SU 8185 is a small feature of unknown function. It is constructed with the same technique, and is clearly to be associated with, SU 8186 on the opposite (west) side of the basin 8184. All seem to have been constructed together for a single purpose, namely the mixing of mortar. However, it is unclear what precise function 8185 and 8186 served. Perhaps they formed a small ledge, seat, or counter which aided in the work.
