If you are planning on finishing the basement, then--yes--it makes sense to add a bath. It's a real pain to have to go upstairs to get to a bathroom.
It also, obviously, depends on the quality of the job.
And without rough-ins, your price will vary, depending on where you locate it.
Hope that helps.
We do not have the rough in for the bathroom. But I have been trying to figure out how much adding a full bath would do to our home value. We are thinking about doing the basement in phases. Do a family room with bathroom.
I would like it very much to get in contact with your general contractor. So my family can get an estimate on what it is going to cost us. I will contact you to get the information.
Thank you both
That will depend on whether your basement already has a rough-in for a full bath or will need special plumbing. In either case the cost should be less than $10k and you will get that full return back on your investment in your homes value.
