Bathroom renovation involves careful planning, especially when it comes to structural work, waterproofing, plumbing, and electrical systems. As reported by Beijing News journalist Li Feishe, attention to detail is essential to avoid potential hazards. The high humidity and frequent water exposure in bathrooms make them one of the most critical areas for safety during home decoration.
Unlike other living spaces, the bathroom presents unique challenges due to its moist environment. Therefore, it's crucial to ensure that all construction processes and product selections are done with safety in mind to prevent long-term issues.

1. **Preventing Cracks in New Walls**
When building or modifying walls, it's important to ensure a strong bond between new and existing structures. Industry experts recommend using wire mesh during plastering to reduce cracking. It's also advised to wait at least 7 days before proceeding with further construction. This allows the new wall to settle and minimizes the risk of future delamination or movement.
*Tip:* Poorly reinforced walls can lead to cracks, which may compromise waterproofing and cause tiles to fall off over time.
2. **Reinforcing Key Waterproof Areas**
The floor and shower walls are the most vulnerable spots in terms of waterproofing. If the shower area isn't fully enclosed, the waterproofing should extend up to 1.8 meters on the walls. Pay special attention to corners, pipe outlets, and drains—these are common weak points. Applying waterproof paint with non-woven brushes in these areas can help prevent cracks from spreading.
*Tip:* Avoid sharp angles in corners; use rounded edges instead to prevent thinning of the waterproof layer and reduce the risk of leaks.
3. **Water Pipeline Renovation**
There are two main methods for updating plumbing: full renovation or partial repair. However, partial repairs often lead to more problems. When connecting old and new PPR pipes, it's best to use joints rather than welding, as different manufacturers may have varying melting points, leading to potential leaks over time.
*Tip:* Avoid placing joints in hidden areas like walls or floors. Keep them accessible for easy inspection and maintenance.
4. **Electrical Safety**
The bathroom is a high-power usage area, so it's recommended to have a dedicated circuit. Mixing circuits can cause overloads, especially with high-wattage appliances like electric water heaters. A properly sized leakage protector is essential to prevent shocks and short circuits.
*Tip:* Install switches outside the bathroom, and ensure all wiring is sealed, waterproof, and insulated. If there’s a socket, keep it away from water sources and use a protective cover.
**Product Selection**
5. **Choosing Waterproof and Non-Slip Tiles**
High-quality, dense tiles are ideal for bathrooms due to their superior waterproof properties. They help prevent mold and mildew. For flooring, prioritize anti-slip features—test tiles by stepping on them, and consider those with textured surfaces for better grip.
*Tip:* Ensure tile strength is sufficient to withstand wear and tear, as weak tiles can crack or fall off, posing a safety risk.
6. **Selecting a Leak-Proof Smart Toilet Seat**
Smart toilets come with multiple leak-proof features, but it's important to check for certifications and flame-resistant materials. Quality is key, as poor construction can lead to electrical hazards.
*Tip:* Even with dry-wet separation, proper ventilation is essential to avoid moisture buildup and potential short circuits.
7. **Choosing High-Quality Tempered Glass**
Tempered glass used in showers is tested for impact resistance, but it can still break unexpectedly. Opt for tempered glass with added adhesive or silk for extra safety.
*Tip:* For elderly family members, consider adding grab bars or seating options in the shower to improve safety. Also, ensure good ventilation to avoid "bathroom syndrome" caused by high humidity.
