What to Consider When Buying the Best RV Toilet for Heavy Person – Buying Guide

Like buying any product from the market, there are some essential factors and information to consider to determine the best toilet for your RV. So, before you hit the market in search of the best RV toilet for heavy person, here are some of the things you need to consider before making an informed decision about buying one for your RV bathroom.

Type of Toilet You Want for Your RV

Fortunately, there are quite a few different types of RV toilets. Let’s see what are these different types you can consider choosing your best RV toilet for heavy person.

Gravity Flush RV Toilet

The gravity flush is the most common type of RV toilet and just as the name suggests, it employs a force of gravity to push waste down into the holding tank. These RV toilets operate in the same manner as most residential home toilets and come with a simple design that makes troubleshooting easier in case of a clog.

Macerating Flush Toilet for RV

The macerating flush toilet for RV features motor-powered blades that break up waste into small particles before being flushed down into your RV’s black water tank.

Vacuum Flush Toilet for RV

The vacuum flush toilet is similar to the macerating types since it also breaks down waste into smaller particles. However, it breaks down the waste using its vacuum pump to liquefy waste before flushing it down into the black water tank.

RV Cassette Or Cartridge Toilet

The RV cassette or cartridge toilet is designed to permanently connect to your RV but contains a cassette holding tank just like a portable toilet that requires to be emptied whenever it is full. However, the holding tanks on these types of toile are a bit small.

With an average capacity of about 5 gallons, it means that you will require emptying often into a residential toilet or public restroom. Although there is a bit more work on emptying, you can be sure less waste is being held in your RV and potentially smelling up.

Portable RV and Camping Toilet

Portable camping toilets are often used in small camper vans or cab-over campers because they come with smaller waste holding tanks that are light enough to be emptied into a residential toilet or public restroom when filled up.

Portable camping toilets are designed with two parts that are hooked together. The bottom tank is for holding waste while the upper container is for holding flushing waste and adds up as a toilet bowl. When the waste holding tank is full, it can be detached for easy emptying and cleaning.

Composting Toilet For RV

The RV composting toilets are designed to be for more environmentally friendly and off-the-grip RVers. Owing to their design, the smell isn’t a problem with these types of toilets as long as they are used and functioning as required.

These toilets don’t use water to flush down the waste into the holding tank thus saving you water which can be scarce, especially in remote camping sites. The toilet works by separating liquid and solid waste before the latter is converted into compost that can conveniently be deposited into the soil.

The composting toilets are a perfect choice for RVs that are permanently parked on a farm or sustainable property.

Plumbed-in or Portable

RV toilets are available in two main varieties; plumbed-in or portable. The plumbed-in RV toilet versions are designed for permanent installation in RV bathrooms, connected to the water tank, and are emptied into the onboard waste tank. As such, they are more like the regular home toilets and are said to be the most comfortable. Besides, they don’t require emptying as often.

Portable RV toilets on the other hand are not plumbed-in. Therefore, the waste is flushed into a waste holding tank that requires emptying more often. Moreover, they are the most versatile and can be used almost anywhere and not just in an RV. However, they are smaller and less comfortable.

Between these two versions, the plumbed-in models are said to be the most ideal version, especially if you want a permanent solution for your RV. But if you are looking for a more flexible RV toilet unit, then a portable toilet version could be your perfect choice.

Toilet Profile

RV toilets are available in two main profiles: high profile and low profile. As you could perhaps imagine, the high profile RV toilets are taller than the low profile ones. The ideal toilet profile choice you intend to buy boils down to personal preference.

However, since most RV bathroom spaces tend to be a bit tight and you are a taller individual, you might find comfort in a high profile. But if you are shorter, you would probably prefer a low-profile toilet for your RV.

This way, you won’t have your feet dangling while sitting on a high-profile toilet. Besides, an RV toilet is often mounted on an already elevated place above the main floor of your bathroom. As such, be sure to take this extra elevation (or lack of it) into account when choosing the right profile for your new RV toilet unit.


