Hello Everyone, Has anyone built a Hot tub with ICF. If you have, do you locate the perimeter pipes in the middle of the ICF or outside of it? And if you locate them inside, do you put foam around the pipes ? Where within the ICF do you locate the pipes ? As outside as possible to be able to access them in case of trouble (just need to dig some foam?) Finally, I have exhausted my Google search skills for building an ICF Hot Tub ... do you have any plans/references ? I will for sure post a you tube video if I succeed :) Thank you.

I have done a 9000 gallon pool in my basement. I used Hot Tube fittings around the top and recessed them into the foam and concrete. The hot tube fittings have removable centers with an outside housing.

I did a mono pour of the walls and floors and had to pour the floor and then quickly put plywood down to hole the concrete back to fill the walls.

There is extruded Poly on the floor. Note: I have not put a liner or finished the walls. Still finishing the house.

There is pictures in this link. Good Luck

Nice project all together! Massive. What are those Hot Tube Fittings you are mentioning ?

This is the brand and type of bodies I used. I again am not a pool or spa builder and have not filled the pool with water.

I didn't use the air inputs and most that have air inputs have them covered and you have to break out a plug to get them to flow air.
I got to using these through month of searching....good luck but do your own research

I recently did a DIY spa with single side ICF forms (along with a swimming pool and patio/gazebo project). I did most of the spa pipes on the outside of the ICF, added foam, then Hardie/concrete board and tile for the outside finish. There are probably easier ways to do a spa, but I'm happy with the results.

Here are a few pics of my spa construction process.
