We're getting ready to finalize the plans on a detached workshop this spring and I'm really torn with whether or not to put a bathroom in the shop. I've gotten multiple quotes and I'm looking at adding an additional $12,000 just for the rough in. This includes running water from the house and attaching to the existing septic system. I figure it'll easily add $15,000 by the time you figure a water heater, toilet, sink, and shower.
I've got a few questions before making the decision.
1. Does the price sound appropriate? We'd be looking at running water, sewer, and gas lines approximately 100' to reach the shop.
2. Has anyone ever heard of a small point of use septic system? My thought is this may be a cheaper and better alternative than tapping into the existing system.
3. Assuming the $15,000 is the total cost for a functioning bathroom, is having one in a shop worth this amount?
4. Can a water and gas line occupy the same trench? None of the contractors I've spoken with have been able to answer this question.
This bathroom would also service the pool so we'll be getting double duty out of it plus the gas line for the water heater would allow me to heat the shop with gas versus propane or electric. Please assume the existing septic system can handle the additional bathroom.
I've got tons of other questions but these are the ones holding me back from finalizing the building plans.
Thanks,
Wes
