I hate FS tubs and they very often are not in a space that can handle one . I like nmy guest rooms bathroom to have a tub/shower to cover all likes . I prefer a nice alcove soaker tub to a FS one any day. I love my tub but I will never have FS one they are a PITA to get in and out of and require weird shower curtain setups too.

As far as resale, who knows? Depends on the particular buyer and their specific needs.

If most of your guests would prefer a shower and you plan on being there for many years, then do what works best for you, and not for some mythical future buyer.

exactly what chispa said. I wished I had removed our tub 20 yrs ago when we redid the bathroom. hate that tub.

as long as your have a tub in the master bath, it will be fine. go for the shower

If most of the occupants will shower, and there is a tub "somewhere" - get the shower.

Showering is a tub is so sub optimal - you are dealing with climbing over the tub, a sloped bottom usually front to back, and then sloping sides to a small standing area. Shower curtains tend to always stick to me no matter how I try to avoid. And IMO sliding glass enclosures usually look bad on a tub / collect crud because..... ALMOST EVERYONE IS USING IT AS A DARN SHOWER ANYWAY!

You'll find this board is fairly well split down the middle on this topic. About half the regular posters will say go with a big, luxurious shower ... and the other half will say they use the tub regularly. The real question is, what are YOUR habits?

FYI: The drain locations of Kohler Bellwether shower bases are designed so these shower bases can easily replace bathtubs.

@Mrs Pete the difference here is that this is a guest room. Guests do not regularly take baths when they are guests (I have never had a guest take a bath). OP has a tub in their bathroom so in this case I would absolutely replace with a shower. The big argument for having tubs in non-primary bathrooms is for kids. It's really not a big deal for a kid to take a bath in Mom and Dad's bathroom if there's no other option. My kid has a bathtub and still takes a bath in ours sometimes.

Shower for sure.

I'm in the middle of a new build right now, and in our current home our giant corner tub does nothing but collect dust... We hate it. So we knew immediately that we would not have a tub in the master bathroom of the new house. In the space where the tub would have gone, I am having a long makeup vanity and a place to pull up a stool for makeup, hair, etc. We'll have a walk-in shower which is plenty for us. That being said, we are building on a crawl space and our builder said he would have that area plumbed beneath the floor, in case we or any future owner might want to install a tub there.

We do have 2 other bathrooms in the house that will have tubs. Since this is our 'retirement' house, we really didn't get too concerned with resale when it came to the master bathroom tub issue.

I think as long as you have at least one tub somewhere in the house you should be fine.

Who will be staying in the guest room? If it may be older parents, then definitely go with an easy entry shower. One tub in a home is a must for resale value, but because the main users of tubs are the homeowners or their kids (who can use the primary bathroom tub for the few years before they start showering), one tub is enough. We have tub/shower combos in our two hall baths, and in 40 yrs, I don’t think we’ve ever had guests - except young grandchildren - who have used the tubs!
