What is the prescribed legitimate solution for the problem of recurrent janabah, which prevents one from performing ghusl and offering prayers on time?

Frequent states of janaba (major ritual impurity) do not waive the obligation of performing ghusl (ritual bath) for prayer, nor do they permit delaying prayer beyond its appointed time, nor resorting to tayammum (dry ablution) when water is available and one is able to use it. Ghusl is obligatory for every prayer that necessitates it due to janaba, or one must perform ghusl before the prayer to perform it within its time with water purification. Ghusl from janaba is obligatory for every Muslim who finds water and is able to use it. Whoever prays without lawful ritual purity, deeming it permissible, is a disbeliever. Ghusl does not take a long time; it suffices to cover the entire body with water with the intention.
