The only appliance we paneled is the DW. With the panel, it looks identical to the trash cab on the other side of the sink cab. Both doors have the same handle/pull as all the other doors/drawers, but for those two doors (and the over the fridge cab) we used the 12" size pull (8" on almost all the rest). The fridge and the stove; KA built-in and Wolf range, are not paneled, and have their own factory-installed handles. IMHO, they all look fine together.

see if you can find that size in the link below. I bought all mine online. the only one with a center support was 60" long. Here is a link that might be useful: long pulls

My experience with using 2 pulls on a wide drawer has not been good. So for this kitchen I will only be using 1 pull per drawer. When you have 2 pulls on a drawer, it takes two hands and often you already have something in one hand. Or, if you just use one of the 2 pulls to open the drawer, it creates stress to the drawer on one side, and also the pull will loosen over time from being asked to pull the entire drawer open from one side. As a result, I am using 1 pull for my drawers. I am using different sizes. Just my taste, but I don't like all one pull size for the entire kitchen. I have read about the 1/3 rule, and the pulls I am choosing, the Top Knobs Princetonians, have many sizes. When deciding between two sizes that both fit roughly the 1/3 rule, I get the smaller one. The wider pulls are expensive, but as a percentage of the cost of my entire reno which is multi-thousands, I am spending about $450 for my pulls. The majority of mine are the 11-11/32" size which are about $13 each. I am getting 4 different sizes in all (includes 2 pulls that are 15" long hung vertically for pull-out pantries). I don't think it's that bad to spend a couple hundred more to get the size that looks good. The pulls really make a difference to how the entire kitchen looks.

Have you priced pulls? Since they must be half overlay doors to allow you to open the doors and drawers it was clearly a budget kitchen.
