I don't know about vinyl, per se, but floors and walls expand and
contract. Leaving a small gap is to keep rigid stuff from buckling or
cracking. You grout all the tile spaces, but use caulk at corners
(betw. walls/floor/ceiling) for the same reason. Caulk flexes, so it
won't crack or buckle. Caulk also helps contain spills and leaks. Not
long after we had liv/din rms tiled and new kitchen installed, we had a
major flood from broken washer hose. The caulking helped keep the water
from spreading into wall spaces and other rooms. Not a major issue if
you clean up the rest, of course, but you never know. When our water
heater began leaking (it is under corner cupboard in kitchen), it didn't
become evident until the water leaked out from under dishwasher, about
8' away...the floor is terazzo, but apparently has ever-so-slightly
uneven surface so the water flowed under the row of cabinets from hwh.
