Standing for the berachah upon washing for bread

Hi,

Generally, a berachah recited before performing a mitzvah should be recited while standing. However, the berachah upon the ritual netilat yadayim washing for bread may be different because it leads to eating, and because the act of netilat yadayim itself may be performed while seated. Therefore, there is ample room to contend that one may sit for this berachah.

(Rivivot Ephraim 1:125)

Have a great day,
