Easy DIY Outdoor Shower Enclosure Plans [with VIDEO!]

Have you considered adding your own outdoor shower to the exterior of your home?  It’s a great way to keep mess and moisture out of your home, cottage or beach house during the warmer months. We’re so excited to share with you our DIY outdoor shower enclosure plans and step-by-step instructions!  

Update (2023): It’s been 5 years since we made this open-air shower for our Graystone Beach cottage. It’s holding up perfectly and we’ve even built two other using the same DIY outdoor shower enclosure plans for family and friends. Read on for the full project plans and tutorial.

A sandy beach is a wonderful thing, until the sand clogs up the pipes of your septic system!

We’re so fortunate to have a cottage by the beach to spend our summer days at. The kids love it and end up coated in sand by the time we’re done.

Since the cottage is on a septic system, we’re careful to try and rinse off all the sand before using the indoor shower. However, as they’re getting older (there’s 5 of them altogether!) we’ve been brainstorming the idea of an outdoor shower stall. Not only will this minimize the amount of sand we are bringing into our cottage’s septic system, but also the amount of water it needs to filter. Moreover, it would help to reduce the amount of sand we need to clean off the floors and out of the bathtub/shower indoors.

So, when The Home Depot Canada put out a challenge for summer DIY ideas, the outdoor shower came quickly to mind.

While it seemed like a pretty straightforward project at the start, it took a bit more time and effort than we anticipated. However, over a couple of weekends and with the help of our hubbies and parents, we built a beautiful freestanding outdoor shower enclosure which the entire family will enjoy for years to come.

We’re happy to share our process for making the outdoor shower with you.

How To Build a DIY Outdoor Shower Enclosure

Step 1: Choosing the location

It took a bit of time to decide where we’d build our outdoor shower project. We wanted it to be out of the way yet have easy access to the cottage and our water source (the garden hose). Also, we wanted to ensure that there was a bit of an elevation so that the water would flow out of the shower rather than pooling inside.

We decided on this private area behind the cottage, under a large tree. The opening to the shower would face towards the hedges for a little privacy (on the right side of the photo). We measured our area (4’x6′) and marked the ground as a guide for where to dig.

Step 2: Preparing the Foundation

Then we started digging. Have I mentioned that this was one of the hottest weekends of the summer? Thank goodness we were working in the shade is all I have to say!

After a little while I called in the big guns!

Digging out the foundation took longer than we anticipated because there was quite a steep incline, and lots of roots to get through. After many hours of digging in the heat we finally got to a point where the four deck blocks were level.

We filled the pit in with gravel to level out the surface and then called in the reinforcements to stamp it all down.

We poured sand over the gravel and leveled it out before laying down some of the stone pavers for the shower floor.

And here I am relieved that we’re done for the day! (Did I mention it was hot out there?)

Step 3: Installing the 4″x4″ Posts

To provide stability to the posts for the shower, we braced around the top of the shower with 2×4’s, 3″ down from the top of the posts.

We started by measuring the distance between the outer edges of the post base on one side, cutting the 2×4 to size, screwing the two posts and 2×4 together on the ground before lifting  it all into place.

We cleared all dirt out of the deck blocks before putting the posts in.

We raised the second side of the shower and held them in place while hubby affixed the ends to tie all the piece together.

Finally we screwed the fifth post in place, leaving a 27″ wide opening for the enclosure entrance.

Once the posts were all in place we ensured that they were all vertical.

Step 4: Installing the Patio Stones

Once the posts were all in place, we decided that we wanted the patio stones to cover the entire bottom of the shower. This required carefully measuring out the corners of the stones and cutting them to slide around the deck blocks.

We cut the blocks one by one and made sure they were all leveled…

…and evenly spaced.

This again took longer than we anticipated but was well worth it. Cutting the pavers around the deck blocks will ensure they stay in place over time.

After we finished the entire outdoor shower enclosure we brought a pail of pebbles up from the beach and filled in the gaps between the paving stones.

Step 5: Framing the Shower Enclosure

It was almost time for the fun part, building up the shower walls!

We started by bracing our shower frame with 2×4’s installed 12″ from the ground around all sides except for the door opening.

Next, we cut 2×4’s in half and mounted them to the inside centers of the 4×4’s. We also screwed in a 2×2 along the center of the longest wall, to keep the fence boards from buckling.

We did need to add a spacer at the top to line up with the upper 2×4.

Step 6: Building the Walls

Finally! Time to add the fence board walls.

Our aim was to alternate the boards on the inner and outer sides of the brackets we had installed. We wanted there to be privacy yet allow for air flow.

We cut all the fence boards to size for each wall. Ensure when cutting the pieces that we left a 1/4″ space for expansion.

We cut spacers which were 2 1/2″ high and used them throughout the building process. To start, we screwed the first fence board on the outer side of the bottom 2×4 frame, lining up the fence boards with the bottom edge of the 2×4.

We secured the second fence board, leaving the 2 1/2″ gap.

We continued this all up along the outside of the shower and then repeated on the inside as shown.

Next was the second wall. We made sure that the framing was level before continuing.

Even Sonja got in on the action 🙂

This is how our shower looked with two sides completed.

We continued on to the other sides, leaving the opening for the door.

Step 7: Finishing Touches

Finally our beautiful DIY outdoor shower enclosure was nearly done and we had just a few finishing touches to go.

We installed these fancy post caps to keep the water out of the posts (and they look nice)!

We installed a few simple corner shelves for shampoos and soaps and a couple of hooks we had for clothing and towels.

We weren’t too worried about the open door as we’re in a very private area. However, for completely privacy you can add a bar with a shower curtain, or build a hinged wooden door. 

And there she is: our new private outdoor shower enclosure! We’re quite happy with how it turned out – it’s quite spacious and private. It’ll be perfect for showering after the beach without needing to go indoors.

Options for the Hot Water Supply

When we first built this outdoor shower enclosure we planned to install a Gardena Garden Shower from The Home Depot Canada to the inner wall opposite to the shower door opening. However, we realized the kids wouldn’t be happy with cold water showers.

 So next we ordered this inexpensive camp shower with a built in shower head from Amazon. It did provide some warm water but and was a great option except that there wasn’t enough water for all five kids (plus adults). Also, you need to leave the bags in direct sunlight to heat for several hours which we often forgot to do.

We also tried leaving out an extra long garden hose to be heated by the sun. This worked great until the water ran out half way through showering.  

In the end, the best thing for us was to hire a plumber who added an an outdoor hot water line to the side of the house so that we could easily enjoy our outdoor showering experience with hot water on demand. 

We are so excited to get to use this new addition to the Graystone Beach cottage. If you are curious about some of the updates we’ve made to the inside spaces, be sure to check out our beach-themed bathroom , coastal bedroom decor ideas and coastal kitchen makeover.
