A better approach for positioning the rooms is to generate the size of the room first, then randomly determine the (x, y) position within a range that accounts for the size of the room being spawned. This will get you big rooms that can be flush with the boundaries of the tilemap without causing small rooms near the edge to have large amounts of space between it and the boundary.

If we assume that the position of a room is in its top-left corner, then the range for its position would be (0, map_width - room_width) and (0, map_height - room_height). And you can still add a margin afterwards.
