I'm trying to replace a few broken shower wall tiles which measure out to 4
3/8" square. The tiles I found at Home Depot are 4 1/4".

Is it possible that this size is not made anymore? The house is 21 years
old. I guess I thought HD would have the best selection. My Google search
has not turned up an online store that might have these yet. I thought
someone might point me the right direction and save me some time. Thanks.
