renovated bathroom

If you only have one bathroom, I think the chances are that it will limit the top price you could obtain on resale if you elect to install only a walk-in shower (aesthetically, I love the seamless look of a walk in shower).

As regards a tub, however, if you can afford it, I would avoid a drop-in tub, which I think always looks cheap (and particularly jetted whirlpool tubs which look really grotty over time), and opt for the more expensive proposition of a fully integrated wall forming a tub (note the olive green tiled bathroom/sauna pic in the old streeteasy listing below to illustrate). The only thing you have to take into account when building a integrated tub wall like this is to have the proper angle on one side so that it is comfortable to lay down in - if all the walls are 90 degrees, it's not ergonomic...

We just placed an offer on an apartment however before this we saw an apartment we really liked that had a shower and no tub. We chose to pass on the apartment because of this. I am sure others felt the same way. So, I think it is a pretty important issue and would be a bad decision for future sale potential.

To each their own, but to me that integrated tub is horrible. Uncomfortable positioning, impossible to clean, not particularly comfortable on your bare a$$, and it looks pretty difficult to get in or out of. And, maybe this works on the first floor, but I would not want to trust someone's tiling skills to create a permanently leak proof vessel holding 90 gallons of water of above my head.

keep the tub. no young couple will consider buying your place if there's no tub.

if its the only bathroom, your apartment will have less appeal to anybody with a toddler/young kid as they need to use a bathtub typically.

Yup--as people have mentioned, keep the tub. No question.

And stepping into a flimsy acrylic tub is skeevy. Enameled cast iron the only way to go:
