Floors in toilet rooms must be constructed of what type of materials?

Floors in toilet rooms must be constructed of non-absorbent materials to ensure hygiene and facilitate cleaning. Non-absorbent materials do not retain moisture, which minimizes the risk of mold and bacterial growth, contributing to a healthier environment. These materials, such as vinyl, tile, or certain types of sealed concrete, are designed to withstand constant exposure to water and waste, making them ideal for areas that experience high humidity and liquid spills.

Using absorbent materials could lead to significant maintenance issues and health risks, as they can absorb wastewater and odors over time. Wood materials, while sturdy, may deteriorate when exposed to moisture, leading to rot and structural damage. Metal materials could potentially be used in some designs but are less common due to issues related to corrosion and temperature fluctuations in restroom environments. Non-absorbent options are the most practical and safe choice for toilet room floors.
