ᐅ Is an additional heater recommended in a bathroom with underfloor heating?

Hello everyone,
We are currently planning our new house and have reached the point where we need to decide on an additional fast heating option for our bathroom, one that responds more quickly than the rather slow underfloor heating.
We are considering either a wall-mounted fan heater or an electric towel warmer. We understand that both options have their advantages and disadvantages, but this supplementary heater will only be used during transitional seasons when the underfloor heating is not yet running or has already been turned off.
The bathroom has a floor area of about 18 square meters (living area around 16 square meters (172 square feet) due to the sloping ceiling). The built-in heating system will be an air-to-water heat pump with a controlled ventilation system.
Personally, I’m leaning toward the towel warmer, mostly for aesthetic reasons.
What would you recommend?
Best regards,
Dirk

I think Lexmaul is right here. With heat pumps, much more attention needs to be paid to keeping the flow temperature as low as possible, and the design and pipe spacing for each room must be planned more precisely. Any incorrect sizing or even one degree higher increases electricity consumption and unnecessarily raises heating costs.
With gas or pellet systems, it’s not as critical because the water can be heated to higher temperatures more easily and with less effort compared to a heat pump. So, if for example the bathroom is too cold, you don’t pay as much extra heating cost compared to heat pumps if you simply raise the flow temperature a bit.
But after this discussion, I still don’t know what to choose?? Infrared heating isn’t great, or just good for a short burst of warmth. Towel radiators connected only to underfloor heating tend to collect dust and supposedly don’t provide much benefit either…
That said, I find it strange why underfloor heating would work well but towel radiators wouldn’t? They run at the same temperature all day, so if the towel radiator is 1 m x 2 m (3 ft x 6.5 ft), wouldn’t it simply add 2 square meters (21.5 square feet) of heating surface?
Or what would be the alternative with a heat pump and underfloor heating? With the same insulation and heating system like underfloor heating, a house requires a specific amount of energy to reach a certain temperature. The necessary flow temperature is completely independent of the heat source. So a gas boiler shouldn’t or doesn’t have to heat the water significantly hotter than a heat pump, otherwise the whole house would become too warm.
I'm bringing this topic back up because I'm very interested in it right now. So far, we don't have a towel radiator, but with the colder season approaching, it's really time to get one.
We are considering panel-style towel radiators (I don’t like pipes because of dust). This one measures 184cm by 48cm (72 inches by 19 inches) and can only be operated with a 600-watt heating element, which is installed horizontally at the top. Is 600 watts enough for a bathroom of about 11m² (118 ft²)? What is the difference between 600 watts and 1000 watts? Does it mean that the water inside the radiator won’t get as hot, or just that it takes longer to heat up?

Isn't the heating circuit connected to electricity? Yes, it is. It’s purely electric operation because we have an air-to-water heat pump and the water supply temperature is too low.
Additionally, we do have underfloor heating, even in the shower area. We do not have the heating load calculation since the general contractor handled the construction.

We had to install our socket at about 2.20m (7 feet 3 inches) because of the protection zone, but unfortunately, I can only find radiators with the heating element connection at the bottom.
