How to Install a Mobile Toilet

Admin October 07, 2026

The installation of a mobile toilet can be divided into two scenarios: standard installation and relocation installation. Here are the specific steps for each:

Standard Mobile Toilet Installation

  1. Unpacking and Inspection
    Upon receiving the toilet, immediately open the package and carefully check the list of accessories to ensure all components (such as the toilet body, water tank, sealing ring, fixing bolts, etc.) are complete and undamaged. If any parts are missing or damaged, contact the supplier promptly for replacement or reshipment.

  2. Assembling the Water Tank and Toilet Body
    Align the water tank with the toilet body through the dedicated interface, ensuring a tight fit at the connection. Some water tanks require pre-installation of the inlet and outlet valves, which should be adjusted to the appropriate positions according to the instructions to prevent subsequent leaks or drainage issues.

  3. Installing the Sealing Ring
    Place a sealing ring (usually made of rubber) at the connection between the toilet's drainage outlet and the floor drainage pipe, ensuring the sealing ring fully covers the edge of the drainage outlet to prevent sewage leakage. If the floor is uneven, adjust the position of the sealing ring appropriately or use silicone sealant for additional sealing.

  4. Securing the Toilet
    Slowly lower the toilet onto the floor drainage pipe, ensuring the drainage outlet is in full contact with the sealing ring. Insert the provided fixing bolts through the holes in the toilet base and screw them into the pre-embedded nuts in the floor, tightening the bolts gradually and alternately to prevent the toilet from tilting.

  5. Connecting the Water Supply Pipe
    Connect one end of the water supply hose to the water inlet of the water tank and the other end to the wall-mounted water valve, ensuring the connections are secure. Open the water valve to check if the water supply to the tank is smooth and observe for any leaks at the connections.

  6. Testing and Adjustment
    Before first use, flush the toilet multiple times to test its drainage function, observing the drainage speed and checking for blockages. If drainage is slow, check if the drainage pipe is blocked by the sealing ring or foreign objects, or adjust the position of the toilet to ensure the drainage pipe is aligned.

Toilet Relocation Installation (Requires Prior Planning)

  1. Measuring the Relocation Distance
    Use a tape measure to determine the distance between the original drainage outlet of the toilet and the target location, establishing the required length of the relocation device. The greater the relocation distance, the steeper the drainage slope should be; it is recommended to maintain a 5% slope (e.g., raise the pipe by 5 cm for a 1-meter relocation) to ensure smooth drainage.

  2. Cutting and Assembling the Relocation Device
    Based on the measurement, use a saw to cut the main body of the relocation device to the appropriate length. Connect the main body, elbows, and other components of the relocation device using specialized adhesive, ensuring a leak-proof seal at the connections.

  3. Cutting the Floor and Securing the Device
    Cut a groove in the floor (slightly wider than the relocation device) and embed the relocation device in the groove, securing it in place. If using a flat-pipe relocation device (approximately 50-60 mm in height), the groove should be about 20-40 mm deep; subsequently, level the floor and tile it to match the final floor height, minimizing the need for excessive floor elevation.

  4. Installing the Toilet
    Follow the standard installation steps to secure the toilet onto the relocation device, ensuring the drainage outlet is aligned with the relocation device. Some newer relocation devices feature a flange that can be directly connected to the mounting base on the main body and fixed to the floor with cement, simplifying the installation process.
