Classic Series (BI) vs. Designer Series (IT, IC) Comparison


  • What is the difference between a Classic (BI) unit and a Designer (IT, IC) unit?
  • Selling point differences between Classic vs Designer models
  • Selling features of Classic vs Designer models
  • Designer versus Classic differences


The key differences between the Designer (IT, IC) and the Classic (BI) lines are as follows:

  • Designer models have a more "seamless" look than Classic models. In other words, Designer units show less metal.
      • The Designer line is more of a "cabinet" look. Designer units blend seamlessly into the kitchen.
      • Designers typically select models from the Designer line, as the Designer look helps create a seamless kitchen.
    • With Classic models, the presence of the refrigerator in the kitchen is more apparent.
      • The Classic line expands on the traditional look that Sub-Zero has had for decades.
    • If the unit will be freestanding, or the sides of the refrigerator will be partially exposed, Sub-Zero recommends the Classic line.
    • To visually compare different models, refer to the Sub-Zero Refrigeration Product Page.
