Can tile be salvaged when the rotted sub flooring is replaced under the toilet?

Yes, it is possible to salvage your 12x12 tile when replacing rotted subflooring under a toilet, but it can be tricky. The success of salvaging the tile largely depends on how well it was installed and the condition of the adhesive used.

Here are some steps you can take:

1. **Assess the Tile**: Carefully examine the grout lines and the surrounding tiles for any cracks or damage. If the tiles are in good condition, you can proceed.

2. **Remove the Toilet**: Before working on the subfloor, remove the toilet. Make sure to turn off the water supply and drain the tank.

3. **Lift the Tiles**: Use a chisel and a hammer to gently pry up the tiles. Start from the edges and work your way inward. Be cautious to minimize breakage.

4. **Replace the Subfloor**: Once the tiles are removed, replace the rotted subfloor with new plywood or OSB, ensuring it is level and properly secured.

5. **Reinstall the Tiles**: After the subfloor is replaced, you can reapply the tiles using fresh adhesive. Regrout the joints once the adhesive has set.

Costs for this type of work can vary widely, typically ranging from $200 to $600, depending on your location and the complexity of the job. For best results, consider hiring a licensed professional who can ensure the job is done correctly.
