If your trusty toilet has developed cracks or leaks, uses far too much water per flush, or is simply a shade of baby blue not seen in 20 years, it may be time to replace it. You might consider this a good time to put in a call to the plumber, but it can be all in a day's work for a reasonably handy do-it-yourselfer. It's not for the weak, since toilets are heavy and unwieldy, but if you have a strong back (or a sturdy assistant) you can save yourself the cost of a house call by installing it yourself.
Here, we asked This Old House plumbing and heating expert Richard Trethewey to show how to install a new toilet. The time required varies, but give yourself half a day if you’ve got a lot of experience with plumbing jobs, and a full day if you’re a novice.
