Container House Bathroom Renovation
When renovating the bathroom of a container house, it is essential to focus on five core aspects: floor treatment, drainage system, sealing treatment, separation of water and electricity, and ventilation and dehumidification to avoid structural damage, water leakage, and safety hazards.
1. Floor Treatment: Rust Prevention and Waterproofing Are Fundamental
The bottom of a container is made of steel, which is prone to rusting and perforation when exposed to moisture over time, leading to a decrease in load-bearing capacity. Before renovation, thoroughly remove rust and apply anti-rust paint to form a basic protective layer. Then, lay a 20mm thick cement mortar leveling layer to ensure a flat surface. Finally, cover it with a waterproof membrane to create a double waterproof barrier. For higher durability, stainless steel drainage channels can be welded to guide water flow to designated areas and prevent water accumulation from eroding the floor.
2. Drainage System: Slope and Pipe Diameter Are Key
The internal space of a container is limited, so the slope of the drainage pipe should be ≥2% to ensure rapid drainage of sewage and prevent blockages. The pipe diameter should be selected as PVC pipes with a diameter of over 50mm to enhance drainage capacity. During construction, holes should be pre-drilled in the side walls of the container to avoid damaging the structural stability by cutting later. The drainage outlet can be directed outside the container for centralized treatment, reducing the risk of internal leakage.
3. Sealing Treatment: Details Determine the Anti-Seepage Effect
The connection between the wall and the floor is a high-risk area for water seepage. Neutral silicone structural adhesive should be used to seal the corners and baseboards, and waterproof adhesive strips should be pressed in to enhance sealing. A water stop ridge of 5-10cm high should be set at the corners to effectively block water penetration. In addition, all joints should be repeatedly checked to ensure no omissions and avoid long-term leakage due to poor sealing.
4. Separation of Water and Electricity: Safety Distance Cannot Be Ignored
The high-temperature and high-humidity environment of a shower room is prone to water and electricity accidents. Electrical wires must be laid in pipes and concentrated in the top area of the container, away from water sources. Water supply and drainage pipes should be routed along the bottom or side walls, maintaining a minimum distance of 30cm from electrical wires. It is recommended to use splash-proof sockets and waterproof switches to further reduce the risk of electric shock.
5. Ventilation and Dehumidification: Improving the Enclosed Environment
Containers are highly enclosed, and moisture tends to accumulate, leading to structural rusting and a decline in air quality. Forced exhaust fans and active dehumidifiers should be installed to accelerate air circulation. Louvered vents should be reserved on the walls to create natural convection and reduce moisture retention. Regularly check the operating status of ventilation equipment to ensure its effective operation.
Case Warning: During the Nagoya Asian Games, the bathroom of a container house occupied by athletes once leaked due to poor sealing under the sink, resulting in severe water accumulation on the floor. This case highlights the importance of sealing treatment and drainage system design. During renovation, details should be strictly controlled to avoid similar problems.
