I have been asked to replace a toilet in a friends house, went to see the job today and the toilet is bedded on a cement base. Now i think the only option is to smash the toilet out, but i was thinking should i rebed it on a cement base or what i want to do is remove the cement base, screw it to the floor and seal it. Is there a better option for me because removing the base i would imagine could take a while. Any opinion advice greatly appreciated.
