge filter replacement. It includes two easy-to-replace S1 Type filter cartridges. If you value straightforward upkeep and want to swap filters without complex disassembly, this model’s accessible filter system makes routine maintenance quicker and less cumbersome.
