Kitchen Design Tips from Actual Installers
We have installed thousands of kitchens. Here are the things we have learned that most design guides do not tell you.
Layout
The work triangle still matters
Sink, range, refrigerator. These three points define how you move through a kitchen. When they are positioned well, cooking is efficient and comfortable. When they are not, you feel it every single time you use the kitchen. Before you finalize your layout, trace the path between these three points. If any leg of the triangle is longer than about 9 feet, you will spend a lot of time walking. If the legs overlap — if traffic cuts through the triangle — the kitchen will feel frustrating to work in.
The dishwasher should not be too far from the sink
This sounds obvious but it gets overlooked when people are focused on storage and cabinet counts. The dishwasher needs a water supply and drain connection that ties into the sink plumbing. Putting it on the other side of the kitchen means running new supply lines through cabinets, walls, or floors. Standard practice is to position the dishwasher immediately to the left or right of the sink. Moving it more than a few feet becomes a plumbing project.
Corner cabinets need planning
Blind corner base cabinets require filler strips so the adjacent door or drawer can open without hitting the cabinet next to it. If you order a blind corner without accounting for the filler, you either cannot open the drawer beside it or you end up with a gap. Plan the filler before you finalize your cabinet list — a typical blind base needs a 3- to 6-inch filler on the open side, depending on the door and drawer configuration next to it.
Islands need at least 36 inches clearance on all sides (42 is better)
Code in most areas requires 36 inches of clearance between an island and the surrounding cabinets or appliances. That is the absolute minimum — you will feel cramped, especially if two people are cooking. If your kitchen allows it, aim for 42 to 48 inches. You will use that space every day. Also remember that an island with seating needs enough overhang on the seating side — 12 inches for bar stools, 15 inches if you want people to sit comfortably.
Cabinet Selection
Measure twice. Then measure again.
We put this in the measuring guide and we are putting it here too, because the cost of getting it wrong is high. Cabinet orders are not returnable once cut. An inch off on a wall measurement can mean a cabinet that does not fit. An inch off on an appliance opening means an appliance that does not fit. Measure the room, measure again a few days later, and have someone else check your numbers before you order.
Order sample doors before committing to a style
Colors look different in photos than they do on your wall. A white that looks warm and creamy on a screen can look stark and blue in your kitchen's lighting. A gray that looks sophisticated in a showroom can look cold in a north-facing kitchen. Order sample doors, hold them up in your actual space at different times of day, and live with them for a few days before you commit. Sample doors cost a few dollars. Changing your mind after 50 cabinets are on the truck costs a lot more.
Upper cabinets: 30-inch or 36-inch tall depends on ceiling height
With a standard 8-foot ceiling, 30-inch uppers leave about 18 inches above the cabinet to the ceiling. You can fill that with crown molding and a small filler, or leave it open. 36-inch uppers give you more storage and a more substantial look — they reach closer to the ceiling and feel more built-in. With a 9-foot ceiling, 36-inch uppers are the better choice. With a 10-foot ceiling, you can stack cabinets or go to a tall pantry. Do not just pick a size because it is "standard" — pick based on what your ceiling height actually allows.
Do not forget toe kicks, fillers, end panels, and crown molding
These finishing pieces are what separate a cabinet installation from a built-in kitchen. Toe kicks cover the base gap and shims. Fillers close the space between the last cabinet and the wall. End panels cover the exposed sides of cabinets at the end of runs or next to appliances. Crown molding ties the upper cabinets to the ceiling. None of these are optional if you want the kitchen to look finished. Price them into your order from the beginning — they add up, and people routinely forget them.
Common Mistakes
Ordering without accounting for appliance dimensions
Appliances have standard sizes but they are not universal. A refrigerator that is listed as 36 inches wide may have handles that add another 2 inches of depth. A range may require a specific clearance on each side per code. A microwave above the range has minimum clearance requirements from the cooktop surface. Read the specs for every appliance you plan to use. Do not assume standard sizes will work without checking.
Forgetting that plumbing and electrical may need to move
If you are changing the layout — moving the sink, relocating the range, adding an island — the plumbing and electrical have to follow. This is a significant cost that many people do not budget for. Even staying in the same footprint, you may discover that an outlet is exactly where a cabinet needs to go, or a supply line runs through the space where a cabinet would sit. Walk through the layout with a plumber and electrician before you finalize anything significant.
Not planning for corner situations
Corners in kitchen layouts require specific cabinet types — blind base cabinets, lazy Susan corners, diagonal corner cabinets, or pie-cut doors. Each option has different space requirements and different filler needs. Many people lay out a kitchen ignoring the corners and then realize at the end that nothing fits the way they planned. Start your layout from the corners and work outward.
Assuming walls are straight and floors are level
They are almost never perfectly straight or level, especially in older homes. Layouts planned on paper assuming perfect right-angle corners hit walls that are actually 89 degrees or 91 degrees. Cabinet runs that look flush in the design end up needing shims and scribing in real life. Measure the actual angles and check for plumb before you commit to a layout. See the measuring guide for how to do this.
Not ordering enough
Better to have an extra filler strip and a spare cabinet on hand than to wait three weeks for a second shipment while your kitchen sits half-finished. If you are between two sizes on a filler, order the larger one — you can always cut it down. If a run works with either a 9-inch or a 12-inch cabinet in a particular spot, order both and return the one you do not use. The inconvenience of returning something you did not need is far less than the inconvenience of waiting for something you do.
