The short answer
Pros charge by the square foot of tile. Floors cost $5–$11 per square foot to regrout. Showers and tub walls cost $7–$28. Most of what you pay for is labor: the slow work of cutting the old grout out of every gap.
In plain English: a floor is cheap, a shower costs more, and tiny mosaic tiles cost about double. If your tiles are loose or the wall behind them is wet, new grout will not fix it. Then you are pricing new tile instead.
A worked example, start to finish
Say you have a shower with 60 square feet of 4 × 12 inch tile. The grout is cracked in a lot of places, but the tiles are solid. You want sanded grout and you want it sealed. These are the calculator's default settings, so you can check every number.
- Regrouting: 60 sq ft × $7 = $420 at the low end, and 60 × $28 = $1,680 at the high end.
- Sealing: 60 sq ft × $1 = $60, up to 60 × $2.46 = $147.60.
- Total with a pro: $480 to $1,828. The middle of that range is $1,154. That middle figure is our own midpoint, not a number any publisher printed.
- About 62.5% of the middle figure, or $721, is labor.
- Doing it yourself: one 25 lb bag of sanded grout ($21.43), one quart of sealer ($19.97), a grout saw, a rubber float and sponges ($27.38). That is $68.78, or $84.28 if you also buy a grout blade for an oscillating tool you already own. (An oscillating tool is a hand-held power tool whose blade shakes quickly side to side.)
How much grout is that? A 4 × 12 inch tile has 4 feet of grout line in every square foot, so 60 square feet has 240 feet of line. Filled 1/8 inch wide and 3/8 inch deep, that is 135 cubic inches, or about 8.61 pounds. One 25 lb bag covers it.
What grout is, and why it fails
Grout is the hard paste in the gaps between tiles. Those gaps are called joints. Most grout is cement-based, which means it is a little like a thin mortar. Cement grout is full of tiny holes. It soaks up water, soap and dirt unless it is sealed. Sealing means brushing on a clear liquid that blocks those holes.
Over the years grout cracks, stains, grows mold or crumbles out. Floors crack where the floor flexes. Showers fail where water sits. Regrouting means cutting the old grout out and filling the joints again. It makes the tile look new and stops water getting behind it, without paying for new tile.
How pros price it
- By the square foot of tile. Walls cost more than floors because the work is slower and showers have corners and fixtures.
- Labor is most of the bill. Fixr says labor is 45% to 60% of the job, This Old House 60% to 80%, Block Renovation 70% to 80%. Removing the old grout is the slow part.
- Small jobs hit a minimum. Many pros will not come out for less than a set fee. This Old House prints $200–$300. Fixr prints $50–$100 and Block Renovation $250–$500.
- Epoxy and mosaic cost more. Epoxy grout works out at about 1.5 times the price of sanded (Fixr's own prices give 1.50; This Old House's give 1.43). Mosaic tile has so many joints that Fixr says it often costs double. The calculator applies ×1.5 and ×2.
The calculator's formula, now that you have seen it work:
pro price = square feet × area rate × grout factor × mosaic factor + sealing
sealing = square feet × $1–$2.46 (cement grout only)
then lifted to the minimum charge if it comes out lower
Price per square foot by area
| Where | Per sq ft (pro) | Cross-check |
|---|---|---|
| Shower (walls and floor) | $7–$28 | Angi's shower repair band: $250–$900 per job |
| Tub surround (three walls) | $7–$28 | Fixr's bathtub regrout band: $800–$1,200 per job |
| Bathroom floor | $5–$11 | Angi's tile floor repair band: $150–$600 per job |
| Kitchen floor | $5–$11 | Angi's tile floor repair band: $150–$600 per job |
| Kitchen backsplash | $5–$13 | Angi's backsplash repair band: $100–$350 per job |
The per-square-foot bands are HomeGuide's. Block Renovation prints the same $5–$11 for floors, and HomeAdvisor's $10–$25 for showers sits inside HomeGuide's shower band. The cross-check column is a whole-job figure from another publisher. It is shown so you can sanity-check a quote. It is never added to your price.
