  • Pro: “The most consistent 40°C I’ve ever felt. No cold back, no overheating feet.” (User HotSpringDad, 2013)

Body & Material

  • FRP (Fiber-Reinforced Plastic) with a tensei (smooth, ageless) coating. Not the cheap acrylic of 2000s mass-market baths. The 2011 model uses a 4-layer composite: colored gel coat, high-density FRP, rigid polyurethane foam insulation, and an inner onyx finish that resists scratching from mineral deposits.
  • Color: Most units were “Mizu-iro 28” (a pale, milky blue-green) or “Shiro-aka” (white with faint pink undertones to mimic oxidized spring deposits).
