In most kitchens, the finished floor goes down before the base cabinets, so the cabinets sit on top of the flooring. The main exception is a floating floor such as click-lock luxury vinyl plank (LVP), laminate or some engineered wood. Those floors must stay free to expand and contract, so cabinets and islands are usually installed first and the floating floor is run up to a riser or filler at the cabinet base. Always confirm the sequence against the specific flooring manufacturer’s installation instructions and warranty.
The order you choose affects appliance fit, toe-kick detailing, how much flooring material you buy, and how hard the next renovation will be. Working through the floor type first makes the rest of the decision much simpler.
The Short Answer, by Floor Type
Fixed floors are attached to the subfloor, either glued, nailed or set in mortar. For these, the usual sequence is floor first, then cabinets. Floating floors rest on the subfloor without fasteners and move with changes in temperature and humidity, so the sequence changes. A floating floor should not be pinned under the weight of cabinets and counters, which is why cabinets typically go in first with a riser or filler bringing the cabinet base up to the finished floor height.
The table below summarizes the typical sequence. It is a starting point, not a substitute for the product’s installation instructions.
| Floor type | How it attaches | Typical sequence | What to watch |
|---|---|---|---|
| Ceramic or porcelain tile | Mortar and grout over backer board or membrane | Floor first, then cabinets | Added height at appliance openings; subfloor flatness before tile |
| Glue-down or nail-down hardwood | Adhesive or fasteners to subfloor | Floor first, then cabinets | Moisture and movement of the wood; acclimation before install |
| Floating LVP or laminate | Click-lock joints, no fasteners | Cabinets first with a riser, floor run to the cabinet face | Expansion gap at every fixed object; manufacturer limits on loads |
| Floating engineered wood | Click-lock or similar | Cabinets first with a riser, unless the manufacturer says otherwise | Same movement and gap requirements as other floating floors |
Why Floor-First Is the Usual Default
A finished floor gives the cabinet installer a consistent plane to work from, and it means the floor runs under the cabinets rather than stopping at the toe kick. That continuous surface matters most when the kitchen is renovated again: if the cabinets sit on the subfloor, replacing the floor later usually means working around the cabinet footprint or removing cabinets.
Floor-first is also about leveling. Cabinets need a flat base, and a finished floor that has already been checked for flatness gives you one less variable during cabinet installation. If you install cabinets first, you are effectively locking them to the height and flatness of the raw subfloor, and any correction has to happen before the cabinets go down.
Fixed Floors: Tile, Glue-Down and Nail-Down Wood
Fixed floors are mechanically attached to the subfloor, and glue-down and nail-down installations often need little or no perimeter gap because the flooring cannot slide as a sheet. That is why tile, glue-down hardwood and nail-down hardwood can usually carry cabinets directly.
Ceramic and Porcelain Tile
Tile is rigid and heavy, and it performs best when the substrate is flat and stable. Before tile goes down, check the substrate against the tile manufacturer’s flatness tolerance: ANSI A108.02 requires tiled floors to have no variations exceeding 1/4 inch in 10 feet from the required plane, with no variation greater than 1/16 inch in 1 foot. Some installations call for a tighter 1/8 inch in 10 feet, and because wood and concrete substrates can change over time, substrate flatness should be evaluated just before tile installation.
Because tile adds height, account for that rise when you size appliance openings. A decoupling membrane or cement backer board is a common part of the assembly; follow the membrane manufacturer’s installation instructions for the specific product.
Glue-Down and Nail-Down Hardwood
Glue-down and nail-down installations behave differently from floating floors, and many need little or no perimeter gap because the flooring is mechanically fixed. Once installed, they can generally sit under cabinets, subject to the flooring manufacturer’s guidance on moisture and acclimation.
Floating Floors: LVP, Laminate and Floating Engineered Wood
Floating floors are not attached to the subfloor and expand and contract with temperature and humidity, so the gap around the perimeter absorbs that movement before the planks push against something immovable. An expansion gap is the intentional space left between a floating floor edge and fixed objects such as walls, cabinets, pipes, door casings and fireplace hearths.
That movement is why cabinets and islands generally should not sit on a floating floor. One secondary article quotes National Flooring Products as advising never to install cabinetry, islands or other permanent fixtures on a floated floor. Manufacturer instructions and warranty terms override general sequencing advice, so check the specific product’s documentation before you commit.
The Riser or Filler Method
The standard workaround is a riser, sometimes called a filler or cleat, installed in the cabinet footprint at the thickness of the finished floor. The cabinets sit on the riser at the same height they would if the floor ran underneath, and the floating floor runs up to the cabinet face and stops there. The riser keeps the floating floor free to move while the cabinets stay level with the rest of the kitchen.
