Free Frameless European style base cabinet plans that you can build for your kitchen, bathroom, office, home theater or other renovations. This is more than just how to build a base cabinet. It's practically everything you need to know about building frameless base cabinets before you begin.
When I first tried to learn how to build cabinets I had a hard time finding all the information I needed. There was a little bit here, a little bit there, but nowhere did I find all the information all in one place. I did my best to combine most of what you need to know in one place to make things easier for you. It's a bit of a long read but if you're serious about building your own cabinets it to save money it's well worth the time. One book I commonly saw mentioned was
Build Your Own Kitchen Cabinets (Popular Woodworking) by Danny Proulx
which might be worth considering. I haven't read it myself.
Frameless cabinets are easy and affordable to build. They also provide more usable storage space over face frame cabinets. Over the years I've looked into different construction techniques for frameless cabinets and have put all that information together to help you build your own frameless base cabinets. To build matching wall cabinets see my post on
How To Build Frameless Wall Cabinets. Construction of the base cabinet is relatively straight forward. The most difficult aspect is planning and sizing which will make up a good bit of this post.
Frameless cabinets have a more contemporary look but can be dressed up with trim and more elaborate doors to have a more traditional look.
In this article we're going to focus on how to build a frameless base cabinet carcass. The cabinet carcass is the main box of the cabinet which does not include doors, drawer fronts or
drawer boxes. The cabinet carcass can be configured in a number of different ways to allow doors, drawers, open shelving or any combination which suits your needs.
The frameless cabinet design I find easiest to build, install and provides exceptional strength is the one pictured right. It is made of 3/4" plywood throughout, including a full back. The top consists of 2 4" stretchers. Up to a 30" wide standard base cabinet carcass can be constructed out of a single sheet of 4' x 8' plywood.
This is the design we'll focus on but I'll address some other options and aspects.
Cabinet Base Options
There are 4 different ways you can configure the base of your lower frameless cabinet. Each one has it's pros and cons.
Standard Base
The standard base has the sides and back of the cabinet extend all the way down to the floor and is notched in the front to provide a toe kick. The notch is 3" deep and 4-1/2" tall. There is a "sub toe kick" that provides additional support for the bottom and makes it easy to apply your finished toe kick cover (such as a decorative baseboard) over a continual stretch of cabinets for a seamless look.
This type of base is marginally more difficult to build and uses a little more plywood but you get a single cabinet unit which has advantages. Each cabinet needs to be shimmed individually to make it level. This is what most semi-custom cabinets you buy look like.
Standard Base No Toe Kick
Sometimes you won't need a toe kick at all such as when you're building a built-in desk or library. This base has the same pros and cons as the standard base except it has no toe kick. Instead a decorative board, the same thickness of the doors, is applied over the base of all cabinets after installation for a seamless look.
Adjustable Cabinet Legs
Adjustable cabinet legs (such as these
Platte River Cabinet Leveling Legs
or better
Blum Leg Levelers
and
Blum Kick Plate Clips
) make installation of cabinets very easy on uneven floors and let's face it, most floors have some degree of unevenness to them.
What's more, it's easy to make changes to the cabinet height during installation (and with a little more work after installation) if the need arises.
The toe kick board gets screwed onto a plate that clips onto the legs after all cabinets have been installed and leveled. Unlike the standard base, it's easy to add a toe kick on the side of a cabinet such as the exposed end of a cabinet run. It also makes it easier to change the toe kick board to change the look of your kitchen at a later date.
Since the wood cabinet is kept off the floor these are good for spaces where dampness is an issue such as in basements, garages or other areas where cabinets are installed on a concrete slab floor.
The downside is it will add a little bit extra to the cost of each cabinet but not much and the benefts will usually outweigh the cost.
Separate Base Platform
Finally you can create a separate base platform that consists of a frame made up of 2x4's with a plywood top giving you a total toe kick height of 4-1/4" (3-1/2" 2x4 + 3/4" plywood). What's nice about this arrangement is you level the platform before installing the cabinets. Then you just need to place your cabinets on the platform without having to do much if any additional leveling. The base is also sturdier than a base that is part of or attached to your cabinets.
You can even create toe kicks on the sides of cabinets where necessary such as the end of a cabinet run or a kitchen island.
Cabinet Back Options
You also have a few options on how you construct the back of the cabinet.
