Hi all, I have a sad story to share... I am a DIYer, but last year my wife and I decided to hire a professional to redo the main bathroom in our house, because we thought it'd be nice to have a pro result (unlike, for example, the kitchen that I re-did, which looks pretty good to most people but I can easily point to 10 things that aren't 100% right). So this pro finished the job about 11 months ago, and I can easily point to a dozen things that aren't 100% right and *obviously* wrong. Most of it is aesthetic (e.g. major lippage in floor tile and wall tile), but over the past several weeks I've been seeing something more troubling... The photo below shows the section of wall right next to the shower. Over the past month or so, I could see bubbles forming underneath the paint, clearly a water issue. I thought the issue was related to water which was dripping over the edge of the tub right there, so I though OK I'll just install some kind of guard in order to keep the water inside the tub. So I scraped all the failed paint away and installed the guard. One day later, I snapped this photo right after the shower was used, and it can be clearly seen that the wall is wet again! But the guard was effective, too, so the water must be traveling behind the tile from inside the shower to that wall right outside the shower. I'm here to ask for advice about this situation. What does this look like to you, and what does a solution look like? Thanks in advance for your input. [attach]104352[/attach]

I plan to install my 3cm thick quartz countertop this week. It is roughly 3 feet by 4 feet and will be sitting on top of my kitchen island base cabinet (pictured below). My first step will be to place the countertop on the base cabinet without silicone and get it in the exact desired position. Then I’ll trace an outline on the bottom of the quartz. I plan to put painter’s tape along the outside of the top of the cabinet to catch any silicone from getting on the cabinet. I’m using 100% silicone transparent MONO Kitchen & Bath Sealant (product link below) to adhere the countertop to the metal strips on the base cabinet. My original plan was to use PL construction adhesive, however, the cabinet installer who I’m purchasing the countertop from assures me that 100% silicone is best for this type of application and it’s all he ever uses. It's also been recommended for use in this application by members of the Doityourself community in an earlier post. Once I apply the silicone I will have three people holding up the countertop while a fourth person looks from below to give direction on correct placement. Once we’re in the correct spot we’ll lower the quartz on to the cabinet and let it dry for 3-4 hours. I’m just wondering if I’m missing any steps or if anyone has any suggestions I’d love to hear them as I’m hoping this DIY goes well. Thanks!
