BAL Microflex / Superflex in bathroom

[iwaters]

What is the best grout to use on floors and walls in a shower enclosure and bathroom floor? The floor will be overboarded floorboards.

Should I use the Microflex wide joint or is the superflex wide joint ok? It's a small area and would ideally like to use the same grout for both rather than buy two bags.

Recently posted another thread about the use of Microflex on suspended timber floors. It’s not primarily rated as a flexible grout unless you modify it with Admix AD1 & even then, there seems to be some doubt in the BAL spec sheets as it’s got a big cross next to “timber floors”. I use Microflex all the time on walls but only ever use Superflex on floors; for the sake of 15 quid or so, I don’t consider it worth the risk.

Thanks Richard. I'll buy both then.