Full Back
You can choose to use a full back that is the same 3/4" plywood used for the rest of your cabinet. (Some people choose to use 1/2" but I find it's easier to just use one thickness throughout.) This configuration will give you an enclosed cabinet with exceptional strength which is important when installing heavy stone countertops and supporting heavy countertop appliances. It can be a little more money but not much if you plan your cuts out well. We'll be using the Full Back in the example in this article.
Nailer Back
Sometimes you don't care if a cabinet has a back or not, such as in garage storage cabinets. This option can save on material. Instead of having a full back you create 2 nailing strips out of 3/4" plywood for the top and bottom of the back so you have something to affix the cabinet to the wall with and to provide rigidity and strength to the cabinet.
1/4" Back With Nailers
In some cases you'll want to have an enclosed back but you want to save some money. You can use nailers as in the previous option but also staple a 1/4" plywood back over the nailers to provide a finished look. This is cheaper than using a full back and provides a lighter cabinet. Many semi-custom cabinet manufacturers use this technique. It doesn't add as much strength as a full back but it does give you the look and feel of one. The 1/4" plywood is more prone to warping than the 3/4" plywood and may bow out over time.
What You'll Need
Tools
Materials
3/4" hardwood veneered plywood is the best option for building your cabinets. If you're taking the time to build your own cabinets might as well make them the best you can. You're still going to save money over most semi-custom cabinets that are usually made out of 5/8" particle board and wind up with a better quality cabinet.
Plywood comes in different apperance grades. A1 being the best. If you plan on painting your cabinets or don't care about the apperance (garage cabinets) you can use a lower appearance grade cabinet. If you must use MDF to save money make sure you glue your joints in addition to using the appropriate pocket screws .
Step 1: Calculate Cabinet and Component Dimensions
Chances are you will want to build a different sized cabinet than what I'm going to show in this example. In most cases you'll want to build multiple cabinets of different sizes so let's go over how to calculate the dimensions of the different components that make up the carcass.
Cabinet Height
The height of the cabinet will be determined by the application. For example the standard height for the top of a kitchen work surface is 36". If our countertop thickness will be 1-1/2" that means our cabinet needs to be 36" - 1-1/2" or 34-1/2" tall.
Cabinet Height = Desired Top Height - Top Thickness
Some common work type heights are:
- Kitchen 36"
- Bathroom Vanity 33" to 36"
- Desk 30"
Cabinet Depth
The standard depth for kitchen cabinets is 24" which includes the door. This should work for most situations but you may want to check the specifications of your appliances (slide in range, dishwasher, etc) to see if they require a different size.
For bathroom vanity cabinets the standard depth is 21". For desks and other custom cabinets you can choose whatever depth works best for you though most are 20-30" deep.
Cabinet Width
This one is easy. The cabinet width is determined by your design and your preferences.
Cabinet Component Dimensions
In our example we're going to be constructing a 30" W x 34-1/2" H x 24" D cabinet using 3/4" plywood. We'll be making it with a standard base and a full back. In all the dimensions below the direction of the grain will follow the height.
*Note: if you're using thick edgebanding you'll need to factor that in where appropriate. Most edgebanding is less than 1/32" thick which is pretty insignificant so I don't factor it in most of the time. As long as it's used consistently and applied before assembly I consider it an acceptable margin of error. Wood expands and contracts. Not all human cuts are very accurate. Consistency is more important over precision and it makes calculating sizes and cutting components much easier.
Cabinet Side Dimensions
We will need two sides for the cabinet. The height of the side is simply the height of our cabinet minus an external base if using one. The width is the depth of the cabinet minus the thickness of the door.
Cabinet Side Height = Height of Cabinet - External Base (34-1/2" - 0 = 34-1/2")
Cabinet Side Width = Depth of Cabinet - Door Thickness (24" - 3/4" = 23-1/4")
We'll need 2 34-1/2" x 23-1/4" sides for our cabinet.
Cabinet Bottom Dimensions
The height for the bottom of our cabinet will need to be the width of our cabinet minus twice the thickness of the sides. The width will be the depth of the cabinet mins the back depth minus the door thickness. (Be careful sometimes advertised size isn't true size. A
digital caliper
can help you get an accurate thickness measurement. Your 3/4" plywood may sometimes be 23/32" or something else entirely.)
Cabinet Bottom Height = Cabinet Width - 2 x Side Thickness (30" - 2 x 3/4" = 28-1/2")
Cabinet Bottom Width = Cabinet Depth - Back Thickness - Door Thickness (24" - 3/4" - 3/4" = 22-1/2")
We'll need one back that is 28-1/2" x 22-1/2".
