Combilay under lino?

[blainey]

Hi there
I am laying vinyl sheet flooring in my bathroom. I have taken away the old ceramic tiles and there is a layer of plywood covering the floor. I was wondering if it is ok to use combi lay underlay under the vinyl even though it is meant for laminate flooring. I just want to make the floor more cushioned.
Also- can anyone recommend any adhesive to stick the vinyl down with. Should I use trim around the edges and should i seal it with something around the bottom of the toilet?

Thank you
Alison

you cant use any underlay under vinyl. It will make it to soft and distort like mad looking like the sea. re plywood the floor and then loose lay vinyl. Dont stick it down. Cut a little bit short on every wall and then cover gap with neat bead of silicon. Use masking tape to get neat if not a silicon guru.
