Small radiator help!

[Notnecessary]

I'm starting to pull my hair out, we need a narrow style radiator for our downstairs w/c, no more than 300mm width and 400mm height, which seems impossible to find. The ones which come up in my search are 300mm x1800mm which is not what I'm looking for.
Does anyone have any idea where I could find a small rad please?

Would this work?

I should add the size is correct and I guess it could be fitted horizontally or vertically.

Unfortunately it wouldn't work. Because of the rad position on the wall it cant be wider than 300mm otherwise it will clash with a sink unit.

How about this one OP? www.bestheating.com/milano-isabel-4-column-cast-iron-radiator-357mm-tall-full-polish-multiple-sizes-available-103653

It's 271mm wide and 357mm tall.

You can get skirting board with heat in it - would something like that work?

Try eastbrook - they have one 360x400?

You can review this page, and you might find the measurements you’re looking for. elegant-radiators.co.uk/collections/chrome-towel-radiator

The reason is probably that 300x400 is barely worth having in terms of heat output. Hardly anyone would go to the expense and bother of fitting one of those because the power output would be so low it would barely make a different to the room anyway.

My guess is the output rating for a double of that size would be about 300W.

Myabe you could get a small glass panel heater or something like that instead.
