I am currently doing this to our guest bathroom. the way I look at is that you live in the house and should be designed to make you happy. Mine has a crappy little tub that is only used by guest to stand in when they shower, typically my mom and mother in law in their 70s. I am ripping it all out and putting in a travertine shower with a glass wall and walk in door with hand rails to make it easy on the gals. No more stepping over a tub and fumbling with a cheesy shower curtain. I am putting in a fold up teak shower seat and a hand wand shower head for them as well but could easily be used by adult in the future to wash an infant.

I think if you do a well thought out layout with quality materials the majority of people will like that more than a less than interesting bathroom with a little tub in it. You could also add a nice hot tub outside in the future. The vast majority of people in the USA prefer showers and many NEVER take baths. Folks told me not to take my 5th bedroom and connect to my wife's master closet to make her the ultimate chick room because 5 bedrooms are hard to find in my area. Let me tell you, the good will that gigantic closet with built-ins generates from my wife to me every morning she goes in there is priceless.
