What does your independent kitchen designer recommend for your budget and skill level? There’s a huge difference in 1 year warranty junk RTA stock cabinets and a lifetime warranty highly customizable line. Either needs a large amount of tools and experience to truly DIY. Boxes have 6 sides to get level, plumb, and coplanar.

we installed the original cabinets we have a master craftsman in the family ,skill and tools are in order . Originals are plywood boxes ,wood frame doors all stock cabinets actually in good shape , but I would like to update some features .Are any stock cabinets a decent quality ?

Nope. None will ever satisfy anyone who uses the term master craftsman. They will all fall short. Of course, if that person doesn’t understand that composite materials are far better and more desirable than crappy bad import plywood, then nothing will work for that dinosaur but to make their own.

sorry

@golfer50043 - the poster Verbo habitually posts on here that people must only work with "independent kitchen designers" (i.e. $$$) and the very best materials on the planet. It's fine that is her viewpoint and perspective, but is unrealistic for many. In your situation I recommend Ikea cabinets. Sometimes an Ikea kitchen can be difficult for people who have never put cabinets together, but you do not have that issue. Ikea has a design software for you to use to layout your kitchen cabinet design.

Note that for all decent cabinetry, there are long lead times due to the supply chain issues. In any case, I advise you to post your kitchen design/layout on this forum before purchasing any cabinetry. There are some really skilled people on this forum who can give advice whether your layout is good or needs improvement.
