Can I stain my grout?

[Scatts570]

we chose what we thought was a great greyish grout colour to go with our White Porcelanosa tiles and it looks..........awful. Missus is really peeved. The bathroom is fully tiled and to re-grout is a) a nightmare job full of risk of damage to tiles and b) getting a competent person to actually do it is going to be difficult and expensive.

Is there a stain/paint that’s recommended that I could apply to it to stain it a more White colour? Obviously without staining the tiles.

I’ve see some on the internet, but nothing seems to get a good review. 1st hand experience would be good.

Before anyone asks ‘the missus can’t live with it’. She hates it and nothing’s going to change that mind. I get the luxury or hearing about it everyday!

I’ve been informed by the OH that the grout is not grey, but ‘Jasmine White’. So it’s a slightly muted white and not the white she wants.
