A soap pump is a canister used to keep liquid soap in. A pump or switch is commonly found on the bottom of the canister making soap come out when pressed.
If you're looking to pick one of these up, they can be an excellent option to store soap in. They can wind up being more cost effective since you can control the amount of soap that you end up using. You can push it once, or for half a pump or two pumps, it's totally up to you.
Now when you're looking to pick up a soap pump, you're going to find them come in all different types of designs and sizes as well. You'll find some that you can attach to your wall and you'll find those that you just place on your sink counter. You will also notice that they are often paired up with a soap dish as well as a trash bin as it is expected you buy all of these at once if you're looking to have your bathroom match up.
You're going to want to consider the style of the soap pump that you get though. If you're going for a more regal look, get a soap pump that reflects that. There are pumps that are futuristic looking and see through too, so you may want to consider that if you want something more modern. One last thing to consider is the weight of the pump, do you want something light weight or heavy and solid?
A soap pump may just be what you need in order to give your washroom those final touches. Make sure you match it to your trash bin though. If you have any kids in the house, they may also be more prone to washing their hands if you have one of these in the house.
