Separate areas make those scopes comparable and prevent a simple floor rate from understating detailed vertical wet-area work."},{"question":"What belongs in the plumbing fixture allowance?","answer":"List the tub or shower base, valves, trim, showerhead, toilet, faucets, sinks, drains, supplies, and accessories intended for purchase. State whether delivery, tax, installation, rough-in changes, blocking, disposal, and finish repairs are included; the retail fixture price rarely covers every dependency."},{"question":"Does this bathroom estimate include waterproofing?","answer":"Only if an entered installed tile rate or trade quote expressly includes the specified waterproofing system and preparation. Tile and grout alone are not the complete water-management assembly. Require compatible products, installation details, drain coordination, penetrations, transitions, and any applicable testing in writing."},{"question":"How much contingency should a bathroom remodel carry?","answer":"Choose contingency from design completeness, building age, investigation, concealed plumbing, moisture risk, access, product decisions, and contract structure. It should cover uncertainty, not known omitted work. Older bathrooms with unopened walls may justify more protection than a fully documented recent assembly."}],"sources":[{"name":"Tile Council of North America — Resource Center","url":"https://tcnatile.com/resource-center/","note":"Tile-industry installation resources covering substrates, waterproof assemblies, movement accommodation, mortar, grout, and material selection."},{"name":"Federal Trade Commission — How To Avoid a Home Improvement Scam","url":"https://consumer.ftc.gov/articles/how-avoid-home-improvement-scam","note":"Federal consumer guidance on contractor checks, multiple written estimates, itemized scope, contracts, and payment practices."},{"name":"U.S. EPA — Lead Renovation, Repair and Painting Program","url":"https://www.epa.gov/lead/renovation-repair-and-painting-rrp-program-consumers","note":"Federal guidance for renovation work that may disturb lead-based paint in pre-1978 housing, including painting and window replacement."}],"defaultCalculation":{"inputs":{"floorArea":80,"floorRate":0,"wallArea":120,"wallRate":0,"fixtureAllowance":0,"vanityAllowance":0,"tradeLabor":0,"fixedFees":0,"contingency":15},"result":{"value":"Add local quotes","unit":"to build budget","label":"Bathroom remodel budget","lines":[{"label":"Floor finish","value":"Not entered"},{"label":"Wall tile","value":"Not entered"},{"label":"Plumbing fixtures","value":"Not entered"},{"label":"Vanity, top, and storage","value":"Not entered"},{"label":"Other construction and trades","value":"Not entered"},{"label":"Contingency","value":"Not added"}],"summary":"The physical scope is calculated, but no budget is shown until you enter at least one current local price or written quote.","note":"The calculator includes only entered components.
