What Buyers Are Paying
Strong Spas’ own online store lists the 2021‑25 G‑2B Diamond 28 at an MSRP of $8,699 USD, and no other verified Strong-manufacturer dealer prices for this exact model could be found to establish a broader range, so the best-supported estimate is $8,699 with a narrow bracket at that MSRP.[1]
Dealers never pay to influence scores or rankings.

How much does the Strong G-2B Diamond 28 cost?
Strong does not publish a list price for the G-2B Diamond 28; what you pay is set by your local authorized dealer and the package they bundle with it.
Specs driving that price: 6 seats, 28 jets, 1 pumps, a 74.5"x74.5"x32" footprint. Larger cabinets, more pumps and higher jet counts push both list price and running cost up.
