How to Make a Bar of Soap Last Twice as Long

If a handmade bar disappears in two weeks, it's almost never the soap. It's where you're keeping it. Here's what actually changes how long a bar lasts, roughly in order of impact.

1. Let it drain

This is the whole ballgame. A bar sitting in a puddle absorbs water continuously and turns to mush from the bottom up. A bar that dries fully between uses can last twice as long, sometimes longer.

Use a dish with slats or ridges that lifts the bar clear of standing water. A soap saver pad works. So does a folded washcloth. The cheapest option is a plastic dish with drainage holes, and it will do more for your soap budget than anything else on this list.

2. Keep it out of the direct spray

If your soap sits where the shower hits it, it's being slowly washed away while you stand there. Move it to a corner, a shelf outside the spray line, or a shower caddy on the opposite wall.

3. Cut it in half

Counterintuitive, but effective. Use half and store the other half somewhere dry. The unused half stays hard and doesn't degrade, and a smaller bar spends less surface area sitting wet. Handmade soap also continues to cure in storage, becoming harder and longer-lasting the longer it sits.

A serrated knife cuts a bar cleanly. Do it when the soap is at room temperature rather than cold.

4. Use a washcloth or pouf

Rubbing a bar directly on skin uses far more soap than you need. Work up lather on a cloth, pouf, or your hands, then apply that. You'll get more coverage from less bar, and better lather too.

5. Don't buy ahead of your storage

Soap improves with age when stored properly. Wrapped in paper or left uncovered in a dry drawer, a cured bar will keep for a year or more and gets harder over time. Sealed in plastic in a humid bathroom, it does the opposite.

If you buy several bars, keep one in the shower and the rest somewhere dry. A linen closet works well, and the bars will lightly scent it in the meantime.

Why tallow bars have an advantage here

Hardness is mostly determined by the fats used. Bars high in olive oil are soft and dissolve quickly. Bars made with tallow are dense and hard, which is why tallow was the traditional choice long before it became a talking point. Our Midnight Tide and Rose Bud bars are both made this way.

That density is also why a tallow bar rewards good storage more than a soft bar does. Keep it dry and it will outlast most of what's on a shop shelf.

The one thing that won't help

Storing soap in the fridge, freezing it, or microwaving it are all suggestions you'll find online. None of them meaningfully extend a bar's life, and freezing can cause it to sweat when it warms back up. Drainage is the answer, and it's a $3 fix.

If you'd rather not deal with a bar at all, our Noble liquid tallow soap sidesteps the whole problem. Otherwise, browse the full soap collection — they're dense by design, and they'll go a long way if you keep them out of the water.

Curious what makes a tallow bar different from a drugstore one in the first place? We cover that in tallow soap vs. regular bar soap.
