Data release of the objects presented in the paper "Volumetric Rates of Luminous Red Novae and Intermediate Luminosity Red Transients with the Zwicky Transient Facility". This includes multiband optical-near-IR (NIR) lightcurves, optical and NIR spectra of LRNe, ILRTs and possible LBV outbursts presented in the paper. The release also includes Gaussian-Process lightcurve templates of LRNe and ILRTs, that were used to simulate these transients and determine their volumetric rates.
