If looking at the grout in your shower makes you want to bathe in the dark, it might be time to get it replaced. Your average-sized shower could cost anywhere between $565 to $1,750 for a full regrout, with prices hinging on the type of grout as well as how much old grout needs to be removed. We break down what you can expect to pay below.

How Much Does Regrouting Cost for Different Shower Sizes?

Below are average tile regrouting prices for a few standard shower sizes. These sizes assume that the shower has three walls of tile and a height of 7 feet:

  • 32-by-32-inches (56.07 sq. ft.): $565–$1,405

  • 36-by-36-inches (63 sq. ft.): $630–$1,575

  • 36-by-48-inches (70 sq. ft.): $700–$1,750

Cost to Regrout by Grout Type

There are many types of grout, and they each feature unique price ranges, pros, and cons. Here are the major group types to choose from. 

Unsanded Grout 

Unsanded grout is on the more affordable side, at $5 to $6per square foot. So, the typical cost to regrout an 80-square-foot shower is $400 to $480. This type of grout is used on smaller-than-average joints of 1/8-inch or less, as it shrinks when it dries. 

Unsanded grout is extremely common in many bathrooms, particularly guest bathrooms, as it’s easy to install, relatively affordable, and available in many different colors, from white and light gray to more speciality designs. Unsanded grout lasts around 10 years before it needs to be regrouted (assuming you take good care of it). 

Sanded Grout

Sanded grout is slightly more expensive than its unsanded cousin, coming in at $6 to $8 per square foot (or $480 to $640 to regrout an 80-square-foot shower). This is the same mixture as unsanded grout, but, as the name suggests, with the addition of sand. 

This sand makes it thicker and more durable than unsanded grout, allowing it to fill wider joints without cracking as it dries. Sanded grout lasts as long as 20 years before it needs to be replaced. 

Cement Grout 

 Cement grout costs $5 to $7per square foot, so you’ll pay $400 to $600 to regrout a traditional 80-square-foot shower. This is an extremely common grout type, as it is budget-friendly, easy to apply, and is available in a wide range of colors. 

However, cement grout is not typically recommended for showers, as it cracks over time and eventually discolors as it deals with near-constant moisture. While not great for showers, cement grout is fantastic as a base for tile work and home fixtures. 

Polymer Grout

Polymer grout is on the pricier side, costing $6.50 to $10per square foot or $560 to $880 for 80 square feet of coverage. This is essentially cement grout with the addition of acrylic polymers, which addresses many of the issues with using cement grout in bathrooms and showers. 

Polymer grout is durable, long-lasting, and does well with moisture. It is harder to apply than many other grout types, as it remains stiff and difficult to spread, though it does not require sealing after installation. Additionally, some polymer additives include volatile organic compounds (VOCs), which give the grout a strong odor. If you are sensitive to VOCs, or simply concerned, talk to your pro and request a brand without these chemicals. 

Epoxy Grout 

Epoxy grout is far and away the most expensive type, at $8 to $12per square foot or $720 to $960 for an 80-square-foot shower. Much of this added price falls down to labor costs, as it is difficult to spread and is mixed directly before being applied. 

However, you get what you pay for, as epoxy grout is flexible, so it won’t crack over time, and resists staining and discoloration, as it is completely non-porous. Epoxy resin-based grout is available in unsanded and sanded varieties, but both include plenty of VOCs, so prepare for a strong odor immediately following installation. Not every pro is familiar with this grout type, so talk to your installer ahead of time to discuss their experience level. 

Cost to Regrout by Tile Type 

The tiles themselves also dictate the price to regrout a shower, as both the type of tile and the space between each piece influences which type of grout will work best. 

  • Machine-made wall tile: This tile type does best with unsanded polymer, though it integrates nicely with many grout materials. You’ll pay $400–$800per shower when regrouting between machine-made wall tiles. 

  • Handmade wall tile: Handmade tiles benefit from the added durability of sanded polymer, though excels with many grout types. You’ll pay $480–$600per regrouted shower with these tiles. 

