IKEA kitchen installation guide for DIY cabinets, rails and worktops
What this IKEA kitchen installation guide covers
This IKEA kitchen installation guide is for homeowners who want to understand the order of work before choosing a DIY installation or booking a professional service. The basic sequence is straightforward: confirm every box and appliance, prepare a square and level room, mark the cabinet layout, mount the suspension rails, hang and align the cabinets, then finish with fillers, worktops, sink, appliances, doors, drawers and final adjustments.
The difficult parts are usually not the flat-pack cabinet boxes themselves. Problems more often come from measurement errors, uneven walls, incorrect rail fixing, utility connections, worktop cut-outs and rushed final checks. For more related project guidance, browse our installation guides.
IKEA’s U.S. kitchen installation guide dated March 2026 makes two important points at the start: use the guide together with the product assembly instructions, and only dismantle the old kitchen after checking that the new parts and appliances are present. It also says kitchen parts and countertops should be stored indoors at normal room temperature and humidity. (ikea.com)
Before delivery and demolition
Confirm the plan before the room is taken apart
An IKEA kitchen installation should begin with the documents, not with a drill. Print or save the IKEA planner drawings, product list, order list and freight list. Then compare the delivered cartons against those documents before demolition. A project can stop because of missing hinges, drawer slides, cover panels or fillers even when all the main cabinet boxes have arrived.
The most useful pre-installation check is to walk the room with the plan and mark what must be true for the design to work. Are the water, gas, electrical and ventilation points where the cabinets, sink, cooktop, dishwasher and hood need them? Are the corners close enough to square? Is the floor level enough for the cabinet run to align? IKEA’s installation guide tells installers to draw the new layout directly on the wall and verify that utility connections match the plan before fastening suspension rails. (ikea.com)
Do not treat utilities as a cabinet task
Cabinet assembly is a DIY-friendly job for many careful homeowners. Gas, water and electrical work are different. IKEA’s own guide says electricity, gas and water should be shut off before removing the old kitchen, and that qualified professionals should disconnect and connect gas, water and electricity. Later, at the worktop and appliance stage, the guide again says water, gas and electricity connections must be completed by qualified professionals according to valid local safety regulations. (ikea.com)
That distinction matters. A neat cabinet installation can still create inspection, warranty or safety problems if appliance connections are improvised. Before installation day, decide who is responsible for each trade or task: demolition, wall repair, floor leveling, plumbing, electrical, gas, ventilation, countertop templating or cutting, and backsplash work.
The installation sequence IKEA expects
Prepare the room and mark the cabinet positions
After the old kitchen is removed and the utilities are safely shut off, the room should be prepared for cabinets. This is the stage for wall repair, priming or painting areas that will be hard to reach later, addressing flooring transitions and checking whether walls can support the rail system. IKEA advises checking that walls and floors are even, identifying the highest point of the floor, checking corners with a try square and using a level on walls and floors. (ikea.com)
Marking the layout on the wall helps catch conflicts before cabinets are fixed. Draw the cabinet widths, appliance spaces, rail lines and tall cabinet positions. Mark studs or solid support locations. If the wall material is plaster, wood, masonry or another surface, the correct fastener will vary; IKEA notes that cabinet hardware is not supplied for every wall type and that appropriate hardware must be chosen for the wall. (ikea.com)
Mount the suspension rails accurately
The suspension rail is the backbone of a SEKTION-style IKEA kitchen. It allows cabinets to hang and adjust, but only if the rail is straight, level and securely fixed. IKEA’s guide gives specific reference heights: the base cabinet rail is shown at 32 1/16 in. to the bottom of the suspension rail, with 30 in. wall cabinets at 82 1/16 in. and 40 in. wall cabinets at 92 1/16 in. to the bottom of their rails. The same guide notes that wall cabinets need 1/2 in. clearance above the rail so they can be lifted into place, and the illustrated measurements provide 20 in. between the wall cabinet bottom and the counter when using a 1 1/2 in. thick countertop. (ikea.com)
These dimensions do not replace the specific instructions for the products in the order, but they show why guessing is risky. Start from the highest point of the floor, not from a low spot. Fasten the base rail first, check it with a level, and use suitable spacers where uneven walls would otherwise pull the rail out of line.