Cabinet Shelf Dimensions
If you're installing a shelf in your cabinet (as our example does) you want to size it appropriately. It's basically the same dimensions as the Bottom minus a little depth (1/2") so that it stays clear of the doors even if there is some expansion.
Cabinet Shelf Height = Cabinet Bottom Height (28-1/2")
Cabinet Shelf Width = Cabinet Bottom Width - 1/2" (22-1/2" - 1/2" = 22")
Cabinet Back Dimensions
We can use some of the previous dimensions we calculated to determine the dimensions of the back of the cabinet. The back of the cabinet will rarely be seen and even when it is it won't be lit very well. While it's nice to have a consistent grain direction for the backs you might be able to save a sheet of plywood by mixing the grain direction up for the backs if you don't mind a little inconsistency in an inconspicuous location.
Cabinet Back Height = Cabinet Bottom Height (28-1/2")
Cabinet Back Width = Cabinet Side Height - Stretcher Thickness (34-1/2" - 3/4" = 33-3/4")
Our cabinet needs one back measuring 28-1/2" x 33-3/4".
Stretcher and Sub Toe Kick Dimensions
Grain direction should be along the long side but in most cases these components will hardly be seen so feel free to change the orientation if it helps you maximize the usage on your cut plan.
Stretchers should be 3-4" wide, the sub toe kick should match the height of the notch cut into the base (4-1/2" in our example). The height of both should be the same as the Cabinet Back Height (28-1/2").
We'll need 3 stretchers (4" x 28-1/2") and one sub toe kick (4-1/2" x 28-1/2")
Step 2: Attach Side To Back
Wow! You've read all this way and we're just starting to put the cabinet together! Careful planning makes the rest of the process easy.
Start by applying edgebanding to the front of both cabinet sides.
Drill pocket holes around the top and sides of the Cabinet Back and attach it to one of the sides as shown.
Notice that the bottom of the back is flush with the bottom of the side. There is a 3/4" space on the top of the back for the stretcher that will eventually be installed.
Step 3: Attach Bottom
Apply edgebanding to the front of the bottom, drill pocket screw holes as shown and attach the Bottom to the Side and Back previously assembled. Notice that the bottom of the Bottom is flush with the notch for the Toe Kick. Use your square to make sure everything is aligned properly.
Step 4: Attach Other Side
Attach the other side to the cabinet assembly using the previously drilled pocket holes in the Back and Bottom pieces.
Step 5: Attach Stretchers
Apply edgebanding to the front of the 2 stretchers that will be attached to the front. Drill pocket holes and attach to the cabinet making sure everything is square. The bottom stretcher on the front is for the first drawer. To minimize visibility of the pocket holes install them with the pocket holes facing up. (The drawer will hide the second front stretcher holes.)
In this example we're assuming the cabinet will have a single full width drawer and 2 lower doors. The spacing for this bottom section will be determined by the desired drawer height. The standard top drawer height is 6". We're planning for overlay drawers and doors. A 1/4" gap should be on the top to avoid any binding against the counter top. That means the second front stretcher should be 6-1/4" down from the top of the cabinet.
Step 6: Install Sub Toe Kick
The Sub Toe Kick helps support the cabinet and add rigidity. It also makes it easy to nail in the finished kick board after installation. Drill pocket screw holes and attach it between the cabinet sides as shown.
Step 7: Drill Shelf Pin Holes
Using the
Kreg Shelf Pin Jig make holes in the back and front of each side of the cabinet for shelf pins. Leave at least 3-4" on the top and bottom for room to install your door hinges depending on where you drill the bores for your hinge cups on the door.
Use the short side of the jig without the fence to get the holes 37mm from the front edge of the jig. When doing the back, flip the jig around.
When you're done, apply edgebanding to the front of the shelf, insert shelf pins in the appropriate locations and install your shelf.
pictured right) need a 1/2" clearance on each side of the drawer box. The clearance requirements should be available through the slide manufacturer.
you'll want to make your drawer boxes 22" to get full advantage of the full extension feature. Figuring out what size drawer slides to buy will be determined by your cabinets construction and size.
. Standard tape measures don't have markings down to 1/32" but if you don't have calipers you can stack 2 side pieces on top of each other and measure their combined thickness.
. Using it along with this 
makes it easy to make consistent daos in the drawer. The bits dull fairly quickly so you might want to pick up a spare and remember to feed the drawer side slowly and make 2 or 3 shallow passes instead of trying to cut the full depth of the dado all at once.
