An electrically heated bathtub, with an inside wall, an outside wall and a bottom floor, the inside wall having an outer surface and an inner surface, the outside wall having an outer surface and an inner surface and the bottom floor having an outside bottom surface and an inside bottom surface. A heating element is attached to the outer surface of the inside wall and conductively heats the inner surface of the inside wall, which in turn heats any water that might be in the bathtub without the heating element being exposed or protruding through any surfaces. The heating element is also attached to the outer bottom surface of the bottom floor and conductively heats the inner bottom surface of the bottom floor, with the heating element spread evenly throughout the outer bottom surface of the bottom floor.
