The best sauna buckets and ladles

The bucket and ladle is the one sauna accessory that is genuinely required rather than nice to have. Without it you have a hot room; with it you have a sauna, because throwing water on the stones — löyly — is the thing that makes the difference between the two.

It is also the accessory most likely to be replaced within three years, and for a reason nobody mentions at the point of sale: a wooden bucket that holds water in a room that goes from ambient to 190 °F and back every day is being asked to do something wood is not naturally good at.

Why cedar buckets fail, and what fixes it

The mechanism is straightforward once you see it. Wood swells when wet and shrinks when dry. A bucket that is filled, heated, emptied and dried repeatedly is being cycled through that expansion continuously, and the staves work against each other until a joint opens. That is why an old sauna bucket leaks from a seam rather than splitting down the middle.

There are exactly two fixes. The first is discipline: empty the bucket after every session and let it dry evenly. A bucket left half full for a fortnight is a bucket that has swollen on one side and dried on the other. The second is a liner — a removable plastic insert that means the cedar never contacts the water at all.

The liner is a compromise on the traditional object and it works. If you are honest with yourself about whether you will empty and dry a bucket after every single session, it is straightforwardly the better buy, and it is the reason our lined pick sits second on this list rather than sixth.

How we picked

1. 1Published bucket capacity in liters or gallons. Astonishingly, several bucket listings do not state one. A bucket whose volume is unpublished is a strange product.
2. 2Published ladle volume. Rarer still and more useful than it sounds — bucket capacity divided by ladle capacity is the number of throws per fill, which is the only genuinely practical figure in this category.
3. 3Whether a liner is included. The single strongest predictor of how long the bucket lasts.
4. 4Single-piece ladle construction. A ladle hewn from one piece has no joint to loosen in heat. A glued handle is the first thing to go.
5. 5Named wood. Canadian red cedar throughout, or cedar-effect on something else. The listings that name the species and the origin are the ones being specific.

Sizing: throws per fill

Here is the arithmetic the category never does for you, using the two products in this survey that publish both figures.

A caveat on the throws figure: it assumes you fill the ladle. In practice most people throw a partial ladle and go more often, so treat 40 as a ceiling. For a solo 20-minute session you will use a fraction of either bucket.

What to actually throw

Plain water, and there is a reason to be careful about the alternatives.

• Water alone is the tradition and the default. It is what the stones are designed for and what your heater's warranty assumes.
• Essential oils go in the water, never on the stones. Neat oil on a 400 °F stone can scorch and, in the wrong concentration, catch. Diluted heavily in the bucket is the correct method — a few drops in several liters.
• Check your heater's manual before adding anything. Some manufacturers void warranties over additives, and the ones that do say so explicitly.
• Do not throw water on an infrared cabin's panels. This applies to a large share of the people reading this page. Infrared cabins have no stones and no water-throwing capability, and the panels are electrical. Our infrared versus traditional comparison covers the distinction properly.
• Use the ladle, not the bucket. Throwing the whole bucket cools the stones sharply and can crack them. It also produces a wall of steam that will hurt.

How the stones are stacked matters as much as what you throw — a loosely stacked heater takes water far better than a tightly packed one. That is covered in the sauna stones guide.

Care, briefly

Four habits, and they are the whole of it. Empty it after every session. Store it on its side or upside down so it drains and dries evenly. Keep it out of the direct heat path above the stove, where it will dry too fast on one side and crack. And do not scrub it with detergent — rinse it, because cedar's natural oils are doing more for you than soap would.

Do that and an unlined cedar bucket will last many years. Skip it and the liner becomes the difference between a bucket you own and a bucket you replace.

The one we would skip

The bundled set with a thermometer — if you already own a thermometer, which after a first sauna season most people do.

The set itself is good, and coming from a company that builds saunas rather than assembles catalog items is worth something. But a bundled gauge is usually a basic one, and if there is already a proper thermometer and hygrometer on your wall you are paying for a third piece you will put in a drawer. Buy the bucket you want and keep the gauge you have — our thermometer roundup covers what a good one looks like.
