If you’re looking for a portable RV toilet, the Camco 41544 Travel Toilet might fit the bill. This model has a larger seat than some of the other portable toilets on the market. The larger seat makes it a good choice for heavier people.
A bonus is this portable toilet has a sliding gate valve between the freshwater and wastewater portions of the toilet. This valve closes securely holding odors inside the toilet. The valve isn’t the only feature that helps with the smells. So does the ABS resin interior of the portable toilet.
The spring loaded latch makes transporting the toilet to empty it easier to do without accidents. However, if you let it get full before you empty it, you will have to lift approximately 56 pounds. When it’s empty it weighs approximately 11 pounds, which is rather light for a portable toilet.
- Convenient waste removal
- Supports up to 330 pounds
- Low capacity waste tank
The Camco 41544 Travel Toilet is our choice if you want a portable toilet. Portable toilets are good for more than just RVing. Use it in a tent, a van, or on a boat. This one has a wider seat, so heavy people should find it to be relatively comfortable.

This toilet is available in two heights, standard and low profile, so you can choose which is most comfortable for you.
The Dometic 320 series is a gravity flush RV toilet. The nice feature associated with that is that it has a foot pedal for flushing, so it’s a hands-free operation. You press the foot pedal part way to add water, and completely to flush.
Installing this unit is easy, and it’s backed with a 10-year warranty. This RV toilet is available in both white and bone, so you can choose the one that best fits your decor. The ceramic bowl is relatively easy to clean and the exterior ceramic is scratch-proof.

The Nature’s Head Self Contained Composting Toilet is the only composting toilet on our list of favorites. If you’re wondering what’s so different about a composting toilet, you might be surprised to learn this one uses absolutely no water.
So, if you’re looking for an organic, eco-friendly way to handle waste in your RV, this is the toilet for you.
While it doesn’t require water, it does require electricity to power the fan that is incorporated into the unit. This composting toilet is virtually odor-free with some customers reporting they sometimes smell soil, but the fan helps eliminate that smell.
The Nature’s Head RV toilet is made of durable plastic. It separates solid waste from liquid waste and has self-contained composting features. The waste holding tank is large enough that you could wait weeks before emptying it, which is perfect for off-grid camping.

The Dometic 310 series RV toilet is in contention for the best RV toilet because it is a residential style toilet with maximum water efficiency and performance in mind. This toilet is offered in both standard size and low profile models, so you can choose whichever feels most comfortable to you.
An ergonomic foot pedal operates the flush mechanism. This toilet features a gravity flush system which is similar to the system in your toilet at home. To let water into the toilet you press the foot pedal part way, and then push it fully to flush.
The flush capacity on this toilet is powerful, yet it only uses approximately a pint of water to operate. The water consumption is quite economical for a standard size toilet. Plus, the standard size provides you with adequate hip and knee space to be relatively comfortable.
- Gravity flush toilet
- Ergonomic foot pedal
- Tall, ergonomic seat
- Full-sized slow-close seat
- No spare parts available
The Dometic 310 series RV toilet is one of our contenders for the best RV toilet for heavy person because it gives the feeling of an at-home toilet while you’re on the road. The standard size is comfortable for taller people, and the gravity flush mechanism is more like you’d expect at home.
Weight Capacity: 300 pounds