Hang cabinets before final tightening
In most layouts, IKEA recommends installing wall cabinets before base cabinets so the installer has more room to move. One stated exception is a single-line kitchen with a high cabinet at one end, where the high cabinet should be installed first. Base cabinets usually start from the corner; the following cabinets are then hung, connected and aligned before all screws are fully tightened. (ikea.com)
Do not rush the alignment stage. Check that each cabinet front plane is flush with the next one, that the legs are adjusted consistently, and that sink bases and appliance spaces line up with the plumbing and electrical plans. Cut openings for plumbing and utilities before putting a cabinet in place, and remember that opening locations can affect drawer placement.
Fit fillers for the room you actually have
Fillers are not just cosmetic strips. They help doors and drawers open properly near walls, appliances and corners. IKEA’s guide describes cutting filler pieces to match walls that are not perfectly straight and fastening support strips so the filler stays in place. It also recommends sealing around filler pieces with silicone for an airtight seal. (ikea.com)
This is where many DIY projects slow down. A room may look square until a long cabinet run exposes small deviations. Scribe fillers to the wall rather than forcing the cabinet run out of alignment.
Worktops, sinks, appliances and islands need extra caution
Once cabinet frames are fixed, the project shifts from modular assembly to cutting, sealing and trade coordination. IKEA’s guide says to check the worktop size before fitting and to use the specific assembly instructions for sink, cooktop, lighting and appliance installation. For pre-cut worktops, it describes cutting to length, marking the sink from the underside, drilling inside the corners before using a jigsaw, and applying polyurethane silicone across sawn edges to reduce moisture penetration. (ikea.com)
| Area | What to verify | Why it matters |
|---|---|---|
| Worktop length | Proof-measure before cutting | A short cut cannot be corrected with adjustment screws |
| Sink and cooktop openings | Use product templates and assembly instructions | Incorrect cut-outs can weaken the worktop or misalign fixtures |
| Sawn edges | Seal exposed edges where required | Moisture damage often starts at unprotected cut edges |
| Hood or fan | Follow the exact product measurements | Ventilation performance and safety depend on clearances and routing |
| Island cabinets | Use a proper floor anchoring method | Freestanding cabinets need secure resistance to movement |
Kitchen islands require separate planning because they cannot rely on a wall rail. IKEA’s guide states that an island must be secured to the floor by building an anchoring frame, and it warns installers to be aware of amenities such as floor heating or plumbing when fastening into the floor.

DIY installation vs IKEA installation service
The right choice depends less on confidence with flat-pack assembly and more on site conditions. A simple straight run in a square room with a laminate worktop may be manageable for a careful DIY installer. A larger room with tall cabinets, integrated panels, uneven floors, stone or specialist countertops, utility relocation, complex lighting and a visible island usually benefits from professional coordination.
