RV Toilet Sizes And How Much Weight They Can Support

Having a good toilet is important when buying an RV. If you are going to spend a week camping, having a comfortable toilet makes things a little more relaxing. There are many different options for RV toilets, and the size and weight capacity can vary from model to model.

Many different sizes of RV toilets come installed into RVs and are available for purchase separately to replace the old one or add on if needed. The typical dimensions of an RV toilet are 14.75 inches wide, 19.25 inches tall, and between 12 to 16 gallons of water capacity, depending on your chosen model.

Will a regular toilet seat fit an RV toilet?

The short answer is that a regular toilet seat can fit an RV toilet if compatible. The height of the toilet seat isn't affected by the size, so it will remain at around 14 inches high regardless of what kind you have installed. However, how wide a regular toilet seat fits might be an issue if your RV's dimensions are smaller than normal or if there has been some wear and tear on them from age.

The width of the bowl does vary, though, between 12 inches to 16 inches, depending on which model you go with. So, keep that in mind when shopping for a replacement toilet seat or simply buying an extra one. If it is too wide, then your regular-sized seat won't be able to fit snugly onto it and may even slip off when you sit down.

If it is too narrow, then slipping off will also be an issue, plus the seat won't feel as secure and might even rattle when in use which can become annoying rather quickly. Therefore, make sure to measure before buying a new toilet seat, and if possible, try out the one that's already there to see how it feels.

If the bowl is a bit small, your regular toilet seat might not fit snugly and could even slip off. On the other hand, if it's too narrow, you'll have issues with how secure it feels. Plus, there will be rattling when in use, which can quickly become very annoying. So again, make sure to measure before buying, just in case!

Can you put a bidet on an RV toilet?

A bidet is a small sink that you can use to clean yourself after using the toilet. It's becoming more popular in North America now as westerners are starting to become used to this method of hygiene. It has several benefits, especially if your RV lacks one or doesn't have high enough water pressure for an efficient flush with every use.

In terms of installation, you can have a bidet added onto any RV toilet regardless of the size with proper plumbing modifications. Of course, you'll need a T-adapter for the waterline and some extra piping but other than that, everything else is like a regular installation.

As long as you have the right equipment and know what to do, adding in a bidet is very simple. But, of course, you'll need some extra piping for it with everything else like normal.

If your RV toilet is too small to fit a bidet, or you don't want it there, then no problem! We just need some extra piping and equipment for the installation.

Can you upgrade an RV toilet?

Yes, you can upgrade your RV toilet if it is too small for your liking or does not operate to your desired level. You may do this by adding a holding tank and pump system, so flushing becomes much more accessible than manually doing it all the time.

The holding tank is an excellent addition as it saves water and does not take up extra room. It will need to be hooked up with piping along the side of your RV, but this allows you to use fresh water for flushing, which means less strain on the system itself, plus no dirty toilet bowl!

You can also choose from different toilet models of different heights, widths, and styles to fit your specific needs. You can then maximize the power of these by using an RV converter which will provide you with more options on how much water is needed for flushing along with higher pressure, so it all happens faster than before.
