Safe way to keep bath water warm?


I have a condition that pops up every now and then and one of the remedies is to take a salt water bath. I was thinking of doing this regularly just to prevent it from coming up in the first place, that and it's overall good for the body once and a while.

The issue I face is the water does not stay hot long enough. Rather then keep running more hot water, I was thinking, it would be more efficient to somehow keep the water warm with some kind of device.

Is there such device I can buy made for this? I'm thinking, some kind of pump with two hoses or something, and just circulate/heat the water, and plugs into a GFCI outlet. Probably not hard to make, but rather buy if one exists.

Is there a way for you to access the outside walls of the tub? If you spray foam insulation all the way around it and underneath, it'll stay hot a lot longer.

this seems to work for some



If you can set the thermostat low enough, maybe something like this and a low gpm pump.

When I redo our bath I'm thinking of wrapping the new tub in pex & connect it to a sm water heater
Or existing WH

I think they make portable spa units that hang on the side of a tub

I was actually thinking something like that may work. I'm surprised there is no actual device made for this though, but so far I'm not finding anything.

Really one thing that I should have done before the contractor installed the bath was to put some pex tubing coiled up under it, for future radiant heat. That could be cool to have.

there is this type of heater unit but you would still need a pump.

then there is this which apears to be both pump and heater:

Anyone worried about Legionnaire's Disease and other diseases in such a situation?

Wikipedia says warm water is the ideal breeding ground for Legionella.

Happen to have forced air heat? Just add another line under it.
