Which is better for a family of six?

The American Spas tub. It has six seats and a 425-gallon shell. The Miami is rated for two to four adults.

Is the American Spas tub worth the extra money?

Yes if you keep it for years in a cold climate. The 5.5 kW heater, insulation and ozonator cost far less to run than an inflatable. The Miami wins if you want low upfront cost or may move.

The acrylic spa. A rigid shell on a treated frame typically outlasts an inflatable vinyl tub, which can puncture or lose shape over seasons.

Can I use the Miami in winter?

Only mildly. Freeze Shield protects the pump, but the 3-4 F per hour heat rate struggles in hard freezes. The American Spas tub holds 104 F with its 5.5 kW heater.

What does each need for power?

The American Spas tub needs a dedicated 240 V, 50 A circuit. The Miami runs on a standard 120 V outlet.

How much does each weigh filled?

The Miami weighs about 1,534 lb filled. The American Spas tub holds 425 gallons, so expect well over 4,000 lb with water and bathers; check your deck rating.
