Buying guide & specifications — Wall Cabinets

Shop frameless RTA wall kitchen cabinets in Ontario in common widths and 12, 15, 18, 21, 24, 30, 36 and 42 in. height options where available. Choose particle-board or plywood box construction with compatible door styles and finishes for standard wall storage, appliance areas and display layouts.

Before choosing upper-cabinet height: measure from the finished floor, confirm ceiling height and planned countertop height, then account for appliance, range-hood and lighting clearances. Taller uppers can increase storage, but the correct height depends on the complete kitchen layout rather than ceiling height alone.

Wall cabinet height guide

Wall Cabinet Height Typical Planning Use What to Verify Before Ordering
12–24 in. Shorter upper cabinets for specific layout, appliance or stacked-cabinet conditions where that exact size is available. Exact cabinet width/height, appliance or hood specifications, adjacent doors and required clearances.
30 in. Standard upper storage where the layout calls for a shorter wall cabinet. Ceiling height, finished-floor reference, countertop height and the planned space above the cabinet.
36 in. Taller upper storage where the room and cabinet layout support the additional height. Ceiling relationship, crown or trim plan, appliance zones and lighting clearances.
42 in. Fuller-height upper storage in layouts designed to use taller wall cabinets. Ceiling height, installation access, trim details and all range-hood or appliance clearances.

These are planning categories, not a substitute for a measured cabinet layout. Exact availability depends on the selected cabinet width, construction, door finish and current product configuration.

How to choose wall cabinet width

Start with the measured wall run and fixed elements such as windows, corners, range hoods and tall cabinets. Current ShopKitchens wall-cabinet listings include widths such as 12, 15, 18 and 21 in. across multiple heights, with additional sizes available elsewhere in the collection. Do not fill the entire measured span with cabinet boxes alone: allow for any required fillers, finished end panels and door clearances so doors can open without contacting walls, adjacent cabinets or appliances.

Wall Cabinet Planning Item Why It Matters Check Before Ordering
Cabinet width Determines how the upper run fits between fixed walls, windows and tall units. Finished wall-to-wall dimensions and the exact product width.
Cabinet height Affects storage capacity and the relationship to the ceiling, countertop and appliances. Finished-floor reference, ceiling height and appliance/hood requirements.
Fillers and end panels Provide planning space at walls and a finished treatment at exposed cabinet ends where required. Which cabinet ends are exposed and where doors need clearance.
Specialty lift cabinets Provide a different opening format for selected upper-cabinet locations. Exact product dimensions, surrounding cabinetry and opening clearance.
