$40 to $120, it just depends on where you live and who does it. It is very simple to do if you have any mechanical skills at all and the strength to do it. The only issue is if it has been leaking for any time at all, the floor may have to be repaired due to rot. That could add $500 real easy depending on how bad and who does it. The wax ring itself is only about $5.
