I have a frameless glass by-pass door for my 60" wide shower. Well, there is an outer frame that holds the two sliding pieces of glass, but the glass itself has no frame. I just measured it and it's a mere 3/16" thick. It's been in daily operation for 9 years. We bought the shower door kit from a local independent home improvement store (later bought out by HD). My BinL was carrying one of the doors in from the garage when there was a loud boom. He swears the glass didn't flex and he didn't bump into anything. Fortunately he wasn't hurt, but I found pieces of glass for years after. The store replaced everything and no problems since.

DIY is a great idea. That is pricey. From my experience, local retailers can get double or more than what you can pay for the glass on your own. You can buy over the internet and have the glass shipped. They will crate it up. I just bought a 3/8" - 46" french door set up for $800 on ebay and it included 4 hinges and 2 handles. Just make sure you take super accurate measurements (ie. you cannot take a tape measure across the opening and bend it at the far edge). If your walls are not plumb, the glass can be cut out of square (unnoticeable to the naked eye) to keep gaps along the walls even. Just take a long level and make this determination. The seller should provide you with a measurement sheet so you can record your measurements in the opening. The manufacturer will size the glass accordingly. Regarding installation, not very difficult. The single most important advice is NOT to bang the corners of the glass, this is their weakest point. Just a slight direct bang to the corner can shatter the glass. Once installed, they are fine..they just need to handled carefully. I would recommend renting or purchase suction cups to assist with moving. The frameless doors are worth the investment. All those track and caulk issues go away. If you keep up with basic glass cleaning/maintenance, they always look great. 1/4" glass is also fine. Like anything, there is always better and more expensive options. The 1/4" in noticeably lighter. 1/2" is overkill and would never use it. 3/8" is the best choice, but your budget should be your primary concern in making the choice. Try ebay...If you cannot find one your size, call them.

HI-I know this is an old thread but I am searching for a company in Pennsylvania to fabricate and embed the a 3 sided glass shower enclosure with one door into the granite sill. I have not found any who will take care of creating the channel in the granite. So many opinions from different installers!! "exposed channel is cleaner looking" "clips are cleaner looking" "exposed channel will pit" "clips will get mildew in the silicone" "recessed channel will get dirty".....I am wondering how liamrperry's shower glass turned out? Any problems?Thanks.

You can use a tension/pressure shower curtain rod that is easy to install and easy to replace. You can get a straight one or a bowed one that makes the shower area a little larger. https://www.amazon.com/TEECK-Adjustable-Stainless-Anti-Slip-Drilling/dp/B07VDXYK38 https://www.bedbathandbeyond.com/store/product/titan-trade-stainless-steel-dual-install-curved-shower-rod/3331801?keyword=shower-curtain-rods
