"The funnel (center left, at front of opening slot, look for the black drain hole) is hand-shaped cement mortar over expanded metal lath, placed to catch urine flow from sitting persons of either gender (men can use it standing as well, although it's less messy to just go outside). I fit black plastic pipe into the lath funnel, and plugged the opening with a wad of paper while I worked the cement. The original funnel extended a bit too far back, so I cut it down with a masonry saw and hammer and chisels. A plastic bottle with the bottom cut out also works, especially for determining optimum placement | "The funnel (center left, at front of opening slot, look for the black drain hole) is hand-shaped cement mortar over expanded metal lath, placed to catch urine flow from sitting persons of either gender (men can use it standing as well, although it's less messy to just go outside).
