6x6 Indoor Walk-In Coolers

Yes. The same insulated panel construction used for 6x6 coolers can be configured for freezer-temperature duty by upgrading to freezer-rated doors with anti-condensate heat wire and R32 PC20 rigid foam cores, plus a freezer-rated refrigeration package. ELT Custom Coolers builds dual-use boxes that support both cooler and freezer configurations.

Prehung replacement doors with plug or jamb frames typically install in about an hour, dropping directly into the existing wall panel opening without on-site fabrication. Sliding door systems with track, trolley, and header assemblies take longer—generally 2 to 4 hours—due to the additional hardware installation involved.

Options include prehung swing doors with plug or jamb frames, sliding doors with jamb sandwich frames and headers (including electric-powered sliding for high-cycle use), and fully custom doors for odd-shaped or oversize openings. Standard swing door widths range from 30" to 60" and heights from 78" to 130".

Pricing depends on box construction, door style, and refrigeration package. Prehung replacement doors start around $1,450, sliding door systems start near $2,800, and complete walk-in boxes with door (comparable footprints like 8x8x8) run roughly $7,800–$9,800. Custom quotes are typically provided within one business day based on exact specifications.

Look for NSF-approved hardware and accessories to ensure food-safe, sanitary contact surfaces, along with UL certification for electrical components and DOE 2017 compliance confirming the unit meets current U.S. Department of Energy efficiency standards for commercial refrigeration equipment. These certifications indicate the cooler meets recognized safety and performance benchmarks.

Yes. Custom cooler doors and boxes can be built for oversize, odd-shaped, or space-constrained openings, with quotes typically provided within one business day after submitting photos and measurements. Plug frame and jamb frame options also allow retrofitting into existing openings without major structural modification.
