Calculadora de Baldosas Gratis — Piezas y Cajas (2026)

Cómo Usar Esta Calculadora

1. 1Measure the room length and width in feet.
2. 2Enter the tile size in inches (e.g., 12 for 12x12 tiles).
3. 3Set waste percentage (10% standard, 15% for diagonal layouts).
4. 4Click Calculate to get tile count, boxes, grout, and thinset estimates.

Sobre Este Material

Tile flooring includes ceramic ($1–$5/sq ft), porcelain ($3–$10/sq ft), natural stone ($5–$20/sq ft), and glass mosaic ($10–$30/sq ft). Porcelain is the most popular for floors because of its durability and water resistance — it has a water absorption rate below 0.5%, making it suitable for bathrooms, kitchens, and outdoor applications. Common floor tile sizes are 12x12, 12x24, 18x18, and 24x24 inches. Larger tiles cover faster but require a flatter subfloor (1/8 inch tolerance over 10 feet for tiles over 15 inches). Thinset mortar is the standard adhesive — use modified (polymer-modified) thinset for porcelain and natural stone. Grout comes in sanded (for joints 1/8 inch and wider) and unsanded (for joints under 1/8 inch). Epoxy grout is more expensive but resists staining and does not need sealing. Budget $0.50–$1.50/sq ft for professional thinset and grout materials. Professional tile installation costs $5–$15 per square foot including labor and materials. A 50 lb bag of thinset covers 60–80 sq ft, and a 25 lb bag of grout covers 50–70 sq ft depending on tile size and joint width.

Consejos de Instalación

• •Dry-lay tiles before applying thinset to plan cuts and check the layout.
• •Use a notched trowel matched to tile size — 1/4x3/8 for 12x12 tiles, 1/2x1/2 for larger.
• •Back-butter large-format tiles (over 15 inches) in addition to troweling the floor.
• •Use a tile leveling system (clips and wedges) to prevent lippage on large tiles.
• •Wait 24 hours after setting tiles before grouting to allow thinset to cure.

Errores Comunes a Evitar

• ⚠Not using enough thinset — hollow spots under tiles lead to cracking under load.
• ⚠Skipping waterproofing membrane in wet areas like showers and bathroom floors.
• ⚠Using unsanded grout in joints wider than 1/8 inch — it will crack.
• ⚠Not mixing thinset properly — let it slake for 10 minutes, then remix before applying.
• ⚠Cutting waste too low — complex layouts and diagonal patterns need 15–20% waste.
