If you’re building a DIY cold plunge and want it done right the first time, these plans walk you through a clean, reliable plumbing setup that actually works in the real world—no overcomplicated nonsense, no fragile shortcuts.

These are the exact layouts I use myself, tested under real cold plunge conditions with icy water temps, inflatable tubs, stock tanks, and budget-friendly chillers.

Price: $0.00

Yes—free. Just grab them through checkout so I know where to send them.

🧠 Why These Plans Work

I’ve built multiple cold plunges—some great, some… learning experiences 😅

These layouts eliminate the common problems:

• ❌ Leaks from bad transitions

• ❌ Pump strain and poor circulation

• ❌ Over-complicated builds that never stay running

This setup keeps water moving smoothly, stays easy to service, and doesn’t require constant tinkering.

🛠️ Who These Plans Are For

✔ DIY builders

✔ Inflatable tub owners

✔ Stock tank plunge setups

✔ First-timers who want clarity

✔ Experienced builders who want a cleaner system

If you’re the kind of person who values doing it once and doing it right, these are for you.

📦 What’s Not Included (On Purpose)

These are plumbing plans, not a full build kit.

You’ll still choose:

• Your tub

• Your chiller

• Your pump & filters

That’s intentional—it keeps the plans flexible and budget-friendly.

Inside the PDFs, I also include recommended parts and trusted suppliers I personally use. Some of those links are affiliate links, which means it doesn’t cost you anything extra—but if you choose to purchase through them, I earn a small commission.

That support goes a long way in helping me keep resources like this free, continue testing gear, and keep the YouTube channel running with real-world builds, updates, and improvements—not sponsored fluff. It’s completely optional, but genuinely appreciated.
