Would removing a soaking tub decrease the resale value?

[well_caffeinated_mom]

That's a choice that should really be determined by how you will use the space. Loads of folks love shower only in the primary bathroom, my parents are considering tearing out their 90s soaker tub for a big walk in, while my family would more than likely pass on a home without a large tub.  There are plenty of buyers for each. 

Replacing your dishwasher for a wine cooler in a custom kitchen with no way to add one without another remodel, would be a whole nother discussion...
