Nobody warned me how many decisions a new kitchen involves.
We settled on our first home four months ago. The kitchen needed a full appliance fit-out. I assumed this would take a weekend of browsing and then some purchases. It took considerably longer and involved several mistakes.
The things I didn't know going in:
rangehood sizing matters more than most guides suggest. It should be wider than your cooktop, not the same width. I bought the same size and had to return it.
oven and cooktop don't have to come from the same brand, but the dimensions need to be checked against your cabinetry before you buy anything, not after.
dishwasher installation involves plumbing, which means if you're buying from somewhere that doesn't understand the trade side, the advice stops at the product and doesn't extend to the install.
We ended up at a showroom on the recommendation of our plumber and found their kitchen appliances range covered everything we needed in one place, plus the people there understood the installation context, not just the spec sheet.
The two-week delivery window that several big retailers quoted us also didn't apply, which mattered because we were working around a tradesperson's schedule.
There's a lot of content online about which brands to buy and not much about the actual process.
