Expansion gap for vinyl click

[mazdaq]

Laying SPC vinyl click 6mm flooring in 2 bathrooms this week. No glue required. The flooring is replacing existing and there are skirting boards already in place around the edge, which I don't really want to remove. Couple of questions:

1. Do I need an expansion gap for vinyl click? Reading mixed opinions. And if so, how much gap do I need? Small bathrooms. Both roughly 2m x 2m.

2. Would it look better to leave the gap next to the skirting and fill with sealant? Or cut the bottom of the skirting off with a multitool and slide under?

3. Are there any tips for cutting the flooring round a quadrant shower tray?

Unless removing skirting you would normally cover expansion gap with a trim.

That size 2mm gap on each side should be ok. Use template paper to mar the curved cuts
