We are lucky enough to have space in both our bathrooms to accommodate a conventional K2 radiator to heat the room and a towel radiator for drying towels. In summer we resort to drying towels the old fashioned way by hanging them outside. The additional heat output provided by the towel radiator allows a slightly smaller K2 than otherwise would have been required to meet the MCS recommendation.

In one en-suite bathroom we have a 180cm high towel rail which isn’t enough wattage really, but the bedroom donates plenty of heat.

In another we simply added an extra small radiator and in a 3rd a towel rail (dual fuel) to add to ufh. But we’ve never need to add in an electrical time slot to supplement heat, even in summer when the heating is off.

I had indigestion with the price of the taller high area ones since we needed two going that route.

Yes I agree.  They are extremely expensive.  I suspect they sell very few of them, so they don’t have the economies of scale of standard radiators.  The 14 week lead time on coloured ones is painful too.
