Difference Between Shower Pan, Shower Base, and Shower Curb

Shower Base

A shower structure in the bathroom comprises three different aspects on the ground: Shower pan, base, and curb. Let us understand each of these components to build a better structure. The shower base is the lowest substructure underneath the shower floor. It is not visible from the top but acts as a strong foundation in the whole built-up.

A shower pan is the floor on which you stand while taking the shower. This layer comes after the base and is visible from the outside.

A shower curb is a raised barrier separating the shower from the rest of the bathroom. This ensures the flow of water remains within the shower area. It keeps the bathroom area clean to dry yourself and change clothes after the shower. Imagine water running everywhere after you have a shower! What a mess it would create. The shower Curb is the element that will avoid any such kind of mess.

We will understand in detail which materials are suitable for building such a structure and what is the ideal shower curb height.

Ideal Height and Material Used

Ideal Height and Material Used

Considering the safety and effectiveness of different levels, a shower curb height can range from a minimum of 2 inches to a maximum of 9 inches. As we saw earlier, a shower curb holds the water within a boundary and keeps the exterior area dry. If we have an extremely low shower curb, it will not be able to serve its purpose and spill the water all over the place.

On the other hand, if it is too high, an individual can trip and fall on the floor, resulting in a major injury.

There is no ideal material for building a shower curb. It depends on the interior of your bathroom. Select a material that complements the interior and color of your shower area. Generally, the shower curb can be made of wood, cement, stone, caulk, cement blocks, pre-formed polystyrene pieces, or high-density plastic components. All of these materials can be customized in the shape and color you want.

When using wood as a shower curb, make sure it is waterproofed. Pressure-treated lumber wood is also a great option for shower curbs. Using engineered stones as the shower curb will ensure that the surface will not absorb water and corrode. Stone will give a shiny finish and simply dry off with a simple wipe. Some of the plastic shower curbs come in pre-made form. They simply need to be adjusted and affixed to the surface.

How to Build a Shower Curb?

After knowing about the ideal shower curb height and materials that can be used, it’s time to understand the procedure of making a shower curb. Decide the shower curb height before beginning this process.

Step1: Create the Foundation

Select the curb material depending on the flooring you have. Use a wooden shower curb with wooden flooring. Let us assume you are working with wooden flooring. Put aside three wooden boards of 2*4 size. Now, create a structure by placing these pieces on each other to form a curb. Place the three wooden pieces in a way that the edges of all three wooden boards align with each other.

Affix them to the shower base using a screw and make sure they stick tightly with each other too. You can similarly cut any other material in such shape according to your shower area length and affix it to the floor.


  • Be mindful of the curb height
  • Don’t use lumber on the concrete floor, and it will swell.
  • Consider durability while deciding the size
  • Use non-corrosive screws, if possible.

Step2: Place the Waterproof Pan Liner

The next step is to buy a waterproof pan liner for protection of the surface. It is suitable to buy a flexible structure that is easier to fold according to the shower base. Spread the liner in a way that it covers the whole wooden curb structure. Also, extend the liner to cover the bathroom area fully. Take proper measurements while buying the liner. If you are not sure, there is no harm in buying a larger and flexible liner. In the case of a rigid liner, put it in the sun for some time. It will help in making the material a little loose to fit the curb.

Step3: Removing the Liner from The Drain Hole Area

Once you have placed the liner all over the curb and shower area, it’s time to cut the drain hole. Remember, any cuts made in the liner are permanent. If you mess up in this step, it will cost you more. With a utility knife and precision, cut the drain hole. Feel the hole and target the center of the hole. Once you pierce through it, estimate the round cut and remove the liner with the help of a knife.

Step4: Align the Liner to the Bathroom Base

Arrange the liner with the help of tape and nails by raising the edges to connect with the wall. Affix the liner to the surface in a way that there is no space for water to escape the surface and flow outside the curb. You can also use dam corners to cover the interior part of the liner. Such dams are pre-formed with specific shapes, making it easier for them to adjust and fix.

Step5: Lay Down the Lath Layer

The next step is to cover the shower curb height with a metal lath. To make the foundation stronger, you will then cover the lath with a mortar mixture. Find a metal lath of suitable size and affix it on the curb. Affix the lath by using nails on a wooden surface. If you are building a concrete curb, the lath will stay in place without using nails. You will easily be able to buy metal lath from online stores.

Step6: Mud it up

Once the lath is affixed, it’s time to cover it with the mortar mix for its final strength. If you don’t know how to make a mortar, buy a pre-made mixture from the store and mix water. Apply the mortar on every side with utmost care and build a thickness that protects the curb. Once you are done applying, even out the surface by removing access material on any sides.
