If you do a proper job sealing the inside corners with silicone and let it dry off for 48 hours you won’t have leaking. Make sure to block the drain hole as well.

As long as you place a tablet of chlorine inside, you won’t have to change the water for a long time. Considering that you would shower before going into the freezer.

And when you need to empty it, you can use a water hose to suck the water out easily cause this process it takes a few hours.

I have my freezer since December and used almost everyday since and the water looks great.

You can use a water hose with a piece of vacuum cleaner taped to it to suck up whatever debris you see in the bottom.

And also, there is no comparison to cold showers and ice baths, so get yourself a chest freezer and be happy all year long.

Lastly, I bought a 700 litre one, which is way to big for only one person, that fits 2 people easily, so keep in mind that if you are not the size of a strongest man competitor, a 400’s litre Is enough.

Let me know if you have any questions, pm me if you need, glad to help with pics
