Grout cracking in shower

[uncleg]

Hi,

Following another post, which you guys have helped me with, I also have an issue with some of the tiles in my shower.

As it is used a lot, some cracks have appeared in the grout on say two tiles, which my tiler will prob re grout when he comes tomorrow....

Will I always have this issue, shall I use Aquamix sealant on the grout in the shower to help? I am just concerned more cracks will appear over time and maybe if water gets in, the tiles will fall off, bit extreme but you never know...

I am sure none of this tanking I hear of was considered at the time.....

Thanks

What tiles do you have in the shower ?

They are Porcelain grey with a matt finish, the grout is grey as well.

The ensuite, which touch wood is okay for now.... they are ceramic with a gloss finish.

BAL microflex grey grout was used for the wall and floors.......

What was the substrate and are there any silicon joints in the internal corners ?

I will have to ask on the substrate....

The shower is a walk in shower in the corner on the bathroom, so the corner does have a silicone seal.....
