1) After showering, the off-white colored grout turns into a gray color in small patchy areas. Once the shower dries up these patches fade away and look normal. Should I worry about this? Why it happens in patches, unless you sealed it with a non-breatheable sealer and didn't do a complete job, I don't know. But conventional grout SHOULD darken when it gets wet, and lighten when it dries. 2) The grout on the ceiling tiles seems to have shrunk. It might be on the verge of cracking in some places--I'm not sure. The white edges of the ceramic tile are slightly visible in some places. You might just be noticing it now. Once grout dries (within the first 72 hours) it won't shrink any more (not measureably, anyway). Let me ask you-- was it sanded or unsanded grout that was used, and how big are the grout joints?

I've just purchased two Hansgrohe showerheads, one from their regular line and one from their Axor line. They have a bunch that are contemporary styles which would go well with that faucet. Are you sure you don't want one showerhead to be a rainshower, though? It only needs to be about 6" down from the ceiling, so unless your husband is more than 7'2", it could work for him, along with a handheld on a bar you can adjust up and down. We purchased the Axor Downpour 10" rainshower head, which I think is beautiful in its simple, clean, polished lines, a Hansgrohe Raindance S 150 Air as the handshower, and the Unica S wallbar. -- Eric

Maybe I'm not understanding properly... Either you have water from the shower dripping down behind the cover plate, or you have a problem with your plumbing. This sounds like more than just the first scenario. I'd try taking the cover plate off and poking around inside to see if there's anything obvious. It could be a leak starting at the showerhead and working its way down. It could be the mixer unit. I'm a big fan of diy, but if you have to replace the mixer unit, you might be better off bringing in a plumber. If the wall behind is accessible, I'd suggest you make all your major excavations there (and maybe put an access panel, if it's an option). You can save money by doing all your drywall repair yourself. If you do the plumbing yourself, get a good book or two and have a couple of buckets of water pre-filled in case you set your wall cavity on fire.

Well I'm just a homeowner, I would scrub out the area where things are missing, use a scrub brush or old toothbrush if you don't have scrub brush but you need a scrub brush since you are worried about your family's health, the mildew in the grout is not good for any of you especially if you have allergies, So fix the broken area by cleaning it out as good as you can, I'd use comet since it has bleach & maybe buy a mildew remover(smell strong) tho they are only good for about 1 time & basically they are bleach so might work better to use bleach & save your money, can pour a little bleach in small container & dip your brush in & scrub that area good, wipe out with old washcloth to remove all bleach or Comet(do not use together-chlorine gas can kill you) when area is clean & dry use a tube of bathroom caulk, comes in a soft tube,5.5 oz last time I bought it- cut the tip at angle & cover whole area & lay your pieces in way they should be & press down until even with the rest & way it used to be& wipe away excess caulk & clean off tile, leave it to dry for 24 hrs. This should take care of that problem but you should use the scrub brush & try to remove some more of the mildew, once off if you wipe down shower after using it it cuts the problem down greatly. I use Dap Kwik Seal, it at least can be removed if necessary as some ruin area around your tub or shower, becomes like plastic & no way to remove it but remove the tub or shower & start over DD had that mess. Good Luck & this should last until you move . Save rest with the tip cap on in case anything else becomes a problem, it will last a long time. So will cost about $5 or less to fix! If their are other areas where grout is out, fill it in. Be sure to use same color grout as is in there comes in white & almond & I think your grout is white but take a good look so you get the right color, it is not hard to do. Hard part is getting gunk out of that space as soap & mold will not allow the caulk to seal. Clean & dry area & it will work like a charm!! I know as I have done it for people.
