I've just had a bathroom retiled and have just noticed there is a cracked tile at the bottom of the shower where the shower door meets the wall, basically it looks like he has overtightened when fixing the door frame to the wall. Should I be worried, is water likely to seep in over time and cause the tiles to blow? Is it unreasonable to ask him to remove the shower door and replace the cracked tile? I think he has noticed the crack as the sealant on the inside covers the crack which is a couple of inches above the shower tray.
Any advice appreciated before I tackle the plumber.
