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.

lots of advice in response to your question on Google...i like to align with top of vanity at about 850 to 900mm above the floor but, if you need a towel and grab rail for safety of disabled and elderly there are specific recommendations but main criteria should be comfort of main users and size of your towels

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

the heated floor can be installed like an extra thin electric blanket under new tiles (or carpet or timber etc) and we have a portable small electric plug in floor mat under a rug in a study ...not really suitable for a quick heat but ideal for a cold place where the inbuilt timers warms up the floor to suit early morning and late evening and suprisingly cheap to buy but not cheap to run for big rooms .. we live in a cold climate and have underfloor heating under tiles in bathrooms, laundry and mudroom, under fitted carpet down a long hallway and under a loose floor mat to keep feet warm while sitting at a desk in the study and its excellent..... usually available from tile shops and on line suppliers in a range of suitable sizes including by the square metre and installed by tilers and electrician after new waterproofing and before tiles...i think the last time we installed the underfloor heating for a modest sized bathroom was well under $1000 including installation and well worth the cost
