Would a toilet be considered a fixture?

Yes, a toilet would absolutely be considered a fixture, and it is in fact one of the textbook examples used to explain the concept. A fixture is an item once movable that has been affixed to real property permanently, and a toilet meets every criterion. Physically, a toilet is bolted to the bathroom floor with closet bolts, sealed to the drain flange with a wax ring, connected to the home's potable water supply through a shut-off valve and fill line, and plumbed into the sewer or septic drainage system. Removing it requires tools, shutting off water, and disconnecting it from utilities, and its installation demonstrates unmistakable intention of permanence. Legally, toilets are classified as plumbing fixtures, and in real estate transactions they transfer automatically to the buyer as part of the real property; sellers cannot lawfully remove a toilet and take it with them unless the purchase contract explicitly provides otherwise, which is virtually unheard of. In the plumbing profession, "fixture" is a standard technical category: toilets are listed alongside lavatories, bathtubs, showers, and bidets as plumbing fixtures, and building codes measure their demand on piping in "fixture units" to size water supply and drain lines. Codes also mandate minimum numbers of toilet fixtures per dwelling and occupancy type. Hardware retailers shelve toilets in the plumbing fixtures department. So whether the question arises in casual usage, a property sale, a renovation, or plumbing code compliance, the classification is unambiguous: a toilet is a fixture.
