Shower Cubicle Leak

[pancaz]

Hello

Thanks for reading my post.

I had a new shower cubicle installed by a Builder around 9 months back. We noticed some leak and water coming out from underneath the shower tray and reported this to Builder. There was some grout missing/cracked which he came back and fixed. This completely stopped the leak. It's been 3-4 Months and now it's leaking again. I cannot see any crack in the grout and now confuse what could cause it. It's not leaking from shower trap as I can look underneath the tray and see it. It's coming from one side of the wall where shower is so makes me think it could be shower plumbing (which is now in stud wall and tiled so not sure how to chek) or again any grouting/silicon issue. Could anyone please suggest how could we track the leak?

Many thanks in advance

Don't use the shower for 24hr's and see if it is still leaking,if so then then problem would be the supply pipework.

If dry then I would say faulty silicone.
