Is click vinyl waterproof in the bathroom?

Can click vinyl be installed in the bathroom without worries? Click vinyl is also offered for bathrooms.

The clicking joint is not sealed waterproof.
Between the screed and the click vinyl, a waterproof foil can be laid.

Why not?

It is offered for the bathroom after all.

As with all things, it is also a question of dosage here; assuming horror scenarios seems unhelpful to me. Ultimately, you can also lay wood in the bathroom, since after showering you never leave huge puddles, but at least wipe the floor dry. If the product is even designated for wet areas, you are well above this limit. If the bathroom is actually regularly flooded, I would rather address it elsewhere.

Between screed and click vinyl, a waterproof foil can be laid.

If you really have water accumulation under the flooring, everything has gone wrong anyway, no matter which covering you choose. Then the water is between the foil and the covering.......o_Oo_Oo_Oo_O what could possibly be good about that?

By the way, there are also such grout fillers, we used that for the laminate in our kitchen. I would only install vinyl in the bathroom if there are no children living in the house. We have tiles in the bathroom and with the two kids that was often a good choice. There have been no disasters in the kitchen so far, but in the bathroom there is always some mess around the sink and tub, etc.

Use full vinyl. That means without HDF carrier or cork layer as integrated impact sound insulation. The water that does get through cannot harm the vinyl.
