Shower drain connection to toilet sewer line
[F][F] Hi... just found this site with a Google search so am a newby here! We live in a raised ranch and have a half bath (toilet and vanity) in a lower floor bathroom. Bathroom floor is about 4 ft. below ground surface. Fixtures and drains were installed when house was built. We would like to add a shower in the bathroom... there's plenty of room where a hot water heater used to sit, and the cold in, hot out lines were capped when the heater was moved to another location so water flow should not be a concern. The question is shower drain installation: The shower base would be 6-8 ft. from the toilet. Can the shower drain be connected to the toilet drain? A cut through the existing floor would be needed, but I'm not sure how deep the toilet sewer is buried under the basement floor for connection to the main sewer outflow. Avoiding a possible sewage backup to the shower drain is also a concern, as is whether additional venting will be needed. Most appreciate your suggestions... LesC37
