Since some don't have a bidet attachment. The shower head is a wonderful alternative. just sayin'

If you have fresh heads there is less worry. The little bits won't calcify in the lines as they will with a salt water feed.

Short of "absorbent or barrier items" we have never had a problem with a LOW amount of usage (2-6 sheets). Just make sure to pump/hold the button twice as long as you need. 20 seconds to "ALL GONE" add 20 seconds.
