How to Build a Cabinet for a Farmhouse Sink?

Some of you out there are trying to redesign different parts of your house on your own so that you can liven the space up a bit. But doing DIY projects at home is not always the easiest, especially if you don’t already have some type of experience with it.

DIY cabinet for a farmhouse style sink might be the next thing on your to-do list. But making the cabinet all by yourself is not going to be the easiest task in the house.

So, to make your life a little bit easier, we are going to give you a little tutorial on how to build a cabinet for a farmhouse sink?


The first thing we need to tackle before you get to the task in hand is to figure out all the items we will be needing when we make the cabinet.

Make sure you have all these on hand and don’t have to stop midway to make a run for the hardware store because you forgot to get something. This will delay the timeline.

Also, these measurements might not be the same for everyone, some might have a bigger sink and area so you would need a bigger cabinet, while some might have something smaller. So, we decided to go with the average sink and area size. You may adjust to your needs.

  • 3/4” plywood, this is needed for the bottom and the sides of the cabinet
  • 3/4” 1×4 pre-primed finger joint board, this will go towards the front
  • 3/4” 1×2 pre-primed finger joint board, this too would be needed for the front for design on the door
  • 3/4” 1×3 pre-primed finger joint board
  • 1/2” plywood panel for the back
  • 2×4 boards for base and support
  • A farmhouse-style sink
  • A faucet to go with it


You will need to be a little patient as the task in hand is going to require a bit of time and precision, and when done correctly, you will see the great result in how the sink and the cabinet look at the end of it all.

Step 1: Build the Base

The very first thing you are going to have to do for the cabinet is to build the base. It is important you do this step before anything else as all the other pieces are going to go on top of it, so the base is required.

You have to take the 2×4 pieces of wood and then trim them to your need. Then you have to measure how high up you want the cabinet to be from the floor and the diameters of the area you will be building it.

Once you have everything measured and cut to proportion, you can form the box-like structure. You will need to screw them together, so they stay intact.

Once you place it inside, you also need to screw it to the sides as you don’t want there to be any movements once you build the cabinet.

Step 2: Place the Bottom and Side Plywoods

Once the base is done, you will need to cut the 3/4” piece of plywood for the bottom part of the cabinet. The measurements need to be done based on the area it has to be fit into.

When you have measured and cut everything properly, you must place the plywood on top of the base and screw it into place.

After the bottom has been done, you are going to repeat the step for the sides as well. You must measure the far up the sink is going to be placed as well as how deep the cabinet is going to be. Only then you’ll have the correct measurements for the sides.

Step 3: Build Base Support for Sink

When you have the bottom, and the sides are done, you have to build support for the sink. You need this to be sturdy as the sink is going to sit on it, and a weak base might end up in a disaster for you.

Again you have to take the 2×4 pieces of board and cut them the needed size. You need four pieces of this. Two of them need to be screwed vertically on the ends of the right panel, and the other two need to go on the opposite end.

You should test out if the length is right for the sink before you complete building the whole cabinet, you would have to tear everything down and rebuild it if things are not done right.

Step 4: Make a Frame for the Front

Now that you have completed everything on the inside, you need to make the front part of the cabinet. This is where you will be needing all the pre-primed finger joint boards.

The 1×3 piece is going to go right infant of the area where the sink rests on the support. And the 1×2 pieces will go on the two sides of the cabinet, and lastly, the 1×4 is going to go at the bottom.

Just make sure you measure them correctly, you will be able to trim it if it is longer than needed, but cutting it too short would mean you need to use another piece.

Step 5: Build the Door

Once the frame is done, now you must make a door that would complete the cabinet.

You will need 5 pieces of wood for this job. One is going to be a 1/2” hardwood plywood, which will go as the center panel. Two of the 1×3 board will be for the sides and then the other two for the top and bottom.

The centerpiece needs to smaller in both length and width than what is actually needed for the door.

This is because the boards on the sides and the top and bottom will make up for the measurement there. You also need to make two holes on all four sides of the wood.

Now you must attach the top and bottom pieces to the centerpiece. Make sure the edges mesh well together. You also need to make a hole on each end of the boards.

And finally, you have to attach the side pieces. You have to make sure it all forms a rectangle, and no side is longer than the other.

And with that, you are done making the door.

Step 6: Paint the Front

The next thing on your to-do list would be to paint the front of the cabinet. You can choose whichever color you like.

Just make sure the paint you pick out is right for wooden surfaces. You don’t want it to start chipping after some time.

Step 7: Install the Sink and Faucet

By now, you are done making the cabinet, but your job will not be complete if you do not install the sink and faucet as well.

Installing the sink should not be very difficult, but you have to follow the instructions provided by the manufacturer to do it perfectly.

As for the faucet, this, too, can be done on your own. But if you are a little confused, you can always take some help from the internet.

You might have to make a few holes in the bottom and back of the cabinet for the pipes to be able to go through properly.

And with that, we are done installing our farmhouse style sink cabinet!

Final Words

I know this seems like a lengthy process, but once you are done making the cabinet on your own, you will be very pleased with the outcome, and might even want to take on more projects.
