It will be harder to remove at this point-but paint stripper will do the trick however in a closed area with no ventilation it is dangerous as paint strippers are toxic. Green paint strippers may be better but not as effective. Let the folks who forgot to wipe it remove it . If they cant hire a stone refinisher-he or she will remove it safely and deduct the charge from your installers. Just for your info-sealing grout lines in a shower stall IMO may not be that effective. Sealing it from what-I know but think about it what would stain the grout on shower stall walls. If you dont have to many parties and bbq's in there I think you will be fine without it !!. Most grout issues in shower stalls are from aging and discoloration of lighter colors. Nothing a sealer will prevent as its only performance is to temporarily inhibit the intrusion of staining agents. Sealer companies make a big deal about sealing everything. While I do believe there are indeed surfaces that require sealing I want to be informed as well as informing my clients when and where a sealer may be needed based on each application. I like to look at things somewhat logically and not follow the herd because someone said we had to do it.

I like the matchy grout. Here is why: Autumn dot 4's kitchen is by far, my favorite GW kitchen and I do not handle change very well. Seriously though, instead of envisioning just a backsplash, look at your kitchen as a whole. The tiles themselves are unique and gorgeous. There is no need to individually define each tile. With 2x6 tiles, that will be a lot of grout lines. I think you need to go subtle. Do I love the inspiration picture? Yes. Do I think that would work in your kitchen? Yes and beautifully so. I just think the other is better. Disclaimer: I have gone terribly wrong with grout choices in the past so you may need to heed the advice of the experts and ignore mine.

Yvette Im sorry your upset, It does look lighter in todays photos to me. You have very poor photo quality and in truth you are comparing a Showroom floor with white marble or glass contrast relfecting and a complete different lighting schematic to your tub alcove. There is some solice in lighting. This is repeated on these forums time and again. Stone itself comes in dye lots and VERIES drastically. Stone wicks moisture, from thinset substrate and grout as it cures it gets darker before it lightens. Some thinsets can take 30 days to fully cure, some portland grouts do normalize over 7-10+ days. and there is a dozen things that can go wrong with hand mixed and installed grout. I cannot see close enough the details of your install but I can tell you I have had to watch sales people at tile shops like a hawk in that they are usually not a person to take advise from. Can you be 100% certain they sold you the proper color/brand or did they sell you something similar to sell you something. ? You should have more recourse if you Payed a tile professional to source and purchase the materials themselves grout included and if you have a contract and stayed hands off. One thing homeonwers dont consider when they get involved with these things is the importance of putting all the liability in the contractors hands to afford recourse. People that do the shopping finding deals choosing materials, and then hiring labor have little to no recourse so i hope thats not you.. I suggest further patience and see how it lightens, play with lighting and start to focus on other aspects of your room..

Just match the grout as closely as you can to the tile color…so a taupe-gray. I agree, counters are stunning!
