When you become a homeowner or rent from a bad landlord, you eventually get a little familiar with the workings of a toilet.  I know I’ve done some repairs.

The reason is sometimes there just isn’t time to wait for a plumber.  You need to try and fix something immediately and so you bust out the toolbox and figure it out.  Sometimes it gets fixed and other times it doesn’t.

Whether you’re renovating a bathroom, building a new one or simply installing a new toilet, it can be helpful to check out a detailed diagram that shows you all the parts of a toilet.  Below is our extensive and detailed diagram setting out and labeling the tank, toilet bowl and plumbing followed by a description of all the parts.
