Best radiator for cold bathroom?

Hi
We re-did our bathroom about 18 months ago and put in a big towel radiator like this one -

While it gets warm and dries the towels, it doesn't heat the room at all.

The bathroom isn't huge, but has two outside walls (solid stone) so is really cold and the condensation when we shower is terrible (walls running, windows moulding...).

Can anyone advise what type of radiator we should put in? I'm tempted by these:

but I'm not sure if they work as well as a bog-standard radiator. I'm a bit dim when it comes to BTU and outputs but it looks like they are 3 times warmer than our current towel radiator? Is this right?

For info - our c/h system works fine - we just had a new boiler fitted and the system cleaned, so it's not a problem with how the radiator works.

Any advice very welcome!
Thanks

Towel rails simply warm towels as they are usually clad in one and so do not emit much heat.
A standard convector radiator will emit much more heat unless of course it is also covered by a towel.

The models with columns in the centre will emit more heat but not as much as a panel convector model.

btu's have gone a bit out of style a while ago; it has been the norm for years to work in (k)w, which is a lot easier.
a 2000 watt rad gives the same heat as a 2000 watt electric heater, and most people have an idea of what that is.
the tiny towel rail probably gives something in the range of 300 watt, which you can halve when it is covered with a towel, so you need something decidedly bigger.

Towel ladders look good. Nice warm fluffy towels when you step out of the shower.... and on to a cold tiled floor in a cold room because effectively the heat emittor has got a jacket (towel) over it and cannot put out the heat into the room required to raise it to a comfortable level. The circulating hot central heating water goes in hot and returns out just a little colder. The drop from flow (going in) to return (out back to the boiler) should be at least 10 deg c. All too often I have seen wholly inadequately sized rads/ladders in bathrooms and poor ventilation.
Mouldy, wet walls (condensation) mean that the room isn't ventilated well.... open a window...er? not an option if the room is fer fer fereeezin cold to start off with.
Absence or a sparse minimum of cavity and insulation between internal and externall walls (solid stone and 2 externalwalls) does't help either. Add this into the equation and you've got a problem.
A timed extractor with a mechanically shuttered louvred grille and a timed over-run (still works for a time even when the bathroom has been vacated and light turned off) might help somewhat with the mould.... but will still suck out not just moist but warm air too!
Heat rises. What is on the bathroom floor.... ever considered underfloor heating? Could this be an option?
Get a larger ladder installed... use it for warming drying off towels and use a conveniently placed chrome rail to place large bath towels on onstead of leaving them on the ladder.
Have you been ill advised by a salesman? A bathroom installer (tiler plumber)? Has cost cutting been an option when the refit was carried out?
