How to Install a Loose Pebble Shower Floor

A loose pebble shower floor is a beautiful and natural option that can add a touch of luxury and aesthetic appeal to your bathroom. Its textured surface provides a massage-like experience while offering excellent drainage. Installing a loose pebble shower floor may seem like a challenging task, but with the right materials and a step-by-step guide, it can be a rewarding DIY project. Let’s dive into the process and get started!

Materials Needed:

  • Levelling compound
  • Thin-set mortar
  • Waterproof membrane
  • Notched trowel
  • Grout float
  • Sponge
  • Grout sealer
  • Pebbles
  • Tile spacers
  • Silicone caulk

Step 1: Prepare the Subfloor

Before installing the loose pebble shower floor, it is crucial to ensure that the subfloor is properly prepared. Start by removing any existing flooring material and thoroughly clean the surface. Check for any cracks or uneven areas, as these need to be addressed before moving forward. Use a levelling compound to smoothen out any imperfections on the subfloor, allowing for a flat and stable base.

Step 2: Apply the Waterproof Membrane

To protect the underlying structure from water damage, it’s important to apply a waterproof membrane to the subfloor. Follow the manufacturer’s instructions to apply the membrane evenly over the surface of the subfloor, ensuring complete coverage. This process typically involves using a paint roller or a trowel. Allow the membrane to cure as per instructions before proceeding.

Step 3: Mix and Spread the Thin-Set Mortar

Start by mixing the thin-set mortar according to the manufacturer’s instructions. Consistency is key here; aim for a spreadable yet firm texture. Using a notched trowel, spread the mortar evenly on the prepared subfloor. Focus on a small area at a time to prevent the mortar from drying out before placing the pebbles. Create grooves on the mortar’s surface using the notched side of the trowel. This will improve the adhesion of the pebbles.

Step 4: Place the Pebbles

Take the pebbles and carefully press them into the thin-set mortar, ensuring that they are flat and level with the surrounding surface. Maintain a consistent gap between the pebbles using tile spacers for a clean and uniform appearance. Work in small sections, spreading the mortar and placing the pebbles, until the entire shower floor is completed. Allow the thin-set mortar to cure for the recommended time by the manufacturer.

Step 5: Apply Grout and Seal the Finish

Once the thin-set mortar has fully cured, it’s time to apply grout. Choose a grout color that complements your pebble selection. Using a grout float, apply the grout mixture to the surface, working it into the gaps between the pebbles. Remove any excess grout using a damp sponge, being careful not to dislodge the pebbles. Let the grout dry according to the manufacturer’s instructions, and then apply a grout sealer to protect and preserve the finish.

Congratulations! You have successfully installed a loose pebble shower floor. Remember to regularly clean and maintain the pebbles to keep them looking their best over time. Enjoy the natural and spa-like feel your new shower floor brings to your bathroom!
