This step by step diy woodworking project is about triple bunk bed frame plans. If you want to build a three bunk bed, you should check my step by step instructions. I have designed this bunk bed so you can save time and use just common materials and tools. Make sure you take a look over the rest of plans to see alternatives and more projects for your garden.
Work with attention and don’t forget that a good planning will save you from many issues and it will keep the costs withing the total budget. Invest in high quality materials, such as pine, redwood or cedar. Drill pocket holes before inserting the galvanized screws, to prevent the wood from splitting. Add waterproof glue to the joints, in order to enhance the rigidity of the structure. See all my Premium Plans HERE.

Building a triple bunk bed
The first step of the project is to build the bed frame for the triple bunk bed. Cut the components from 2×6 lumber. Align the edges flush, making sure the corners are square. Drill pilot pocket holes at both ends of the 76″ long components and insert 2 1/2″ screws to lock them together tightly. Add waterproof glue to the joints.
Next, attach the 2×4 cleats to the bed frames. Drill pilot holes through the cleats and insert 2 1/2″ screws to lock them into place. Add glue to the joints and make sure the corners are square.
Attach the 1×4 support slats to the cleats. Cut a 1 1/4″ wide block of wood and fit it between the slats so you create even gaps between the components. Drill pilot holes and insert 1 1/4″ screws to secure them into place tightly.
Attach 2×2 lumber to the two bed frames. Use a spirit level to make sure the legs are plumb and to check if the frames are horizontal. Drill pilot holes and insert 2 1/2″ screws.
The next step of the project is to attach the third bed frame to the bunk bed. Attach the 2×2 legs to the end of the bed frame. In addition, attach the 1×4 supports so you can secure the third bed frame to the top bed frame.
Attach 1×4 rails to the third bed frame. Drill pocket holes at both ends of the slats and secure them to the legs with 1 1/4″ screws. Add glue to the joints for a neat result.
Attach 1×4 slats as rails to the top bed frame. Drill pocket holes at both ends of the slats and secure them to the legs with 1 1/4″ screws. Leave no gaps between the components.
Attach the 2×2 steps to the ladders. Drill pocket holes at both ends of the steps and secure them to the ladder supports with 2 1/2″ screws. Make sure the corners are square and add waterproof glue to the joints.
Attach 1×2 trims to the top of the rails. Cut the ends at 45 degrees for the joints. Align the edges flush and use 1 1/2″ brad nails to secure them into place tightly.
Fit the mattresses to the bed frames. I have designed this triple bunk bed so you can fit single mattresses.
Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-200 grit sandpaper and remove the residues with a damp cloth.
Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Don’t forget to LIKE, SHARE and Pin this project, if you’ve enjoyed it.
