We're looking at blogs discussing install without plinth/toe kick to bring base cabinets to desk height. Flooring is vinyl plank. There will be butcher block installed as desk surface.

A contractor will be helping, but he has not done Ikea cabinets anywhere but kitchen. Ikea has ordering sheets to place order without the toe kicks and support feet. Just want to know if I should be planning to put cabinets on ply supports or such for clearance of drawers/doors, or inherent support.

edit to add I am planning on several floor cabinets that are 24" deep. We want the cabinet and counter to be as close to "normal" desk height as possible.

given 30" cab, a ply base and countertop surface we're at 32" tall. I believe anchoring them on steel rails on wall to be best idea thus far.

edit to add I just hired an Ikea virtual designer to figure this out. I will share results later promise
