What Buyers Are Paying
range $7,900 – $12,999
Two independent Harmonic dealers publish prices for the exact H28RB model from harmonichottubs.com, with one listing a price of $7,900 and another listing a “starting at” price of $12,999, so the midpoint and range are directly bracketed by real dealer pricing.
Dealers never pay to influence scores or rankings.
