Bathrooms with more than one toilet or a urinal are required to have what?

Bathrooms with more than one toilet or a urinal are required to have a floor drain to ensure proper drainage and sanitation. The inclusion of a floor drain is crucial in situations where multiple fixtures are present, as it helps manage any overflow, spills, or potential flooding that could occur. This is especially important in commercial settings or high-traffic bathrooms where the chances of water accumulation are greater.

The presence of a floor drain also aids in the overall maintenance of hygiene within the bathroom. It facilitates quick drainage of water, which reduces slip hazards and helps to maintain a clean environment. Additionally, floor drains help to prevent standing water, which can lead to mold growth and unpleasant odors.

Other options may not specifically address the critical requirement of drainage in multi-fixture restrooms. While sinks, ventilation systems, and additional toilets have their importance, they do not fulfill the primary need to manage drainage effectively in such facilities. Thus, having a floor drain is essential for compliance with the Massachusetts Plumbing Code in these scenarios.
