Converting a Bed Car into a Mobile Toilet

There are several main methods for converting a bed car into a mobile toilet:

Using a Car Toilet

This is a relatively common and convenient modification method. There is a type of car toilet that is an upgraded electric version of ancient chamber pots, with a shape similar to that of a toilet in an apartment bathroom. It has the function of automatically packaging excrement, but using this function usually requires an additional fee; if not, manual packaging is required. When using it, place the toilet in front of the seat and adjust the position of the front-row seats to provide suitable space for use. In addition, some people choose not to use smart car toilets but instead use garbage cans lined with eco-friendly plastic bags. This method has a lower cost, but when using it, it is necessary to choose eco-friendly bags and find a suitable place to bury the excrement for natural degradation to avoid environmental pollution.

Making a Simple DIY Device

Some people attempt to make simple urination devices. A common method is to combine a bottle with a tube, insert the tube into the bottle, place the bottle outside the car, and then urinate inside the car through the gap in the car door. However, this device has some problems. For example, if the tube is too thin, it is difficult to accurately urinate into the bottle. To solve this problem, some people have improved the device by cutting off the head of the tube to enlarge the aperture, but a new problem arises: the tube becomes too soft, causing the excrement to flow out slowly and affecting the user experience.

Other Ideas

Some people also consider making an opening in the chassis of the bed car and designing it in a style similar to a squat toilet on a train. When not in use, the opening is closed, and it is opened when needed. However, this modification method requires a relatively high level of experience in bed car modification and certain professional knowledge and skills to ensure that the modified squat toilet is safe and convenient to use and does not have an adverse impact on the overall structure and performance of the bed car.