Most portable toilets for RV are made of plastic materials. And if you are up to ensuring you choose the best RV toilet for heavy person, you have to choose one that is made of strong and durable plastic that will last more under your heavyweight and several trips.

Plumbed-in RV toilets, on the other hand, are made either from plastic and ceramics materials. While ceramic varieties are strong, sturdy, and durable, there are equally more luxurious. However, you have to contend with the higher prices that they come with.

Flushing Mechanism

Most RV toilets come with either a hand-lever or a foot-pedal flushing mechanism. Both of these flushing mechanisms feature a 2-in-1 function that allows you to fill the waste holding tank before emptying.

However, this is different with a composting toilet or a portable toilet. The main advantage of the hand-lever mechanism is that it allows the user to reach it easily to fill the bowl or pre-flush before wiping. However, the downside of this hand-lever mechanism is that they are a little more brittle and susceptible to breaking if not used carefully.

Foot-pedal flushing mechanisms tend to be a bit more durable and don’t often require you to bend down to access the hand lever. However, they are a bit harder to use when sitting on the toilet, since they tend to require more force to depress.

Most composting and portable toilets for RVs also come with some type of built-in flushing mechanism or hand sprayer to allow easy cleaning of the bowl after use. In the end, the choice of which flushing mechanism suits your RV bathroom, without a doubt, boils down to personal preference.

Space Available

The amount of space you have in your RV bathroom can determine the kind of RV toilet you will buy. When looking for a new RV toilet or want a replacement, don’t forget to measure the dimensions of the space within your RV bathroom.

Therefore, the length and width of the toilet are some of the most important dimensions to consider before buying a new toilet for your RV. Equally, consider whether you require space to pull a lever on the side of your toilet or access the behind for an easy installation process.

Height and Size

The height and size of the RV toilet are very essential considerations. Generally, a larger and higher toilet will be more comfortable and convenient to use. However, if you have a limited RV bathroom space, a too large toilet can make your bathroom feel overly cramped.

However, if you have a small RV bathroom space, you have every reason for choosing a small-sized portable toilet rather than getting a larger plumbed-in toilet option.


Durability is an essential factor to consider when it comes to buying an RV toilet for heavy person. Regardless of the model you want to buy, durability should be a key factor especially when it will have to support heavy weight at least once a day. Therefore, make sure that the RV toilet you want to buy is well built to be sturdy and durable.

One of the best ways to determine that an RV toilet is durable is through reading the customer reviews. Customers will mention any problem with the construction of the model and make it evident whether or not the unit is of high quality and durable to support the rated weight.

Bear in mind that reading the product description isn’t enough. Therefore, move to the customer review section and see what they say concerning the toilet model’s durability.

Easy to Install

The installation process of the RV toilet you want to buy is equally an essential factor to consider. Besides, what is the need to buy a well-made toilet with high-quality features but you can’t figure out how to install it.

The determining factor of whether or not the RV toilet you intend to buy is easy to install is the size. The bigger the size of the unit, the difficult it is to move it around during the installation process. However, it is crucial that you look at the installation manual before buying your RV toilet.

Some manufacturers provide an installation manual with images and instructions. Besides you can look at customer reviews to see whether there are those who have mentioned the installation process or do some research by googling.


The main issue that most RV toilet users bring forth is their comfortability. Most models come with a bit smaller seat that isn’t enough for a normal-sized person to sit on it comfortably, let alone a heavy person.

Given that you want an RV toilet for heavy person, it is essential that you find a toilet with a wide seat enough to accommodate your heavy person. Without a doubt, nothing is unpleasant than having a unit with an uncomfortable seat in your RV.

So, when buying a toilet for your RV, it is important to buy a unit with a seat that is wide enough for you to sit comfortably. Enameled wood toilet seats are some of the most comfortable toilet seats you can have for your RV toilet.

Frequently Asked Questions

Q: Can I use an RV toilet in my house?

