Most kitchens have multiple brands in them. Don't worry about matching brand so much as making sure you're getting good products. It's a good idea to match color, but matching brand will likely land you with at least one product you'll be unhappy with.

If you haven't yet, look at induction for your cooktop. Best performance and easy cleanup. Bosch is a good option.

All stainless will look fine from any brand. Mix away.. Don't be in a twist over nothing. You buy appliances to suit the size and function and budget and stainless is timeless from ALL mfgs.

Where did you get the idea the brand match is a thing?

Not a single appliance in my kitchen is the same brand. I have Blue Star, Bosch, Vent-a-Hood, LG, and Electrolux. All stainless and work fine together.

I am in the same dilemma. I recently purchased a new stainless steel dishwasher but there is no branding on the exterior as I thought it would match better with whatever brand range and refrigerator I purchased.

All plain old stainless and you buy appliances for how they function for you not all from the same maker. BTW there is no maker that makes everything well and honestly it really does not matter if the branding is there somewhere., function is the 1 st priority in any kitchen

match the color/finish and buy the best appliance you can afford for each purpose

And no, it does not need to be stainless, unless that's what you want. All black or all white can work fine, too (though make sure they're the same white). Our kitchen has several different brands all in black, and it works just fine.

If you are hoping that there is some secret design rule book somewhere which will tell you that it is okay to mismatch the cooktop or the mismatch the fridge, rest assured that there is no such rule book. FWIW, this same question has come up every few weeks over the decades I've been following this forum. The answers have almost always been what you see above. The few exceptions have been: (a) people who want their kitchens to look staged for a magazine shoot or advertisement; or (b) those with a personal aesthetic that absolutely requires a specific look. Numbers of the latter have come back over the years to complain that their matching appliances did not match well enough to meet their personal standards for matching. If you are worried about resale values, be reassured. The advice here has always been that shoppers who fixate on everything matching to the nth degree are just a small part of the market who are probably planning to gut any kitchen as soon as they buy the place, anyway. ;>)

Im one of those people who have to match. I can deal for the short term but when we built i even made sure my washer and dryer were same brand and finish.
