Hot wash water would clean the bowl and the hot water in the bowl would warm the seat. The cold first rinse water would be tempered by the heat from the hot wash so that could be the water for the bidet with enough force from the pump to be a power douche or enema if required. The vibration from the spin would shake the tushie dry. The two recesses on either side of the seat give a leverage point for the elbows when bracing for pushing. For those who wish to sit so that they can watch the performance, there are the knobs at the top of each recess to provide leverage in the other direction. I wonder if you have to stand on the seat cover to reach the dispenser drawer?
