Home Cold Plunge Tub Size + Capacity Calculator

Use this tool to get the exact capacity requirements for your cold plunge. Tailored to your exact scenario.

For those purchasing a cold plunge and need sizing recommendations.

Inputs for user height, number of users, budget, plunge type, and water depth preference are needed to calculate the exact tub size and water volume for comfortable, full immersion without wasting space or money. These ensure proper ergonomics and safety. Limitation: it assumes average body proportions and may not account for very tall or broad users perfectly.

Ideal Cold Plunge Tub Sizing

Recommended Tub Size

1. Length: 4 ft (48 in)
2. Width: 2.5 ft (30 in)
3. Height: 2 ft (24 in)

Capacity Calculation

• Volume in cubic feet:
  Length x Width x Height = 4 ft x 2.5 ft x 2 ft = 20 cubic feet

  20 cubic feet x 7.48 gallons/cubic foot ≈ 149.6 gallons

This tool was built on The Tool Collective's signature model, which combines AI power and human designed logic and reasoning. We hand pick the inputs and input options, and then craft a system prompt that outlines precise instruction, logic, and output criteria so the AI engine can provide reliable and specific intelligence for every tool's exact purpose. This results in decision making tools that have the speed and precision of AI models, but also layers on real expert human oversight to ensure quality and reliability of information.
