Ok so I was thinking of using flexwatt for my tub setup and was wondering if i just need one piece of 4", hook 2 pcs. of 4" side by side or use one 11" piece and cut it to size. half of the tub measures 13"x8"(yes it will be hooked up to a Ranco thermostat). I'm new in the flexwatt area so any help would be geat thanks.
