Wat Yi Kham was located off the city island in the southern area of Ayutthaya in Samphao Lom Sub-district (1).
The site sits on the right bank of the Chao Phraya River. To the west stood Wat Tha Sak (defunct), and on the east Wat Khun Phrom.
In situ, there are no traces of the former temple, at least above ground level. The site is covered in vegetation.
The monastery's historical background and period of construction are unknown.
Wat Yi Kham is indicated on a 19th-century map, on Phraya Boran Ratchathanin's (PBR) map drafted in 1926 CE and on Fine Arts Department (FAD) maps.
On a FAD map drafted in 1974 CE, a canal is indicated between Wat Yi Kham and Wat Tha Sak, leading from the Chao Phraya River south towards Wat Phraya Kong.
On the 2007 FAD GIS map, the locations of Wat Yi Kham and Wat Tha Sak are swapped, notwithstanding the alignment of the monasteries (east to west) on the 19th-century map and PBR map being Wat Khun Phrom - Wat Yi Kham - Wat Pa Sak - Wat Chi Thammo.
Wat Yi Kham should have been situated in geographical coordinates: 14° 20' 43.76" N, 100° 34' 8.44" E.

(1) Sub-district called after the village Ban Samphao Lom near the Chao Phraya River. The village is on the Monthon Krung Kao map (1916 CE). John Bowring (1857, London, John W. Parker and Son, West Strand), in his book ‘The Kingdom and People of Siam’, wrote: "Between the modern and the ancient capital, Bangkok and Ayuthia, is a village called the “Sunken Ship,” the houses being erected round a mast which towers above the surface at low water."
