Can You Install an Under-Tile Flush Plate After the Tiles Are Already Installed?

We often receive the same question from customers:
“Can I install your flush plate even if my tiles are already finished?”

The short answer: Yes, you can.

While it’s not the ideal situation, it’s absolutely possible and it’s done quite commonly. Many installers face the need to replace or newly install a flush plate after the tiling has already been completed — whether due to renovation, compatibility issues, or simply deciding to upgrade to a cleaner and more modern solution like the under-tile flush plate.

What to Expect

Because the opening in the tiles is already fixed, the installer needs to carefully adjust the existing cut-out. The process requires a bit more precision and patience compared to installation during tiling, but it’s manageable and usually without complications if done correctly.

Our system is designed so that the plate sits cleanly and securely even when retro-fitted. The result is visually seamless and fully functional.

Useful Tip

If your current opening is slightly smaller or uneven, it may need to be carefully enlarged. A diamond blade.

Final Word

So yes — even if your tiles are already finished, you can install the under-tile flush plate without tearing down your wall. It’s not the textbook scenario, but it works and it’s common practice.

How to Install an Under-Tile Flush Plate — Step-by-Step Guide

If you want a minimalist, seamless bathroom look, installing a flush plate hidden under the tiles is an impressive solution. The process isn’t complicated, but precision is crucial — especially when cutting plasterboard and tiles. Below is a practical guide to help you complete the installation smoothly and professionally.

1. Preparing the Plasterboard or Plaster (Ytong) Panels

Start by cutting two installation panels that will support the mechanism.

Panel Cutting

• Cut the first panel to 210 mm x 109 mm.

• Cut the second panel to 238 mm x 155 mm.

If you’re working with plaster (Ytong), use the same procedure as for plasterboard.

Drilling and Preparing the Mounting Area

• Drill six holes (as marked in the technical drawing) to allow the adjustment screw threads to pass through the first panel.

• Cut the protective collar so that it is flush with the front surface of the first panel.

2. Mounting the Plastic Frame to the Toilet Tank

Installing the Rear Part of the Flush Plate

1. Insert the rear mounting frame and secure it using the plastic pins in the marked locations.
   Break off the excess pin length so everything sits flush.

2. Tighten the locking wedges to fix the frame firmly in place.

3. Install and secure the flush rods, adjusting them with the screws to ensure proper toilet operation and avoid leaks.

4. Use the six adjustment screws to align the surface of the flush plate perfectly with the surrounding tiles.

3. Cutting the Tile

This step requires precision and professional tools.
It must be done by a qualified tiler with experience in cutting tiles for concealed mechanisms. Incorrect cutting may ruin the tile or prevent proper installation — don’t improvise here.

4. Gluing the Tile to the Flush Plate

Use a strong, flexible adhesive intended for this purpose, for example Soudal Fix All.

Tile Bonding Procedure

• Thoroughly degrease the back side of the tile.

• Apply adhesive evenly to the prepared surface of the front part of the flush plate.

• Place the tile onto the plate and align the joints with surrounding wall tiles.

• Use wedges for perfect positioning and fixing of the joint width.

• Allow the adhesive to cure for at least 12 hours without movement.

5. Installing the Finished Front Flush Plate

Once the adhesive has fully set:

• Mount the front tile-covered plate onto the adjustment screws of the rear mechanism.

• Press gently until it locks securely in place.

And you’re done — the flush plate is now perfectly integrated into the wall, visually indistinguishable from the rest of the tiled surface, providing a clean and luxurious look.

Final Thoughts

A concealed under-tile flush plate adds premium aesthetics to any bathroom. Precision and patience are key. If you follow these steps carefully (and trust a professional tiler for the cutting), the result will look outstanding and will last for years.
