Old Toilet Mobile Renovation

Admin September 21, 2026

The mobile renovation of old toilets requires a comprehensive consideration of multiple key aspects to ensure functionality and safety.

1. Demolition and Space Adjustment
The first step in renovating an old toilet is to remove existing fixtures such as the toilet bowl and sink. If the toilet bowl needs to be relocated, the water supply should be turned off first, and the old toilet bowl should be removed and the residue cleaned up. In cases where the water pipe angle valve breaks inside the wall, professional tools are required for handling: Use a cutting machine to cut along the tile grout lines to avoid damaging the surrounding structure; if the tiles are too firmly bonded, a hot air gun can be used to heat and soften the adhesive for easier removal. After demolition, the space layout should be re-planned to ensure that the installation positions of new fixtures align with usage habits and pipe routing.

2. Pipe Relocation and Connection
Relocating the toilet bowl is a core aspect of the renovation, requiring special attention to the drainage pipes. The relocated pipes need to be precisely connected to the original main sewer pipe: For short-distance relocation, PVC glue can be directly applied for bonding; for long-distance relocation, it is recommended to use a sealing ring to connect with the main pipe and reserve a certain slope (usually 2%-3%) to prevent poor drainage or odors. If the relocation distance exceeds 50 centimeters, professional advice should be sought to assess feasibility and avoid blockages due to insufficient slope.

3. Waterproofing and Sealing Treatment
After mobile renovation, the toilet pit and surrounding areas must be re-waterproofed. It is recommended to use waterproof materials such as 'Shuibulou' mixed with water to form a paste, which should be evenly applied around the toilet pit and at ground joints, with a thickness of at least 1.5 millimeters. After drying, a closed-water test (lasting more than 24 hours) should be conducted to confirm no leakage before tiling. Additionally, pipe connections should be sealed with sealant or mold-resistant silicone to prevent moisture from penetrating the walls.

4. Case Study of Old Toilet Renovation in Urban Renewal
Taking Shanghai as an example, its urban renewal projects have addressed the issue of 'difficulty in using toilets' for residents in old housing without sanitary facilities through centralized planning and unified construction. Although such renovations are not limited to single toilet relocation, they involve common techniques such as pipe re-routing and waterproofing upgrades, providing references for household renovations: It is necessary to communicate with the property management or community in advance to confirm whether the renovation plan complies with building regulations and to avoid damaging load-bearing structures or public pipes.

Summary: The mobile renovation of old toilets should strictly follow the processes of demolition, pipe treatment, and waterproofing and sealing, adjusting the layout according to actual needs, and prioritizing the use of professional tools and materials to ensure long-term safety in use.
