Bathroom underfloor heating - is this possible?

[scoobydoo99]

Our Bathroom has a concrete floor with underlay and carpet, we'd like to install electric underfloor heating but not raise the floor height too much, if at all. On that basis, we thought a karndean type flooring might work, certainly if combined with the foil type electric underfloor heating.
But it looks to be that the only electric underfloor heating that's suitable for karndean flooring in a bathroom is the wire mat type which will need 2 layers of thick adhesive, along with the insulation boards, possibly making the flooring thicker than we had intended.

Anyone aware of any other options? Is there a foil type flooring suitable for bathrooms and the karndean or amtico type flooring?

Thanks.
