ᐅ Is underfloor heating in the bathroom sufficient, or is an additional heater—such as a wall-mounted heater—needed?

Good morning,
The heating system in our new build is scheduled to be installed in the coming weeks.
However, I am concerned whether the heating output of the underfloor heating in the bathroom will be sufficient.
Therefore, there are three options:
1. Plan for a wall heating system right away, connected to the underfloor heating
2. Connect a towel radiator to the underfloor heating
3. Use an electric towel radiator
Now the questions. Approximately how much extra cost would option 1 involve for a 16m² (172 sq ft) bathroom layout?
Option 2 seems more viable for me, especially since my partner wants it and it would be sufficient if it only gets lukewarm due to the low flow temperature.
Option 3 is what the heating installer suggests, but I’m not keen on it because of electricity costs and efficiency. However, it can be added later if the heating output really isn’t enough.
Who has experience with any of these options?

The issue with towel warmers connected to underfloor heating is simply the low supply temperature of the underfloor heating system.
Of course, if the towel warmer is properly sized, it can provide additional heating for the bathroom. However, in my opinion, it no longer fulfills its primary purpose, which is to warm the towels to a cozy temperature.
We have, in addition to underfloor heating, a purely electric towel warmer, which we actually only use to warm the towels.
The underfloor heating alone is completely sufficient to keep the bathroom at a comfortable temperature.
Best regards,
Dirk

A towel warmer connected to the underfloor heating only works effectively if the underfloor heating operates at high supply temperatures; otherwise, a "lukewarm" towel warmer is of limited use.
If you interfere with the underfloor heating by adding an electric heating element, your heating system will shut down because excessively hot water will be returned.
So, the proper approach with underfloor heating is either a separate towel radiator with an electric heating cartridge, a separate supplementary heater (infrared), or no additional heating at all—after all, the underfloor heating might be sufficient.
For example, in our case, I would personally prefer an additional wall heater, but maybe that will be added later. The spacing of the four pipes should definitely not be less than 10cm (4 inches); otherwise, it could get quite cold.

Yes, but I don’t mind the low temperature as long as the radiator still heats the room and provides a cozy temperature. It wouldn’t be an issue if the towels don’t get nicely warm within 5 minutes. We currently don’t have a towel warmer at all, and the towels are always “cold.”
So, what I’m hearing here is that a towel warmer connected to underfloor heating PLUS an electric cartridge doesn’t make sense. It should either be connected only to the underfloor heating (which is basically like a wall heating) or be electric only...

Based on my own experience, I would recommend a purely electric towel warmer. Ours can be programmed to heat the bathroom and towels automatically at specific times (currently in the morning when we get up and in the evening when we usually go to bed).
The rest of the day and night it stays off to save energy. The underfloor heating maintains our bathroom at a constant 23°C (73°F).
Of course, the towel warmer can also be turned on manually at any time—it then takes about 20 to 30 minutes for the bathroom to reach a comfortable temperature.

Dirk
