ok, fiddling about fitting, waste and feet etc. to a steel bath, pondered whether it would be worth insulating it - squirty foam?
Though I'm thinking that with a big surface area on top, and an enclosed space below it maybe isn't worth the effort?
Metal baths do go cold noticeably quicker than plastic. Foam sounds a messy hassle though. Maybe thin sheet polystyrene or glue & fibreglass. Or just stuff the space with fibreglass.

Not worth the effort. There is no appreciable energy saving, maybe a small gain in comfort.
Squirty foam won't stick to the underside of horizontal surfaces. Not even much good on vertical surfaces. Just rolls off.

I think it's worth a go, although there's a lot of heat loss from evaporation I'm sure there is quite a bit going through the walls of the bath too but less significant if you have a conventional 1st floor bathroom without cold draughts passing under the bath.
I would consider stuffing the space with one of the bagged fibreglass products, bagged to avoid any possible release of fibres to the bathroom, or rockwool. I had considered expanding foam myself but it is not closed cell so would absorb water from any leak, safer to have something easily removable if needs be.

Comfort would probably be worth it.
The bath is not yet installed, I could easily turn it over to apply the foam.

Hmm, good point.
But stuffing with the encased insulation is probably easier/cheaper anyway
Thanks

First - ensure there are no draughts due to holes around the drain pipes. If the area under the bath is at room temberature then there shouldn't be much of a problem.
There is little point in insulating just the bath, do the walls, floor and ceiling. Keep the room warm and the bath will stay warm too.
Can't beat a very long hot soak in a bath made of metal, topped up with hot water from a big cylinder, via fully lagged pipes. None of this moulded plastic crap, combi boilers and a hour to partly fill a bath with lukewarm water.
Having had both I'd say the modern plastic bath gives a better experience. Pretty they're not, but they don't keep going cold.

My B-i-L used a 60w light bulb under the bath in the winter.
Notice the word "Used".
Just the Once ??

Whilst looking at bathroom stuff, we came across system that had a heater to circulate the bath water through to keep it at the required temp
I'm thinking gunk buildup

Inefficient it may be but one of joys of an open fire we keep in case electric ever fails is the extremely hot water created by its back boiler. So hot the tap makes that smell that hot metal gives off,then a skin wrinkling soak with plenty in reserve. The modern immersion with its limited temp isn't a patch on it.
