I'm in the middle of renovating my small bathroom, and my contractor suggested tiling over the existing tiles instead of removing them. The old tiles are over 20 years old, but the contractor insists they're still in good condition. This renovation isn't just a tile job; it's a complete remodel. One concern I have is that one wall is only 7 cm thick drywall; I'm doubtful if it's strong enough to support two layers of tiles. I've attached some pictures for reference.

It sounds like your contractor might prefer this method because it's cheaper and saves time. But you should definitely ask if the quote reflects that. Also, you need to consider how the new floor will be leveled and if the drain will be at the correct height after tiling over the old tiles. Plus, remember that tiles alone don't waterproof the bathroom; you usually need a moisture barrier underneath.
True! I've heard tiling over existing tile is often a shortcut for contractors. It seems like a lazy solution unless specific conditions like asbestos are involved. What's your opinion on that thin drywall? I'm worried it's not even strong enough for one layer of tiles.
Honestly, I would be cautious about having them tile over the old tiles. Regardless of the condition of the existing tiles, going over them can create future issues, especially with moisture and proper adhesion. Make sure to get clear answers from your contractor about their entire plan before proceeding!
I get your point! The contractor is removing some tiles, but he mentioned not taking the ones off the drywall, which worries me. I didn't know tiling over was even an option before we agreed to the full renovation.
