1. Material Comparison

  • Acrylic: Lightweight and heat-retaining (avg. ¥2,000–8,000), ideal for compact spaces

  • Cast Iron: Classic and durable (weighs up to 300kg), requires reinforced floor support

  • Engineered Stone: Emerging material (starting at ¥15,000), combines aesthetics with antibacterial properties

  1. Smart Upgrades
    Recommended models with temperature control systems (±1°C precision), LED mood lighting (16 million colors), and ultrasonic cleaning (e.g., Kohler Moxie series, approx. ¥23,000).

Scenario-Based Usage Solutions

  • Urban Relaxation: Pair with bath salts (Dead Sea salt + lavender essential oil), soak for 15–20 mins at 38–40°C

  • Family Time: Opt for freestanding tubs with anti-slip textures (e.g., TOTO SW series) and install removable handrails

  • Medical Assistance: Japan’s TOTO CX series features standing aids with a 150kg weight capacity

Maintenance Tips

  • Monthly deep cleaning with a 1:3 white vinegar and baking soda mix prevents soap scum buildup

  • Avoid abrasives on acrylic surfaces; polish scratches with 2000-grit sandpaper

  • For long-term disuse, refill water weekly to prevent seal deterioration
