Should You Keep Your Tub?

After our remodel is finished, our home will have 2½ bathrooms. My wife and I decided to forgo a tub in the master bathroom in favor of a large walk-in shower because we aren’t bathers.

But for the second bathroom, which will primarily be used by our guests, we can’t agree on whether to include a tub. I’m on team “no tub” and would prefer a nice tiled walk-in shower. My wife, however, is concerned about future resale value and thinks we should include one.
So I decided to ask around to find out what the current thinking is on keeping the bathtub or getting rid of it.
