What precaution is recommended for safety in the bathroom?

Installing night lights in the bathroom is a recommended precaution for safety because they provide adequate illumination during the night or in low-light situations. Good lighting helps to prevent slips and falls, which are common hazards in bathrooms due to wet surfaces and the potential for tripping over objects. By ensuring that pathways, especially around the tub, toilet, and sink are well lit, individuals are less likely to experience accidents, making the bathroom a safer environment.

Other options, while they may have some relevance, do not address the critical aspect of visibility and safety in the bathroom. Bright colored mats, although they can provide some visual cues, do not enhance safety effectively without the necessary illumination. Leaving medications accessible poses a risk, especially to children or those who may be confused, as it can lead to accidental poisoning. Filling bathtubs completely can create another safety hazard, such as the risk of drowning if someone slips or loses balance in the water.
