Can I install laminate next to tile without using T-moulding?
Manufacturers require expansion around the entire perimeter of your floating floor. Depends on whether or not you want to maintain your warranty. If you don't care, fly at er. You may or may not end up with issues. Depending on the height of the tile, I like to use an Edge Mold which butts up to the tile instead of overlapping it. It still overlaps the laminate, offering a warranty approved solution. Last week I had to deny a warranty claim by a builder who butted all his floating engineered hardwood tight to tile. The flooring started to squeak a couple months after completion. Badly.  Sorry "builder". He was out a substantial sum. Your 10x11 room may survive unscathed.
