Some smart toilets can still flush during a power outage, but others cannot. It depends on the model’s flushing mechanism and whether it has a manual flush option or backup power. Electronic comforts such as a heated seat, bidet spray, dryer, automatic lid, and night-light generally stop working until electricity returns.
A power outage does not necessarily shut off your water supply. If water pressure remains available, a toilet with a working manual or battery-backed flush may still clear the bowl. However, water availability alone does not guarantee that an electronically controlled toilet will flush.
Look for the outage instructions in your toilet’s manual before you need them. Depending on the model, you may have one of these options:
If you use a well pump or your building relies on an electric pump, an outage may also interrupt the water supply. A backup flush feature cannot make up for unavailable water unless the toilet’s design specifically provides for it.
For a bathroom that needs to stay usable during outages, our team recommends prioritizing a clearly described manual or backup flush. Find out whether batteries are included, how they are accessed, and whether backup operation supports flushing only or other functions as well.
Consider your household’s water supply, too. If outages regularly affect your water pressure, plan for both problems rather than focusing only on the toilet’s electrical connection. Keep the operating instructions somewhere accessible, and make sure everyone who may need the toilet knows how to use its emergency controls.

A smart toilet’s electronic features need a suitable power source. If there is no outlet nearby, have a qualified electrician install one that meets the toilet manufacturer’s requirements and local electrical codes.
