Would the above set-up put you off a property? If the only shower was in the main shared bathroom (albeit a luxurious walk-in shower of your dreams), and the only bath was in the en-suite off the master bedroom.
I guess this is the reverse of what people normally do? The reason I'm thinking of it is that the en-suite doesn't have enough head height for a shower (in the eaves), while the main bathroom doesn't really have enough space for a bath + sep shower. And ideally I really would love a walk-in shower, not a shower over a bath.
