When I did this same job in a high rise condo and the work was performed on the 47th floor of a 60 story building I had to charge the condo owner $71,000+ as I had to work in the apartment below and had to cut into the 8" cast Iron stack and re vent piping

When I did this job in a one family home and the bathroom was located on the main floor where the piping was all exposed and the cast iron was only 4" diameter I was able to do this job for $6,200

ANYTHING is possible as we did put a toilet on the space shuttle.

Just a matter of location and what one is willing to spend

thank you for the reply. now this is two level house. the toilet that i want to shift over 3 square feet is on the second level...top floor. i was hoping for a low cost job because if this does require a hefty price tag, i will not bother with this.

Filing fees, Hiring a licensed and INSURED plumbing contractor, plaster, tile work water lines re venting min size toilet waste is 3" and as for as I know there is no such thing as low cost in plumbing when it comes to locating a toilet as the venting and larger size waste lines.

Depending on the area of the country your in what the labor rate would be as each area has a different cost of living
