I'm in & out, probably 2 minutes but I will time that just out of interest. In our household the tub is the higher cost and a timer won't help, only the amount of time per week. Over the holidays we used it 5x per week. I keep joking that we should add a counter. Worse is that it's all heated by gas coming from Russia (North Stream 1) and who knows if the UA conflict mean it gets cuts off.
