Grout Sealant to finish a tile job... or not?

My Dad was a contractor for years, and him and I are doing a bathroom renovation on a house that I have purchased. We are installing 12x24" porcelain tile on the tub surround. The tile is a White Marble looking porcelain, and I would love to put matvihing grout to make a nice clean finish.

My dad is 100% against using sealant on the grout because he said it isn't doesn't always work 100% and then you have mildew that can get built up behind the sealant.

I figure NOT sealing it, seems like a bad idea.

I think the tiles and grout should be cleaned often whether you decide to use grout sealer or not. I think I Wouldn't us it as I think grout should breath as concrete does. Grout slants really haven't been around for very long and they haven't been introduced to solve any major problems as grout has been very durable over many years when installed properly. This could be one of those things to add extra material costs to sway people to purchase. But overall if its your work and your house the best way to know if it really makes a difference in a way that you like is to try and use grout sealant and compare it to not using grout sealant and gather what you have learned and teach people what you have learned in the future.

I hope all goes well!
