Quoting a job for a couple of 'Europeans', They say that on the Continent they don't use a 'chalk' based grout? So 1st question, what type do they use?

Secondly, Their main concern is the grout in the shower areas going mouldy after a time. What is the best grout to use or is there a sealer I can use. Have talked them out of epoxy for the moment if that is an answer.
