Yes. If you get a twin-panelled radiator, you can slide a piece of board down each end, inside the cross-bracer, to rest on the rad. in/outlets. You can then make a shelf between the uprights, and add cross-pieces above, ladder- fashion. The whole lot can be varnished off and looks great!
We have a smart (chromium plated) device which hooks on our panel radiator in the bathroom. Its particular appeal is that between the two hooks are two pipes, one a smaller diameter than the other so that it slides in and enables lengthening or shortening of the rail to accommodate different sizes of radiators.
I've never seen one a shop (don't shop much) and we didn't buy it, it's the most useful thing we inherited from Spouse's father's house but I'm sure it wasn't a one-off.
The radiated heat from the panel dries and warms the towels hanging on the rail very effectively - when the ch is on of course.
