Challenges and Risks:
* Freezing Temperatures: Water trapped beneath tiles will freeze and expand, causing significant damage to the tiles, mortar, and even the pool shell.
* Frost Heave: The ground around the pool will freeze and thaw, potentially lifting and shifting the tiles.
* Water Penetration: Even with careful installation, water can seep under the tiles, leading to freezing and cracking.
* Structural Issues: Removing the liner and installing tiles can impact the structural integrity of the pool. The liner helps distribute pressure and provides some flexibility.
* Dog Damage: Dogs can still damage tiles, potentially creating tripping hazards and leaving behind messes.
* Cost and Complexity: Replacing a pool liner is generally a simpler and less expensive solution than tiling the entire pool floor.
Alternatives:
* Stronger Liner: Consider upgrading to a thicker, more puncture-resistant liner.
* Protective Covering: Install a heavy-duty pool cover designed for winter use.
* Mesh Fence: Create a barrier around the pool to keep dogs away.
* Training: Train your dogs to avoid the pool area.
Recommendation:
Instead of removing the liner and installing tiles, focus on protecting the existing liner and preventing dog damage. Contact a pool professional for expert advice on the best course of action.
