Bathroom tile and flooring work covers a lot more than setting pretty tile. It includes tearing out old flooring, checking the subfloor for rot or soft spots (common in older Shelton homes near the Housatonic where moisture gets into joists), building a proper waterproof shower pan or curb, laying cement board or a membrane system, and then setting tile with the right thinset and grout for a wet environment. Some jobs also involve heated floor mats under the tile, which need to be tested before anything gets covered up.
When you're comparing the 10 businesses in this category, ask who actually pulls the permit, how they handle waterproofing at the shower pan and curb (this is where most failures happen), and whether they level the subfloor before tile goes down rather than just tiling over an uneven surface. Get a written scope that names the underlayment and waterproofing products, not just "tile installation."
Our scoring weighs licensing, verified reviews mentioning tile and waterproofing specifically, response time, and whether a business shows finished bathroom work rather than generic flooring photos.
