Mobile Toilet Renovation and Old Item Refurbishment

For the renovation of mobile toilets and refurbishment of old items, you can refer to the following cases and experiences, combining functional upgrades and construction specifications to achieve efficient renovation:

I. Typical Cases of Mobile Public Toilet Renovation Seven mobile public toilets on Shiji Avenue, Weifang Road, and Zhangyang Road Miaopu Road in Shanghai have achieved dual upgrades in functionality and appearance through renovation. After renovation, soft colors such as light beige and light brown are used as the base, paired with dark blue borders and local embellishments, presenting a simple and modern overall style. In terms of functional optimization, a third restroom has been added to meet the needs of the elderly, disabled individuals, and families with children. The public toilet at the intersection of Shiji Avenue and Weifang Road has set up a "Sanitation Workers' Rest Station", equipped with facilities such as refrigerators, shower rooms, microwave ovens, and charging ports, providing a rest space for sanitation workers. Such renovations balance practicality and aesthetics through modular design while reducing renovation costs by utilizing old item refurbishment (such as retaining the original structural framework).

II. Construction Period and Process for Renovating Old Bathrooms The renovation plan proposed by Jomoo divides the construction period into three categories:

1. Single-Item Renewal: Devices such as smart toilets can be replaced within 1 hour, suitable for rapid upgrade needs.
2. Partial Renovation: Partial updates to walls, floors, or sanitary ware can be completed within 6 hours, requiring prior planning of water and electricity lines.
3. Squat-to-Sit Toilet Conversion: Pipeline adjustments and installations can be completed within 8 hours, with a focus on detecting the original drainage slope and waterproof layer. Integrated services cover demolition, renovation, installation, and old item removal, reducing the coordination costs for homeowners. For example, when converting a squat toilet to a sit toilet, the original drainage outlet should be sealed first, then new pipelines should be laid, and a 48-hour closed-water test should be conducted to ensure no leakage.

III. Construction Specifications for Moving Toilet Positions According to the 2026 Home Renovation Pit Avoidance Guide, caution should be exercised when moving toilet positions:

• Original Pipeline Inspection: Use an endoscope to check for rust on cast iron pipes or deformation of PVC pipes to avoid later blockages.
• Double Protection: After wrapping the new pipeline with soundproof cotton, pour cement mortar to fix the slope.
• Acceptance Test: Observe for 30 minutes after water is turned on to confirm that floor drains and toilets drain smoothly without backflow. If the original bathroom has same-floor drainage, the moving distance is recommended not to exceed 50 centimeters; otherwise, the floor needs to be raised and pipelines rearranged, increasing floor height occupation and construction difficulty.

IV. Three-Day Rapid Renovation Plan for Old Toilets

1. Day 1: On-Site Protection
   • Lay impermeable membranes on the floor and repair damaged tiles with epoxy fillers.
   • Stick masking tape around furniture edges to prevent paint contamination.
   • Close the main water valve when removing old sanitary ware to avoid residual water leakage from pipelines.
2. Day 2: Tile Refurbishment
   • Clean oil stains on the original tile surface and apply an interface agent to enhance adhesion.
   • Roll-coat tile paint (waterproof type must be selected) twice, and after drying, apply a transparent waterproof coating.
   • Choose grout in the same color family as the tiles to enhance the overall look.
3. Day 3: Installation and Finishing
   • Before installing new sanitary ware, check if the drainage outlet aligns with the reserved hole.
   • When applying sealant, use mold-resistant glass glue and squeeze it evenly along the gap.
   • Clean up protective films and masking tape, and open windows for ventilation for more than 48 hours.

Core Principles of Renovation: Prioritize solving basic problems such as water leakage and odors before considering aesthetic upgrades. When reusing old items, assess structural safety (such as moisture-proof treatment for wooden cabinets) to avoid greater losses for minor gains.
