The seat warmer has an energy save feature or can be shut off completely.

Before you go and judge why don’t you look where this toilet originated, in Japan, where there is no central heating. Before you go judging why don’t you spend a winter in a near-frozen home, b/c that’s the way you spend your winters in Japan. One luxury, like a heated seat, helps to offset that it is really really cold during the day and at night in a home in Japan. Point your fingers elsewhere, esp. Americans that sleep with the temperature in the high 50s and 60s in their homes. Ugh.
