We have a Lilac home that is 4 years old. In the last week the master walk-in shower has developed hairline cracks in about 10
of the 2" floor tiles. It is in a diagonal line from the left entrance wall and travels diagonally to the right base of the shower seat.
It isn't tile after tile that has the hairline cracks, it skips a couple and then keeps going in the same direction. In total, about a length of 4 feet. Has anyone had this problem? If so, please let us know what caused it and how & who repaired it. It isn't anywhere else in the shower or bathroom. Thanks for your help.