If you’re a taller person, the high profile version of the Thetford Aqua-Magic V is a good choice for you. However, if you’re shorter, but still heavy, you might consider the low profile version. Even the high profile version is a compact RV toilet for ease of fitting into almost any RV.
The Aqua-Magic V is a lightweight RV toilet that is easy to install. This isn’t compact in the sense of small and dainty. It’s compact in the sense that it fits in a smaller space. It’s made of durable plastic that makes it easy to maintain as well as lightweight.
Like several of the other models we’ve discussed, the Aqua-Magic V lets water partially into the toilet with a partial depression of the flush lever. Then, it fully flushes when the lever is depressed completely. The toilet is not only comfortable, but also secure.
- Comfortable for taller people
- Easy to install
- Removable toilet seat
- Not water efficient
The Thetford Aqua-Magic V is a lightweight RV toilet that has both a high profile and a low profile version. The low profile version is ideal for a shorter, heavy person. The high profile version is better for a taller, heavy person.
Types of RV Toilets for Heavy People
Before I started research for this guide, I thought an RV toilet was an RV toilet. The only RVs I had ever been in already had a fully functioning toilet, so I gave very little thought to the style of toilet. Imagine my surprise when I learned there are at least six types of RV toilets!
A gravity flush RV toilet is similar to a residential toilet, but it doesn’t have a water tank. Since it doesn’t have a water tank, it must be connected to an outside water source. Otherwise, it will only work when the water pump connected to the RV holding tank is on. You flush this kind of toilet with a foot pedal and use a lever to fill it with water.
A macerating flush toilet breaks down waste before transporting it to the black tank. These toilets have blades that cut and crush waste before it enters the holding tank. This means the waste is much more fluid in the tank. When waste is less solid it helps cut down on the smell associated with it.
Combining macerating blades and a vacuum pump, a vacuum flush toilet thoroughly removes the waste from the toilet bowl. The vacuum makes the flush mechanism more powerful. The macerating blades help to liquefy solid waste, which as we’ve learned helps decrease the smell of the waste.
A composting toilet is different from others in that it doesn’t use water. These RV toilets separate liquid waste from solid waste. If they’re used properly, they don’t smell bad, however, they can smell like soil. An air vent helps carry the smell of soil outside. These toilets are ideal for a couple or individual, but not for a family.
Portable Toilet (for camping)
A portable toilet doesn’t separate solid and liquid waste. This kind of toilet produces raw sewage. Because there is not a water source connected to a portable toilet, you will see and smell any sewage in the toilet. These kinds of toilets must be emptied frequently into an RV dump or another toilet.
A cassette toilet is similar to a portable toilet, but it’s fixed in place. Typically, you can access the waste tank of a cassette toilet from outside your RV. You will see and smell waste when you empty your cassette toilet.
A bidet is a type of toilet that uses a stream of water to help you clean your bottom after doing your business. If you’re interested in this type, check out our reviews on bidets for obese people.
Features to Consider
When purchasing an RV toilet, you should consider a variety of features. We’ve compiled a short list of the three top considerations. Our list is not all-inclusive. We suggest creating your own list of the features you’d like in an RV toilet to help you with your shopping experience.
The material of the RV toilet plays a vital role in the durability of the toilet. An ABS resin model, while not as durable as porcelain, still holds up well under normal use. There are some porcelain models available for RVs if you want a true home-away-from-home bathroom experience.
If you are replacing your RV toilet, it’s important to be aware of the size you need. RV bathrooms are close quarters, and if you select the wrong size toilet, you could face a situation where your new toilet simply doesn’t fit. For this reason, you should take careful measurements before selecting your new RV toilet.
Look for an RV toilet that offers superior sanitation and sealing features. Does the toilet flush easily and completely? Does it have enough power to thoroughly remove waste from the toilet bowl? The flapper, valves, and connectors should all seal tightly to help prevent leakage and odor.
Can I use a residential toilet in my RV?
You can’t use a residential toilet in your RV primarily because the flushing mechanism and water capacity are different. The two types of toilets don’t work the same, so they aren’t interchangeable.
Do I need special toilet paper for my RV toilet?
The RV septic system is more delicate than your home system, so it’s best to use toilet paper specifically designed for your RV. In a pinch, for example, if you run out while camping and the nearest store doesn’t have RV paper, you can use regular paper, provided it disintegrates in water.
How can I make my RV toilet smell better?
If you have a smell emanating from your RV toilet, you likely need to clean your tank. The first step is to get rid of any clogs, then thoroughly clean the tank and treat it with Spic and Span or PineSol and water, finally, thoroughly clean the toilet and flapper making sure the flapper closes properly.
Do RV toilets have a weight limit?
Like residential toilets, RV toilets do have a stated toilet weight limit. Typical RV toilets can hold up to 300 pounds, so most people can use an RV toilet without issue. Some we’ve reviewed here will even hold up to 400 or 500 pounds.
What is the largest RV toilet?
Due to limited space, when we talk about large RV toilets, we are generally talking about height. The tallest RV toilet we’ve heard of is 19.5 inches tall.
Conclusion – Best RV Toilet for Heavy Person
If you’re like me, you never really considered RV toilets that much other than the utilitarian use for them. However, after doing research for this article, I’ve discovered there is more than one type of RV toilet. The differences are related to the way the toilets flush as well as the style of the toilet itself.
Like with residential toilets, you should consider the size, material, and functionality of the toilet when choosing the best RV toilet for you. We have chosen five contenders for the best RV toilet for heavy person. This guide is just a starting point to help you narrow your choices.
