I have had great success using 100% colored silicone caulking in showers. Even though it may eventually get moldy it will usually last 3-5 years if they clean their shower regularly and properly. Grout I have found will continue to crack sooner than that and create moisture issues. 

You can check out the caulking & colors at the following link: http://www.custombuildingproducts.com/products/grout-materials/caulk/commercial-silicone-caulk.aspx

Over time all caulking grout in a shower is going to get mold. That because the caulk to coming loose from the areas. Grout will crack within a year or less and the customer continues to use the shower than the shower pan fill with water and you have a larger problem.

The problem with grout it will not bond to the finished edge of the tile there fore is doomed to fail.

I agree with you Hector, that looks like a crack from settling. Now that it has, just regrout it. Caulk will fail or get moldy in that large of a joint. When you apply that much caulk it will shrink noticeably. It is not designed for large gaps.

Hi Stuart

 

I have fix these problems in the past.

1st never use caulking in a shower floor. It will always turns moldy.

I would cut the caulking and grout out. Clean the tile if needed. Clean the grout if needed.

Dry the shower with a dehumidifier 1 to 2 days with a fan, check and see when the mastic dry by eye sight. If dark gray it will turn light gray.

Measure the amount of water coming out per day in a 5 gallon bucket make black marks on side of bucket for seeing when it dries out.

After its dries out match color of sanded grout with color chart bar chip set.

Mix grout with grout harder and install and wait 2 days for grout to cure. Seal on the 3 day and get paid.

 

I charge about 450 to 1500. for this type of repair sometimes more depends on time spent.

I try and charge about 150 to 175 per hr for this work

Hi, partners,

 

The attached are photos of a shower floor joint where it joins the wall.  It appears that the caulk is coming loose in the corners. What is the best way to remedy this problem, and to keep water from penetrating in these areas?  Grout, caulk, both? Any methods or products that do better than others?

 

Thank you,
