The shower floor heating kits can be tied into floor heating for the rest of the bathroom - allowing for one thermostat to control both areas as long as both areas are using less than 15 amps. When designing installation plans, we design with only one thermostat by default. If you prefer two separate thermostats, it might be a good idea, since the shower floor application is usually thicker and takes longer to heat.
