I've literally just had my shower and tiles installation completed but have only just found out about tile and grout sealing (the workmen never mentioned this).
I've been googling on this subject for the past hour or so and there seems to be a divided opinion on weather it’s worth it or not. Some say it is because it’s water resistant and helps prevent mildew etc. Others disagree as they warn that it could discolour the grout.
I would like to hear from you pro's weather or not I should seal both tiles and grout or not at all please?
