Installing vinyl plank flooring next to tiled wall

My project involves installing LifeProof interlocking vinyl plank flooring over the current cement tile in my 12x12 kitchen, which is mostly cluttered with cabinetry but has a length of old-style glazed tile wall floor to ceiling. The instructions demand a 1/4 inch gap all around. With the cabinets this is okay, since the overhang will mostly hide the gap. But what to do about the tile wall side? It'd be best to run it right along the tiles and allow expansion on the cabinet side, but I doubt that would prevent buckling even over a relatively small distance of 9-10 feet. They say "cover with a molding of your choice" but there is none. Adding a molding would look plain ugly, since the bottom row of tile are designed to be a molding of sorts. Even if I did add a molding, it says to "attach to wall, not to floor". How should one do that to glazed tile? Some glue adhesive? If I wished to really suffer, I'd cut a gap along the bottom of the wall tile -- however, I'm worried that this 90 year old tile would start popping off the wall if I disturbed it with a vibrating cutting tool (which has happened along the upper tiers of tile in other spots). At the same time, there's no room for a gap where the planking meetings the marble threshold pieces at either door. It has to abut.

Bottom line: do I really have to maintain that 1/4 inch gap all the way around in a relatively small area such as this? Total floor area cannot exceed 90 sq ft. Can one length of air gap suffice for this kind of flooring? Or am I asking for trouble?

 

So the manufacture recommends that you maintain a 1/4 gap around the floor and you want to know if you have to.

Of course you dont have to do anything the manufacture recommends but then you cant come back complaining when the floor is buckled.

You have an unusual situation where you cant install a traditional molding due to the tile, Is there some type of flat transition piece that could be installed that would cover the gap?

For this one you are going to have to be creative!

 

Yes, thank you. I asked because the manufacturer may cover their own liability by stating a flat rule for how to handle product without having irate customers complaining afterward. My question was whether there is leeway in the "rule" depending on the area of the material. For example, they do not recommend greater than 30x30 coverage. They don't say why, but I reckon its because anything larger than that would mean little room for expansion from the middle, thus causing buckling and warping. And it causes me to wonder if the opposite is true: that the smaller the area, the less expansion and therefore the smaller the gap; or in my case, no gap on one side. Rather than experiment on my own, I prefer to canvass for opinions or experiences regarding vinyl plank usage.
