In this step-by-step guide, we’ll discuss with you how to install a cultured marble shower base in your own bathroom.
Easy Steps on How To Install a Cultured Marble Shower Base

1. Gather Materials
Before you start, it’s crucial to ensure you have all the necessary tools and materials. Here’s a list of what you’ll need:
- Measuring tape
- Level
- Power drill
- Saw
- Adhesive
- Screws
- Silicone caulk
- Rubber gloves
- Safety glasses
- Dust mask
When purchasing materials, take measurements carefully to ensure you purchase the correct size shower base.
2. Preparation
Before you can install your cultured marble shower base, you’ll need to prepare the shower space. Here are the steps you’ll need to follow:
- Measure the shower space: Use a measuring tape to measure the dimensions of your shower space. Be sure to measure the space’s width and length and note any irregularities or obstructions affecting the installation process.
- Prepare the subfloor: The subfloor should be clean, level, and free of any debris or lose materials. Use a saw to cut any protruding wood pieces, and ensure the surface is smooth and even.
- Clean the shower space: Use a broom and dustpan to remove any debris from the shower space, and wipe down the walls with a damp cloth to remove any dust or grime.
3. Placing the Shower Base
Now that the shower space is ready, it’s time to install the shower base. Here’s how:
- Lay the shower base in position: Carefully lift it and lay it in the shower space. Ensure the base is aligned with the walls and centered in the space.
- Check for level: Use a level to check that the base is level in all directions. If the base is not level, add shims or remove material from the subfloor as necessary.
4. Securing the Shower Base
Once the shower base is in position and level, it’s time to secure it in place. Here’s how:
- Apply adhesive to the subfloor: Use a power drill to drill pilot holes. Then, apply a generous amount of adhesive to the subfloor using a trowel.
- Set the shower base in place: Carefully lower the base onto the adhesive, ensuring it is aligned with the walls and centered in the space.
- Secure the base with screws: Use a power drill to screw the base into the subfloor, following the manufacturer’s instructions for screw placement and quantity.
5. Sealing the Shower Base
To prevent water from seeping between the shower base and the subfloor, you’ll need to seal the edges of the shower base with silicone caulk. Here’s how:
- Apply silicone caulk around the base: Put on rubber gloves and safety glasses, and use a caulking gun to apply a generous amount of silicone caulk around the base’s edges.
- Smooth and even out the caulk: Use a caulk smoothing tool or your finger to smooth the caulk, ensuring it fills any gaps between the base and the walls.
- Let the caulk dry: Allow the caulk to dry according to the manufacturer’s instructions before using the shower.
6. Finishing Touches
Now that the shower base is installed and sealed, you can add the finishing touches to complete the project. Here are a few ideas:
- Install the shower walls: If you’re planning to install shower walls, follow the manufacturer’s instructions for installation.
- Install the shower fixtures: Install the showerhead, faucets, and other fixtures according to the manufacturer’s instructions.
- Add a shower door: If you’re planning to install a shower door, follow the manufacturer’s instructions for installation.
Maintenance of a Cultured Marble Shower Base

To keep your cultured marble shower base looking great for years to come, it’s important to take good care of it. Here are a few tips:
- Clean the shower base regularly with a non-abrasive cleaner and a soft cloth or sponge.
- Avoid using harsh chemicals or abrasive cleaners, which can damage the surface of the shower base.
- If you notice any cracks or chips on the shower base, repair them promptly to prevent further damage.
What Goes Behind Cultured Marble Shower Base?
Cultured marble shower bases are popular for homeowners because they are durable, beautiful, and low maintenance. These shower bases are made by mixing crushed limestone, resin, and pigments to create a smooth, non-porous surface resistant to stains and scratches.
The manufacturing process of cultured marble shower bases involves several steps. Firstly, the mold is created using a combination of wood, fiberglass, or steel. The mold is then coated with a gel coat, a resin layer that provides a smooth and glossy finish.
Next, the crushed limestone and resin mixture is poured into the mold and cured for several hours. Once the mixture has set, the shower base is removed from the mold, and any excess material is trimmed away.
The final step in the manufacturing process involves polishing the solid surface of the shower base to create a glossy finish. This is done using a series of abrasives and polishes applied to the surface in a specific order. The end result is a beautiful and durable shower base that is easy to clean and maintain.
Does the Cultured Marble Shower Base Crack Easily?
Cultured marble shower bases are made of a mixture of crushed limestone and resin and are known for their durability and resistance to cracking. However, like any material, cultured marble shower bases can crack under certain circumstances.
One of the most common reasons a cultured marble shower floor cracks is improper installation. If the custom cultured marble base is not properly supported during installation, it can flex and crack over time.
This is why it is important to have a professional install your cultured granite shower pan base, as they have the expertise and equipment to ensure it is installed correctly.
Another reason why cultured marble shower bases and marble countertops can crack is if they are subjected to excessive weight or impact. For example, dropping a heavy object on its surface could cause it to crack. Similarly, if someone were to jump or stand flat on the shower base, it could also crack.
Despite the potential for cracking, cultured marble shower bases are generally quite durable and can last for many years with proper care and maintenance. To reduce the risk of cracking, it is important to avoid placing heavy objects in the shower and jumping or standing on it.
Furthermore, it is important to follow the manufacturer’s instructions for cleaning and maintenance to ensure that the wall panels and the base remains in good condition.
What Is a Drawback of Cultured Marble Base in Shower?
Cultured marble shower bases are popular for homeowners due to their durability, beauty, and low maintenance requirements. In contrast, one drawback of using a cultured marble base in a shower is that it can be slippery when wet.
Cultured marble shower bases have smooth, non-porous surfaces that can become slippery when water or soap is present. This can create a safety hazard, especially for young children, elderly individuals, or those with mobility issues.
To mitigate the risk of slipping, it is vital to take steps to increase traction on the surface of the shower base. This can be done by using a non-slip mat or applying a non-slip coating to the surface of the shower tub surround base.
Moreover, keeping the shower base clean and free of soap scum or other debris is important, as this can further increase the risk of slipping.
While the slipperiness of a cultured marble shower base can be a drawback, it is important to remember that this is a common issue with most types of shower bases. By increasing traction and maintaining a clean surface, homeowners can enjoy the many benefits of a cultured marble shower base without sacrificing safety.
