Plus it's embarassing when you have house guests.
This past weekend I installed epoxy shower grout in between our 2 x 2 inch shower floor tiles.
With a little help from the tecnhical support line of the company that makes the grout I was able to do this project in less than 2 hours (that includes prep, install, and cleanup).
And I was a little under the gun since it was 7 pm when I started, primarily because I put my daughers to bed at night :)
If you want grout that never needs sealed and does the best job at resisting stains & mold this is the way to go. Since I'm in the rental home business this was a test run to
1. see if it was hard to install
2. examine the durability of the product
Well I'm here to tell you that you can put your fear aside when it comes to installing this brand of epoxy grout (the brand is CEG LIte). It was easy.
What makes it so durable is the fact that it's practically impermeable to water. Sanded and un-sanded grout have pockets within their physical structure that can allow mildew and mold to grow. This isn't the case with epoxy.
The working time is 40 minutes and I think this is what freaks people out, especically if you have a large floor. Our shower floor was only 32 by 58 inches. I set a timer for 30 minutes so that I'd have a 10 minute warning and be able to stay within the epoxy's setting timeframe.
If you're installing new floor or wall tile I highly recommend looking into epoxy grout. In case you'd like more info, pics, and a video (yes I grew my NHL playoff beard early, GO PENS) visit my blog post at http://www.homerepairtutor.com/shower-grout-...
