    Hi all,

    I've a potential client looking to install sheet vinyl in a small downstairs WC over existing tiles.

    I haven't seen the job yet so not 100% sure on best route forward. Client wants Izotherm boards laid first then install the vinyl.

    Does anyone know if this will work? I've had a search around and they claim they are suitable but look like the green fibre boards for laminate....

    For a bathroom I'd say screed over the tiles Its not worth the hassle for what it is

    My thoughts (and suggestion to the client) was that. Apparently it’s too cold though so wants something warmer...

    You could use Jumpax on it then glue to vinyl to that. Great for keeping the floor warm.

    Thanks all.

    Daz. How easy is Jumpax to fit. I’ve never worked with it?

    If it's just a wc,i'd just put the top layer of jumpax together then template it,like you would with plywood, then lay out the bottom sheets, place the top ones you've just cut on top,without peeling the film and and draw or cut round it
