I installed a 150 watt mating system in my bathroom and it's brilliant, got a lifetime guarantee on the heating element, I did put 2 thermostats in but only wired one up, if that packs up there's the other to fall back on, it's surprising how nicely it warms the bathroom up,
My feet are always cold, I was so done putting on 2 or 3 pairs of socks every winter. My husband says I'm crazy and that the radiators in our home provide just enough heat. Not for me, apparently. This winter, I convinced my husband to install electric underfloor heating. We bought it from https://bathroom-supermarket.co.uk/collections/radiators. We chose cables (electrical) as they say it can be more cost-effective, and the heat lasts better. I can tell you that this was one of the best choices we've ever made.
