Hi it’s Amy from Hertoolbelt, back with another build plan.  Cassity’s outdoor coffee table on her deck has made a few appearances on Remodelaholic like here and here, and I love it.

By popular request, I’ve put together a woodworking plan inspired by this piece (no longer available in stores) so you can build your own DIY outdoor coffee table.

Square Outdoor Coffee Table With Wood X Base, Remodelaholic
Of course, this square coffee table could be right at home in your living room, too, so don’t let the “outdoor” part fool you! 

DIY Square Outdoor Coffee Table

The original outdoor coffee table has a stone top. To recreate the look, you’ll need to find a 34″ x 34″ stone piece or make the top from an alternate material. (See more ideas at the bottom of the post.)

You could use wood planks instead or a sheet of plywood or other solid surface (which could then be painted like zinc or marble or given some creative treatment like any of these DIY countertops, appropriately sealed for outdoors).

You could also pour your own concrete table top by creating a form following the instructions here and here.

How to Build an Indoor or Outdoor Wood Coffee Table Base

The outdoor coffee table woodworking plan includes 2 options to build the X base for the table: complex (for advanced builders) and simple (for beginning builders).

This is the perfect outdoor coffee table for the deck, love the X base. Build a DIY outdoor coffee table with these free plans.

The simple version of the wood coffee table base is a little more “chunky” than the original. It uses lumber that is readily available at the home improvement store, with pocket hole joinery. Recommended for advanced beginner builders.

The complex version of the coffee table base more closely matches the original inspiration table dimensions and construction. It is built using mortise and tenon joints and rough cut wood (dimensions actual 2″ x 2″ and 1″ x 2″) which you’ll have to purchase at a wood distribution store. Because it is more complex, this version is recommended for more advanced builders who are already familiar with cutting mortise and tenon joints as well as lap joints.

What size is a square coffee table?

Both versions of this woodworking plan build coffee table bases that are 34″ W x 34″ D x 18″ H (base only, tabletop will add height). This is the perfect outdoor coffee table for the deck, love the X base. Build a DIY outdoor coffee table with these free plans.

DIY Coffee Table Stone Table Top Ideas

After building the wood table base, add a 34″ x 34″ top.  Since purchasing a slab of stone can be pricy, here are a few ideas of alternate materials to the stone:

**Note that the table base may need additional reinforcement for a particularly heavy table top, such as concrete.

How to Weatherproof an Outdoor Wood Coffee Table

After building the base, you’ll want to make sure to give it some weather protection. Depending on the harshness of the elements in your area, a paint or stain meant for outdoors might suffice.

For extra protection, we recommend using a clear coat (like the drink cooler patio table) or spar varnish (like the outdoor sectional sofa). You could also try using a wood-penetrating sealer like the one used on these DIY wood countertops.

  1. Hi there,

    I’m in the process of building the Build an Outdoor Coffee with X Base Table (Simple Version). I completed the cuts on the cut list yesterday, but I have a question about the angles of the cuts for the X. Your diagram shows a 25.7 degree cut on both sides of the board but they are at different lengths on the board (2 5/8″ and 5/8″). So the 2 5/8″ angle cut can’t be 25.7 degrees can it? I’m confused. Any help you can give me before I make those cuts tonight would be awesome!! Thank you!! – Keno

    1. Hi Keno,

      No they are not both 25.7, the side with the larger cut off (2 5/8) is 64.3 (90-25.7) from the center mark on the board end. However most miter saws will not rotate all the way to a 64.3″. It’s probably best to assemble the square part of your base, mark the center of the X boards hold them in place and mark the exact lines to cut off.

  2. What color stain did you use on the x coffee table with the concrete top? It’s really nice. Thanks

    1. The table picture is actually one we purchased and then created these plans inspired by that table, so the exact stain color was from the manufacturer. Sorry I’m not more help!
