Radiant sort of?

Hello
Hope no one minds I joined this forum to get an answer to question. I removed a baseboard hot water convector from a small 5x7 bathroom to tile the floor. The floor is finished but I am contemplating not re-installing a new convector. It has been very cold 11F and the bathroom stays around 70F. I am wondering if a looped a couple of copper pipes suspended in the floor joist below "basement" and insulate the bay underneath? I can't use PEX the water temp is too high, and the hydronic system is a one pipe diverter tee style flow so it would not interfere with other convectors. I would avoid the toilet and vanity areas, just maybe two bays from the door to the tub. Anybody ever seen this done before? The bathroom is so small it actually seems bigger with out the convector.
Thanks
Matt

    11 degrees and you have 75 degrees? Probably don’t need anything, but piping in a towel warmer might be nice.

    There was an error rendering this rich post.

    Plain copper pipe / tube does not radiate well. Until it becomes "fintube".

    Water temp is too high for PEX? How hot is it?

    I’d look into a small electric towel bar, quick heat up, individual control. You may end up using year around

    I have done it with 5/8 pex going from baseboard to baseboard in a series loop, and it worked nice. In my case, there was baseboard installed in the bathroom, and I just wanted to warm the floor up a bit. Worked great.
