Very small ensuite wet underfloor heating

[nick9one1]

I'm renovating our ensuite and would like to install wet underfloor heating.
The room is 2m x 2m.

There is a small conventional rad in there at the moment. I was thinking of swapping it with a low btu towel rad and running wet underfloor heating.

As its such a small toom, can I run this directly from the radiator?

Underfloor should be on its own circuit as the time taken to warm the floor is longer

Have you got an extractor fan?

the reason I ask is I found this online;

Can I Connect the Underfloor Heating to the Radiators Circuit?​

Only if the area isn't greater than 15m2 and the Return Water Temperature Limit valve is being used. If the UFH system is connected to the radiators it can't be controlled individually.

For all rooms greater than 15m2 you need separate primary flow and return pipes from the boiler or you can tee off the main central heating pipes (before the first radiator).

Can I connect the UFH to my radiator circuit?

You actually can use the radiator flow and return but you can't connect directly. There needs to be what's called a FHV- RTL valve installed to control the temps, as suggested.
