These aren't silly questions if you are not in the industry. As I said I am keep everything in the same location and wanted to know what the average time it would take. The work would be less than rearranging the whole bathroom. I needed a estimate of time it would take to unplug and then attached the new bath toilet and sink, tiling would be done by someone else.
Example you ask a cabby how long it would take to go from A to B, cabby says 1 hour. Of course it is not going to be an hour it could be a bit more or a be less. I wanted to know average time it would take.
If you don't know, or going to be unhelpful why post?
