Before you even think about mixing mortar, careful planning and prep are critical. This will ensure a smooth and successful shluter shower pan installation.

Measure Your Space

The first step is carefully measuring the dimensions of your shower area. This includes the width, depth, and any potential obstructions like pipes or corners. Knowing these measurements is crucial for selecting the correct size Schluter shower pan. This is important because you want to make sure you're going to be working on the right shower area.

Choose the Right Schluter Shower Pan Kit

Once you have your measurements, it's time to select the appropriate Schluter shower pan kit. Schluter offers various sizes and shapes, including square, rectangular, and neo-angle pans. They also have options with different drain placements. Consider your shower layout, personal preferences, and the placement of existing plumbing when making your selection. Don't forget to order the correct drain assembly for your pan and plumbing setup.

Gather Your Materials and Tools

Having all your materials and tools readily available will make the installation process run much more smoothly. Here's a checklist to get you started:

  • Schluter shower pan kit (includes pan, drain, and sealing components)
  • Thin-set mortar (Schluter All-Set is recommended)
  • Notched trowel (size specified by Schluter for your pan)
  • Level
  • Measuring tape
  • Utility knife
  • Mixing bucket
  • Drill with mixing paddle
  • Clean sponges
  • Water
  • Gloves
  • Safety glasses
  • Schluter Kerdi-Band
  • Schluter Kerdi-Kereck pre-formed corners
  • Tile of your choice
  • Grout
  • Grout float

Inspect Your Subfloor

The subfloor needs to be clean, level, and structurally sound. Any imperfections or irregularities in the subfloor could compromise the integrity of your shower pan. Use a level to check for any dips or high spots. Fill any low spots with self-leveling underlayment, and repair any damaged areas before proceeding. This also gives you an opportunity to make sure your shower area is prepared to be waterproofed.

Now come the fun part! Installing the shluter shower pan itself. Follow these steps closely for a watertight installation.

Dry-Fit the Shower Pan

Before applying any mortar, dry-fit the shower pan to ensure it fits properly and that the drain aligns correctly with your plumbing. This is also a good time to double-check your measurements and identify any potential issues before committing to the installation. Make sure you can access the drain assembly.

Mix the Thin-Set Mortar

Following the manufacturer's instructions, mix the thin-set mortar to a smooth, creamy consistency. Be sure to use the correct water-to-mortar ratio to achieve optimal bonding. Again, Schluter All-Set is highly recommended for use with their systems.

Apply the Mortar Bed

Using the notched trowel specified by Schluter for your pan, apply a consistent layer of thin-set mortar to the subfloor where the shower pan will be placed. The mortar bed should be thick enough to provide full support for the pan but not so thick that it creates excessive gaps.

Embed the Shower Pan

Carefully position the shower pan onto the mortar bed, pressing down firmly to ensure full contact with the mortar. Use a level to check that the pan is perfectly level in all directions. If necessary, gently tap the pan with a rubber mallet to make any adjustments.

Allow the Mortar to Cure

Let the mortar cure according to the manufacturer's instructions. This typically takes 24-48 hours. Avoid walking on or disturbing the shower pan during the curing process.

A properly installed drain assembly is vital for preventing leaks. This is another important part of shluter shower pan installation.

Install the Drain Body

The Schluter shower drain assembly typically consists of two parts: the drain body and the drain grate. First, thread the drain body into the drain outlet on the shower pan. Make sure it's snug but not overtightened.

Connect the Drain to Your Plumbing

Next, connect the drain body to your existing plumbing using the appropriate fittings and sealant. Ensure all connections are watertight to prevent leaks. Consult a plumber if you're unsure about this step.

Setting the Drain Height

Some Schluter systems allow for height adjustment of the drain flange. Follow the instructions to set the drain so it's flush, or slightly below, the finished tile surface. This is critical for proper drainage and a professional look.

The Schluter Kerdi system extends beyond the shower pan. Proper waterproofing of the surrounding walls is equally vital.

Apply Kerdi-Band to the Wall-Pan Joint

Schluter Kerdi-Band is a flexible, waterproof membrane used to seal the joint between the shower pan and the walls. Cut the Kerdi-Band to the appropriate length and apply a thin layer of thin-set mortar to the wall and the shower pan flange. Press the Kerdi-Band firmly into the mortar, ensuring full contact and eliminating any air pockets.

Seal Corners with Kerdi-Kereck

Use Schluter Kerdi-Kereck pre-formed corners to seal any corners where the Kerdi-Band meets. Apply thin-set mortar to the corners and press the Kerdi-Kereck firmly into place.

Apply Kerdi Membrane to the Walls

Apply the Kerdi membrane to the rest of the shower walls, overlapping the Kerdi-Band by at least 2 inches. Use thin-set mortar to adhere the Kerdi membrane to the walls, ensuring full coverage and eliminating any air pockets. Make sure you apply thin-set mortar on the sides that is meant to be mortared on.

With the shower pan and walls all waterproofed, it's time to start tiling.

Plan Your Layout

Before applying any tile, plan your layout to ensure a balanced and aesthetically pleasing design. Consider the size of your tiles and the placement of any decorative elements.

Apply Thin-Set Mortar

Using a notched trowel, apply thin-set mortar to the waterproofed surface, working in small sections at a time.

Set the Tiles

Press the tiles firmly into the mortar, using spacers to maintain consistent grout lines. Use a level to ensure the tiles are perfectly aligned.

Cut Tiles as Needed

Use a wet saw or tile nippers to cut tiles to fit around the drain, corners, and other obstacles.

Allow the Mortar to Cure

Let the mortar cure according to the manufacturer's instructions before proceeding to the next step.

Grouting fills the gaps between tiles, providing a waterproof seal and enhancing the overall appearance of your shower.

Remove Spacers

Remove all spacers from between the tiles before applying the grout.

Mix the Grout

Mix the grout according to the manufacturer's instructions.

Apply the Grout

Using a grout float, apply the grout diagonally across the tiles, forcing it into the grout lines.

Remove Excess Grout

Use a damp sponge to remove any excess grout from the tile surfaces, rinsing the sponge frequently.

Allow the Grout to Cure

Let the grout cure according to the manufacturer's instructions.

Seal the Grout

Once the grout is fully cured, apply a grout sealer to protect it from stains and moisture.
