How many fixtures can you attach to 1 bathroom drain?

Typically, one bathroom drain can accommodate multiple fixtures, such as a sink, shower, and toilet, depending on the Plumbing design and local codes. Generally, a common bathroom drain can handle two to three fixtures without issues. However, it's essential to ensure proper venting and drainage capacity to avoid clogs and backups. Always consult local plumbing codes or a professional plumber for specific requirements.
