Although having a shower in your RV is a great thing, only if you take good care of it. Otherwise, it becomes a problem rather than an advantage. The most common question asked by inexperienced RV owners is whether their shower has a waterproof floor and walls. However, they are also want to know how to waterproof their showers. In this article, we’ll talk about that. Let’s start!

How to Waterproof RV Shower Walls?

So How to Waterproof RV Shower Walls? First, turn off the water supply in your RV. Place the RV Shower surround on the walls, use a paint roller and squeeze the glue into the wall. Use painter’s tape and add it to the edges of the shower surround. Leave them to dry for around 48 hours, and remove them after the surface is dry.

Are RV Shower Walls Waterproof?

RV Shower Walls are Waterproof

The answer to this question is the subject of numerous discussions and disagreements among many campers in the RV forum community. The official standpoint, especially of RV manufacturers, is that RV showers are waterproof and that the vehicle owner doesn’t have to do anything to protect themselves from leaks. But some think differently, especially when it comes to older RV vehicles for which additional insulation of the walls from water penetration is recommended.

In older models of RVs and often in used vehicles that the previous owner remodeled, including the shower rooms, you can find partition walls made of Luan (also called Lauan). It is a material based on the lauan tree originating from the countries of Southeast Asia, most often the Philippines.

It is a material that has a good price, and that looks good for RV, which is why it’s popular. But one should know that when this material is used as a wall next to an RV shower, the luan wood wall is a surface covered with paper treated with chemicals. In this way, water resistance is obtained. But in the long run, it is not a waterproof material.

Why It Is Important To Have Waterproof RV Shower Walls

Importance of Waterproof RV Shower Walls

You have to keep in mind that showers in RVs are not like the ones you have at home. Water that comes out of them is weaker due to lower pressure and water consumption is limited by the amount you have in your RV tank. This means that showering in an RV can only last for a few minutes. But even those few minutes are enough to cover the sides of the shower with water.

We mentioned earlier that some RV shower walls are usually more water-resistant than waterproof. What’s the difference? Water resistant surfaces may not leak water directly, but they are still greatly affected by moisture, which causes rot and cracks.

What is the best solution to this problem? RV experts claim that installing a new shower surround is good for the vehicle not only because of the water-tightness of the walls but also because of the opportunity to refresh the look of the shower in the RV. If you are skilled in DIY projects and if you are ready to spend four to five hours decorating your RV, this is an easy job. 

Note! It is not recommended to perform this procedure on the RV during its use, but rather outside the camping season. 

Below we bring you a guide on how to install a new shower wall in an RV that will help you through the process.

Additional Installation Tips to Keep In Mind

Things to keep in mind when installing RV Shower Walls

Work Slowly

Having a shower in an RV is a big advantage. This is why many RV owners prefer RV camping over tent camping. Therefore, if the shower in your RV doesn’t work properly, your camping will not be as much fun.

Keep in mind that even the slightest water leak caused by a poorly installed shower surround in RV can cause great damage over time. When RV owners are installing a shower surround, they are usually in rush, and for that reason they miss things. Our recommendation is to take the job slowly, work with caution, and keep in mind that if you have problems with something, you can always seek the help of a professional.

Look Around

There is a really large selection of RV shower surrounds on the market. As they are all waterproof, when shopping, you should focus the most on the color that suits you best. Other important things to look for are the shower measurements, function, and price.

We recommend purchasing through an online shop because, with every shower surround option, you can find the opinion of the user, which can help you shop smart. Many RV users love to help, and their product reviews are often very useful. You can even find additional tips related to installing a surround shower with them.

Choose Quality Over Price

When choosing a shower surrounding we would all like to save as much money as possible. No one wants to spend more money than they have to. But when choosing the shower surround, don’t buy the cheapest one on the market. Cheap shower surrounds are usually not good because they are made of poor-quality material. When you install such a thing into your RV shower, you can only worsen the previous condition.

How to Avoid Yellowing RV Showers

Ways to avoid yellowing on RV Showers

Once you have installed the new shower surround in your RV, keep in mind that you have to work on regular maintenance so that you do not find yourself in a situation where the surround starts to yellow. Here we’ll give you a few tips on how you can do this. Make sure to read them carefully.

Regularly Clean Your Shower

If you want a clean white shower in your RV, be sure to clean it regularly. When we talk about RVs and cleaning, carefully choose what cleaning products you will use. Do not use strong agents, especially not those based on bleach. Rather use mild versions of detergents.

Clean Your Shower Clean Between Showers

We advise you to buy a shower cleaning spray and use it between two showers. We recommend Daily Shower Cleaner Scrubbing Bubbles. This shower spray uses the steam from the shower so you can clean it gently.

When using such sprays, you will generally have to clean your shower much less often. By using this method, you can add a SPA atmosphere to your shower! For cleaning between two showers, use a cleanser with the addition of eucalyptus which will surely help you relax and clean your sinuses well. Method Daily Shower Cleaner is a good choice.

Regularly Check Your Caulk

Remember that caulk does not last forever. They wear over time, even if you buy the best one. When this happens, the shower will start to leak. Check the condition of the caulks in your RV shower regularly to avoid unexpected leaks. When the need for re-caulk comes, it is recommended to use a waterproof silicone caulk so it can last longer.