IKEA’s U.S. installation service information says its kitchen installation service includes installation, fitting and securing of IKEA cabinets, rails, filler pieces, plinths, decoration strips and cornices. It also lists fitting IKEA laminate and butcher block or wood worktops, creating cut-outs for hobs and sinks, installing IKEA supplied appliances, sinks and taps, mounting plug-in cabinet lighting and sealing joints and cut-outs. However, the same page says electrical, plumbing and gas connections are not included with appliance installation, and lists trade services such as demolition, appliance hook-up, backsplash tiling, electrical, plumbing and painting as separate referral-partner items. (ikea.com)
IKEA’s installation service process also places responsibilities on the homeowner. Before installers arrive, the customer is expected to check delivered items for missing or damaged boxes and store flat-pack boxes and appliances in or near the installation room. During installation, the customer must provide clear access, adequate power, lighting and heating, and protect nearby belongings from dust or disruption. (ikea.com)
One detail is especially important if you are mixing DIY and paid installation. IKEA’s kitchen installation service page states that an average 10-cabinet kitchen installation takes between 2 and 3 days, but it also says a service provider cannot install cabinets that the customer has already assembled if the installation warranty is to apply. For IKEA Home Services to install the kitchen, it must complete the relevant parts from start to finish for the installation warranty. (ikea.com)
Quality checks before you finish
Before doors, drawers and shelves go in, inspect the cabinet frames as a system. Rails should be level, base cabinets should be aligned to one another, tall cabinets should be plumb, and appliance openings should match the actual appliance dimensions. After the countertop is secured, check that sink and cooktop cut-outs are sealed as required and that any exposed substrate is protected.
Doors and drawers are the final visual test. IKEA’s guide advises installing drawer slides, then drawers before doors and shelves, and finishing with knobs, handles and internal solutions. Outer and inner drawer slides fit in different rows of cabinet holes, so follow the assembly instructions for each product rather than relying on memory from another drawer type. (ikea.com)
If you used IKEA installation, do not sign off casually. IKEA’s installation service process says the customer should inspect completed work with the installer and note issues or concerns on the certificate of completion; issues not noted at that time may not be accepted later except for latent defects covered by product and service guarantees. (ikea.com)
Keep all assembly documents, instruction manuals, product lists, receipts and spare parts. IKEA’s warranty page lists a 25-year limited warranty for many SEKTION kitchen system parts, but it also says limited warranties do not apply to products that have been stored, assembled or installed incorrectly, used inappropriately, altered or cleaned with wrong methods.

Common mistakes to avoid
- Demolishing too early. Wait until all key parts and appliances are present, especially if the kitchen is your only cooking space.
- Starting rail heights from the wrong floor point. Measure from the highest point of the floor so the cabinet run can be leveled correctly.
- Using generic wall fasteners. Match the fastening method to studs, blocking, masonry or the actual wall structure.
- Fully tightening cabinets too soon. Leave final tightening until the run is aligned and appliance openings are verified.
- Ignoring fillers. Doors and drawers need clearance at walls, corners and appliance edges.
- Cutting the worktop before proof-measuring. Check the installed cabinet run, not just the drawing.
- DIYing utility connections. Use qualified professionals where gas, water, electrical and local safety rules apply.
Frequently asked questions
Can a homeowner install an IKEA kitchen without a contractor?
Yes. Many cabinet assembly and hanging tasks are designed to be DIY-accessible, but the project still requires accurate measuring, wall preparation, correct rail fastening and patient adjustment. Utility disconnection and connection should be handled by qualified professionals, and local permit or building requirements should be checked before work starts.
What is the most important measurement in an IKEA cabinet installation?
The suspension rail layout is one of the most important measurement stages because it controls cabinet height and alignment. IKEA’s guide gives rail height references, but the installed products, worktop thickness, floor level and room conditions must all be verified before drilling.
Should wall cabinets or base cabinets be installed first?
IKEA’s guide says wall cabinets are usually installed first because there is more room to move before base cabinets are in the way. A stated exception is a single-line kitchen with a high cabinet at one end, where the high cabinet should be installed first.
Does IKEA installation include plumbing and electrical connections?
IKEA’s U.S. service information says cabinet, worktop, sink, tap, appliance fitting and some finishing tasks may be included in the installation service, but electrical, plumbing and gas connections are not included with appliance installation. Those trade tasks may need separate professionals or referral-partner services.
How long does an IKEA kitchen installation take?
IKEA’s service page says an average 10-cabinet kitchen installation takes between 2 and 3 days. That figure is a service reference, not a promise for every home. DIY projects can take longer, especially when walls are uneven, parts are missing, worktops need cutting or utilities must be moved.
