Frequently Asked Questions:

Do you need electricity for a bidet?

An electric bidet can work by electricity. Bidet’s function can be powered entirely without electricity – even in an electrically-powered bidet. That is, the stream itself can be powered solely by the home water pressure. It provides a pressurized stream of water to wash your private area.

How long does a tankless toilet last?

The basic rule of a toilet can last up to 50 years, but replacement is more than likely necessary after 25 thanks to damage, regular wear and tear, and low water pressure.

How long does a toilet wax seal last?

 The wax ring keeps water from leaking as it passes from the bathroom to the drain pipe. It seals against foul sewer gas odors. A wax seal will often last the life of the toilet, 20 or 30 years, without needing to be changed.
