If you are talking white grout IMO it will still get dirty and need claning just a bit less often.

In my experience with it, it gets dirty over time, but the dirt stays on the surface, so it scrubs off easily and looks like new. With regular grout, the dirt gets ground in/absorbed, so you can't get it clean again.

My marbke tile has 1/16 grout lines and it's slightly shiny. Isc that epoxy grout? It's been GREAT - after 22 years, no accumulated grime or scrubbing needed. I want the same for my new house, so want to know what it is. Is it epoxy???

Here is my experience. I have my original 50 year old bathrooms with 4x4 field tile with small spacing (my best guess is less than 1/16 inch - we had to scrape by hand with a utility knife) and the hall and primary needed to be regrouted. We did it diy and neither of us had ever done this before. My husband did the primary by himself (removal of grout and regrouting) and used spectralock epoxy. I did the hall bath by myself and used mapei unsanded with the sealer additive. i was out of town when my husband did the primary but he said it was a pain and it is already yellowing and staining. for the hall bath only the caulk has stained and its been more than a year. i would go with mapei hands down when we eventually renovate. and both baths are used at least twice a day for showers.

I have 12 year old epoxy grout in my shower and I love it so much! I have untreated well water, so get a build up of that orangish mold once in a while. I spray the shower with a cleaner that contains bleach, let it sit for a bit and rinse it off. No scrubbing needed, ever. No color change at all (it's not white, however). I just had a new bath remodel and they used epoxy because I insisted. I'll never choose anything else.

Epoxy yellows. It is complete overkill for residential anything. The new polyurethane, acrylic, or resin fortified cementitious grouts, do not have the issues that epoxy has, and are nonporous.

Staying clean is up to the user however. Dirt wont soak in to porous grout. It will sit on the surface. Dead skin cells, shamppo and soap residues, do not cease to exist because you upgrade the grout. You still have to squeegee after use, and scrub occasionally.

Bleach is bad for grout of any kind. It is harsh and breaks it and caulking down. Ventilation is better than allowing that normal crud to stay wet enough to form mold and mildew. Because that what it girms on, if it stays wet. Because it’s the staying wet that is THE issue.

According to The Tile Council of North America TCNA:
"Cementitious grout, as you may have observed, is porous - it can absorb a
stain. Looked at under a microscope, there is a large surface area to
absorb stains. For this reason, many owners choose to seal their grout -
usually the better the sealer, the more the grout joint is protected.

Even better, if epoxy grout is used, it is virtually as stain proof as
the tile.Epoxy grout (meeting ANSI A118.3) is quite different from cementitious
grout and epoxy emulsion grout. Made from epoxy resins and a filler
powder, the grout is extremely hard, durable, and nearly stain proof.
Often times the bond between tiles is stronger than the tile itself."

I forgot to mention - I've NEVER had to seal my epoxy grout, unlike sanded/unsanded grout. I always roll my eyes when people say tile is easy care - they forget to mention that the grout is a nightmare, unless you use epoxy grout. Otherwise it's a constant hassle.

Mine was a light gray and with on going construction I am not sure if the workers tracked dirt down in it or what, but they look dirty and I am sure it is stained because I have tried EVERYTHING- and I mean everything to clean them and nothing has worked. I really wish I had gone with regular grout

I grouted a shower floor with epoxy over 12 years ago and it was fine until I started using Method Daily shower cleaner. The acidic spray started to loosen the top layer of the epoxy and I'd find grit on the floor. I didn't put two and two together for a while. BTW, the shower spray also seemed to cause blooms of red/orange mold which I'd never seen before.

I used urethane grout this time. The directions suggest the use of bleach products to clean. No vinegar or acidic products though.

We used Laticrete epoxy grout in all our tiling. I looked up the ingredients of the sachet of power used to clean during installation and remove grout haze. 100% citris acid. So I wouldn't suggest using a citric acid based cleaner (of which there are many sprays on the market) to clean regularly or could affect the surface of the grout.
