Renovating old houses often involves prioritizing the kitchen and bathroom, but many have the intention to renovate the bathroom but lack the preparedness. Concerns about the complexity and time-consuming nature of bathroom renovations often deter people from proceeding. However, with constant exposure to water and damp air, the bathroom's condition is indeed concerning. Homeowners looking to renovate their bathrooms should remember to prepare in advance, act proactively, and not skimp on these areas to ensure a more worry-free renovation.

Waterproofing in bathrooms is crucial; the wet area walls should be sealed at least 1800mm high, and corners, pipes, and other areas must be carefully sealed as well. For bathroom tiles, opt for relatively economical options that ensure waterproofing. Non-shower areas can be directly painted with waterproof paint, saving space and reducing costs.

Safety should be a top priority; when selecting tiles, prioritize slip resistance. Since the human body comes into direct contact with the ground, pay attention to the quality of the material. Opt for matte tiles or patterned tiles with excellent slip resistance.

The bathroom is a place where multiple water and electricity converge. It is essential to choose quality pipes and wires during the early stages of renovation, ensuring proper wiring to prevent leaks and electrical hazards caused by design or material issues. If you plan to install smart toilet lids or an entire bathroom suite, be sure to pre-allocate outlets during renovation to avoid the hassle of re-wiring later.

The bathroom has been divided into wet and dry zones, first and foremost to isolate moisture. Moisture can lead to various issues such as mold, unpleasant odors, and breeding of bacteria. Moreover, with the wet and dry separation, the bathroom can be better functionally zoned, making it very convenient to use. The quality of glass used in the shower room is crucial for bathroom safety; good tempered glass is hard to break and, if it does, it doesn't hurt. Therefore, it's essential to choose a brand with a good reputation.

Basins typically use floor drain designs, while more upscale spaces can opt for wall-mounted drainage. It's crucial to include S-bends to prevent backflow odors. For smaller spaces or on a budget, you can forgo a full bathroom cabinet and use an open iron stand to save space. Mirror cabinets and space-saving recessed cabinets are more suitable for compact areas, fulfilling the bathroom storage needs.
