DIY Bathtub Tray Step-by-Step Tutorial

Last week was our big farmhouse style bathroom reveal, and I was so excited (still am!) to be able to share with you the completion of our project. In all the excitement, I was asked several times if I would provide a tutorial for the DIY bathtub tray I made in this photo:

It’s perfect for when you need that therapeutic soak at the end of a long day for holding your bathtime essentials. Makes a perfect gift, don’t you think? With one power tool and a few basic materials, you’ll be saying, “Calgon, take me away!”

Let’s get to building, shall we?

Here is your materials list:
  • Drill/drill bits
  • 1 – 1″ x 10″ x 6′ board (can be any width you prefer and of any species – pine or hardwood) cut into length discussed below.
  • 2 – 1″ x 3″ x 8′ furring strips cut into 9″ lengths in pine or similar wood as board if staining
  • 2 – 4″ window sash handles or any type of drawer pull suitable for picking up your tray – make sure it includes screws.
  • 8 – 1½” wood screws
  • Your choice of finish (ie, paint, stain, wax or poly if waterproofing)
  • Paint brush or rag for finish work
  • Tape Measure
  • Notepad/pencil
  • Fine Sandpaper
  • Pencil
  • Builder’s Square or ruler
  • Table saw / Miter saw / Jig saw

First, let’s head to your bathroom with your tape measure and notepad with pencil in hand and you’re going to measure to the center of each side of your tub like this:

Write it down. The measurement I used for my project was 30″. Next, measure the width of the inside span of the opening of your tub from side to side like this:

My tub inner span measures 25″, and again write this down, so you don’t forget. (ask me how I know).\


Now, I want you to know that most everything I build is from reclaimed wood and I know not everyone has a mess stash like me. ahem. So, if you are using new wood for this project, just head to your local DIY store with your measurements in hand. You’ll want to grab a 1″ x 10″ x 6′ (or wider) board preferably, and a 1″ x 3″ x 8′ furring strip (or whatever width you choose) and ask them to cut it to the length you need. Home Depot has a service where they cut the wood for you for FREE. Just give them your measurements and they will do it for you. There is room for error in the project, so don’t sweat it if they’re a bit off.

As for your measurements, you’ll be telling them to cut the board to your tub width, and the furring strip to 1″ less than the width of your board. (ie. if a 10″ board, then you’ll need two 9″ pieces cut). The best part about this is your wood materials should cost a few dollars and you could make two of these – one for you and one for a gift. Yay!

*note: when purchasing lumber, always be sure to examine the board for knots, warping, etc. before purchasing. This will save you a headache later. Also, the sign will say 1″ x 10″, but the board is actually 9.5″. I know, I know head-banging moment, but it is what it is.

Before heading home, make sure to purchase the rest of your materials – your screws, handles/pulls, your choice of paint or stain, and wax or poly if you decide to waterproof your tray.


For our building purposes I’m going to be showing you two different styles of the tray – a rustic barn wood one like the tray pictured above, and a more modern style painted version. Instead of buying new wood for my examples, I am using some new wood from my stash that is an 8″ width (it’s actually only 7.5″ wide, crazy, I know.) I really like the width of my 10″ barn siding tray for a bit more room, so that is why I reference to that width for your project.

If you’d rather cut your lumber at home, just measure and mark…

…then buzz it to the size of the first measurement you got from your tub.

Grab your 1″ x 3″ (furring strips) and cut to length if not done in store already. Remember, the length you need is 1″ less than the width of your board.

Just a side note: This is my first time using our table saw since 2 years ago I buzzed my fingertips. My heart is beating, but happy to overcome it!

To make those cuts look pretty, just hand sand the edges and any rough spots nice and smooth.

Now for the fun part of this DIY bathtub tray…assembly.

To add your slats to the bottom, use this graphic as a guide.

You’re going to find the center of your board and mark lightly. Then take the inner tub dimensions you wrote down and divide it by 2. Starting from the center, measure out that length you just got and mark. That is where the outer edge of your slat will lay. The slats are to prevent your tray from moving side to side and falling into the tub.

Once you’ve got your measurements marked, take your slat and center it a half-inch in from each end, and pre-drill four holes near the ends to prevent splitting of the wood. Be sure to not drill too deep or you’ll pop through the top of your board.

Drilling Wood for Bathtub Tray |

Using your 1¼” wood screws, attach the slats to your tray bottom. Flip it over and we’re ready to add holes for the handles.

Reclaimed Rusty Window Sash Handle |

The handles I’m using came off of a gorgeous stash of wooden windows I have had for quite some time and decided to part with them. Before I gave them away (tearfully), I saw that hardware and gasped. No way was all that rusty goodness leaving my sight! I had minutes before the person was coming to pick up and my kids and I flew around with screwdrivers snatching it off. Hahaha…(Just in case, no I didn’t cheat the person, they didn’t know they were there.)


My handles measured 4″ long, but you could use knobs, longer pulls, whatever floats your boat. That’s what’s so fun about this project…endless possibilities.

Window Sash Handles for DIY Reclaimed Bathtub Tray |

Lay your handle on the tray top and center it about 1″ in from the end, and centered top to bottom. Pre-drill for what your hardware requires and then set aside the handles for now.

Adding Handles to Bathtub Tray |

Now for the finishing touches. For one of my trays, I am painting it a dark charcoal semi-gloss that I found as a seconds at Home Depot, and the other I’m using a weathered look stain, called Sunbleached by Rust-Oleum Varathane. We used it on our bedroom floor and I love the look.

Here’s a peek at what the underside should look like.

To create a water-resistant topcoat, you could add either wax or a poly finish. It’s totally your preference. Just follow instructions on the can.

For the charcoal tray, I’m using brass handles and adding a bit of text by freehand painting. If you’re not confident you can add text, just follow my tutorial on how to DIY it.

The weather tray is getting some rusty goodness and is left to look old and worn. You could add text to it too for a personal touch.


So, which is DIY bathtub tray is your favorite? The modern version with the dark paint?

Love them both! I would have a hard time deciding which one to keep so I would probably have to make two for me & a third to give away! lol
