Yes. I am building a house and will have a Bosch Dishwasher and range but an LG refrigerator. In my last house I had a Whirlpool refrigerator, Samsung range, and another brand dishwasher. No one said anything about my appliances not being the same brand. They actually helped sell the house!

Looking to do the exact same appliances in my new kitchen with the Advantium instead of microwave.

Having all the appliances be of the same brand is a personal preference. Half my customers care about that when planning, half don't care. If/when I mix brands to keep within a budget or work with existing appliances, I take extra attention to the handle bars and badging. Sure it's all stainless steel, but those nuances a more discerning eye would notice if trying to "match" while mixing it up.

Exactly. Handles should be a similar style, or in the case of a dishwasher, easy to hide any brand with a cabinet panel.

Did you end up doing this? How did it look?
