It is 32.75 inches wide with doors closed so it should fit in your 33” opening. However, what you need to check is the depth in the opening so that you would be able to open the doors. This fridge is listed at 35” depth and our opening is 24 inches deep and allows for plenty of room for opening the doors. You need to measure height, width and depth then compare to the specs listed for any refrigerators you are considering. Note that this refrigerator also has a bulky hinge for opening the doors at the top of the fridge which obstructs up to about a foot from the front of the fridge at the top. Measure, measure, and measure then measure again.
