Who should buy which
Pick the Edge Tubs Edge Pro if
Mid-premium buyers who want chillered convenience, sub-Plunge temperatures, and don't need cedar aesthetics or a 5-year-old installed base.
Skip if
You want the largest service network (Plunge), or you want premium aesthetics + 34°F (Renu).
Pick the Inergize Health The Cold Plunge if
Budget-conscious buyers who want chillered convenience but can't justify $9K+ — accept some warranty downside for a 50% discount.
Skip if
You want the longest warranty (Plunge or Renu), or maximum service-network depth.
