A bedroom is a living area that serves a variety of dignified functions. It therefore requires a mezuzah even though people sometimes expose themselves while getting dressed in the room or a young child’s dirty diapers are changed there.<a href="#_ftn1" name="_ftnref1"><sup>[1]</sup></a> However, the mezuzah should be encased in an opaque cover in a room where adults or children might expose themselves.<a href="#_ftn2" name="_ftnref2"><sup>[2]</sup></a> This would apply even if the mezuzah is on the outside of the door, as sometimes the door is inadvertently left open.<a href="#_ftn3" name="_ftnref3"><sup>[3]</sup></a> A mezuzah inside a room occupied by a married couple requires two covers, one of which must be opaque.<a href="#_ftn4" name="_ftnref4"><sup>[4]</sup></a> However, if a closed door intervenes between the room and the mezuzah, a single cover is sufficient. An opaque cover is also advisable in a room where soiled diapers are changed.<a href="#_ftn5" name="_ftnref5"><sup>[5]</sup></a> A garbage pail, changing table, or even a mop and bucket should not be placed within four <em>amot</em> of the mezuzah, even if it has an opaque covering.<a href="#_ftn6" name="_ftnref6"><sup>[6]</sup></a> This cover may be transparent, unless there is a chance that people will expose themselves when the door is partially open.<a href="#_ftn7" name="_ftnref7"><sup>[7]</sup></a> If one affixes a mezuzah on the doorway of a large closet inside the master bedroom, it should be placed on the closet side of the door, and the door should be closed during relations.<a href="#_ftn8" name="_ftnref8"><sup>[8]</sup></a> It is advisable to cover it anyways with a double cover, in case the door is inadvertently left open.<a href="#_ftn9" name="_ftnref9"><sup>[9]</sup></a> To make a double covering, wrap the mezuzah in a small piece of paper and place it in an opaque cover, before affixing to the post.<a href="#_ftn10" name="_ftnref10"><sup>[10]</sup></a> The plastic wrapping that is often found on a mezuzah at the time of purchase is there to protect it from moisture, and is not considered a covering.<a href="#_ftn11" name="_ftnref11"><sup>[11]</sup></a> <a href="#_ftnref1" name="_ftn1">[1]</a> <em>Rema</em> <em>Y.D.</em> 286:2 and <em>B</em><em>e</em><em>i</em><em>’</em><em>ur Ha</em><em>G</em><em>ra</em> 286:4. <a href="#_ftnref2" name="_ftn2">[2]</a> <em>Aruch HaShulchan </em> <em>Y.D.</em> 286:10; <em>Mishnah Berurah</em> 84:7; <em>Darchei Moshe</em> <em>Y.D.</em> 286:2. <a href="#_ftnref3" name="_ftn3">[3]</a> <em>Sha’arei HaMezuzah</em> 18:9. <a href="#_ftnref4" name="_ftn4">[4]</a> <em>Magen Avraham</em> 40:2. <a href="#_ftnref5" name="_ftn5">[5]</a> <em>Birchei Yosef</em> 286:4; <em>Kuntres HaMezuzah</em> 286:107,110; <em>Agur B’ohalecha</em> 32:59; <em>Sha’arei HaMezuzah</em> 18:8. <a href="#_ftnref6" name="_ftn6">[6]</a> <em>Pitchei Teshuvah</em> 286:7. <a href="#_ftnref7" name="_ftn7">[7]</a> <em>Aruch HaShulchan </em> <em>Y.D.</em> 286:10; <em>Mishnah Berurah</em> 84:7; <em>Darchei Moshe</em> <em>Y.D.</em> 286:2. <a href="#_ftnref8" name="_ftn8">[8]</a> <em>Shach</em> <em>Y.D.</em> 286:10. <a href="#_ftnref9" name="_ftn9">[9]</a> <em>Sha’arei HaMezuzah</em> 18:9. <a href="#_ftnref10" name="_ftn10">[10]</a> <em>Mishna</em><em>h</em><em> B</em><em>e</em><em>rurah</em> 40:7, citing <em>Ch</em><em>oc</em><em>hmas Adam</em>; <em>Chovas HaDar</em> 1:7:32. <em>Agur B’ohalecha</em> (32:72:187) writes that this is the custom.