Expansion Gap Dimensions
Typical perimeter gaps are about 1/4 to 1/2 inch for click-lock LVP and laminate, 5/16 to 1/2 inch for floating engineered hardwood, and 3/8 to 3/4 inch for solid hardwood, and the manufacturer’s specification overrides these general rules. Longer continuous runs require wider gaps and may need transition strips to break the floor into independent floating sections; if the longest dimension exceeds about 30 feet, plan a T-molding or transition strip.
Subfloor Flatness Before Cabinets or Flooring
Flatness is not the same as level: a floor can slope and still be flat enough, while waves and humps are the problem. Floating click-lock LVP is a mechanical system, and even small deviations in subfloor flatness can affect how the joints perform over time, producing gapping, peaking, broken locking edges and noise.
Most LVP manufacturers specify flatness of about 3/16 inch over 10 feet and 1/8 inch over 6 feet, with some rigid-core systems requiring 1/8 inch over 10 feet. Most flooring manufacturers publish a subfloor flatness tolerance of 3/16 inch over 10 feet, which ASTM F-710 codifies for resilient flooring. These values vary by product, so confirm the tolerance for your specific floor before leveling or installing.
Appliance and Countertop Height Checks
Floor thickness changes the height of every opening that is measured from the finished floor. A standard built-in dishwasher is typically 24 inches wide, about 34 to 36 inches high and around 24 inches deep, and fits standard base cabinet openings. Most dishwasher rough openings are 24 inches wide, 34 to 36 inches high and 24 inches deep, and most dishwashers have adjustable feet for adding height.
Measure dishwasher height from the floor to the lowest point of the countertop, so added flooring thickness reduces the available opening. Published manufacturer installation sheets should govern the final fit, especially where the counter, toe-kick or adjacent cabinets create tighter conditions than the raw opening suggests.
Ranges have the same exposure: the cooktop should finish level with the surrounding counter, and the appliance manual states the required opening and any height adjustment. Check that manual before the cabinets are set, because the fix is much cheaper at the planning stage than after the counter is installed.
Toe Kicks and Expansion Gaps
The toe kick is where the two sequencing methods look different in the finished kitchen. With floor-first installation, the flooring runs under the cabinet and disappears at the toe kick. With cabinets-first and a riser, the flooring stops at the cabinet face and the toe kick covers the transition.
The caulking rule follows the floor type, not the room. On a fixed floor, a bead of sealant at the toe kick is a reasonable way to keep mop water and small spills out of the joint. On a floating floor, do not caulk or otherwise pin the floor edge against the toe kick, because the floor needs to move and a rigid bead defeats the expansion gap. Use a trim piece or base shoe that allows movement instead.
When Cabinets-First Makes Sense
Cabinets-first is legitimate in more cases than the simple rule suggests. Floating floors are the clearest example, and the riser method lets you keep a continuous floor look without pinning the planks. The second common reason is material cost: if you are using an expensive floor, limiting it to the visible area rather than running it under the cabinets reduces the square footage you buy.
A third case is a floor that will be installed later in the project, or a slab or stone floor where the cabinet base needs to be set independently. In each case, confirm the manufacturer’s guidance for the specific floor and appliance before relying on the sequence.
Common Planning Mistakes to Avoid
- Sizing the dishwasher opening without the floor. The opening is measured from the finished floor, so added thickness reduces clearance.
- Caulking a floating floor at the toe kick. The edge needs to stay free to move.
- Skipping the flatness check. Even small deviations can affect click-lock joints over time.
- Assuming cabinets can sit on any floating floor. The restriction comes from manufacturer guidance, so read the product documentation before deciding.
- Choosing the sequence before the floor. Floor type, not habit, should drive the decision.
Decision Rule by Floor Type and Budget
Start with the floor. If it is fixed (tile, glue-down or nail-down wood), install the floor first and set the cabinets on top, after confirming flatness and appliance opening heights. If it is floating (click-lock LVP, laminate, some engineered wood), install the cabinets first on a riser at the finished floor height, run the floor to the cabinet face, and leave the expansion gap free at every fixed object.
Use the budget trade-off to refine the choice, not to override the floor manufacturer’s requirements. Whatever you decide, check the flooring manufacturer’s installation instructions, the appliance manuals and the subfloor flatness tolerances before installation begins. The National Kitchen & Bath Association publishes planning guidelines that cover clearance and equipment location recommendations, which are a useful cross-check for the overall layout.
