DIY Shower Pan Concrete Mix

The ideal DIY mortar mixture for a shower pan includes a mortar mixture, sand, and Portland cement. For your shower, this particular mixture forms a sturdy water-resistant barrier.

You can purchase a bag of premixed concrete or prepare your own. Making concrete is a basic process. It consists primarily of Portland cement, sand, and aggregate gravel blended with water.

The strength and functionality of the concrete can be changed by varying the amounts of each constituent. Although you can mix in certain additions, many individuals simply use it as is.

You simply need one part Portland cement and five parts fine sand to make your concrete shower pan. You need four quarts of water to mix each 80-pound bag of concrete. 

Measure the cement and sand first, separately. Then use a shovel, trowel, or hoe to thoroughly combine the dry components in a wheelbarrow or cement mixer. Water should then be added and thoroughly mixed to create the finished concrete.

While you might be able to save a little money by making your shower pan concrete, it does require extra work. Each item must be purchased separately, measured, and mixed by hand. An already-mixed Quikrete bag takes care of everything for you.

If you don't require a specific mix or a large quantity of concrete, we suggest purchasing Quikrete.

Note that while you want the mixture to be dry, it will have some moisture content.
