I installed two 3x5 sheets of backerboard in my tub alcove today. As I read from this forum I should leave a 1/8" gap between the two sheets and fill with thinset and mesh tape.
Now that I have installed this, I keep looking at that gap and fearing that I am inviting problems for a leak. Wouldn't it be better to leave NO gap as that would protect better against water leak?
I've attached a picture. Can someone reassure my fears?
