Best One Piece Toilets in 2019 – Reviews & Complete Buying Guide

Comfortable, Odorless, Sanitary and Affordable

Firstly, evaluate how big is your RV and whether you would like to have or several toilets. If you are aiming at installing a second toilet then you might want to consider a vacuum one or a macerator toilet for your second unit as these models do not need to be placed exactly above the liquid waste tank.

Instead, the waste can be pumped up to 20 meters away through the sanitation hose to your waste tank.

Secondly, evaluate the amount of space you have in your bathroom and whether you can fit a full-sized toilet in there.

Also, sit and think about whom you are most likely to travel and whether you are going to have small children or elderly on board because low-profile toilets that are not installed on a platform will be hard to climb for them.

Moreover, try to avoid toilets that come with a foot-pedal flush and instead look for toilets that have the traditional flush wall switch or handle on the side of the water tank.

Furthermore, think about how often you are going to travel and for how long as well as how often you are going to have a chance to dump your waste tank.

Do You Travel To Remote Places?

How often are going to find yourself away from electrical power and water supply? If the answer is often then you might want to consider investing in a portable toilet or cassette toilet as they work independently and have water tanks that you can pre-fill.

How To Avoid Bad Odors?

Often, the problem of stinking toilets lies in the waste holding tank that is located directly below the toilet.

Because the toilet opens up right above the tank this allows the odours to rise and fill the RV bathroom.

The solution to this problem can be the installation of a vacuum or macerator toilet as they can be installed without direct contact with the waste collecting tank.

Moreover, in gravity-flush toilets, the water in the bowl acts as a barrier between the air in the bathroom and the odour in the sanitation hose.

However, you would need to regularly check the seal and the flush ball to ensure that the valves stay clean and that water does not leak out or down the bowl.

Keep a close eye on the mineral buildup such as watermarks because this can damage the water seal.

Also, regular tank treatments will help prevent bad odours as well as the spread of bacteria. Plus, pay attention to good ventilation regardless of the season.


In conclusion, I would like to say that no matter what toilet model you will decide on, the most important thing to do is to regularly clean the toilet with all the sanitation tubes.

Plus, keep a close eye on the black tank to make sure the gate valve is not clogged and if it is then call a plumber immediately. Till then, do not use the toilet to avoid a potential pipe burst.
