The bathroom is the space most closely related to frequency of use and health among the 'golden kitchen, silver bathroom.' This Skill organizes the essence of the bathroom topic in the Xi'an Renovation Classroom knowledge base in reverse order (newest first), covering the full chain of pitfall avoidance for wet-dry separation, waterproofing, floor drains, tile grouting, tiles, bathroom fixtures, washbasin cabinets, toilets, showers, windowless bathrooms, bathroom heaters, and more.
Core Principles (Remember These 5 First)
- Wet-dry separation is the baseline for health: it is not a shower partition; the toilet and the washing area must be separated. An external washbasin cabinet is the minimum standard.
- If waterproofing is done wrong, rework after move-in is inevitable: waterproofing in the wet area of the bathroom must be applied to sufficient height and in enough coats; the doorway, pipes, and floor upturns are key points.
- Floor drains and drainage determine the user experience: if the floor drain position, slope, or drainage pipe diameter is wrong, flooding everywhere will be an everyday occurrence.
- Tile grouting, tiles, and bathroom hardware must be judged by 'daily living': slip resistance, dirt resistance, and ease of cleaning are a hundred times more important than appearance.
- Windowless and small bathrooms especially need design to compensate for shortcomings: daylighting, ventilation, and moisture resistance—none can be missing.

How to use
When users ask about renovation issues for related spaces (whether or not construction has already started), first locate the reference file according to the topic above, then give suggestions based on the specific layout/budget. Key points:
- Give conclusions directly: first say "what not to do," then say "what should be done."
- When it involves alterations (knocking down walls, changing doors, changing drainage), be sure to remind them to first confirm whether it is a non-load-bearing wall, property management policies, and the waterproofing scope.
- When it involves safety (electricity use, slip resistance, child safety), use a self-check checklist format so users can troubleshoot accordingly.
- Do not remove the AI flavor; use the "everyday life" tone of Xi'an Renovation Classroom, speak plainly, and provide practical value.
