too many bathrooms?

I've been house shopping in Queens and Brooklyn. Unfortunately, I look at a lot of houses that were flipped (someone buying it for 200-250k, updating it with the crappiest fixtures ever then selling it for twice that amount). A constant theme, I see is adding unnecessary bathrooms (i.e. a full bathroom next to a kitchen). I assume they are attempting to increase the value of the home BUT they aren't practical. Sorry for rambling but my question is are there any downsides to the extra bathrooms? Will this effect my water pressure or water bill? Besides wasted space... are there any disadvantages to this? I will never have a spontaneous desire to take a bubble bath break from cooking dinner. Should I be concerned?
