I am turning my workshop into living quarters, the area were I want the bathroom is about 35ft behind my 1997 valley manufactured home, the master bath is closest to the shop, can I just tap into the toilet/shower drain in the master bath? Or what would be the best and most cost effective but right way to do this job.

You wish to run back from your workshop into your mobile home to connect to the master bath group? Are you on a septic system and why not connect the workshop to the sewer line? Let me know. Tom

Yes I am on a septic, the septic is about 110ft away from the shop, I was told I can just tap into the existing drain/septic line from the house so I don't have to go the total 110ft.

I was told I can just tap into the existing drain/septic line from the house so I don't have to go the total 110ft. That would be the way I'd do it. Let me put up a diagram of a typical installation, Good luck, Tom
