Quick Answer: Grout typically runs $15 to $40 per bag as of 2026, with cementitious sanded at the low end, epoxy and urethane in the middle, and specialty and performance grouts at the top. The price you actually pay moves with chemistry, color, joint width, and the regional market. Use the ranges below as a planning anchor, then pull current quotes from your suppliers for the bid date.
What Drives the Price
Chemistry is the biggest single driver. Cementitious grout is the baseline product, it is a blend of Portland cement, pigments, and fillers, and it owns the low end of the range because the raw materials are cheap and the formulation is mature. Within cementitious, sanded grout is for joints 1/8 inch and wider, unsanded is for joints under 1/8 inch and for polished stone where sand would scratch, and both sit at the same low price tier. Epoxy grout is the premium tier, it is a two part system of resin and hardener plus filler, it resists stains, water, and chemicals, and it owns commercial kitchens, baths, and high traffic floors, but it costs two to four times what cementitious costs and is harder to install. Urethane and single component ready to use grouts sit in the middle, they combine cement free flexibility with easier installation, and they have taken share on residential tile work where stain resistance matters but epoxy is too expensive.
Color and formulation move the number within each chemistry. White and light gray are the cheapest because the pigments are simple. Dark and saturated colors (blues, greens, blacks) carry a premium of $2 to $8 per bag for the pigment package, and custom colors run higher still. Performance additives add to the price: polymer modified cementitious grout is more flexible and less prone to cracking, antimicrobial and stain resistant additives add $2 to $5 per bag, and fast setting and high traffic formulations run at the top of each chemistry tier. Bag weight matters too. A 25 lb bag is the baseline for residential tile, a 10 lb or 3 lb box is for small and repair jobs where the premium per pound is worth the convenience, and larger commercial packaging cuts the per pound price on volume work. Region and volume round out the drivers. Cement and pigment pricing move with the commodity market, and freight from the plant to your market matters because grout is heavy for its value. Volume buyers pull case and pallet pricing 10 to 25 percent below single bag retail.
Typical Price Ranges by Type
These ranges cover material only, not labor, and are typical as of 2026. Add $1.50 to $4.00 per SF for mixing and grouting on small jobs, less on production tile work.
- Cementitious sanded grout (25 lb bag): $15 to $25 per bag. Joints 1/8 to 1/2 inch, floor and wall tile, general purpose.
- Cementitious unsanded grout (25 lb bag): $15 to $26 per bag. Joints under 1/8 inch, polished stone, ceramic wall tile.
- Polymer modified cementitious grout: $20 to $30 per bag. Better flexibility, less cracking, high traffic residential.
- Urethane and single component ready to use grout: $30 to $45 per bag or pail. Stain resistant, flexible, easier install than epoxy.
- Epoxy grout (two part, 1 to 2 gallon kit): $45 to $90 per kit. Commercial kitchens, baths, high stain and chemical work.
- Fast setting and high traffic grout: $25 to $35 per bag. Production tile, cold weather, and fast turnaround work.
- Specialty grouts (premixed, antimicrobial, colored): $20 to $40 per unit. Custom color, stain and mold resistance, repair and small job packaging.
Case and pallet pricing cuts the per bag price 10 to 25 percent on volume jobs. If your floor runs more than a few bags, ask for the case rate, the savings show up fastest on the cementitious sanded line because that is the most common spec.
How to Calculate the Quantity You Need
Grout takeoff is driven by tile square feet, joint width, and tile thickness (joint depth). A 25 lb bag of sanded grout typically covers 75 to 150 square feet at a 1/8 inch joint with 4x4 tile, 50 to 100 SF at a 1/4 inch joint with 6x6 tile, and 25 to 50 SF at a 3/8 inch joint with 12x12 tile. The rule is simple: wider and deeper joints take more grout per square foot, so a 12x24 tile with a 3/8 inch joint can take three times the grout per SF that a 4x4 tile with a 1/8 inch joint takes. Use the manufacturer coverage chart for the exact tile size and joint width, because the chart is the only accurate source.
Apply a 10 percent waste factor for production work, 15 to 20 percent for small jobs or colored grout where you throw away partial bags to avoid batch color mismatch. Round up to the case (4 to 8 bags per case) to keep color consistent, because mixing batches is the fastest way to a visible color line. Add sealer on its own line if the spec calls for it. Tie every quantity to the tile schedule and note the joint width you assumed.
How to Buy Smarter
- Get three supplier quotes on the same chemistry, color, and bag size. Grout pricing varies 15 to 30 percent between distributors on identical spec, especially on epoxy and urethane.
- Quote each chemistry on its own line. Mixing cementitious, urethane, and epoxy into one line hides the real cost and lets a sub swap to a cheaper product.
- Buy by the case on volume jobs and keep the lot number consistent. Color can vary between lots, so a single lot keeps the floor uniform.
- Lock quotes for 30 to 60 days on longer bids. Grout moves with cement, pigment, and resin pricing, so a stale quote is a losing quote.
- Specify the product by name, chemistry, and color, not just "grout." A generic spec lets the low bidder substitute a cementitious grout where epoxy was needed for stain resistance.
- Match the bag size to the job. A 25 lb bag is cheapest per pound on production work, but a 3 lb box wins on a small repair where the 25 lb bag goes to waste.
Where Estimators Get It Wrong
The most common mistake is treating all grout as one line. An epoxy kit costs three to four times what a cementitious bag costs, so a blended line either overprices the floor or underprices the kitchen. The second is using the wrong coverage chart. Estimators who assume 100 SF per bag on every job lose money on a 12x24 tile with a 3/8 inch joint that yields 30 SF. The third is forgetting sealer, often $0.10 to $0.30 per SF on a cementitious spec. The fourth is using retail box store pricing, while a tile supply house has case pricing 20 to 40 percent lower. The fifth is ignoring color and lot premiums, which can add $5 to $10 per bag and trigger a callback when lots mix.
Putting It Together
Build your grout line from the spec up: list each chemistry separately, price it by the case at the right bag size, and calculate bags from the tile schedule using the manufacturer coverage chart at the actual joint width. Add sealer on its own line where the spec calls for it. Pull three current quotes, keep the lot consistent, and lock them for 30 to 60 days. Grout is a small line that leaks big money when it is mispriced, so a clean takeoff and separate lines per chemistry are what keep the joints full and the margin in.
