When you’re selecting a product to cleanse 90% of your body, it pays to make an informed decision. According to the Women’s Health Magazine, the population is split 50/50 between bar soap and body wash. Bar soap sales are declining and younger generations are put off by the inconvenience and assumed uncleanliness of it. Bar soap slips out of people’s hands when wet, melts and get stuck to the wall unit, gets unusable as it nears the end of its lifespan, and is hard to travel with. While body wash is a more appealing solution for multiple users, it is likely that many body wash users would rethink their preference if their concerns were remedied. Our research focused on different household products that could solve these inconveniences. Specifically, we looked at different types of wall units at various hardware retailers that were designed to hold bar soap.

Option 1: Run of the mill ceramic wall unit
This is your generic wall unit that collects a pool of water which melts and adheres your soap to the unit. It does not solve any of the aforementioned inconveniences and the suction wears down over time/

Option 2: Metal “basket” wall unit
With a bit of innovation, this option is a sizeable improvement over the generic wall unit, as water can escape and one can avoid getting the soap stuck. However, it does not solve the usability problem as the soap nears the end of its lifespan, the slipperiness, or the mobility issue. The open design also allows smaller soap pieces to fall through.

Option 3: Travel plastic box
This travel solution is flawed for a number of reasons. First, the seal is not completely reassuring and, since there is no drainage, the soap stays messy. The case collects water in the shower and exacerbates the soggy soap problem. A successful soap holder would likely be achieved by going in a different direction.
All in all, there exists no easily accessible product on the market that can solve several of the issues that we identified with using bar soap. We propose a brand new product that can make people’s lives easier when it comes to using bar soap. The product we envision is essentially a Push-Pop with soap in it rather than candy. First, the holder serves as an excellent grip even when wet, and you simply apply the soap as you would apply a stick of deodorant. As you use the soap, you simply push it up (or twist) more to access unused soap, allowing you to use your soap just the same until it’s completely gone. And even better, if you’re going to be on the go, simply put on the cap and throw it in your bag. You’ll never have to worry about it being a wet mess and leaking all over your other items. Additionally, bar soap of any size is permitted by TSA and eliminates the hassle of mini body wash bottles that contain enough for just one shower. Since only a portion of the soap is exposed to water it will last a lot longer, thus saving money, and avoid the bacteria that grows in sitting water. Lastly, finding a place for it is simple as well. The sides of the case are magnetic, so you can slap it right on your shower handle.
