Type of toilet
A telescopic toilet, retractable toilet, or pop-up toilet, is a type of toilet which is stored underground and then raised (usually hydraulically) above ground when in use.[1][2][3][4]
A very common type of telescopic toilet is a telescopic urinal, and they have often been employed at nighttimes or on weekends to discourage street urination.[2][5]
