Portable Toilet for House Renovation

The design of portable toilets and the adjustment of toilet positions during house renovation should be carried out in accordance with actual needs and construction specifications. Here are specific plans and considerations:

I. Common Design Plans for Portable Toilets

1. Economical and Practical Model
   Featuring a gray and white metal carved panel exterior, it is designed with 8 squatting positions, separate entrance doors for men's and women's restrooms, equipped with sliding windows, stone wall lamps, and an independent water and electricity sanitary system. This design is suitable for public areas or high-traffic usage scenarios. The metal material is corrosion-resistant and easy to clean, while the independent water and electricity system prevents cross-contamination.

2. Portable Bathroom (Dry-Wet Separation Type)
   With overall dimensions of 2 meters in width and 3 meters in length, it features a pure white aluminum alloy glass single-door design, with the sink and makeup mirror placed in the external space. The dry-wet separation structure effectively prevents the spread of moisture, extending the lifespan of the equipment, and is suitable for family bathroom renovations or small commercial spaces.

3. Classic Four-Squatting Position Model
   Utilizing a multi-colored waterproof asphalt tile wall panel, it is equipped with a public handwashing area, translucent glass, and dual-basin bathroom cabinet storage functions. The waterproof wall panel adapts to humid environments, the translucent glass enhances space brightness, and the storage function increases practicality, making it suitable for outdoor activities or temporary venues.

II. Construction Methods for Adjusting Toilet Positions

1. Short-Distance Relocation
   A toilet relocator can be used to achieve short-distance adjustments of 10-30 centimeters. It is necessary to ensure that the slope of the relocator is ≥2% (i.e., a drop of 2 centimeters per meter) to avoid poor drainage. The connection between the relocator and the original drain pipe should be reinforced with a sealing gasket to prevent leakage.

2. Raising the Floor and Relaying Pipes
   If long-distance relocation (exceeding 30 centimeters) is required, the floor can be raised by 15-20 centimeters, and the drain pipe can be relaid to the new position. During construction, it is necessary to ensure that the slope of the new pipe is ≥1.5%, and a waterproof layer should be applied around the pipe, with the waterproof height covering at least 10 centimeters above the pipe's upper edge.

3. Wall-Drain Transformation
   Transform a traditional floor-drain toilet into a wall-drain toilet, achieving flexible position adjustment through a concealed water tank and drain pipe. The wall-drain toilet must be installed on a load-bearing wall or reinforced wall. The drain pipe should be made of PVC-U pipe, and 45-degree elbows should be used at bends to reduce water flow resistance.

4. Floor Opening (Requires Professional Approval)
   If cross-floor relocation is required, an opening must be made in the floor, and the drain riser must be rearranged. This method requires prior application to the property management or relevant department. During construction, double-layer waterproofing treatment should be applied around the opening, and a water stop ring should be installed to prevent leakage.

III. Key Construction Considerations

• Drainage Slope: The slope of all drainage pipes must comply with regulations to avoid water accumulation leading to odors or blockages.
• Sealing: Special sealing glue or rubber rings should be used at pipe connections to ensure no leakage.
• Waterproof Layer: The floor and wall waterproofing should be applied 2-3 times, with a thickness of ≥1.5 millimeters. A closed-water test should be conducted for 48 hours without leakage.
• Acceptance Standards: After construction is completed, the drainage speed (≥0.6 liters per second) and water seal height (≥5 centimeters) should be tested to ensure compliance with the 'Building Water Supply and Drainage Design Standard'.
