Start with the room
Describe whether the project involves a shower, tub surround, floor or backsplash. Share photos of the entire area as well as close-ups of existing finishes and transitions.
Collect a focused set of ideas
Choose a few examples rather than a large collection. Note what you like about each: tile size, color, pattern or grout contrast. Keep the examples as inspiration rather than a final specification.
Think about everyday care
Ask about the suitability and care needs of the products you are considering. Bring product names or samples if you have them so the discussion can be specific to your choices.
Clarify the boundaries
List any changes beyond tile that you are considering. Plumbing, electrical work and a full bathroom remodel should not be assumed to be part of a tile project; discuss any additional needs separately.
