I foresee water getting in the gap and seams when cleaning the floor.
How to hide a huge gap between tile and wall.
Fill gaps larger than 1 8 inch.
The steel studs are perfectly straight.
The other advantage to using steel studs in these areas is they don t warp or shrink.
Great remodelers and builders consider using galvanized steel studs in locations where there will be tile.
Apply the caulk with a caulking gun.
If you have tile on the wall adjoining the tub select a caulk that matches the color of the grout.
Choose a color that matches the countertop and spread a thin continuous bead with no voids.
The line will continue maintaining caulk gap regardless of the gap of the wall to counter.
Tool the caulk by drawing your finger along it to form a concave surface.
The only thing to cover the gap would be to use 1 4 round molding.
If installed plumb and square the finished tile work looks amazing.
If your gap is smaller than 1 8 inch in width use regular caulk.
Your tile person will take the largest gap and run a tape line using that as the thickness or the caulk.
