Normally, the bottom of a kitchen cabinet fits between the sides, usually with a dado in the side panel. I'm going to be supporting my cabinets on a ledger board in the back and adjustable legs on the front. Since the actual carcasses will be simple boxes, I'm seriously considering having the side panels sit on top of the bottom panel. The bottom and sides will be 3/4 inch plywood. My thought is that it will simply be much stronger this way. If the support is under the bottom panel, and there's weight on top (the full cabinets), then I see it as at least POSSIBLE for the weight to cause the bottom panel to push through if it's BETWEEN the side panels.
I know that means the end of the plywood is visible at the bottom of the side panel, but I am going to trim out any exposed ends so they coordinate with the shaker style doors, so the trims would cover that exposed edge.
I don't have a dado blade for my table saw so I'd have to route a dado in each side panel. I'm looking to simplify and speed up construction. I have several carcasses to build ... basically the entire kitchen except for 2 wall cabinets we're reusing.
Still wrestling with frameless vs face frame. It's a "contemporary cottage" theme so if I think "cottage" I think face frames, but if I think "contemporary" then Frameless works fine. Frameless cabinets with shaker style doors (or drawers), Seven and a half foot island, 3 feet wide, with Bamboo plywood for the top, stainless steel range hood over the island, the wall on the "non-working" side of the island is all floor-to-celing pantry cabinets except the last 3 feet is an area we're calling a "coffee bar". Basically it's where the coffee pot will reside but it'll have extra room for serving when we have company. If you're standing at the island and using the cooktop, you'd be facing that pantry wall. Behind you is a 3 foot drawer base, a 36 inch 70/30 stainless steel farmhouse sink that's 10 inches deep, then the dishwasher, then a 36 inch fridge.
Pretty sure I found a source for soapstone slabs for the countertop on that sink run and also for the top of the coffee bar. Cork plank flooring is still what we prefer, but it may get pushed out by something else. Still kinda open on that area as well.
Anyways.... back to the cabinet boxes. Sound like I'm wimping out or sound like I'm planning smart?
