tub in shower-kids can splash and "swim" as much as they want! This is a brilliant idea for adults too. Whenever I take a bubble bath I end up wanting to shower off at the end. This way you can just step out of the tub and shower off. I love, love, love!!! This qualifies more as a dream than a possibility but hey... :D
Millennials have been criticised for being selfish or "me me me", but they don't see it that way, they have just taken the tools given to them and ran with it, to make it happen and push the boundaries. They decide what they are and self define themselves. Perhaps it is a generational thing where everyone looks to the generation below as more self absorbed?
