options for cast iron radiators

Can anyone advise me as to what options I have for updating a one pipe steam system that has cast iron radiators? Is baseboard a possible choice, along with,
what can be done with putting heat in the bathroom floor?
The house where this is located is currently under renovation. So you might say I can be open to ideas!
Please advise!

    Baseboard on steam

    must be connected 2-pipe rather than 1-pipe, since there is not enough room in baseboard for the steam and the water to get out of each other's way. The only exception is a very short length of cast-iron baseboard- under 3 feet or so. So you'd have a lot of repiping to do if you switched to baseboard.

    If you want radiant in a floor, you'll have to run a hot-water zone off the existing boiler.

    You might be able to find radiators of trimmer design that would still give off enough heat for the rooms. Do a heat-loss calculation to be sure of the amount of heat you need.

    If you go steam base board you need to pipe it two pipe .
    Burnham makes a very ornate radiator.

    Yes you can run a radiant loop off a steam boiler. You need to install a heat exchanger and run a hydronic loop off it.

    Hot Water Cast Iron Replacement Radiator

    I am looking for a hot water cast iron radiator approximately 24" long x 30" high x 10" thick. I believe it has 3/4" openings at each end on the bottom with a small vent opening at the top. It is in a 100 year old victorian home that we are trying to keep close to original. Ryan will trim it out with copper piping.

    Can you help me out or tell me where to look. You where referred by Dave King / Burnham Corporation.
