Turning a small bedroom into a bathroom
We are considering purchasing a house that has 3 bedrooms and one very small bathroom. If we turned one of the bathrooms into a master bathroom (and would have room left over for storage) it could work for us. Has anyone turned a bedroom into a bathroom? I realize costs can vary greatly, especially as we choose fixtures and the like. But fixtures and finishing costs aside, is it a huge and costly undertaking to turn a bedroom into a bathroom?
The bedroom we are considering transforming currently does not share a wall with the existing bathroom. We'd have to run the plumbing under the floor, I suppose? If we changed our ideas around and built the bathroom in a bedroom that DOES currently share a wall with the existing bedroom, would that be easier and less costly?
Thanks for your thoughts!
