The electroweak phase transition in grand unified theory inspired gauge-Higgs unification is shown to be weakly first order and occurs at , which is very similar to the behavior in the standard model in perturbation theory. A new phase appears at higher temperatures. () and () phases become almost degenerate above where is the Kaluza-Klein mass scale (typically around 13 TeV) and is the Aharonov-Bohm phase along the fifth dimension. The two phases become degenerate at . As the temperature drops in the evolution of the early Universe the phase becomes unstable. The tunneling rate from the phase to the phase becomes sizable and a first-order phase transition takes place at . The amount of gravitational waves produced in this left-right phase transition is small, far below the reach of the sensitivity of LISA. A detailed analysis of the phase is also given. It is shown that the boson, boson and photon, with varying from 0 to , are transformed to gauge bosons in the phase. Gauge couplings and wave functions of quarks, leptons, and dark fermions in the phase are determined.
