Installing kitchen cabinets is one of the highest-impact DIY projects a GTA homeowner can tackle — and one of the most unforgiving. Cabinets that are out of level or not properly secured to studs cause problems that compound through the entire kitchen build: doors that won't close, drawer fronts that don't align, countertops that rock. Done correctly, a DIY cabinet installation saves $1,500–$4,000 in labour costs on top of the material savings from choosing IKEA SEKTION over a custom shop. This guide walks through the full process — layout through final adjustment — in the correct sequence.
Before you start: nail down your total budget. Our kitchen renovation cost guide for the GTA breaks down what GTA homeowners spend on cabinets, countertops, appliances, and labour in 2026. For where to buy materials, see our top home improvement stores in Toronto comparison.
2026 GTA Cabinet Pricing: What to Expect
Cabinet costs in the GTA in 2026 break into three distinct tiers — and the differences between them are significant enough to shape the entire kitchen budget. All prices below are for a typical GTA kitchen (roughly 10 linear feet of upper and lower cabinets, not including countertops, hardware, or installation labour unless noted).
| Cabinet Type | Typical Range (CAD) | Where to Buy |
|---|---|---|
| IKEA SEKTION (RTA flat-pack) | $3,000–$8,000 | IKEA Etobicoke, North York, Burlington |
| Home Depot Hampton Bay (semi-custom) | $8,000–$15,000 | Home Depot GTA locations |
| Local GTA cabinet shop (custom) | $20,000–$50,000 | Custom shop — 6–12 week lead time |
| Upper cabinet hinge hardware | $5–$10 per hinge | Home Depot, RONA, Lee Valley |
| Full-extension drawer slides (per pair) | $25–$50 | Home Depot, Lee Valley, Amazon.ca |
| Professional installation (labour only) | $1,500–$4,000 | GTA kitchen contractors |
💡 IKEA Kitchen Event — Plan Around It
IKEA runs kitchen sales events (typically 15–20% off cabinets) in January, March, and September. If you're not on a tight timeline, planning your purchase around an IKEA kitchen event can save $400–$1,200 on a typical SEKTION kitchen. Sign up for IKEA emails to get advance notice — these events sell out popular door styles.

Step-by-Step: Installing Kitchen Cabinets
Find Studs and Mark Your Layout
Run a stud finder along every wall where cabinets will mount. Mark each stud clearly with painter's tape from floor to ceiling — you'll need to reference these marks throughout the install. Standard GTA stud spacing is 16 inches on centre, but older homes (pre-1970) often have irregular spacing. Verify every stud by test-drilling a small hole at an inconspicuous spot. Once studs are confirmed, use a level to draw a horizontal reference line at your upper cabinet height (typically 54 inches from the floor for standard 30-inch upper cabinets with an 18-inch gap above the counter). Draw a second line for the top of your base cabinets (34.5 inches from the floor, to accept a standard 1.5-inch countertop at 36 inches).
Install the Temporary Ledger Board
This is the most important preparation step — and the one most DIYers skip. Cut a straight 1×3 or 1×4 board to the length of your upper cabinet run. Screw it into studs along the line you drew for the bottom of the upper cabinets. This ledger holds the weight of each upper cabinet while you get it positioned and screwed into the wall, freeing both hands. Without a ledger, you're holding a 30–50 lb box against the wall with one hand while driving screws with the other — a recipe for a crooked install or a dropped cabinet. The ledger is removed after all uppers are secured.
Hang Upper Cabinets First
Always install uppers before lowers — with no base cabinets in the way, you have room to stand at the wall, position the unit on the ledger, and drive screws comfortably. Start from a corner cabinet or the most visible end of the run. Rest the first cabinet on the ledger, check level side-to-side and front-to-back, and drive 3-inch screws through the cabinet's hanging rail and into the studs. Every cabinet needs a minimum of 2 screws into solid framing — not just drywall. Clamp adjacent cabinets together with panel clamps or C-clamps before joining them with connector screws — this keeps the face frames flush before the cabinets are permanently attached to each other.