Sanded, unsanded or epoxy?
| Grout | Gap width | Best for | Pro, shower (per sq ft) | Good | Watch out |
|---|---|---|---|---|---|
| Sanded (cement with sand) | 1/8 in and wider | Floors and most wall tile with gaps of 1/8 inch or more. | $6–$8 | Cheapest per bag. Strong in wide gaps. | Can scratch polished stone and glass. Needs sealing. |
| Unsanded (fine cement, no sand) | up to 1/8 in | Thin gaps on wall tile, glass and polished stone. | $5–$6 | Smooth and easy to press into thin joints. Will not scratch. | Shrinks and cracks in wide gaps. Needs sealing. |
| Epoxy (resin, two parts) | most widths | Showers, kitchens and anywhere stains or mold are a problem. | $8–$12 | Does not stain, does not need sealing, lasts longest. | Costs three to five times more than cement grout (Block Renovation). Sets fast and is hard to clean off tile. |
The per-square-foot column is what Fixr and This Old House print for a shower; the two agree. At the store, sanded grout is $21.43 for a 25 lb bag and unsanded is $18.48 for 10 lb. Epoxy is $124.50 for an 11 lb kit. These are Home Depot prices, read 16 October 2026.
When to regrout, and when to retile
Grout only fills gaps. It does not glue tiles down and it does not dry out a wet wall. Do these checks before you pay for new grout:
- Tap each tile with the handle of a screwdriver. A dull, hollow sound means the tile has come loose from the wall or floor.
- Push on the tile. If it moves or flexes, the backing behind it may be soft or rotten.
- Look around the shower. Peeling paint, a soft wall, or a stain on the ceiling below all point to water behind the tile.
- Look at the tiles themselves. Several cracked tiles usually mean the floor is moving. New grout will crack again.
If all of that passes, regrout. If not, get a tiler to look at the wall first. Retiling costs $9–$37 per square foot on HomeGuide (Block Renovation prints $10–$50 for new tile), so it is several times the price of a regrout. Price new tile on the tile flooring installation calculator, or a whole room on the bathroom remodel cost calculator.
When a repair or a clean is enough
A few bad lines? A grout repair cuts out and refills only the damaged joints. Angi prices it at $50–$250 for a small job, and Fixr at $150–$200. The new grout may not match the old color exactly.
Dirty but solid? If the grout is stained but still hard and whole, a deep clean and seal may be all it needs. HomeGuide and Block Renovation both print cleaning at $0.50–$3.50 per square foot, and HomeGuide says most cleaning companies charge at least $100–$200.
Doing it yourself
Regrouting is a job many homeowners can do. It is slow, dusty and hard on the hands, and the real risk is chipping tile edges while cutting out the old grout. HomeGuide says a first DIY regrout takes 2 to 3 days, against 1 to 2 days for a pro.
The steps
- Check the tile. Tap each tile. If any sound hollow or move, or the wall is soft, stop and get a tiler to look: new grout will not fix that.
- Cut out the old grout. Run the grout saw or oscillating blade down the middle of each joint until most of the old grout is out. Do not chip the tile edges.
- Vacuum and wipe. Vacuum the dust out of the joints and wipe the tile with a damp sponge.
- Mix and spread the grout. Mix only what you can spread before it starts to stiffen; the bag says how long that is. Press it into the joints with the rubber float held at an angle, working diagonally across the tile.
- Wipe off the haze. When the grout firms up, wipe the tile with a barely damp sponge, rinsing often. Buff off the dry haze later with a soft cloth.
- Let it harden, then seal. Keep water off it for as long as the bag says. Then brush sealer onto cement grout. Epoxy grout needs no sealer.

Sealing: how often and what it costs
Cement grout should be sealed once it has fully hardened, then resealed every 1 to 3 years (Block Renovation). A pro charges about $1–$2.46 per square foot: Fixr prints $1–$2 and Homewyse $1.35–$2.46. This Old House prints a higher $2–$5. Doing it yourself, one $19.97 quart covers up to 150 square feet. Epoxy grout never needs sealing.
Questions to ask a contractor
- Will you remove all of the old grout, or only the top layer?
- Is the price per square foot or for the whole job? Is there a minimum?
- Which grout do you recommend for this tile, and why?
- Is sealing included? Which sealer, and when do I reseal?
- Will you recaulk the corners and the joint where tile meets the tub?
- Did you check for loose tiles or water damage? What if you find some?
- How long before we can use the shower again?
- Are you licensed and insured, and do you guarantee the work?
HomeAdvisor's prices include removing all of the old grout. If one quote is far below the others, ask whether it does too.
Where the publishers disagree
- Regrouting per square foot: HomeGuide $7–$28 for showers, HomeAdvisor $10–$25 for showers, Fixr $5–$12 for showers, Homewyse $15.84–$34.75 for tile in general. The calculator uses HomeGuide's band because it is the only one split by area, and its midpoint is ours, not theirs.
- Sealing: Fixr $1–$2, Homewyse $1.35–$2.46, This Old House $2–$5. The calculator uses $1–$2.46.
- Minimum charge: Fixr $50–$100, This Old House $200–$300, Block Renovation $250–$500. The calculator uses This Old House's, the middle one.
