I'm planning a bathroom remodel and wanted to replace my existing bathroom rad (will be too small and cast iron) with a towel rail and worked out I need something in the region of 1200w, am I being dense the largest towel rail I can find is only half that power rating? For the space I have (approx 600mm wide & behind door) standard rads aren't really tall enough, can you recommend any other options? Thanks in advance.
