Last Updated on April 16, 2023

When you are looking to outfit your RV with a toilet, it is important to consider whether or not a regular toilet seat will fit. While using a regular seat in an RV bathroom is possible, some key differences between the two types of seats make an RV-specific seat more suitable.

Understanding these differences can help you choose a toilet seat for your recreational vehicle and ensure a hygienic and comfortable experience while on the road. Our RV toilet guide will cover its differences, benefits, installation, and maintenance tips. So buckle up and let’s get started.

Will a Regular Toilet Seat Fit an RV Toilet: Explanation with Difference

The Differences Between Regular and RV Toilets

Regular and RV toilets have significant differences that affect their functionality, design, and compatibility with toilet seats. However, there are some important differences between a regular toilet and an RV toilet that you should consider before making a decision.

Water Supply

The primary difference between these two types of toilets is their water supply. Regular toilets constantly flow water from a plumbing system, while RV toilets rely on limited water reserves stored in the vehicle’s holding tank.


Regular toilets are designed for stationary use in homes and buildings, while RV toilets are specifically designed for motorhomes and travel trailers.

Size and shape

Another difference between regular and RV toilets is their size and shape. Most RVs come equipped with compact toilets that fit into small spaces. These toilets are typically shorter than regular ones, making them more comfortable in cramped quarters.

Flushing mechanism

Besides the way they flush, RV toilets also differ from regular toilets. Most residential toilets use gravity to flush the waste down into the sewer system, while RV toilets often use a hand or foot pump to move waste into a holding tank.

This means that regular toilet seats may not be compatible with the flushing mechanism of an RV toilet. Also, RV toilets have different plumbing connections than regular ones, affecting the type of toilet seat used.

Choosing the Perfect RV Toilet Seat: What to Look For?

Choosing the Perfect RV Toilet Seat

Several factors must be considered when choosing a toilet seat for your RV. Unlike regular toilets, RV toilets have unique dimensions and shapes, requiring specific seats. Here are some key considerations to keep in mind before choosing an RV toilet seat:

  1. Size and Shape: RV toilets come in different sizes and shapes, so measuring your toilet bowl before purchasing a seat is important. Some common shapes include round, elongated, and D-shaped. You’ll want to ensure your seat fits snugly on your toilet bowl without wobbling or moving.
  2. Material: Toilet seats can be made from various materials, such as plastic, wood, or ceramic. While plastic is the most common material for RV toilet seats due to its durability and affordability, wood and ceramic options are also available if you prefer a more upscale look.
  3. Comfort: Since you’ll frequently use your RV toilet during road trips or camping, comfort is essential when selecting a seat. Look for seats with cushioning or padding that provide extra comfort during use.
  4. Compatibility: Not all toilet seats are compatible with all types of RV toilets. Check the manufacturer’s specifications before purchasing a seat to ensure it matches your specific model.
  5. Ease of Installation: Installing an RV toilet seat should be easy enough for anyone without professional help. Look for seats that come with clear installation instructions and require minimal tools.

Investing in an RV-specific toilet seat has several benefits over using a regular one. An RV-specific seat is designed to fit perfectly on your particular toilet model, ensuring optimal comfort and stability during use.

Additionally, many RV-specific seats have features like antimicrobial coatings or quick-release buttons for easy cleaning and maintenance.

The Process of Installing a Regular Toilet Seat on an RV

In any case, if you have to install a regular toilet seat on an RV toilet, it is quite simple. Here’s how to do it:

Step 1. Remove the Old Seat

The first step is removing the existing RV toilet seat from your toilet bowl. To do this, locate the two bolts that hold the seat in place and use a wrench to loosen them. Once the bolts are loose, you should be able to lift the seat off of the bowl.

Step 2. Clean the Area

Before installing your new regular toilet seat, thoroughly clean the area around the bowl. This will ensure that no leftover dirt or debris can interfere with the installation process.

Step 3. Install Mounting Brackets

Most toilet seats have mounting brackets that must be installed before you can attach the seat. To install these brackets, simply follow the instructions provided by the manufacturer.

Step 4. Attach new seat

Once your mounting brackets are in place, it’s time to attach your new toilet seat on the RV. Simply line up the holes on your new seat with those on your mounting brackets and insert bolts through both sets of holes. Tighten these bolts using your wrench until they are snug but not overly tight.

Step 5. Test for stability:

Finally, give your new RV toilet seat a quick test to ensure it is stable and secure on top of your toilet bowl. Congratulations, you’ve successfully installed a new RV-specific toilet seat if everything looks good.

Following these simple steps, you can easily upgrade your RV’s bathroom experience with a comfortable and secure toilet seat designed for life on the go.

Tips for Maintaining Your Newly Install RV Toilet Seat

Tips for Maintaining Your Newly Install RV Toilet Seat

Maintaining your RV toilet and seat is essential to ensure it functions properly and lasts long. Here are some tips to help you keep the toilet and the seat of your RV in good condition:

  1. Clean the Toilet Regularly: It is essential to clean your RV toilet regularly to prevent any buildup of bacteria or other harmful substances. You can use a mild cleaner designed for RV toilets or vinegar and water.
  2. Use Appropriate Cleaning Tools: Use soft-bristled brushes or sponges that won’t scratch the surface when cleaning your RV toilet. Avoid using abrasive cleaners or tools that could damage the toilet bowl or seat.
  3. Check for Leaks: Periodically check for leaks around the toilet’s base and under the sink. If you notice any leaks, repair them immediately to prevent water damage.
  4. Inspect the Toilet Seat: Check the toilet seat regularly for cracks, chips, or other signs of wear and tear. If you notice any damage, replace the seat immediately to prevent further damage.
  5. Lubricate Moving Parts: To keep moving parts functioning properly, lubricate them with silicone spray or another appropriate lubricant.
  6. Use Appropriate Chemicals: When using chemicals in your RV toilet, use only those specifically designed for use in RVs. Using regular household chemicals can damage the plumbing system and cause problems.

What type of toilet is used in RV?

RV toilets are smaller than regular household toilets and measure about 14 by 15 inches in size. It is important to measure the width and length of your RV’s existing toilet seat in order to find the right size for the replacement toilet seat.

Many manufacturers offer upgraded toilet seats that can be purchased directly from them. It may be possible to use a standard household toilet seat if its measurements match that of the RV’s existing toilet seat, but this is not likely.

How do I know if a toilet seat will fit my RV toilet?

In order to determine whether a particular toilet seat will fit your RV, you should measure the length, width, and screw placement of your existing RV toilet seat.

Additionally, looking for an upgraded version of the same type of toilet seat from the manufacturer who made your original one is beneficial.

If you cannot find one from the manufacturer, then you may search for regular toilet seats compatible with your RV using the measurements taken from the existing seat. If available, it might also be beneficial to consider specially designed RV toilet seats as well.

Make Sure Your Next Trip is Comfy: Choose the Perfect RV Toilet Seat

RV travel is all about comfort and satisfaction, so choosing the right toilet seat is key. While opting for a regular toilet seat may be tempting, it’s important to acknowledge the key differences between a standard seat and one designed specifically for RVs.

Investing in an RV-specific or regular seat and installing and maintaining it properly can ensure a hygienic and hassle-free bathroom experience that will enhance your enjoyment of your travels.

Don’t overlook this important aspect of your RV setup. Choose the right toilet seat and enjoy peace of mind on your next adventure.
