With a sleek, minimalist design, oversized rollers for best-in-class sliding action, and low-maintenance CleanCoat glass treatment, the shower door combines bold style with delightful functionality. Because this product can be installed to open from the left or right, it fits easily into your bathroom layout, and 3/8" out-of-plumb adjustability on each side makes the shower door easy to install. A large range of sizes, glass types, and finishes means there’s a shower door waiting for you.
This door really elevates my fiberglass shower insert.
I’m glad I had some professionals to install it.
Beware it is tempered glass so please use foam to rest it on while installing because my contractor had set it on the tile and one of the panels shattered. So they had to order a replacement from Kohler and when it got here, the manufacturer had sent out clear glass instead of the frosted, so I’m using this this matched in the meantime while we wait for another replacement. 
I do love the frosted glass as it adds a bit of privacy, and still lets in light, and hides all of the shower clutter. . Twigforeverhome. MI. Thu Dec 28 2023
