ELI5: Why is everything bigger in America except the bathtubs?

As an American visiting the UK, one notices everything is just a bit--sometimes quite a bit--smaller. Coke cans, roads, cars, houses, all hit with a shrink ray. Makes sense, since there's less room to work with over here.

That is, until you get to the bathroom part of the house.

There you may luxuriate in the bathtub, which normally is long enough for average Britishers to submerge their entire bodies in water ***without having to scrunch their legs up like every American has to do!***

On noticing this, I feel I've been cheated. It's not like we don't have the space for these huge tubs in our houses. So ELI5: why did North American builders make this pact with the devil to only install small tubs in houses? Why, oh why?

Most American adults don't take daily baths, so the bathtub is mostly there for kids and so that the realtors and assessors can check that box saying they have a tub to raise the value of the home.  Bigger tub = more floorspace taken up = less room for other activities.
