I’m wondering what you all think about this project I have in mind and if there’s a better suggestion.
So I just got a wood fired hot tub and it’s just a soaking tub - literally a fiberglass shell in a wood cabinet with a built in stove and stove pipe that takes a few logs of wood to heat the water up. Due to the size of the stove, it can only ever get so hot, about 40C / 104F.
My partner loves the heat, but I fuckin love me some bubbles. I wish I could do hydrotherapy in this thing but that’s too much.
So for bubbles, I’m thinking I take a blower like this using a standard outlet:
Then I get some sort of high heat silicone hose that is 2" OD to fit this specific blower. I’m not sure where to find this and have it be OK for a human to become soup in - any suggestions?
I’ll connect that hose to the valve check and then from the valve check to… A wood slice? Something like this:
Why a wood slice? Well, I can just cut up wood in various ways to see what works best - large or small holes bored into it, different positions, number of holes… I would need to essentially create tunnels from where the hose attached to the wood.
I’m also thinking wood because I can shape, sand, and size it to fit the bottom of the fiberglass hot tub, and I don’t think this will damage the fiberglass. My thinking is that fiberglass and wood have been used together on boats for decades and they withstand pounding waves so it should be alright?
Here’s where the slice of wood would go:
I’m also not sure how to get the hose to attach to wood. Any ideas on that?
Also open to any other suggestions if there’s a better overall solution someone has.

You can usually find copper pipes already bent into nearly a circle at the hardware store. My idea would be to use one one of them since you can then use premade fittings to attach a hose.
Instead of making a perfect ring out of copper you could always make a nearly closed ring with one side attached to the hose and the other side just blocked off. I think that’d be easier

Hmm interesting idea. Do you think the copper would damage the fiberglass? Maybe I could line the bottom of the copper tube with something like high heat silicone to protect it?
Funnily enough I did check out aquarium supplies too, but I don’t think I went to hyper specialized stores yet that are for super large aquariums. Those might be too fine of bubble though, turning us into a seltzer.
Thanks for the suggestion! I’m going to explore it more.

I think you’d definitely want to use some type of elastic-y epoxy to keep the ring in place. I think people would naturally kick it and prod it with their feet without realizing they’re doing it.
Yeah I was gonna recommend like a pond air ring diffuser but you’d definitely feel like a fish in a bait bucket. Maybe you could make your own with less holes since there’s a lot of diy YouTube guides on how to make those.
