This step by step diy article is about 2×4 bunk bed plans. I had many requests for designing a basic bunk bed that resembles with my very popular 2×4 bed frame. Therefore, in this article you can see my take on that. You only need 2x4s for the frame of the bunk bed, and a few 1x4s for the support slats. This project has been designed for a twin mattress so make sure you make adjustments, if you need other size.
Always aligned the components before locking them together with screws. In addition, we recommend you to pre-drill the lumber, otherwise the wood might easily split. Add glue to the joints, if you want to enhance their bond. Smooth the cut edges with fine grit sandpaper and remove the residues using a vacuum cleaner. Make sure you take a look over the related plans to get an idea about what you can build for your home.

Building a 2×4 bunk bed
First of all, you need to assemble the headboard. Therefore, start by assembling the frame from 2x4s. Drill pocket holes at both ends of the horizontal supports and insert 2 1/2″ screws to lock everything together tightly. Align the edges flush and make sure the corners are square.
Next, fit the 2×4 slats to the panel. Cut a wood block at 1 7/8″ and fit it between the slats to create even gaps. Drill pocket holes at both ends of the slats and insert 2 1/2″ screws to lock everything together tightly.
Next, join the headboards to the footboards by attaching the 2×4 side rails. Drill pocket holes at both ends of the rails and lock them into place with 2 1/2″ screws. Make sure the corners are square and leave no gaps between the components. Use a spirit level to check if the rails are horizontal.
Fit 1×2 cleats to the interior faces of the side rails. Align the cleats with attention, drill pilot holes and insert 1 5/8″ screws to lock them into place tightly. Add glue to the joints and align them flush with the bottom edge.
Fit the 1×4 slats to the cleats, every 2 1/2″, as shown in the diagram. Place a scrap piece of 1×3 lumber between the slats to create even gaps. Drill pilot holes through the slats and insert 1 5/8″ screws to lock them into place tightly. Cut the slats at 39″ long.
Fit the 2×4 ladder support to the front of the bunk bed. Plumb the support, drill pilot holes and insert 2 1/2″ screws to lock them into place tightly.
Fit the steps to the interior of the bunk bed and lock them into place with screws.
Next, attach the 2×4 rails to the bunk bed. Place a scrap piece of 2×4 lumber between the rails to create even gaps. Drill pilot holes and insert 2 1/2″ screws to lock the rails into place tightly.
Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint to enhance the look of the wood. Take a look over my 2×4 queen size bed plans and over my 2×4 loft bed plans.
