A chamberpot or receptacle of earthenware or wood that is upturned on its opening, there are those who permit and there are those who forbid, and the halakhah (law) is like those who forbid.

English

It it permitted to recite the Sh'ma in a house in which there is excrement or urine or a chamberpot [used for excrement] or receptacle [used for urine] as long as one has distanced from them the amount that was clarified in Siman 79. And similarly, if one inverts a vessel over them, even though they are with him in the house, behold it is as if they are buried and it is permitted to recite opposite them.
