Thankyou therenee...my parents really love the shower...I came up with the in-wall cabinet idea when I remodeled my small bathroom in my home. I even made a recessed towel rack on it because the bathroom was much smaller...it looks like this: At my parent's home, we put in a 2x6 wall there instead of 2x4, to have more usable space inside the cabinet...at my house, I still had more room than the newer homes, because of the old lumber that really was 2x4 and because we went with a little bit thicker sheetrock (5/8) on that wall to help with sound insulating

Most manufacturers recommend 100% silicone bath and tile caulking in corners. ( no grout ) I have had great results with epoxy grouts if you can find your color selection. A bit more labor intensive but well worth it. Check with a local tile distributor. Difference between sanded and unsanded. For residential applications, siliconized latex is more than sufficient. As for the epoxy grout, it's my opinion that with a few specific exceptions, in residential installations, it's expensive overkill. As for differences in the grouts, those of you who aren't familiar with them, you can check it out in the FAQ's on the gallery side of this forum. As for Colorfast and Mapei, yes, I'm familiar with both of them, and the only times I've ever had problems with Colorfast's caulkings was when it was old. I've yet to ever see what I'm seeing in the pictures up above.

Well, you could try a steak knife.... :-) (just kidding-- For some reason, Ron White comes to mind!) Either with a wet saw or a score and snap cutter, if you have one.

is it necessary to use the pre-treat cleaner or IF the grout is clean can I go straight to the colorant and still achieve the same benefits? So long as all you have left is staining, and there's no grease or anything else that would inhibit the bond of the colorant, then yes, you can go straight to the colorant. Is it true my grout will be as clean as my tiles after routine floor cleaning. It should be, yes.