  • Glass tile: Glass tiles are extremely common in and around showers, and they do well with either sanded or unsanded epoxy grout. As a matter of fact, many glass tile manufacturers recommend epoxy grout. As this combination is on the expensive side, you’ll pay $500–$800 per shower

  • Polished or honed stone tile: Stone tiles are certainly gorgeous, and they work well with unsanded epoxy or polymer grout. The price is right here, as you’ll pay between $400–$600 per shower grouted

  • Mosiac tile: This tile type makes for a unique and showstopping look that does well with sanded epoxy. As such, the costs here are on the high side. Grouting with mosaic tile costs $960–$1,280 per shower

  • Tumbled marble: Marble of all kinds make for great bathroom tiles, due to the material’s overall durability and fantastic array of design options. Tumbled marble also does well with sanded epoxy and grouting is rather expensive, at $960–$1,280per shower.

You’ll save a good chunk of change by DIYing your shower regrout, but take note: it’s extremely time-consuming and labor-intensive. A 25-pound bag of grout can cost anywhere from $10 to $65 depending on the type, plus you’ll need a few other tools to get the job done.

Removing the old grout is the most difficult part of the process and might take around four times longer than installing your new grout. But if you’re only spot-fixing cracked grout, it won’t take nearly as long.

You have a few different options for grout removal tools. These include:

  • Grout rake: $10–$15

  • Oscillating multi-tool: $40–$150

  • Rotary tool: $25–$70

  • Reciprocating saw: $30–$80

A grout rake is the most affordable choice, but there’s a catch: you’ll have to spend more time and energy to make it work. Aside from that, here are the other supplies and materials you’ll need:

  • Grout float: $10–$15

  • Large heavy-duty sponge: $5

One more word of caution to prospective DIYers: Even with the most top-of-the-line power tools, you’re likely to have a hard time removing all the old grout in your shower. One overly ambitious grind could crack your tile, so always exercise the utmost caution. If you’re at all uncomfortable, call in a local grouting pro to finish the job.

Shower Grout Cost Factors

Labor, materials, and the state of your current grout will be the biggest factors in the cost to regrout your shower. Here’s more info on how these play into your budget.


On average, you’ll pay between $10 and $25 per hour to have a professional regrout your shower. While this costs a lot more than doing it yourself, you’ll save yourself a lot of time and hassle. You’ll also save your shower tiles from potentially getting damaged. 


Different types of grout vary widely in pricing. Your standard cement-based grout comes in at the lowest cost, while polymer and epoxy types will go for significantly more. However, polymers and epoxies tend to last the longest, so you’ll get your money’s worth.

Full Shower Regrout vs. Touch-Ups

Depending on the state of your current grout, you could pay more (or less). If you don’t have any serious damage to cover, you might pay as little as $1.70 to $5 per square foot. This would cover a basic cleanup job with some “spot” grout removal. On the other hand, a full professional removal and regrouting goes for around $10 to $25 per square foot.

FAQs About Regrouting a Shower

What are the main signs that your grout needs replacing?

If you’ve been side-eying your grout for a while, chances are it could probably use replacing. Here are the main signs to look out for:

  • Cracks

  • Stains and discoloration

  • Cracking, chipping, or crumbling during regular cleaning

  • Mold and mildew growth

Again, keep in mind that you can do a partial regrouting at a significantly lower price point. This means you don’t have to wait until you can’t stand the sight of your grout—you can get a quick refresh without breaking the bank. 

Can you put new grout on top of old grout?

Unfortunately, this won’t work. Regrouting requires a smooth surface in order to fill in cracks, so you’ll have to remove the old grout first.

How do you clean shower grout?

The best method for keeping your grout clean depends on the level of staining and/or discoloration. For light cleaning, use warm water and a stiff brush (hardware stores carry brushes specifically made for cleaning grout). 

Tougher jobs call for a 1:1 solution of white vinegar and water in a spray bottle. Spray the area down, wait for 5 to 10 minutes, then scrub away with your grout brush. For even more cleaning power, add water to baking soda until it creates a paste, then apply this prior to giving it the spray-down with vinegar. If the mess is too much, you can also have a local tile and grout cleaner take it on.
