Ubāns together with his family went to Russia, where for a short while he studied in Penza Art School.
In 1925, he was addressed by Vilhelms Purvītis and took a job in Art Academy of Latvia as a teacher of painting.
Konrāds Ubāns is noted mostly for his landscape paintings and the poetic and intimate atmosphere within them.
He mostly painted landscapes of Riga outskirts in Pārdaugava and Daugava river valley especially around Koknese.
Real maturity in his work can be seen as early as his paintings from the 1920s, when he richly uses motifs and atmosphere of impressionism.
