How to Make a Finished Concrete Shower Floor

A concrete shower floor is a durable and stylish option for your bathroom. It's also a DIY project that can save you money. Here's a step-by-step guide on how to create a finished concrete shower floor:

1. Prepare the Subfloor

  • Clean and Level: Remove any debris, dirt, or old flooring from the subfloor. Ensure the subfloor is level using a level and a straightedge. If necessary, use a leveling compound to address any uneven areas.
  • Install a Waterproof Membrane: This is crucial for preventing water damage. Options include a pre-sloped shower pan kit, a rubber membrane, or a liquid membrane.
  • Create a Slope: The shower floor should slope toward the drain at a minimum of 1/4-inch per foot. Use a level and a straightedge to check the slope. You can adjust the slope by adding or removing mortar under the membrane.
  • Install a Drain: Choose a drain that fits your needs and install it according to the manufacturer's instructions. Ensure the drain is level with the subfloor.

2. Prepare the Concrete

  • Mix the Concrete: Follow the manufacturer's instructions to mix the concrete. Use a concrete mixer for larger projects.
  • Add Additives: Consider adding a waterproofing admixture and a color pigment to the concrete mix. These additives enhance the durability and aesthetics of the finished floor.

3. Pouring the Concrete

  • Spread the Concrete: Start at the highest point of the slope and spread the concrete towards the drain. Use a trowel or a screed to level the concrete.
  • Compact the Concrete: Use a concrete vibrator to remove air pockets and ensure a solid and durable floor.
  • Finish the Surface: Depending on your desired finish, you can use a trowel, a float, or a broom to create a smooth, textured, or brushed surface.

4. Curing the Concrete

  • Moist Curing: Cover the concrete with plastic sheeting to maintain moisture and prevent cracking. This process can last for several days.
  • Allow Curing Time: Allow the concrete to cure completely before applying any sealant or tile. This can take several weeks, depending on the temperature and humidity.

5. Finishing Touches

  • Seal the Concrete: Apply a sealant to protect the concrete from stains and water damage.
  • Add Tile: If desired, you can install tile over the concrete floor.
  • Grout: If using tile, grout the spaces between the tiles to create a watertight seal.

Tips for a Successful Concrete Shower Floor:

  • Plan Ahead: Carefully measure and plan the layout of the shower before starting.
  • Use Quality Materials: Invest in high-quality concrete and additives for a durable and long-lasting floor.
  • Work in Stages: Pouring concrete in sections helps you maintain a consistent slope and prevent cracking.
  • Pay Attention to Detail: Ensure the drain is properly installed, and the slope is accurate for optimal drainage.
  • Follow Safety Precautions: Wear safety glasses, gloves, and a dust mask when working with concrete.

With careful planning and attention to detail, you can create a stunning and functional concrete shower floor.
