I'm actually surprised it took that long.
Although showers aren't subject to constant submersion in water, it shows that grout/adhesive is not 'waterproof' as many customers believe it is.
The thing is, once the water has penetrated the grout it's into the substrate, and that starts to spell failure, hence why I tank all showers, even over the bath showers. I only take it up a metre above lip of bath and tank the shower wall and approx. 1m in length on long side of bath.
Interesting to see where the water has actually penetrated. You can see the small dots I suspect where the grout joint is but it concentrates more at one end. Was the box on a slightly uneven surface Deano?
