✅ When It’s Okay
You can tile over existing tiles if:
1. The old tiles are firmly fixed — no loose or hollow-sounding tiles.
2. The surface is flat and level — uneven tiles will make the new layer unstable.
3. There’s enough height clearance — adding new tiles raises the floor, which might affect door clearance or appliances.
4. The existing surface is clean and grease-free — use a good degreaser before applying adhesive.
5. You use the right adhesive, specifically one designed for “tiling over tiles” (usually a flexible tile adhesive).
⚠️ When You Shouldn’t
• The old tiles are cracked, loose, or damaged.
• The surface underneath has moisture or movement issues.
• You’re tiling over vinyl, wood, or uneven flooring — those should be removed.
🧱 Tip
If you’re unsure about the old tile condition, it’s safer to remove them first. That way, you avoid potential issues with adhesion or uneven levels later.
