If you can get a longer tub its easier to create a temperature gradient from front to back. We use 400mm long; 200mm wide 100mm high with 100mm hgeat tape at the back. heat cord would be fine but harder to install. If you can get tubs without legs the heat transmits better. most tubs have 1-2 mm lugs which keep them off the floor and get caught when you slide them. I used to gringd them off flat but ended up importing vision tubs from America. Jason has made it easy and now stocks V15 tubs.
