New toilet installation is not much different than removing and reinstalling an old toilet. The only differences are that the toilet back and toilet seat assembly which come with instructions when you buy a toilet. In some cases, toilets bowls and backs are a single piece which obviously does not require back assembly.
With this new toilet, the only different installation procedures were to add the spacers underneath the toilet seat and to assemble it to the holes in the toilet.
Now that we have installed the toilet seat, we can check out the rest of the procedure at https://plumber.fullstackwebstudio.com/blogitem/toiler-removal-and-reinstall.
