Do I have to say Bismillah before wudu?

It depends on the school, but it is recommended for everyone. Most scholars say saying "Bismillah" (in the name of Allah) at the start of wudu is a sunnah, so your wudu is valid even if you forget. The Hanbali school treats it as obligatory, but drops the duty if you forget. Either way, it is easy to say, so say it.
What the hadith says
Several reports say that the Prophet ﷺ said there is no wudu for the one who doesn't mention Allah's name over it. One version reads: "The prayer of a person who does not perform ablution is not valid, and the ablution of a person who does not mention the name of Allah is not valid" (Sunan Abi Dawud 101).
The Prophet ﷺ also practiced it. When some Companions needed water for wudu, he said, "Perform wudu in the name of Allah" (Sunan an-Nasa'i 78).
Why scholars differ
The difference is about how strong the reports are and how to understand their wording:
- Hanafi, Maliki and Shafi'i schools: the reports are not strong enough to make it a condition, or "not valid" means "not complete". So it is a sunnah that brings extra reward.
- Hanbali school: several chains support each other, so it is obligatory, but it's forgiven if you forget.
In practical terms, a person who forgets it should not repeat wudu in any school. You can add it as soon as you remember, even in the middle of wudu.
What to say
The short form is enough: Bismillah, "In the name of Allah". You say it before washing your hands, the first step of wudu. There is no need for a long phrase. See What does "Bismillah" mean?
If you are in a restroom area, you may say it silently in your heart.
After wudu
The beginning has bismillah, and the end has a dua. Saying the shahada and a short supplication after wudu is a beautiful habit. See What dua do I say after wudu?
Both together bring a sense of purpose to something that can otherwise become a routine. For a full guide, see What are the sunnahs of wudu?
- Saying Bismillah at the start of wudu is at least a sunnah.
- The Hanbali school considers it obligatory, but excused if forgotten.
- Nobody needs to repeat wudu because they forgot to say it.
- Saying it silently is fine when you're in a restroom area.

Usually not. A loose ring or watch is fine if water reaches the skin; take it off or move it if it is tight, so your wudu is valid.
