Double-shower vs. Tub in a rental?

[Tatiana K.]

Hi BP, need a spot of advice for a bathroom reno in a duplex. Quick stats on the unit - 1920's structure, 1/1, approx 900 sf, projected rent $1650. 

The current bathroom layout isn't up to code so we're going to have to widen the room and shuffle the fixtures regardless, which got us on the tub vs shower question. It's the only bathroom in the unit, but is getting rid of the tub a bad idea? All the home reno forums say yes, but this isn't an SFR, it's a rental unit.

My opinion is we should keep the tub to appeal to the broadest possible audience. Husband argues that having the dual shower could be the wow factor that really sells the place to a prospective tenant. Either way we'll make it home-quality finish. Any thoughts?
