I have been checking out beautiful DIY corrugated metal showers on Pinterest for a while now. After an extensive plumbing issue, we had the opportunity to turn awful into awesome with this beautiful shower and bathroom reno.
Today I am super excited to unveil the fabulous shower that Big Jon built for me!
I have previously shared with you the plumbing issue/water disaster we had here at the Funny Little House. What I didn’t tell you was that this awful problem turned awesome when we had to 🙁 tear out the old, ugly shower in order to get water to the bathroom!
In this situation, one could choose to be like, “Oh, woe is me…. We have another expense here at the house and seriously, how did this home become such a money pit.” Or perhaps one might respond with a resounding, “Yes! It’s finally time to redo this ugly, old, 1970’s bathroom! Hello, lemonade!”
Which do you think I chose?
Yup – new decor for the shower! Yeah!
Check out the before pics.
I will say that we previously had painted and updated the vanity. We also removed the glass shower door and the blue toilet.
While I enjoyed the red, the paint had never adhered properly. It remained sticky and sort of odd for the past 5 years or so. Why would I pass up an opportunity to fix this problem also?
Big Jon wanted to add some pine board to the bathroom, to tie it together with the other areas of the house. Choosing a paint color proved to be a bit difficult as the floor tiles have a bit of gray in them, the shelving a golden pine, the white shower pan and of course the corrugated metal shower.
We chose Cloud Cream by Behr. It is bright and fresh and mixes well with silvers, grays, and the pine.
Back to the DIY Corrugated Metal Shower
I searched and searched Pinterest and the internet for a complete tutorial and only found one that actually had any type of directions. We used it as a guide as we attacked our shower project. Here goes!
Supplies:
- 8 foot corrugated metal panels – we needed to 6 for our 36 x 36 shower
- flashing (for the corners)
- Pole barn screws – these special screws will seal the shower tightly at the screw sights
- caulk – we used a clear bath and shower caulk
Step 1: Rust Prevention
According to the tutorial, we were to spray the corrugated panels with Rustoleum to prevent any type of future rust from happening on the metal. While we did try to do this, the clear coat just beaded up and wiped off of the metal. I guess it was already coated properly so we just skipped that step!.
Step 2: Metal Panel Installation
Big Jon attached the metal panels to the walls overlapping as needed. This was quite an adventure because of course, the shower stall is not square either vertically or horizontally. 🙂
So he measured, remeasured and measured again. He really tried to measure multiple times in order to cut only once. This mostly worked.
Big Jon said that it was difficult to cut straight on the metal, but by using a diamond blade, he managed to get the panels to fit properly and the holes to line up with the proper plumbing. I’d say that is a win! 🙂
I’m pretty sure that cutting the holes for the fixtures was the hardest part. That whole measure and remeasure thing, right?
In retrospect, we should have installed more 2×4’s to attach the metal to. This would have made it so much easier to place the screws in a really cool pattern. Oh well.
Step 3: Flashing
Flashing was installed in each of the corners so the shower would not leak.
Big Jon said that the flashing was not as easy to work with as he thought it would be. It is a little flimsy and does not crease like a nice sheet of paper. But he made it work. He is pretty awesome, like that. 🙂
Step 4: Caulk
Caulk was applied around the corners and the plumbing fixtures to prevent any water from seeping through the openings.
This is my favorite picture. It is how you find Big Jon in the midst of any given project. Standing. Looking. and Thinking. We are such a unique pair when it comes to projects. Big Jon thinks and thinks and then acts. I act and act and then think. Hmmmm.
For example. I thought I would surprise him with hanging the shower curtain for him. Favorite Third and I set out to cut the metal and install the pipe rod. We measured and drilled and hung the shower curtain….. about 2 inches too low.
We will be working this little error out in therapy for the next few years. LOL. Not really. Lucky for me, Big Jon is also very forgiving and I am an excellent problem solver. I have found a solution, to raise up the shower curtain without replacing ALL of the corrugated metal! We just haven’t done it yet.
For now, the DIY corrugated metal shower works just fine as is!
How cute is this cute little birdie picture?
Step 5: Trim
The final steps include trimming out the panels with some beautiful pine. I love it! I am so lucky that I have these fun ideas and Big Jon helps me make them happen 🙂 This shower is beautiful, functional and everyone loves it!
What do you think? Do you enjoy the DIY corrugated metal shower? I love it! It is like a breath of sunshine when you walk in the house. So bright, clean and inviting!

This is so cool, Paula! I love this idea and the rustic look.
I abSooooLutely love it Paula. We were only brave enough to put a corrugated metal door in our bathroom because we couldn’t find the right instructions on how make it water and rust proof. Great job you guys
We tried to coat it with some Rust-Oleum but it would not stick so we decided to just leave it and see what happens. So far so good!
