First let me say hello as this is my first post here. So here is my question I’m installing electric floor heat (110 volt) and want to know if there is a thermostat/timer that can control the in floor heat but also has a secondary timer/switch that I can control a heated towel rack from the same in wall switch. My goal is to minimize the switches on the wall. The heated towel rack would be on a timer only the floor would be thermostat/timer. It can be on the same timer if the thermostat does not interupt that feed. I looked on Google and was not able to find an answer if such a thing exists. Thank you for any help.

Since most towel warmers draw less than a few hundred watts, they can probably be added on to a timer circuit with your underfloor electric floor heat, unless your mats are big enough to max out a circuit by themselves. I would only use the thermostat that came with the heated mats. It's going to be nearly impossible to find a combo unit that would work well with your mats.

The problem is that a floor warming tstat has an in-floor sensor that regulates the temp of the floor. If you include a towel warmer, it will activate whenever the floor does. And, as previously mentioned, you don't want to go beyond the 16a rating (generally speaking) of the tstat. There are no "dual purpose" tstats that I am aware of.
