I'm looking to replace the radiator in my upstairs bathroom and I'm
considering under floor heating.

Is it possible to remove the radiator and attach a long length of
plastic piping in its place and coil this under the floor? Would this
give the same affect as under floor heating?
I've did this a few months back in a bathroom I was plumbing for
a friend. The thinking was that the radiator pipework runs under
a bit of the floor and generates a very nice effect. They wanted
to get rid of the radiator, so I basically snaked more heating
pipework under the floor. I used a couple of runs of 10mm copper,
and because of copper's poor emissivity, lightly sprayed the top
with black paint. A TRV was fitted poking out of pipework boxing
(also a bleeding point). A run of the heating system seemed to
indicate it is likely to work, but it wasn't cold at the time,
so I need to wait and see.

It was back in August when I wrote that.
Now that the heating has been on, I'm told it's working very well.
Ceramic tiled floor doesn't feel hot, but it's not cold either,
and the bathroom temperature feels comfortable.

Thats pretty much what you always feel with UFH. No hot spots,
occasionally warm spots, and generally comfortable.
