Making a Concrete Bath Tub Part 2- Mold Removal and Finishing 

I agree, way to much mass. In winter you would need an underfloor heating system in this just to make it usable. Cast iron tubs are bad enough for turning hot water cold, but solid concrete is just too much.

Any good self respecting bathroom is a private get away with in-floor and in-wall hydronics, it's own dedicated instantaneous tankless condensing boiler, heated towel bars...Ipe wood seating and flooring, infra-red heat lamps, steam generators, fully tiled, glass block natural light...glass surrounds over an inch thick, a bidet, a sauna, a door leading to private outdoor jacuzzi / tiki / koi pond garden - of COURSE, this tub has thermal mass = beneficial - once heated, it STAYS heated. Maybe it's just me.

Hmmm point

Please tell me if its possible to overlay concrete on fiberglass? Kinda ...like how they do those counter tops.i cant find any videos on it ..if u can give any advice i would really appreciate..thanks

Putting radiant floor heat in concrete, wouldn't keep up with the rate of cooling. Especially, in a basement, where it would be under the frost line. I certainly wouldn't consider putting all that weight over wood framing. I would treat it like a brick fireplace, as far as support. I like the idea of displacing the bulk of concrete with foam insulating layer. That would serve two purposes. Heat retention, and weight reduction.

Shouldn't even need to happen. If they had enough brains to use some type of form oil or sealant.
