    I have a concrete floor basement bathroom and in preparing for layout I am of the understanding that it is a good idea to leave an approximate quarter inch Gap around perimeter of the walls my question is how do I fill in that quarter inch Gap once everything is done can I fill that in with some type of mortar or grout I don't know that it's a perfectly Square room either so I'd like to make the room look good but I don't know how much putting quarter round around the room is going to look. Most of the time when I take on a new project the details seem to be what make the difference so I'm thinking this project through and it seems as if that might be one of the details that would make a project look good or bad

    I just finished priming and painting the walls and I will be leaving them painted. I'm going to take a photo and send it along with this

    Are you installing tile? How about matching tile base.

    The gap recommended is for expansion, it's a small area so it won't expand much. I would put tile 1/8" away and color match caulk grout. Or cover with base.

    1/4" would be the minimum gap that you'd want to leave. If you're going to have some type of trim to cover that gap, just leave it open, since it won't show anyway. If not, use a color-matched caulk to fill it.

    Definitely do not use grout, mortar, or any other hard material to fill the joint, or it's all for nothing.