- Does bad grout cost more to remove? HomeGuide says crumbling grout can be easier to cut out. Fixr says old grout that comes out easily is cheaper. Because they do not agree, condition changes the calculator's advice, not its price.
Methodology
- All cost figures are US national and come from the sources below, each read on 16 October 2026. The cost guides are secondary sources. Their pages are dated from December 2023 (HomeGuide) to October 2026 (Angi). Most were updated in 2025 or 2026.
- Low and high come straight from the published bands. “Typical” is the midpoint of the two and is our own figure.
- The grout factor (epoxy ×1.5) and the mosaic factor (×2) are taken from Fixr's own prices. Unsanded and sanded grout are priced the same. On Fixr and This Old House they differ by only $1 per square foot, which is less than the width of any area band.
- The grout quantity uses the manufacturer's coverage answers on the Home Depot page for Polyblend Plus: about 392 cubic inches of joint per 25 lb bag. The calculator fills joints 3/8 inch deep, which slightly overestimates a regrout.
- The labor share of 62.5% is the middle of the 45% to 80% the publishers print. It splits the typical price into labor and materials and weights the metro adjustment.
- No publisher prints a regional price for grouting. The metro option uses federal wage data for floor layers and tile setters (U.S. Bureau of Labor Statistics, May 2025). It moves the labor share only. The site's other renovation calculators use the same data. Metros without a published tile-setter wage are left out, not guessed.
- Not priced: water damage behind the tile and replacing broken tiles. Only one publisher we could read prices water damage, and none prices replacing a few broken tiles, so both are left out rather than guessed. Recaulking the corners is also extra: Fixr prints $150–$300.

Grout repair and clean-and-seal jobs are priced from the same publishers. New tile is out of scope and priced on the tile installation calculator.). Floors are the cheapest to regrout at $5-$11 per sq ft, a band HomeGuide and Block Renovation print identically. Showers, tub surrounds and bathroom walls run $7-$28 per sq ft on HomeGuide, and HomeAdvisor's $10-$25 for showers sits inside that. Labour is most of the bill: publishers put it at 45% to 80% of the job. No regional figure is published for grouting, so the metro option reuses the site's BLS wage data for tile setters on the labour share only. Last verified October 2026.

Frequently asked questions
How much does it cost to regrout a shower?
Take a typical 60 square foot shower with 4 × 12 inch tile, sanded grout and sealing. This calculator gives $480–$1,828, with $1,154 as its midpoint. That comes from HomeGuide's $7–$28 per square foot for showers plus $1–$2.46 per square foot to seal. Other publishers land inside that range: This Old House puts the average shower at about $1,500, and Fixr puts an 80 square foot shower at $560 to $880.
How much does regrouting cost per square foot?
Floors are cheapest at $5–$11 per square foot, a band HomeGuide and Block Renovation print the same. Showers, tub surrounds and bathroom walls run $7–$28 per square foot on HomeGuide. A kitchen backsplash is $5–$13. Epoxy grout costs about 1.5 times as much, and small mosaic tile about double.
Is it cheaper to regrout or retile?
Regrouting is much cheaper when the tile is sound. HomeGuide prices retiling a bathroom at $9–$37 per square foot, against $7–$28 to regrout a shower. But regrouting only works if the tiles are firmly stuck and the wall behind them is dry. If tiles are loose, cracked, sound hollow when tapped, or the wall is soft or stained, new grout will not fix it and retiling is the real job.
How much does a small grout repair cost?
Patching a few cracked or missing lines is $50–$250 as a small job, according to Angi. Fixr prints $150 to $200 for a minor grout repair, inside that range. Many pros also have a minimum charge, so fixing three lines can cost about the same as fixing ten.
Can I regrout tile myself?
Yes. For the 60 square foot shower example, the grout, sealer and hand tools come to about $68.78 to $84.28 at Home Depot prices read 16 October 2026. The hard part is cutting the old grout out without chipping the tile. HomeGuide says a first DIY regrout takes 2 to 3 days, against 1 to 2 days for a pro.
Should I use sanded, unsanded or epoxy grout?
Use sanded grout for gaps 1/8 inch and wider, which covers most floors. Use unsanded grout for thin gaps on wall tile, glass or polished stone, because sand can scratch them. Use epoxy where stains and mold are a problem, such as a shower: it never needs sealing, but pros charge about 1.5 times as much for it.
Can new grout go over old grout?
No. HomeGuide says new grout should not be put over old grout, because it can crack and can hide water damage underneath. The old grout has to be cut out first, and that removal is most of what you pay a pro for.
