Kohler K-9136-BV Square Tile-In Shower Drain in Vibrant Brushed Bronze - Perfect for Modern Bathroom Renovations & Luxury Shower Installations

I purchased this for a custom shower install using square mosaic tile for the shower floor. This is a truly square drain, making tile cutting and placement much easier. Additionally, the drain frame is about ¼" thick (more or less) aluminum or stainless, with a removable and replaceable grid insert (also thick). This is more expensive than the Home Depot & Lowes stamped sheet metal drains that are round (even if you use the square cover). However, it is worth it for the much higher quality and longevity it offers.The lower assembly is gray PVC of standard pipe sizing. My install was onto an existing standpipe already set into the concrete basement floor. I only needed the upper assembly, and was able to simply unscrew this portion and mate it to a gray PVC adapter (electrical conduit to allow full threadding capability). This allowed me to easily set the depth and square it up by twisting it.Once set, the gap was filled with thin-set and sealed.5 stars for this being of much better quality and style than the typical drains out there, and for its versatility.
