My biggest disappointment when I moved to the US many years ago was my (standardised) bathtub. When living in Switzerland, I used to spend about half an hour every evening in my old, huge bathtub, reading a book and sipping my scotch. Then, my ~one-year old son would join me and we'd spend another half hour playing together. It was like being in a swimming pool. Absolutely great! Different strokes for different folks...
