Mobile House Toilet Design

There are various designs for toilets in mobile houses, with the following common types:

I. Water Storage Tank-Modified Toilets The large water storage tank is split vertically into two halves. Universal wheels are installed at the four corners of the bottom wooden board to enable mobility. The tank body is raised with wooden strips to form a basic framework. An opening is cut on the side as a doorway, and a door frame and transparent plastic soft panels are installed to form the walls. The top is covered with waterproof material to form a roof. Inside, drainage pipes are configured to connect to the toilet (which can be a water-saving or dry toilet), a small water tank, a bathroom heater, and a washbasin. The drainage from the washbasin can be connected to an independent water storage container or discharged directly. This design is cost-effective and suitable for temporary use scenarios. However, the water storage container needs to be cleaned regularly, and the space utilization is limited by the shape of the tank.

II. Standardized Mobile Toilets They consist of a fecal sewage storage tank (or treatment device), a floor, sanitary ware, walls, washing equipment, a water tank, a roof, and a mobile device.

• Structural Classification: A single-unit structure is an independent unit, while a composite structure is composed of multiple modules.
• Mobility Methods: The lifting type relies on lifting equipment, the handling type requires manual or mechanical handling, the powered type is equipped with an engine for autonomous movement, and the trailer type can be connected to a vehicle for towing.
• Sewage Treatment: The water-flush type needs to be connected to a water source. The non-water-flush suction type transports feces through a vacuum pump. The recirculating water-flush type uses a filtration and disinfection system to reuse water. The dry-pack type uses degradable bags to collect feces. This design is suitable for public places such as scenic spots and construction sites and requires a professional maintenance team.

III. Dry-Wet Separation Mobile Bathroom Integrated Units The overall dimensions are usually 2 meters wide and 3 meters long, with a pure white exterior and an aluminum alloy glass single door. Inside, a partition divides the space into dry and wet areas: the wet area is equipped with shower facilities and a waterproof floor, while the dry area has a washbasin, a makeup mirror, and storage cabinets. The drainage system uses floor drains connected to pipes, and some designs integrate electric water heaters and exhaust fans. This design has high space utilization and is suitable for long-term family use. However, pipe connections need to be reserved, or water storage and power supply equipment should be provided.

IV. Solar-Powered Mobile Toilets Based on the modification of a water storage tank, solar panels are installed on the top to supply power for lighting, exhaust fans, and small water pumps. The toilet adopts a dry design, and feces are transported into a sealed storage tank through a screw conveyor, reducing water consumption. This design is suitable for remote areas without grid coverage but is greatly affected by light conditions. It requires a backup power supply or a manual exhaust device.
