Final answer:
Bathrooms should have wall-mounted lighting in addition to overhead lighting to ensure even, shadow-free illumination for tasks like shaving or makeup application. Safety is also a concern with bathroom electrical devices near water.
Step-by-step explanation:
The most suitable lighting in a bathroom is crucial for practicality and aesthetics. Having only overhead lighting can create harsh shadows and uneven illumination, which is especially problematic when performing tasks like shaving or applying makeup. To ensure even and shadow-free illumination, it is beneficial to install wall-mounted lighting above or on either side of the mirror. This lighting design can help in creating a more flattering and effective light, reducing shadows that can impede one's ability to see clearly while using the mirror. Additionally, from a safety standpoint, certain electrical devices used in bathrooms come with safety warnings against use near full bathtubs or basins due to the risk of electrical shock, which could be dangerous or even fatal.
