Step 3: Install Higher-Grade Showerhead

Installing a higher-grade showerhead will provide more pressure and a better feel to the shower. Make sure to read the installation instructions carefully and ensure that all parts are properly installed. If there is enough space, walls can be expanded to increase the shower’s size.

This step requires cutting into the existing walls and framing new walls. Make sure to secure the new walls to the existing frame for stability.

Step 4: Install New Shower Floor

To make more room, a larger shower floor can be installed. This involves using appropriate waterproof material and ensuring that it is level with the rest of the shower area. If there is room, additional shelving can be included in the shower to provide more storage space. Expanding the shower walls and floor is a great way to make the most of the extra space.

Step 5: Install Larger Drainpipes

Larger drainpipes should be installed to help keep up with increased water flow. This will help keep the shower from overflowing and reduce the risk of flooding. Depending on the available space, additional faucets can also be added to the shower in order to provide more water pressure and control over temperature. Be sure to use appropriate parts and follow all installation instructions.

Step 6: Seal Any Gaps

Once all components are installed, it is important to seal any gaps in order to prevent water from escaping the shower area. This can be done by using a waterproof sealant or tape. Before using the newly expanded shower, it should be tested. Run the water in order to check for any leaks, and make sure that the shower is functioning properly.

Keep Your RV Shower Clean and Well-maintained

Making your RV shower bigger isn’t difficult, but it requires some skill to ensure a safe and successful installation. Keep these tips in mind as you complete your project so that you can enjoy a bigger and better showering experience in your RV.

How Can You Maximize the Amount of Water Pressure in a Larger Shower Area? 

Installing a high-pressure pump is one way to increase the water pressure in a larger RV shower area. This type of pump can be installed directly on the existing RV plumbing system, and it can help to deliver more water pressure to your shower. You should also check that all the joints are tightened properly so that there aren’t any leaks in the system.

Finally, if your RV plumbing system is too old or corroded, you may need to replace it with a new one for improved water pressure.

In addition to installing a high-pressure pump, another way to increase the water pressure in a larger area is by using an inline booster pump. This type of pump can be installed directly on the existing RV plumbing system, and it can help to deliver more water pressure to your shower.

The inline booster pump works by pushing the excess air out of the pipes, increasing the amount of water available in each shower area.

How Can You Ensure That Your RV Shower Stays Well-maintained? 

It’s important to keep your RV shower well-maintained if you want it to stay comfortable and spacious. First, ensure the water pipes are kept in good condition. This includes checking for any cracks or leaks and replacing them as needed.

Additionally, inspect all the seals around the shower doors and walls to ensure they are properly sealed. Finally, keeping the area around your shower clean and free of debris is essential. This will help prevent any potential slip-and-fall accidents as well as keep the water flowing easily without clogging up the drain.

You should also consider investing in a good-quality shower curtain to protect against mold and mildew buildup. Regularly cleaning the shower area can also help keep it looking its best and smelling fresh.

Regularly Cleaning the Shower Area

It’s also important to make sure that your RV shower is properly ventilated, as this will help it remain comfortable while in use. Installing a fan or exhaust vent to draw out moist air from the shower can go a long way in keeping the area dry and free of odors.

Is It Necessary to Hire a Professional to Carry Out This Project? 

As with any project on your RV, it depends on the individual’s skill set. If you are comfortable with basic DIY projects and have some knowledge of plumbing and carpentry, then a professional may not be necessary for making your RV shower bigger.

However, if you require help with this project, it is best to hire someone with experience in dealing with the plumbing and carpentry associated with RVs. Recognizing that this project will likely involve some complex work, hiring a professional will ensure the job is completed effectively and safely.

When hiring a professional, it is important to ensure they are qualified for the job. Ask for references if possible, and check for reviews online too. Additionally, make sure to ask the professional about their experience in dealing with RV projects specifically.

Ensuring that you hire a qualified professional will save time and money in the long run, so make sure to do your research before making any decisions.

How Much Will It Cost to Make Your RV Shower Bigger? 

Making your RV shower bigger can greatly add value and convenience to your vehicle while camping. However, the cost of expanding your RV shower will depend on the size expansion you are looking for and the materials that need to be purchased for the job.

If you are looking to make a minor adjustment in size, such as adding a small shelf or extending the length of the shower curtain, then you can expect to pay around $100 in materials.

Adding a Small Shelf

However, suppose you are looking for major size expansions, including relocating plumbing and electrical lines, purchasing new fixtures, and fitting new drywall or tile. In that case, you should expect to pay up to $2,000 or more. It is important to take into consideration the cost of materials, labor costs, and the time it will take to complete your size expansion before making any decisions.

What Type of Sealant Should You Use to Make Sure Your RV Shower Stays Secure? 

When attempting to make your RV shower larger, it is important to use the correct type of sealant in order to ensure that everything stays secure and watertight. The most common types of sealants used for this purpose are silicone-based caulk, polyurethane foam sealant, and waterproof tape.

Silicone caulk is the most popular choice for RV shower expansion because it adheres to both smooth and porous surfaces, seals quickly, and remains flexible. It’s also good at preventing water damage down the line. 

Polyurethane foam sealant is a great option if you need to fill in large gaps or crevices, as it expands to fill the spaces and creates a watertight seal.

Waterproof tape is ideal for keeping your shower secure around corners or other non-flat surfaces, as it contours without losing adhesion. It’s best used in conjunction with other sealants since it can’t provide enough protection on its own.

Whichever sealant you use, clean the area and properly apply it so your shower is secure. This will prevent water damage in the future and ensure that your RV stays dry and safe for years to come.

Keeping Your Shower Secure Around Corners
