Sometimes a shower just doesn't cut it. Your body is sore, you're tired and all you want is a nice, hot bath. But forget about the baths of yesteryear, these days we have Jacuzzi-like tubs with intelligent temperature control, smartphone automation, massaging jets and more. There are even self-cleaning bathtubs for those who can't do it themselves. Technology has found its way into our bathrooms and it's here to stay.
