Build Quality
Both brands use acrylic shells with fiberglass backing. Jacuzzi uses a proprietary ProFinish cabinet, while Master Spas uses DuraMaster Polymer. Both resist fading and moisture damage.
Edge: Tie — Both brands deliver excellent build quality with 5+ year structural warranties.
Jet Systems
This is where the brands diverge most. Jacuzzi's PowerPro jets are widely considered the best in the industry — they deliver targeted, adjustable streams with minimal noise.
Master Spas' StressRelief Neck and Shoulder Seat is a standout feature that Jacuzzi doesn't match. It provides gentle, targeted relief without high-pressure jets.
Edge: Jacuzzi for raw jet performance, Master Spas for neck/shoulder therapy.
Energy Efficiency
Master Spas' EnergyShield insulation system is slightly more efficient than Jacuzzi's SmartSeal system in cold climates. Expect $15-25/month in energy costs for either brand.
Edge: Master Spas (marginally)
