Are RV Toilet Seats All the Same? A Buyer’s Guide

After spending a lot of time on the road in your RV, things start to wear down, including toilet seats. Upgrading your RV toilet seat makes a huge difference in the overall feel of the RV (and your bottom). You want to be very careful when choosing toilet seats because they are not created equally.

RV toilet seats are not all the same. There are different sizes, shapes, materials, and features (i.e., raised, cushioned, slow-closing, etc.). Some seats require other mounting hardware and different placements of nuts and bolts, so they won’t fit every toilet model.

Today, the RV industry offers hundreds of replacement toilet seat options, many with their own unique features. Read on to learn more about RV toilet seats, our four favorites, and how to pick one that’s right for you. And if you are in the process of building your van, check our van build resources page here to have plenty of useful information.

What To Consider When Choosing an RV Toilet Seat

A toilet seat is a personal decision that requires some care and thought before choosing one. You should get one that fits your bottom comfortably, is easily cleaned, and fits the look of your RV.

Let’s take a closer look at the three primary factors that you need to consider when choosing an RV toilet seat: 

Sizes of RV Toilet Seats

RV toilet seats are not all the same size, and different models offer different shapes and dimensions. There are elongated and round toilet seats, seats explicitly made for RV toilets, and seats made for residential homes.

Take time to measure your current toilet seat before choosing a replacement. 

Do this by removing the toilet seat, flipping it upside down, and measuring the broadest area (the center) from outer edge to outer edge.

If you’re still unsure about which toilet seat will fit your RV toilet, unscrew the seat and take it with you to the hardware store to cross-reference the fit. What if you don’t want to carry a toilet seat around the hardware store? 

Trace the toilet seat and hardware onto a piece of cardboard and bring it along.

RV Toilet Seat Materials

The material of your toilet seat affects the comfort and quality. Most RVs come with a flimsy, thin plastic toilet seat that many owners switch out as soon as they own the vehicle. Below, we’ll discuss three of the most common materials for RV toilet seats.


While porcelain is one of the more popular materials for residential toilets, it’s not a common material for RV use. Porcelain is fragile, and when you’re constantly driving and hitting bumps, this material takes a beating. In addition, porcelain is very heavy and tends to be more expensive than other RV toilet seat materials.


Most RVs come pre-fitted with plastic toilet seats. Plastic is the most commonly used material for RV toilet seats because it is lightweight, inexpensive, and easily replaced. Plastic does, however, tend to wear down pretty quickly.


Because of its durability, enameled wood is a popular option for RV toilet seats. Wood, however, tends to be heavier and more expensive than plastic. You also want to think about when the enamel wears off–what if you get a splinter in your bottom? That might require a bit of explaining when you’re in the ER.

RV Toilet Seat Features

RV toilet seats are not limited to the standard, flat, flimsy plastic you’re accustomed to seeing in RVs. There are dozens of toilet seats on the market, each with its own features, with some of the most common features having slow-closing lids and cushioned, raised, or heated seats.

Can You Use a Regular Toilet Seat on an RV Toilet?

Most RV owners agree that the toilet seats at home are much more comfortable than the standard RV toilet seats. RV toilet manufacturers try to duplicate the look and feel of residential toilet seats with their designs, but can you install a residential-sized seat on an RV toilet?

You can use a regular toilet seat on an RV toilet if the model is compatible. Most standard toilet seats are around 15 inches (38.1 cm). Check your manual for specifications, and if a residential toilet seat matches your toilet’s dimensions, your toilet is suitable for a residential toilet seat.

Residential-size toilet seats tend to be less expensive than RV toilet seats, despite typically using more materials and hardware.

Some RV toilet seats have raised “housing” areas on the back to conceal the water breaker (depending on your toilet model). Residential toilet seats do not usually contain these housings and the breaker may stick out a few inches if you use a residential toilet seat. 

This is a purely cosmetic issue, but if it bothers you, you’ll benefit from choosing an RV toilet seat that offers the breaker housing.

Reducing Stress on RV Toilet Seat Hinges

To reduce stress on the hinges of your new toilet seat and to help it last longer, you might also consider adding extra “bumpers” to the underside of the seat. 

Bumpers reduce the amount of weight put on the hinges, thus increasing their life span. Most expensive seats come with these pre-installed, but you can add more with a sliced rubber hose and some heavy-duty glue.

It’s better to glue the bumpers instead of drilling them, as this further weakens the material. Make sure the bumpers are aligned with the edges of the toilet bowl so they can work their magic.


If you spend a lot of time in your RV, you want it to be as comfortable as possible. When enhancing comfort in our space, sometimes we forget about the bathroom! 

To make your RV bathroom more comfortable, start by investing in a new RV toilet seat.

From sizes and features to colors and shapes, RV toilet seats are not all the same. Use the information in this article to pick one that’s right for you.
