We had a new family bathroom only 6 months ago but I am so cross with my sons who ranfge on age from 15 to 23 , already the loo seat is broken , cannot understand why this is , and the grouting around the loo is turning yellow.Its cleaned regularly but if they wee on the wall after I have gone to work and don't clean it up ( will never admit it is them) until after work the stain is already coming .Sometimes I hate having boys , they really don't care it seems .I have tried everything to stop them doing this after 20 years I am baffled
