The Electric Theatre was built in 1911 by the St. George Amusement Company at a cost of $7,500. Builders include Charlie Whipple, Johnnie Pymm, and Sherman Hardy. The walls of the 220-seat theatre are adobe and are nearly three feet thick. It was the first air-conditioned building in St. George. The theatre opened on September 6, 1911.

R. M. Reber purchased the Electric Theatre in 1930 for $10,000. He remodeled it. A contest offered five dollars to the person who could come up with the best name for the theatre after which it was renamed the Gaiety Theatre.

The Electric Theatre was totally renovated in 1991 by R. M. Reber. The name Electric Theatre was restored.
