Depends on the grill, the Perfect Flame (Loes brand) I just purchased is held to the base with 4 screws and can be easly converted to a built in.

jbril375, true integrated, not built-in, frigs have no trim, grill or hinges that show when installed. If you put cabinet fronts on the door, then you really cannot tell that the frig is there at all. Most of the time, it is that 1 inch that sticks out of the cabinets versus the true flush look that pushes people to spend the difference. This costs big bucks. I am close to spending alot of money to get this look. I did many hours of research trying to get the frig to be flush without spending the bucks and the hinges cannot be recessed without leaving a big gap between the frig and the adjacent cabinets. I am kicking myself if I really want to do this or not. hidroman, our choices of integrated good looking refrigerator in America is much less than yours in Europe. In my research, integrated frig without top grill/panel led me to Subzero 700, Liebherr, and Siemens/Bosch/Thermador line and Miele. No more. They are all quite expensive! There is a new Jenair line but that still has grill at the top that requires a few inches of opening without a cover. no go for me. All others have grill up top that cannot be disguised or have either trim around doors, stick out 1/2 to 1 inch or so to from the surrouding cabinets. They look like built-in frigs, not integrated cabinetry. I think this is because modern design is much more main stream in Europe and consumers have demanded clean look for many years. For example, American ovens and DW stick out 1/2 inch to 1 inch from the cabinets when installed where as European built in ovens are flush with cabinets. You can do a little trick here or there to make the appliances flush but the initial design elements is not the flush look from the appliance manufacturers. I think the built in frigs are a thing of the past with the popularity of cabinet depth frigs. I think most of the companies will move to integrated look in the next few years. (I may be completely wrong...)

Some sources offered to me the possibility that the Viking trim kit would fit the essentially identical Jenn Air units but I didn't pursue it nor can I confirm it. Electrolux Icon CD shows an optional collar and louver kit in their specs but I haven't seen it displayed. If your main goal is to minimize protrusion, then any refrigerator could be made to appear more flush with either a recessed space behind to allow it to push back further, and/or extended side panels to camoflauge the exposed sides.Trimming out the top gap to fit tighter helps but air flow clearance should still be maintained per spec. Gasket and door still need to be exposed for doorswing clearance. I preferred the look of the Viking so I went with it. I'm hopeful that since it is really the ubiquitous Amana/Whirlpool/Jenn Air CD with a different skin and handle that I had a good chance of reliability and its ratings are of course similar to it's sibling units. It has performed very well.

I need a bit more info and some drawings that show exactly what you are talking about . I think you want to hide the back of the grill is that right ? I would suggest you plan on a builtin grill not free standing then the back can be hidden but I need to see the grill for sure
