Our Review

The Fisher & Paykel RS3684WICEWATER 20 cu. ft. Built-In is a 19.6 cu. ft. built-in refrigerator from Fisher & Paykel, sitting in the premium ($3,500+) range. With a 13.7 cu. ft. fresh-food compartment and 5.9 cu. ft. of freezer space, it's positioned for couples and small families.

What stands out

Build quality is the headline. Fisher & Paykel 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.

ENERGY STAR Most Efficient certification means it sits in the top ~10% of the category for energy use. At ~457 kWh/year, expect roughly $73 in annual running cost at the U.S. average electricity rate — meaningfully less than older models from a decade ago.

Layout and capacity

Exterior dimensions are 35.8" W × 84.0" H × 24.5" D — check your opening, especially the depth with handles extended. Total useable capacity is 19.6 cu. ft., split 13.7 fresh / 5.9 freezer.

Bottom line

For shoppers who plan to own a fridge for 15+ years and value build quality and design over headline features, the Fisher & Paykel RS3684WICEWATER 20 cu. ft. Built-In earns the premium it asks for.
