Can anyone give me a cost estimate to add a bathroom and 250-300 sq ft addition...I'm looking for a general cost to add a bathroom and about 250-300 sq ft.The bathroom would be a 3 piece - toilet, stand up shower (tiled w/glass doors) and double vanity. It will be on a wall that has a bathroom/plumbing on the other side of the wall already. Also, the general cost to extend a bedroom out into the backyard of the house about 250-300 sq ft (I don't think any electrical would need to be added, basically just shifting a wall back). The house has vinyl siding on the back. We are in the midwest, in Missouri. We would be doing most of the labor ourselves, besides construction/foundation and outside walls. In other words, we'd be purchasing/installing the toilet, vanity/sink, tile (but not shower) in the bathroom.Also, while we're at it, how much money could we save drywalling/mudding/taping everything ourselves?These are hypothetical questions, I'm just looking for very general cost estimates. Nothing super fancy, but not absolute lowest grade materials either.Thanks!January 22 2013 - Springfield00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
