Can you use salt water in a hot tub?

The short answer is both yes and no - it simply depends on what material the hot tub and stove are made of. Seemingly identical materials can also differ in how they withstand salt water - there are stainless steels that can withstand salt water and stainless steels that do not.

The advantages of choosing a hot tub that can withstand salt water are many - if you have access to sea or sea water near the cottage or villa, you can use it as well as fresh water, it is also an advantage in places that risk being affected by water rationing due to low stormwater levels.

Our outdoor bathtubs can withstand salt water. The shape of the bathtub also affects when it comes to water consumption - a hot tub can require anything between about 800-2000 liters of water depending on size, while our smaller tub Sooty Casserole only requires 470 liters and our larger bathtub Bohemia requires 600 liters. Which makes them heat up faster, they require less wood and weigh less.
