Grout changing colour when wet, is this normal?

[D1nhs]

Just finished my bathroom project.

I installed a new shower, with tanked walls and aquapanel.

When grouting i used "Bal Grout" that all is says on the bag, which is greeny blue and states "suitable for swimming pools".

Question is, when showering, i notice that when wet the grout turns into a darker shade, clearly absorbing water, is this normal?

Have i got my mix wrong? Have i used the wrong grout?

There is no signs of leaks, but if ive done something wrong id rather fix i now.


Thanks fellas!

Quite normal. Water will soak into grout - that's why you tank the walls.

Thanks Gcol, been reading posts about Epoxy grout etc, was starting think i had used the wrong grout.
