The laws of a Mikva are of the most complex that exist. They are riddled with minutiae and disagreement among even later day Rabbis. Reform has never shown an interest in archaic Rabbinic tradition, their arguments, Talmudic or otherwise; it’s about a ritual. As such, I don’t see why a Hot Pool of any type can’t be used for Reform conversions (I am unaware of them ever ruling that the minutiae of “old archaic” Rabbinic tradition should be upheld). It would be much cheaper.
Reform Judaism’s governing bodies dropped the requirement for immersion more than a century ago. The Pittsburgh Platform of 1885 stated: “We recognize in the Mosaic legislation a system of training the Jewish people for its mission during its [ancient] national life in Palestine, and today we accept as binding only the moral laws, and maintain only such ceremonies as elevate and sanctify our lives, but reject all such as are not adapted to the views and habits of modern civilization.” Thus did the Reform rabbinic authorities renounce – without banning – any and all requirements for ritual, including those involving mikveh. In 1977 Rabbi Walter Jacob commented that “the custom has fallen into disuse….Ritual immersion has completely ceased to be practiced for niddah [separation of spouses during menstruation] and is followed only by a small percentage within the Orthodox community” [Contemporary American Reform Responsa].
If they want to revive it, , perhaps in keeping with Reform philosophy, it’s time to invent an up to date, modern “equivalent”.
If for some reason they would like a specific set of pools for this purpose, then let it be a user-pays situation.
Reform Jews are using mikvaot today in a wide variety of alternative ways: to mark lifecycle events or a change of personal status, to celebrate joy or sanctify grief. Immersions before a bat or bar mitzvah, to mark divorce or the death of a loved one, to celebrate graduation or a trip to Israel, as gratitude after recovery from a serious illness are increasingly common. And while mikveh is traditionally practiced in privacy, some liberal mikvaot are hosting groups, including women marking the onset of menopause and men taking their sons before the High Holidays.

The Mikvah is used by Orthodox women monthly. It is most likely that it is only used for a Reform Conversion and perhaps? before a wedding. On that basis, the State should withdraw funding from all Mikvaos and make admission based on a user pays affiliation to the type of Mikva.
Would the State fund Baptism Pools as well?
The same if true of Conservative (Masorti). There are plenty of US donors who would pay for these customised pools and rules.
Separation of Religion and State needs to occur in Israel. The Chief Rabbinate no longer is respected and has managed to descend a level each time there are new appointees.
Which Mikveh does the transexual, or fluid sexual go to?
The majority of people are aligned with traditional orthodoxy and will always be and have little to do with Reform or Conservatives. These are mainly American phenomena that has been imported in small quantities into Israel.
Finally note the inequality. Male Orthodox Jews do not have the same requirements of a Mikva as a female. As such, according to many authorities they may be ritually cleaned in a swimming pool or a 4-5 minute shower. Certainly, it doesn’t have the “feel” and “preparation” of going to a Male Mikva, however, there is much that needs to be improved in the lack of Tznius in Male Mikvaos, which unfortunately isn’t being addressed by anyone it would seem.
Nobody complains about that. Perhaps feminists should argue they should have the easier rules as per men?
PS. The “diplobabble from some Shas MPs makes me cringe”.
