Our Review
The Thermador T42BT120NS 23 cu. ft. Built-In is a 23.1 cu. ft. built-in refrigerator from Thermador, sitting in the premium ($3,500+) range. With a 16.2 cu. ft. fresh-food compartment and 6.9 cu. ft. of freezer space, it's positioned for families of 4-5.
What stands out
Build quality is the headline. Thermador models use metal drawer rails, soft-close hinges, and consistent interior LED lighting that you don't get in the mainstream tier. Door seals are noticeably more substantial — a small detail that translates to better long-term temperature stability.
Layout and capacity
Exterior dimensions are 42.0" W × 84.0" H × 24.5" D — check your opening, especially the depth with handles extended. Total useable capacity is 23.1 cu. ft., split 16.2 fresh / 6.9 freezer.
Bottom line
For shoppers who plan to own a fridge for 15+ years and value build quality and design over headline features, the Thermador T42BT120NS 23 cu. ft. Built-In earns the premium it asks for.
