The Latrine is a 32' x 18' structure typical of the sanitation buildings constructed in the state park system. The building is built entirely of local split stone with the exception of two areas between the windows on the front and rear facades which are sheathed with rough clapboards. Stone screens, 9'6" long by 5'6" wide that rise to a height of 5', define the entrances to the building. Window openings are 6-light casements.

The building was remodeled in 1959, at which time skylights were added and the original cedar shingles were replaced with asphalt. In 1963 the interior fixtures were replaced.