A: Just like the name implies, an RV toilet is designed for use in a recreational vehicle and camper. Granted, it is quite uncommon to use it for residential purposes, even though it is possible.

Q: Can I use a regular house toilet in my RV?

A: Yes, it is quite possible to use a regular residential toilet in your RV. However, it is not commended due to certain concerns. The first thing to bear in mind is that the flush tank of a residential toilet is quite heavier than the ones designed for use in RV.

Once you have poured some gallons of water into the tank, press the flushing valve. Dump the RV toilet chemicals that can be either in liquid or tablet form. Once you do that, you can be sure your toilet s ready for use.

Q: How can I make my RV toilet smell better?

Q: How can I replace my RV toilet?

A: Replacing your RV toilet doesn’t always require the help of professionals. In fact, it is possible to replace your RV toilet all alone. So, let’s get into it!

First, shut off the water supply in your RV. You can do this by flushing your RV toilet to reduce the pressure applied to the water supply line. Take off one or two plastic covers surrounding the base of your toilet. Removing the cover will reveal at least one bolt which you will unscrew.

Don’t lift the toilet when unscrewing the bolt. Reach the hose attached to the topmost back portion of the commode found behind the toilet. place a cloth under the parts to soak the water that drips out. Proceed to unscrew the hose and then lift the toilet out of the floor. Pull it up straight while ensuring the bolt is kept upright while resting on the floor.

Replace the rubber gasket with a new one. The gasket will seal your new RV toilet into the floor. Once the gasket is well settled, place your new RV toilet in a firm manner to prevent it from shaking around. Line up the holes before screwing down the bolts to hold the toilet firmly on the floor.

Once done, inspect the toilet and ensure it does not shake when you sit on it. If it is wobbling, then you can tighten the bolts a little until it is firm. This should complete your RV toilet replacement process.

Q: How to use an RV toilet?

A: RV toilets work the same way your home toilet work except that the waste holding tank is smaller and removable for easy regular emptying. There are external sewer systems designed for this purpose.

The RV toilet features a seal on the base of the toilet bowl that works to keep the odors from the waste holding tank from seeping up into your recreational vehicle. To flush an RV toilet, you only step on the pedal that is often located in the front or at the side of the toilet unit. The seal will open while the water is pumped into the bowl to flush down the waste.

Q: Do I need to use RV toilet paper?

A: An RV toilet paper is designed for use in RVs simply because it disintegrates more easily than regular toilet paper. As such, it prevents clogging up in your RV sewage system. Regardless, some RVers contend that using regular toilet paper still works well. So, the decision to either use RV toilet paper or regular toilet paper is entirely based on personal preference.

Q: How can I fix my clogged RV toilet?

A: A clogged RV toilet is one thing you don’t want to handle because of the filthy it comes with. However, fixing a clogged RV toilet is not as complex as you might think. The usual cause for a clogged RV toilet is clumped toilet paper.

So, before you call your plumber to RV toilet fixing, try to fix the clog by opening the valve and pouring hot water down. The hot water will help break down whatever is causing the clog. You can also use chemicals that are designed to fix toilet clogs. However, be sure that the chemicals you use are septic safe!

Q: Why does my RV toilet bubble when I flush?

A: For a properly functioning RV toilet, the air is removed when you add water into the black tank. The air often exits through the vent, but if your toilet starts bubbling, this is a sign that the vent isn’t working properly. The vent isn’t allowing the air to escape from the black tank.

If bubbling is a common occurrence in your RV toilet, you notice when the tank is full, there is a high probability that there is a problem with the vent’s pipe. It is penetrating too far down into the black tank. As such, the pipe no longer allows the air to escape when the water is covering the pipe’s opening. The air otherwise goes back to the tank thus causing bubbling.

But if bubbling is a constant issue, then you possibly have a clog in the vent. This problem can arise from letting the tank get overwhelmingly full to cause the waste pill up and form a clog in the vent pipe.
