Thetford 31646 Aqua-Magic V Toilet Review and Buyers Guide

In this day and age, one of the best ways to get out of the house and enjoy what’s around you is by going on a road trip. Although many people only have the financial capabilities to stuff everything they have in their car to enjoy a trip on the road, some people are fortunate enough to have an RV. Think of an RV like a hotel on wheels, allowing you to save money since you can sleep right in the vehicle instead of staying at a hotel.

In fact, some people will retire into an RV in their later years, allowing them to travel very freely without any possible hindrance from their normal life. Still, the RV life isn’t perfect as many people raise questions about how they can go to the bathroom in one.

When it comes to actually go to the bathroom, simplicity tends to be the most attractive option toilet-wise, since no one wants to do anything too complicated in the ordeal. Thus, why it really interested me to see this model toilet from Thetford be so versatile compared to other RV toilets.

In fact, it’s incredibly versatile to the point that it’s suited for all recreational vehicles, making it a perfect option no matter your RV situation. I loved the Thetford 31646 parts and how the single-hand system worked for the unit.

Rather than do anything too complex or out of the ordinary, it worked very beautifully with its single-hand system, allowing you to only press it halfway to add water to the bowl or all the way to flush it. Unlike some RV toilets, it offers a 100 percent bowl coverage flush.

It has a tremendous textured lid, which sheds water and resists any scuffs very quickly. Without sounding too grotesque, feel-wise, it felt like a toilet you would use at home, which is very difficult to find in an RV toilet.

Weight-wise, it’s incredibly light, meaning you can easily install and remove it whenever you need to. My only real issue with the toilet was its height since it felt a bit too compact for me. However, this is a very minor issue and can be seen as a positive since it took up less space.

Price-wise, this is an incredibly fair-priced toilet for what it does and is a perfect option for an easy installation for your RV. Overall, it’s hard to find a better RV toilet at this price, and the height issue is very minor and will work no matter your size.


  • The single handle system works well and allows you to add water or do a full flush easily.
  • Comes completely set-up and easy for you to install.
  • Great build quality and lid that rids any potential scratches from occurring.
  • Excellent company that’ll answer any questions or concerns you might have.


  • It’s a bit compact and small.


As far as RV toilets are concerned, it’s very challenging to find a better toilet than the Thetford 31646 aqua magic v toilet. Although its compact-size might be a minor nuisance, you’ll get used to it a lot quicker than you think, and its functionality is superior to anything else.

Utilizing information like this can do you wonders in your search for the best RV toilet. Obviously, the review above should be more than enough for you to take a closer examination of the subject, but a buyer’s guide should propel you over the top.

What’s an RV Toilet?

For those who don’t know, an RV toilet is precisely what it sounds like, a toilet that’s meant for an RV. Considering there’s an ever-growing list of people becoming interested in an RV, many of the needs associated with an RV have to do with a toilet.

Whether you’re aware of it or not, there’s a lot of need for people to have a toilet in their RV. Considering people take RVs out for long road trips, you’re going to need the ability to go to the bathroom whenever you can.

Besides having a typical bowl you can actually go in, an RV toilet plays a vital role in how durable it is, it’s flushing capabilities, and how it actually works. All of these factors should be looked at closely, so you don’t accidentally purchase an RV toilet that’s not up to the standards you need.

How Does an RV Toilet Work?

Generally speaking, an RV toilet operates similar to a standard toilet with how you use it. However, they tend to be a bit smaller and compact, allowing you to easily install them without the heaviness associated with a traditional toilet.

The main difference between a standard toilet and an RV toilet has to be where the actual feces or urine goes. Rather than be shot down into the sewer, an RV toilet typically flushes it down into your RVs septic tank or its own septic tank. Either way, the septic tank will need to be emptied at some point, otherwise, it can get backed up.

As a result, it’s a good rule of thumb to be aware of what’s going on with your RV toilet and how backed up it can potentially. Always look closely at how long it can last without being emptied since it’s always an important area of concern with this subject.

What to Look for in an RV Toilet

Similar to every other subject, there’s a lot of information tied to an RV toilet that you should be aware of. Considering there’s so much attached to this matter, you might as well take the time necessary to see what some of these different factors are. Nevertheless, let’s take a look at what these aspects are:


Like you can imagine, the material of an RV toilet is incredibly important not only for its comfort but for durability. Plastic is the most common for RV toilets since it’s very light, but it tends to be a bit easier to destroy in the long run. For a sturdier but heavier and expensive option, porcelain is excellent to consider. Lastly, there are a few wood options in the RV toilet world.


Right next to the material associated with an RV toilet comes the need for weight. If you want to install your RV toilet easily without any hassle, obviously, a lightweight is better. However, if you’re looking for one to last a bit longer, usually the more decadent the toilet, the better in this regard.


No matter how financially stable you might find yourself to be, everyone has a budget, and it needs to be looked at when it comes to an RV toilet. For the most part, you can find an excellent RV toilet for roughly $100 to $200, but don’t be afraid to spend more if you can afford it. Realize, whatever you end up investing into your RV toilet is what you’ll back in return quality-wise.
