Height of skirting above vinyl? Seal the gap?

[smp50]

I'm about to loose-lay (hopefully) some vinyl in a 2x3m bathroom (on concrete). Skirting hasn't been affixed yet so that will go on afterwards. What is an appropriate gap to leave above the vinyl? I won't sit the skirting firmly on top as that would prevent me from removing the vinyl if ever required. Are we talking just a few mm, maybe the thickness of the vinyl again on top (I could use offcuts as a guide)?

And, then, is it conventional to seal the gap some silicone or caulk or something? For water proofing. The vinyl is whiteish, like the skirting, so I could get away with it easily enough.


Thanks,

Simply sit the skirting on top of the sheet edges. Likewise at the threshold bar or under any fixtures.
Stay away from white caulking at floor level, it will quickly dirty and look terrible.
