Choose epoxy grout for shower floors, family primary bathrooms, and other high-use wet areas where you want stain and mildew resistance without periodic sealing. Choose cement-based grout (sanded or unsanded, usually polymer-modified) for many floors, walls, and low-use spaces if you will seal it and maintain it. Epoxy is non-porous when cured; cement grout is porous and typically needs sealing in wet zones. Epoxy costs more and needs a skilled hand — use the compare table and zone matrix below before you add bags to the cart.

Epoxy vs cement grout at a glance
| Factor | Cement (sanded / unsanded) | Epoxy |
|---|---|---|
| Composition | Portland-cement based; polymer-modified common | Resin + hardener system |
| Porosity when cured | Porous | Non-porous |
| Sealing | Typically needed in wet zones; reseal often discussed as ~every 1–2 years in wet areas | No periodic sealer when cured |
| Stain / mildew | Can stain; sealing + cleaning matter | Strong stain and mildew resistance |
| Chemical resistance | Good when sealed; weaker against harsh cleaners over time | Higher chemical resistance |
| Install difficulty | More DIY-friendly for practiced homeowners | Less forgiving; working time and haze cleanup matter |
| Typical material $/sq ft (market estimate) | About $0.50–$1.50 | About $2–$5 |
| Best uses | Many floors, walls, low-use baths when sealed | Shower floors, high-use wet zones, dense mosaics |

What each grout actually is
Cement (sanded & unsanded)
Cementitious grout is Portland-cement based. Most residential bags today are polymer-modified for better flexibility and adhesion than older “plain” mixes. Joint width still drives the sanded vs unsanded choice:
- Sanded: joints 1/8 inch and wider — sand reduces shrinkage in wider joints.
- Unsanded: joints under 1/8 inch — smoother in tight joints; preferred when sanded grit could scratch soft stone.
Cement grout is porous when cured, so wet areas typically need a quality sealer and periodic resealing. Example outlet bags at publish: TEC Slate Gray sanded, 25 lb (~$16.49) and TEC Optic White unsanded, 9.75 lb (~$15.99).
Epoxy
Epoxy grout is a resin-and-hardener system. When cured correctly, it is non-porous, color-stable, and does not need the periodic sealing cycle cement grout does. That is why it shows up so often on shower floors and other high-use wet zones — especially dense mosaic pans with a lot of grout face. Browse the epoxy grout collection and pair it with an epoxy-rated float from tools & floats.
Brief alternatives
You are not locked into a false binary. Urethane and high-performance cementitious products (Power Grout–class) sit between ordinary cement and full epoxy for some jobs — check the product’s rated joint range and wet-area guidance. Example: TEC 550 Power Grout, 25 lb Slate Gray (~$67.99). Also see urethane grout when that path fits your installer and joint width.
Is epoxy grout worth it? (the decision)
Yes — shower floors, family primary baths, busy kitchens, rentals
Yes — for most shower floors, epoxy grout is worth the premium. Shower pans stay wet, soap and hard water load the joints, and mosaic floors pack a lot of grout into a small area. Epoxy resists stains and mildew and does not need resealing the way cement grout does (often discussed as roughly every 1–2 years in wet areas). Dense mosaic joints plus daily water are epoxy’s best ROI — Florida humidity and coastal baths raise mildew pressure, which strengthens the no-seal story. Pair the grout decision with the right pan tile in best tile for shower floor.
Maybe — shower walls, backsplashes
Epoxy is still strong on shower walls and busy backsplashes. Cement plus a proper seal can work if the owner maintains it — resealing and cleaning on schedule. Prefer epoxy when you want lower long-term maintenance or light grout colors that show stains faster.
Often no need — dry guest powder floors, low-splash walls on a tight budget
Sealed cement is enough for many dry guest powder floors and low-splash walls when budget and DIY installability matter more than zero-seal maintenance. Cement grout can also work in a low-use guest shower if properly sealed and maintained — just plan the sealer cycle honestly.
Cost: material, labor, and 5-year care
As a planning range, cement grout material often runs about $0.50 to $1.50 per square foot, while epoxy material commonly runs about $2 to $5 per square foot, with labor usually higher for epoxy because of working time and cleanup. Installed totals vary widely by region and joint density — mosaic shower floors use more grout per square foot than large-format floors.
Worked example (small shower floor, ~20 sq ft of tiled pan — planning math only):
- Cement path: rough material ~$10–$30 for the pan, plus sealer now and again (~every 1–2 years in wet areas). Example sealer SKU: Grout Sealer 24 oz spray (~$25.95).
- Epoxy path: rough material ~$40–$100 for the same pan area, often with a labor premium; no periodic sealer cycle when cured correctly.
On a mosaic pan, the “worth it” case is less about the bag price and more about years of stain and mildew fighting. For whole-bath budget context, see tile cost per square foot installed and how much tile to order (waste factor).

