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?

Alright im going crazy spinning in circles trying to find the best flooring for my application. We are renovating our basement full bathroom. The bathroom also has our mechanical room attached to it in a closet. And there is a floor drain somewhat in the center of the room. So there is a slight slope towards the drain, something around 1/8" per 4 feet. Any recommendations for what flooring will work best for the application? I'm leaning towards vinyl plank due to its waterproof characteristics. I dont like tiles I'm open to any flooring available at a box store and would like it to be $3 psf or less (Canadian). And secondly is there a floor drain cover type of deal to put on your vinyl (or any) flooring so it drains down into the floor drain on the concrete? Thanks, TTiffin
