Decided to replace the radiator in the bathroom with a towel rail. Chose a chrome ladder-style towel rail from B&Q and had the plumber fix it. It is so much better than a radiator, looks better in the bathroom, is more efficient use of space; I was asking myself why the builders couldn’t have put one in to start with. Most of all; luxuriously warm towel to dry on (assuming the heating is on, of course)!!!
