Spa Construction
Bullfrog Spas’ exclusive UniSystem™ structural design is the future of advanced-spa
engineering providing world-class spa construction with superior strength and durability.
1 - UniBase™
A great foundation is the basis for the best-designed and weather-proof spas. Our molded ABS base provides remarkable noise reduction, anti-vibration control, three convenient electrical chaseways, and a retractable exterior drain. The synthetic materials yield greater longevity compared to wood.
2 - UniFrame™
Bullfrog’s injection-molded Z-Beam components connect the base, shell and cabinet to form an integrated framing structure with unmatched precision and strength. The UniFrame design ensures consistency in the manufacturing process and, along with the UniBase, delivers a superior foundation.
3 - UniColumn™
We add foundation supports under high-usage areas to strengthen overall spa integrity. This process greatly improves the structure of the footwell and seating areas of the spa.
4 - UniShell™
Our shell incorporates a bonded three-layer system for added strength and stability. We co-extrude a UV-stabilized acrylic surface to a layer of impact-resistant ABS. Isotec® high-density rigidizer is then applied enabling the shell to withstand the effects of time.
5 - EternaWood™ Cabinet
We use weather- and UV-resistant materials that are textured with a wood-grain pattern to offer years of maintenance-free enjoyment.
