I hate showers over baths, mainly as I know a number of older people who only have sponge baths as they can not get in the bath shower. Unless you are aiming towards another market when you start renting it out this wouldn't be an issue

In a 3 bedroom I don't think 2 toilets would be a big factor either way, if the only toilet was in the bathroom it would put me off though.

Well that probably wasn't all that helpful!
