An Art In Transit artwork The Waters Are Blue, Yet I Pine For You by Sim Chi Yin is displayed at this station, along with a mural entitled Riding the Waves of Change by students from Tanjong Katong Girls School.

[5] The contract for the design and construction of Tanjong Katong station was awarded to Woh Hup (Private) Limited for S$146 million in April 2016.

[11][12] Initially expected to open in 2023, the restrictions on the construction of the station due to the COVID-19 pandemic led to delays, and the date was pushed to 2024.

[27] The Waters Are Blue, yet I Pine for You by Sim Chi Yin is displayed at this station as part of the Art in Transit programme, a showcase of public artworks on the MRT network.

[28] The artwork, which the title was derived from the first stanza of local folk song Di Tanjung Katong,[28] is a 11.3 m (37 ft) collage on a three-storey wall near the escalators connecting the station's main concourse to the upper and lower platforms.

[29] To portray Tanjong Katong's past and memories, the work combines archival photographs with Sim's images of the present,[28] superimposed over a photo of the former Big Splash water park.

[31][32] The mural portrays the Mountbatten Community playing with clay soldiers and reenacting the last National Day Parade held at the former Kallang Stadium.
