    I've been looking for radiators (well, towel rails really) for a while. We only need a tiny wattage, but the towel radiators are either really ugly, or really expensive. Eg, this Italian site has some nice ones, but they're over £1000 each: http://www.sciroccoh.it/en/prodotti/design-collection-en/

    I was wondering how hard it would be to make one? Surely there's not much to them. I was wondering if I could ask a metal worker to weld one for me out of box sections of stainless steel or aluminium. Does anybody have any thoughts?

    how about buying one ?

    Thanks gg! I just don't like the look of most standard radiators. I was wondering if I could make something more interesting.

    Whilst home made rads are theoretically possible, you may find in the end they cost more in labour.
    A while ago I asked a local, well equipped, very reputable, engineering company to do a radiator repair/modification. and they advised against it. They said they couldn't guarantee the welds would be pressure/watertight.

    What look do you like? Flat panel, artistic metalwork, there are literally 000s of designs.

    I really like this one: http://www.sciroccoh.it/en/prodotto/snake-4/

    ...other than the cost!

    Good call owlman! This one is not bad, and not too expensive: https://warmehaus.co.uk/delta-1380-x-600mm-sand-grey-designer-heated-towel-rail.html

    If you intend to have an electric rad,- you didn't say, don't be put off by buying a standard one and doing a DIY conversion. It's dead easy, I've done it, and the insert heating elements and controls work really well.

    Thanks @owlman - the plan is to have wet rads / towel rails, but thanks for the tip.

    Hi Pilgrim,
    Electric towel rads., ( in case you misunderstood ), are wet but their heat source is an insert heating element and thermostat. I directed the incoming 230V supply via a simple 24hr timer so it operates independently of my house CH. I find that especially useful in Spring and Autumn.

    Thanks @owlman, yes I understood. Electric or dual system sounds useful in a range of circumstances.

    Yes, this was what occurred to me first, but they all look a bit 'immediate' as my dad would say.

    Have you seen the price of the ones linked above? It would be quite a bit of labour.

    Surely I just need a few pieces of steel box section, 3 threaded fittings, and mounting points?

    The radiator you first posted is very slick looking. You could make one yourself but it might be hard to get that level of finish.

    If you were welding one it would be better to go for stainless IMO, rather than aluminium. You can get box section SS with a gloss or matt finish and square edge corners rather than rounded corners like you would get with the standard mild steel. You then need to cut accurately to have nice mitres.

    If you can find someone locally with TIG welding skills the they could do the welding for you. I doubt whether they would pressure test for you though. Make sure you clean the metal thoroughly with thinners and abrasives as contamination will affect the weld.

    You can pressure test Diy. I have done this when I made a boiler a while back. You need to adapt the plumbing fitting to take an air compressor and pump it up to whatever your target value is. It's obviously better to have the welder available during pressure testing so that you can fix any potential leaks.

    Its doable, if there is a will. And don't underestimate the value of having made it yourself. :)
