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.
