also, avoid veneer in bathrooms as Veneer sheets are softer than laminate sheets. Once the polish layer wears off over time, the veneer becomes susceptible to abrasions. The veneer sheet may bubble or warp if moisture seeps into the core material or if the top layer is exposed to heat. So they are not great options for kitchens, bathrooms and other wet areas.

It’s great you're focusing on recycling! If the dado tiles are in good condition and neutral, you can leave them, but check grout and overall security. When replacing bathroom floor tiles, ensure the waterproofing layer remains intact, as redoing it can prevent water damage. For plywood, if the quality is good, you can reuse it, but ensure a skilled carpenter finishes it properly. The kitchen countertop can be reused if carefully removed and in good shape. Just make sure all structural and waterproofing aspects are intact.
