Have you got the summer blues? Well then, it is the perfect time to clean the dust off your RV and go on a refreshing road trip with your family. After all, nothing solves boredom better than a road trip experience through the country. But before you even think about setting off on your adventure, you must prepare your RV for the troubles you might face ahead.
We are talking about a thorough inspection of the entire vehicle. Things like checking the tires and readying the engine. But, most importantly, waterproofing the RV’s floor and shower walls.
RVs that come with a shower cabin isn’t usually waterproof. They are water-resistant, and resistance only works for so long. When the barrier breaks water leaks into the other compartments, spoiling everything in its way.
Ways you can waterproof the walls and floors of your RV’s shower cabin
But before you begin, use masking tape on the edges to avoid painting any unwanted areas. Once you have taped the edges, use a roller to cover the larger part of the walls and a small paint brush to fine-tune the difficult areas. As soon as the paint dries, you can have a worry-free shower in your RV.
Moreover, if the paint starts to come off one area, you can re-do the specific section without painting the entire cabin. Not only does that save money but also your valuable time.
The panels come in various materials, like acrylic and PVC. You can choose the one you like best, but we’d recommend going for the acrylic option since it is strong and sturdy. Moreover, acrylic panels are resistant to cracks and fading. So, it’s one of the best options for those looking to save money.

Step by Step Waterproofing Process
The aforementioned materials will protect you and the RV from getting dirty. In other words, it would be less of a cleanup job for you after the waterproofing.
For Waterproof Paint:
Use the roller to spread the paint evenly in the entire shower cabin area.
Use the paintbrush to reach the difficult corners and cover the cabin entirely.
If there is a need, you can go for a third coat, but it is not usually needed.
For Waterproof Paneling:
Remember to keep the measurements accurate to the last centimeter, or else an entire panel could go to waste.
Acrylic works the best, but it is a bit expensive. In that case, you could go with PVC or wood.
If you still find it difficult, ask a friend to help or hire the help of a professional. You could also search the internet or watch videos on YouTube for advice.
Sealing the Gaps
You should leave no gaps unsealed, except the one at the bottom. The small crevice is there to allow air behind the panels. But why is that important? That is because the air flowing behind the panels helps them dry. It also prevents the build-up of harmful bacteria. The last thing you want is mould and other fungi developing behind the shower walls. Not only are there health risks, but they also make your RV smell bad.

How To Seal Walls?
You will need caulking to seal all the seams and crevices in the shower area. Caulking is usually silicone-based, and it holds well against any kind of water pressure. Thankfully, RVs do not have too much pressure, so you shouldn’t worry too much.
Once you have applied the caulking, you must wait for a few hours to let it dry up. Then you can start enjoying showers worry-free!