The install trade-off nobody should skip
Epoxy is generally a poor first DIY grout: it sets on a strict clock, and cured haze or mistakes are hard to reverse. Textured tile and dense mosaics make cleanup harder. Confident DIYers usually do better with quality cement grout plus sealer unless they have practiced epoxy technique. Hire an installer experienced with epoxy — especially on shower floors and textured faces — and use the right float.

How to buy at Tile Outlets
- Match joint width — sanded for ≥1/8", unsanded for <1/8"; epoxy still follows the product’s rated joint range.
- Pick color against samples — order tile samples and check grout charts under your bathroom light; Florida sand and humidity favor mid tones on busy floors (see the Florida grout color guide).
- Add the right tools — epoxy float for epoxy jobs; browse floats and installation products.
- Caulk at changes of plane — corners, wall-to-floor transitions, and fixture perimeters need flexible caulk, not rigid grout.
- Seal the cement path — shop sealers if you choose cement in wet zones.
- Visit or ship — Tampa, Fort Myers, and Sarasota showrooms, or nationwide shipping. Preview with Roomvo. Questions? Call 1-844-TOA-TILE.
FAQ
Epoxy or cement grout — which should I choose?
Choose epoxy grout for shower floors, family primary bathrooms, and other high-use wet areas where you want stain and mildew resistance without periodic sealing. Choose cement-based grout (sanded or unsanded, usually polymer-modified) for many floors, walls, and low-use spaces if you will seal it and maintain it. Epoxy is non-porous when cured; cement grout is porous and typically needs sealing in wet zones. Match sanded grout to joints 1/8 inch and wider and unsanded to tighter joints — epoxy selection still follows the product’s rated joint range.
Is epoxy grout worth it for a shower?
Yes — for most shower floors, epoxy grout is worth the premium. Shower pans stay wet, soap and hard water load the joints, and mosaic floors pack a lot of grout into a small area. Epoxy resists stains and mildew and does not need resealing the way cement grout does (often discussed as roughly every 1–2 years in wet areas). Cement grout can work in a low-use guest shower if properly sealed and maintained. The trade-off is higher material cost and a less forgiving install — use an installer experienced with epoxy, especially on textured tile.
Does epoxy grout need sealing?
No — cured epoxy grout is non-porous and does not need the periodic sealing cycle cement grout typically needs in wet zones. Cement grout is porous and should be sealed in showers and other wet areas, with resealing often discussed as roughly every 1–2 years depending on use and product.
How much more does epoxy cost?
As a planning range, cement grout material often runs about $0.50 to $1.50 per square foot, while epoxy material commonly runs about $2 to $5 per square foot, with labor usually higher for epoxy because of working time and cleanup. Installed totals vary widely by region and joint density.
Sanded vs unsanded — when do I still need them?
Use sanded cement grout for joints 1/8 inch and wider, and unsanded for joints under 1/8 inch (and when sanded grit could scratch soft stone). Epoxy does not replace the joint-width conversation — still pick a product rated for your joint size. Shop sanded and unsanded collections when cement is the right path.
Is epoxy harder to install / DIY-friendly?
Epoxy is generally a poor first DIY grout: it sets on a strict clock, and cured haze or mistakes are hard to reverse. Confident DIYers usually do better with quality cement grout plus sealer unless they have practiced epoxy technique. Hire an epoxy-experienced installer for shower floors and textured tile.
When is cement grout enough?
Sealed cement is enough for many dry guest powder floors, low-splash walls, and other lower-moisture surfaces on a tight budget — and for low-use guest showers when the owner will seal and maintain. Choose by moisture and traffic, not budget alone.
