Single Bathroom dimensions are typically standard in housing. Unless you're not in the typical single-family home design, which is basically the GI Bill '40s Military Base housing DNA. And because of this - billions of tubs could be manufactured at standard rates and allow the US to expand after WWII with a standard of hygiene as a part of our culture as we 1st-worlded. So now, large tubs are a matter of being a spender and you paying top dollar for anything non-standard in the US. WHen I was a kid, we had a house in tahoe and it had a two huge tubs - an internal hot-tub that was a giant 6' diameter half wine-stave-style tub, and a large 5'x5' shower/tub that had two shower heads. It was built by an awesome hippy guy in Tahoe. Ever since then, I love nice tubs.
