Super extra long life (swimming pool) grout?

[KillingTime]

Hi,

Can anyone recommend a tiling grout that is guaranteed to last for 20 -25 years?

I had a tiler / plasterer in tonight to give a quote on a skimming job. We got talking about my bathroom (needs tiling) and I said I was concerned about leaks. He told me to use the grout they use in swimming pools which is guaranteed to last for 25 years (without maintenance).

I can't remember the name of this grout.

Anyway, does anyone here know of a grout that is 'the best' irrespective of cost? I'm not just talking about advertising either (legalised lying). Anyone have experience with the good stuff?

My bathroom cannot leak (and will be tanked also).

Thanks.

Don't know about the 25 year bit.
