I'm in Canberra and we've recently installed underfloor heating in our bathroom. We only caught the tail end of this winter, but the underfloor heating dries the towels out fine, so don't miss not having heated towel rails. We haven't installed any additional heating, but I'm not expecting to need it. Probably need to have it a full winter to pass final judgement on that though.

Like this? There are several sites you can check out. Some rails are hard-wired and some are plug-in. Different finishes. Not all have the hooks you refer to, but some very nice styles available. This is the only one with hooks that quickly popped up on initial search. Best wishes.

Hi pixiechick1969, Fontaine Industries offers a range of heated towel rails in chrome or black that are also budget friendly! We offer either round or square designs (for your convenience) in various sizes too (550, 640, 800 & 1000). https://fontaineind.com.au/accessories/heated-towel-rail
