Building a Picnic Table in One Day

When we were getting our yard ready for spring, we took a trip to our local landscaping center to look at their plants.

On their patio, they had an array of beautiful outdoor furniture. Eileen sat down at a picnic table she liked, looked at the price (a very high $450), and said to me, “I bet you could make this.”

I nodded, thinking about all of the creative things Eileen and our son do in our yard, like having backyard picnics, bubble-making, and painting.

Having a DIY picnic table in the middle of the backyard would be perfect.

Plus, I’m always up for a good woodworking project.

Researching Picnic Table Plans

I did some research online on how to build a picnic table and ended up choosing the first one that came up – PopularMechanics.com.

It seemed simple to construct and the design plans were of a high caliber. The best part was that this picnic table plan called for using composite decking for the tabletop and seats.

This eliminated any concerns I had about having to use pressure-treated wood in close proximity to foods or having to spend time staining or sealing the surface of the DIY picnic table.

Cleaning the composite decking on the picnic table would be a cinch too. It was a little more expensive than using real wood, but it was worth it.

The rest of the wooden picnic table (legs and supports) would be regular pressure-treated wood, so costs would still be low overall.

The specifics of how to build a picnic table are outlined pretty well on the source website, so I’ll just recap my picnic table building experience.

Overall, it was quite a fun project to work on. Best of all, I accomplished it all on a Saturday (albeit a long Saturday from morning to night).

DIY Picnic Table Material Order

I printed out the materials list from the website. Then I placed an order on Lowes’ website for in-store pickup.

I normally don’t like doing store pickup for lumber because you are at the mercy of whatever employee is selecting your wood.

This usually means a random assortment of quality, with crowning knotty boards.

Money-Saving Tips

However, I found an awesome deal on eBay for multiple $15 off $50 Lowes coupons, and they were valid online only.

Using an Excel spreadsheet, I distributed all the materials across 4 separate orders to total just over $50 each.

​Then I purchased 4 of the coupons on eBay for a mere $4 (coupon codes were emailed to me immediately after purchase) and placed four Lowes store pickup orders. Just $4 on eBay saved me $60. Not bad! The Lowes guys didn’t mind when I went to pick up the order either.

Here’s my car full of wood after the lumber excursion to Lowes (ignore the concrete and the pipes – they are for an upcoming shade sail project):

Fitting Everything for the DIY composite Picnic Table in the Car

I did have to get some wood cut in the store for the picnic table. I ordered several 12 ft pieces of composite decking and I knew that wouldn’t fit in my car.

So I had an employee cut them in half for me. Having the store cut your wood is convenient, but it’s not always worth it.

Their cuts aren’t that accurate, and sometimes you have to wait a while to get help.

Additionally, there seems to be a trend starting in stores to charge you for too many cuts.

Always thinking of how I can save money, I brought a measuring tape and a handsaw in case I decided to cut the picnic table wood myself in the parking lot.

As it turned out, a thunderstorm appeared out of the blue when I got to Lowes. That forced my hand and I had to have them cut it for me. They usually charge 75 cents for the cuts, but they waived it.

How To Build A Picnic Table

The first step in my how to build a picnic table project was to cut all the wood. So when I got home, I spent an hour cutting all the wood according to the plans. This hard work resulted in the picture below.

​Doesn’t it look like a kit just waiting to be put together?

The next step in building a picnic table is to put together the picnic table’s legs:

Here comes the tabletop support:

Next up was the pair of seat supports for the DIY picnic table:

Here are the five pieces of the picnic table project that would soon come together to form the table’s skeleton:

I clamped some of the pieces together and the picnic table project was now three dimensional:

With the seat supports attached, it was starting to look like a picnic table now:

Here I used a diagonal support beam to prevent the picnic table’s legs from shifting inwards:

Here I had to reinforce the structure with some 3.5″ galvanized carriage bolts to support the weight of people and tabletop loads:

It wasn’t too early to take the DIY picnic table for a test drive.  Here I am taking a break from the work:

Finally, the crowning moment of the project came when I attached the composite decking to the DIY picnic table.

I highly recommend using a countersinking bit for pre-drilling the holes for the deck.  I believe they make special screws for composite wood, but I didn’t have any.

At first, I used regular deck screws, and without a countersink bit. However, they did not look good after the head penetrated the wood.

Unlike real wood that compresses under the screw head, the composite material made a really ugly blemish on the surface.

​After trial and error, I found the countersink bit did a wonderful job carving out a notch for the screws.

I used my router and a round-over bit to smooth/bevel  the edges of the deck wood:

Finally, I completed the DIY picnic table. Eileen helped me move it into the backyard. It was extremely heavy, but that was just a testament to its quality.

Here’s what the picnic table looks like in its element (notice our garden planter and rain barrel in the background).

The total cost of this professional quality DIY picnic table ran us $140. That’s after a $60 discount via the $4 eBay coupons.

I estimate a pre-built picnic table of this quality would have cost a few hundred dollars in the store. It would have been even more at the landscaping stores!

Our DIY picnic table is already getting a lot of use and is sure to be a hit at our next BBQ.

    I want one!! Love the stain on the top!

  2. Thanks, Christine! It was so easy to make! The top is actually the color that the composite deck came in. They had a variety of colors to choose from but we loved that one!

  3. Dave Bustos says:

    I really like your design here. It looks sturdy. Its just the plan I’ve been looking for to build for a good friend that asked me if I knew of a sturdy design for a picnic table.
    Great job and I enjoy reading your blog.

      Thanks, Danielle! We love it – and I still can’t believe Ash made it in a day!

  9. Wow! I am super impressed. My hubby is very good with wood projects but we’ve never tackled an outdoor table. The back of your van does look like lots of times when we’ve come home from one of the big box stores! Thanks for sharing at Over the Moon.

    1. Eileen @ Just Measuring Up says:

      Aww thanks so much, Shelley! Since your husband is good with wood projects, I’m sure he would do a great job! 🙂 We are happy to help if you have questions. Haha – Ash keeps trying to trade in my sudan for a pick-up truck, but I won’t let him since we always (somehow) get everything in the van 🙂 Have a great week!

    1. Eileen @ Just Measuring Up says:

      Thanks Jess – would love too! 🙂

  10. Mother of 3 says:

    Looks lovely! We have an old picnic table that is falling apart and seriously needs replacing. At this point I think the paint is holding it together. Definitely pinning this page for when it’s finally time to make a new one.

    1. Eileen @ Just Measuring Up says:

      Thanks, Joanne! Hahah we have furniture like that too! We have an old wooden swing that needs a total replacement. It’s hard to get everything checked off the to do list 🙂 Thanks for pinning!

  12. Sandra Garth says:

    One of our picnic tables is at least 35 years old and has seen it’s better days. This would be a great project for my husband. I hope he thinks so too!

    1. Eileen @ Just Measuring Up says:

      Haha I hope he thinks so too! We have furniture like that too 🙂

  13. creativejewishmom/sara says:

    very impressive and yes, great for doing activities with kids out doors, good for you! thanks for sharing on craft schooling sunday. Just by the way, I once had a similar table that actually folded up to become a 2 seater outdoor couch, a very hand piece to have in the yard as well!

    1. Eileen @ Just Measuring Up says:

      Oh Sara, I love that idea!! I’ll have to add that to Ash’s list! I love when furniture is versatile like that 🙂 Have a great week – thanks for the party!

  15. What a fantastic job! I wish we had the time and tools to make a table like this with composite decking. We’re on our second cheap wood picnic table, and they are such a pain to paint and stain each year! Thanks again for sharing at the #happynowlinkup!
