How to Build a Deck Bench

To build a deck bench, you must have the right paraphernalia at hand. Once you have the utilities prepared, it will be easier to do the work.

Required Tools and Equipment

Saw (circular type preferred)
Hammer (regular size)
Wrenches or sockets
Screwdrivers (different sizes)
Stock (have some 2 x 4, 4 x 4 and 2 x 2)

Note: the size of the lumber will also depend on how big the bench is. Before you start set down in paper the measurements. This will aid in determining how much stock you’ll need. You can go to a hardware store and make inquiries about wood types.

Making the Base

Use the saw to cut four pieces of wood. To build a deck bench, set two of the pieces upright. Place the two other pieces in between them. Drill openings and use screws to hold the four pieces together. The number of bases you should make depends on the length of the bench. Ideally you should have one base per 3 to 4 ft of the seat’s length.

Making the Seat

You can use 2 x 4 or 2 x 2s. Set each one with half an inch of space. To connect the seat boards utilize screws. Before putting the other pieces in place, make sure all the pieces are of equal length. To build a deck bench correctly these need to be of similar length. If they are all proportional fasten them with screws or nails. The screw heads have to be about 1/8 inch deep.

Saw a couple of boards (1 x 4). Screw them onto the seats tightly. Use the sander to eliminate rough edges. Alternatively a router can be used instead. Either one will do nicely. Be sure to clear away any excess splinters or dirt off the seats.


It is possible to conceal the screws. After countersinking, cut a circular piece of wood and put them on top. Set them on the screw holes and glue. The ideal height is subject to personal preference. Most however, prefer 15 inches. Use a ruler to check the height of your favorite chair.

If you are going to apply paint after you build a deck bench, keep the following mind.

Never use any with lead. Some people also get dizzy when exposed to the smells of paint. If you are one of those, put on a mask. The strokes should be smooth and consistent. Too many layers will take too long to dry. The strokes need to be spread out evenly.

The workspace needs to be clear too. Nails and screws can get lost easily. To make things more manageable, have the tools side by side. Don’t mix the screwdrivers, nails and other tools. By segregating, you’ll have no problems finding the tools when you need to use them.

When you’re done, you can sit down and relax. As you’ll discover, the process of learning to build a deck bench is not that hard at all.
