How long does a bar soap can last is an interesting question. The experiment shown here will give you an idea about the same. There are factors that can influence the result and we will explore that.

Let me give a very quick answer to the question, then we will drill into the details.

A normal bath can use somewhere around 4 to 5 grams of soap. So, typical bar soap can last up to 4 to5 weeks for a single bath per day.

However, there are many factors that can affect this.

Let us look into it further:

The duration of a bar soap definitely is based on its usage and it can differ from situations to situations.

I have done an experiment with a bath and following is the result:

Soap weight before the bath: 51 g

Soap weight after the bath: 46 g

So it is on average 5 grams.

Soap Weight Before the Bathe:

Soap Weight After the Bathe:

As common sense says, there are many factors that can influence the soap consumption per usage.

Those are:

Brand of the Soap – some soaps are harder and thus less dissolving

Initial Weight of the Soap

Age of the soap – if the soap is moist, it could dissolve easily

Duration of the usage.

Some people do not need much lather to bathe or wash, just a little they are fine, while little bit of lather doesn’t cut with it some, and you may come across people that say their bar soap last for at least a year, perhaps those are people that use bar soap let’s say only once in a month, but ideally bar soap should last for at least a month if you apply a little effort to prevent wasting of the soap.

And because you see a need to make your soap last longer, it does not mean you should not use the bar soap to your optimum satisfaction. It may shock you to know that the reasons your bar soap is not lasting long as it ought to, could be due to avoidable simple mistakes.

For instance, water may waste away the soap if you store it in a wet place especially if you store it in the middle of the shower or leaving it in a case that doesn’t drain well. The water in the case will cause the bar soap to depreciate real fast yes depreciate!

The water won’t just waste away the bar soap but also reduce the quality and efficacy of the bar soap to ensure a soothing exfoliating bath, in this kind of situation you may not have any choice than to cut the life of the bar soap short yourself by throwing it away when all the good it has to offer has been drain away by the water. So to avoid this, put your bar soap in a dry container and in a dry place always, or better still, put it out to air dry it, after every use.

Also if you want your soap to last longer than the usual length of time desist from using it with the hand because, it takes longer time before the soap lather when used with the hand so it is advisable to use wash cloth or loofah instead of hand.

Slightly rubbing soap on the wash cloth is enough to produce the necessary lather to wash the dirt of your body or clean your hands.

All these reasons that makes bar soap not to last longer are just minor things we do overlook or see as insignificant, but they are actually significant to make the soap last longer even up to six weeks, yes it sounds unlikely, but is true your bar of soap can last up to six weeks if you are able to use it well, and of course, you can if you begin to take cognizance of these few tips to make bar soap last longer

Tips to make bar of soap last longer

Store Your Soap In The Most Suitable Soap Dish

Don’t just get a soap dish that will fit the soap size or that has an elegant design and fantastic finish without proper drainage. A soap dish with nice drainage will drain out moisture from the soap to prevent soggy soap and of course, ensure long use of soap.

Place Soap In Moisture Free Area

Water is the main reason why soap wastes away so ensure to place it in areas free of moisture.

Use Either Of Wash Cloth Or Loofah

Your soap will hardly last for 2 weeks if you use it with the hand, but you are in for a longer use of bar soap if you can make use of the wash cloth though, some people prefer the use of hand, however, using wash cloth is a better choice for the bar of soap to last longer.

The hand does not possess the capacity to retain lather compared to wash cloth that retain lather efficiently after rub it with the soap to ensure a soothing bath without hassle or stress is like using a machine, so why using hand when you have the luxurious wash cloth to ensure proper bath, the ball is in your court, if you need to use your bar soap up to a month then use your bar soap with either of wash cloth or loofah depending on personal preference.

Let The Bar Soap Air Dry

Your bar soap will likely not air dry completely if you have multiple people using it perhaps to save cost, but if you do the math you will found out that the cost will amount to the same value or more cost effective depending on price of the soap.

So everyone should have his or her personal bar soap, it will go a long way in making the soap last longer also ensure that the soap air dry completely, hence, make it stronger for one person to use it for over a month instead of the usual one or two weeks. And don’t forget to take it out after every use to air dry.

Favorite Type Of Shower

Hot water dissolves soap faster compared to cold shower, and it does not lather quickly due to the heat, so if you prefer hot water to cold water then your chance of conserving bar soap has reduced by certain percentage.

Conclusion

A bar soap can last up to one month if properly used, but, to ensure longer use of your bar soap from this time on make sure you store it in a drainage soap dish also make sure you do not store it in an area where water can make contact with it, other factors to consider include, allowing the soap to air dry completely, use wash cloth instead of hand with the soap, and try use cold water, but if you prefer hot water know that hot water dissolves bar soap faster compared to cold water.
