How do I remove old bathroom tile?

Removing old bathroom tile requires the right tools and technique to avoid damaging the wall surface underneath. Start by removing grout with a manual grout removal tool or oscillating multi-tool, then use a hammer and chisel or reciprocating saw to break tiles away from the wall.

Begin with proper preparation by turning off electricity to any switches or outlets in the work area and covering floors and fixtures with plastic sheeting. Remove all grout lines first using a manual grout removal tool, rotary tool with grout removal attachment, or oscillating multi-tool. This step is crucial - trying to remove tiles with grout still in place often damages the drywall behind.

For tile removal itself, start at corners or edges where possible. Use a hammer and cold chisel, positioning the chisel at a 30-degree angle behind the tile. Work systematically across the wall, being careful not to gouge the drywall. A reciprocating saw with a tile removal blade can speed up the process on larger areas, but requires more skill to avoid wall damage. Always wear safety glasses and a dust mask - tile removal creates sharp fragments and dust.

In Ottawa's older homes, you may encounter tiles installed over plaster walls or even directly over wood lath. These surfaces are more fragile than modern drywall, so work more carefully and expect some surface repair afterward. If you discover asbestos-containing materials (common in homes built before 1980), stop work immediately and consult with a certified abatement contractor.

After tile removal, scrape off remaining adhesive with a putty knife and sand smooth any high spots. You'll likely need to prime and patch the wall surface before installing new tile. Consider the scope of your project - if you're planning a full bathroom renovation with plumbing or electrical changes, this is an ideal time to have licensed contractors handle the entire job, ensuring proper waterproofing and code compliance.

For extensive tile removal or if you discover complications like water damage or structural issues, request a consultation with experienced renovation contractors who can assess the full scope of work needed.
