My downstairs ceiling is already removed, and wondering before I reinstall if it is providence and I should try to use the opportunity to add a shower to the upstairs bathroom. The shower would need to go where the existing toilet is, and the toilet to the sink locale. The sink would move over a bit. Total bathroom is 4x8 and toilet would move about 4 feet, sink about 2 1/2.

If this is possible, would it be a job a (handy)woman could do herself ? ~Thanks!
