Home Second-Floor Mobile Toilet

The design, procurement, and layout adjustment of home second-floor mobile toilets should be carried out in accordance with actual needs and standard operations. The specific plan is as follows:

1. Double-Layer Structure Design Case Reference

If you need to build a second-floor mobile toilet by yourself, you can refer to the two-story structure case that combines a mobile toilet with a sunroom. This type of design usually features an orange and gray spliced exterior, with the exterior wall material being thickened galvanized corrugated board painted, and the frame using thickened and reinforced galvanized square steel welding, combining aesthetics and durability. This type of structure is suitable for outdoor or semi-outdoor scenarios. It is necessary to ensure that the load-bearing capacity of the second floor meets building safety standards and to reserve drainage and ventilation pipe interfaces.

2. Purchase Recommendations for Finished Mobile Toilets

There are various brands of home mobile toilets on the market, such as Tianlan Sanitary Ware, Mengyang, and Lvshi, with materials covering stainless steel, aluminum-plastic panels, and anti-corrosion wood, supporting customization and having a wide price range (from 300 yuan to over 1000 yuan per set). When purchasing, the following functions should be focused on:

• Waterproof performance: Prioritize overall waterproof design or waterproof materials with an IPX4 rating or above to avoid the risk of water leakage on the second floor;
• Sound insulation effect: If it is close to the bedroom or living room, it is recommended to choose a double-layer sound insulation structure or add sound-absorbing cotton;
• Ventilation system: Equipped with an exhaust fan or natural ventilation openings to prevent odor accumulation;
• Size adaptation: Choose a compact type (e.g., 0.8m×1.2m) or a standard type (1.2m×1.5m) according to the space on the second floor, ensuring that the door width is ≥70cm for easy access.

3. Key Points for Layout Adjustment of Second-Floor Toilets

If you need to change the position of the original toilet, choose a plan according to the drainage method:

• Same-floor drainage (sunken toilet): The pipes can be directly changed, but a new waterproof layer (thickness ≥1.5mm) needs to be made, and a drainage slope of 2%-3% should be reserved;
• Inter-floor drainage:
  • Pipe shifter: Suitable for short-distance shifting (≤2 meters), and a special adhesive should be used to seal the interface;
  • Wall-mounted toilet: Lay the drainage pipe along the wall to reduce floor trenching, but the hidden space for the water tank should be planned in advance;
• Sealing enhancement: All pipe connections should be coated with waterproof glue, and a closed-water test (water storage for 24 hours without leakage) should be carried out;
• Anti-blocking measures: Avoid using 90° elbows, prefer 45° oblique tees, and regularly clean the pipes.

Precautions: The renovation of second-floor mobile toilets should comply with the Construction Specifications for Residential Decoration and Renovation Projects. If it involves changes to load-bearing walls or major adjustments to the drainage system, it is recommended to entrust a professional team for construction.