Install Base Cabinets
Find the highest point of your floor using a long level or laser level — base cabinets are referenced from this high point so they're all at the same height. Start with a corner base cabinet, shim to level in both directions, and screw into studs through the cabinet's back rail. Work outward from the corner, clamping and joining each unit as you go. Check level and plumb constantly — an error in the first cabinet multiplies through the run. Base cabinets should be screwed to the wall (into studs) and to each other (through the side panels).
Add Fillers and Trim
Where the cabinet run meets a wall, there will almost always be a gap — walls are rarely perfectly square and cabinets come in fixed sizes. Filler strips (strips of matching cabinet material, typically 1.5–3 inches wide) fill this gap. Scribe the filler to the wall profile if the gap varies: hold the filler strip against the wall, set a compass to the widest gap, and run it along the wall to trace the contour. Cut along the scribed line with a jigsaw and the filler will sit flush against even irregular walls. After fillers, add crown moulding on uppers and light rail if applicable.
Hang Doors, Install Drawer Fronts, and Adjust
Install doors last — it's much easier to work inside cabinets without doors in the way. European-style soft-close hinges (standard on IKEA and most semi-custom) have 3-way adjustment: height (up/down), side (left/right), and depth (in/out). Use all three to get doors perfectly aligned — gaps should be uniform across the entire run. Drawer fronts attach with machine screws from inside the drawer box — use spacers to hold the front in position while you drive the screws. Adjust until reveals are even. Install pulls last using a pull-drilling jig ($15–$30 at Lee Valley) to ensure consistent placement.
⚠️ Never Rely on Drywall Anchors for Upper Cabinets
Upper kitchen cabinets loaded with dishes and pantry items can weigh 150–300 lbs per run. Drywall anchors — even heavy-duty toggle bolts — are not rated for this load in combination with a lever arm. Every single cabinet must have screws going into framing. If a stud doesn't land where you need it, add a backer board (a horizontal 2×6 lag-bolted between two studs) before hanging cabinets. This is a code and safety issue, not a preference.

Frequently Asked Questions: Kitchen Cabinet Installation
❓ Do I need studs for upper kitchen cabinets?
Yes — every upper cabinet must be screwed into wall studs. Minimum 2 screws per cabinet into solid framing. Drywall anchors alone will fail under the weight of a loaded kitchen cabinet. Use a stud finder and verify with a test drill before hanging anything.
❓ How do I level cabinets on an uneven floor?
Find the highest floor point first — this becomes your reference height. Shim base cabinets up at low points to reach that height. The toe kick trim covers all shimming. Never cut down a cabinet to match a low spot in the floor — that makes cabinets shorter than standard countertop height.
❓ IKEA SEKTION vs semi-custom vs custom — what's the right choice?
IKEA SEKTION at $3,000–$8,000 is excellent value for standard layouts. Hampton Bay semi-custom at $8,000–$15,000 offers more door styles and slightly better build quality. Local GTA custom shops at $20,000–$50,000 are for non-standard kitchens, premium finishes, or specific design requirements. Most GTA homeowners get excellent results from IKEA or semi-custom with good planning.
❓ Should I install cabinets before or after flooring?
Install cabinets before flooring. Base cabinets sit on the subfloor. Finished flooring runs up to — not under — the cabinet bases. This saves material and makes future cabinet removal easier. Floating floors (LVP, laminate) must never go under cabinets — they need room to expand.
❓ How do I cut around electrical outlets in the cabinet run?
Mark the outlet location on the cabinet back panel before positioning the unit. Cut with a jigsaw. If the outlet sits inside the cabinet run, use an electrical box extender ring ($5–$15) to bring the face flush. Any outlet relocation requiring new wiring needs a licensed electrician in Ontario.
