Locating New Bathrooms Next to Existing Ones

The sad truth is that a new simple bathroom will most likely cost a MINIMUM of $8,000, and could cost many times that. The additional cost of plumbing the bathroom, where you actually would like to have it, may add 10% to the total cost of the project. But having it in the right place would seem to me to be well worth that

This bit of shortsighted wisdom leads to some funny basement bathrooms. I am thinking of the ones with the toilet on a pedestal, a real throne.
