Yes—by rinsing instead of wiping, a bidet reduces your toilet-paper habit and the resources required for every roll. Each use requires an average of 0.125 gallons of water, compared with the 37 gallons needed to produce a single roll of toilet paper. That gap shrinks your household’s water footprint and keeps extra paper out of the trash.

Swapping in a bidet seat is a quick job that a professional plumber can complete in 30 minutes. A full bidet toilet or standalone unit, however, takes two to three hours. A licensed plumber can handle the plumbing tweaks, venting, and leak checks in one visit, protecting both your floors and your warranty.

For most households, yes, installing a bidet is a worthwhile investment. A bidet helps trim your toilet paper bill, leaves you cleaner, and lightens your environmental footprint. It also gives the bathroom a modern, spa-like feel that many buyers notice when it’s time to sell. Those combined perks make the upfront cost a smart long-term play.

Most electric bidet models use a built-in heater that warms the spray on demand. Non-electric versions tap into the home’s hot-water line—usually the one feeding water to the sink—so you still get a warm rinse, though you’ll need the services of a professional plumber to run that line behind the toilet.
