Your "below" picture is a custom fabricated shower enclosure from a local glass shop. They can have one fabricated in just about any configuration you can come up with (within reason).

Doors should hinge off a wall. And that’s where the controls should be located. For anything but the simplest single shower door, always use the custom glass shop. It’s a false economy to try to get some yahoo to install stock, when more than half can’t build to the standards needed to use stock.

Millworkman, I guess doors are usually on the longer side. I contacted 3 glass companies to get quotes. Thanks.

Live_wire_oak, especially where I live. I know to attach the door to the wall (and put studs in the correct place) but I am amazed at how many doors are NOT attached to the studs. I have been looking for two days, and there are many doors that do not attach to the studs. We are already planning where to place support for grab bars, too.

If I can find a 48" fixed wall panel, I think I can use the 33" pivoting bifold door attached to the 36" side of my shower base. Controls by the door.

Could I put the shower head on the 48" tiled wall where the water would splash on the 36" tiled wall and the 48" glass wall? If so, very little would splash on the 33" bifold door.

It is probably a bad idea though...

"I contacted 3 glass companies to get quotes. "

Are they coming to measure? You can order a fixed 48" panel from a glass shop but it is definitely not a DIY install or a GC install. It needs to be installed by someone who knows what they are doing with large pieces of glass as will as drilling into tile and the pan as well as hanging the door. They all need to be prepped by the glass fabricator to be used together. You do not buy a panel here and a door there and put them together. All prep work must be done before tempering and nothing can be changed or modified afterward.

You're going to have an issue now that I see your picture. The fixed panel will be custom thru a glass shop. Bifold shower doors are Box Store Homeowner products predominantly. I do not see how you will get a self respecting glass shop to use a bifold shower door form a box store.

No way would I attempt to install the glass, but my GC will have to install it. They will measure once the tiling is finished.

I think I can use a 48" fixed panel with a brace/support, and not even have a door on the short side. The water would hit the glass. Is that a bad thing?

Or do something like this with a bifold door in the front and a fixed panel on the short side.

Onyx base has a dual threshold on two sides. Threshold is about 2"-2.5" wide so there should be plenty of room for the glass and frame. This glass enclosure is 33.25" x 46". There will be about a 1 7/8" gas between the folding door and the 90° back fixed panel. I guess this is semi frameless.

You need a custom glass shop. Period.

Yes, that is why I called three yesterday.

"but my GC will have to install it"

No way, should not even be a thought.

Your GC is out of his lane. His role is to supervise the specialty contractors like glass providers, tilers, stone fabricators, electrician’s. His role is not to touch any of that. Are you sure that you are dealing with a GC licensed as a GC and not as a handyman? There are different licensing levels. Check with your state database. And his insurance company. If he’s performing work outside his classification, then you are not covered under his policy.

Your GC should be calling the glass shops that he has a prior relationship with. For them to do the job. Not him. If he doesn’t have that relationship with subcontractors? Um, he isn’t qualified to do the work.

You shouldn’t even be in this. Other than for design, that the pros have to overrule as undoable. Since you won’t pay a design professional to advise you.

ProSource Memphis and millworkman, not possible. It really doesn't matter if you think my GC should install or not. I said he will install because there is no one else. I have to explain my area's lack of experts on every post, and I didn't this time.

Maybe people are not reading posts...just reading the last one...Tired of explaining. It does no good to criticize who will be installing. I appreciate any helpful criticism. Until you have lived in my state, you would not believe the lack of experts in my town. Sad, really.

Well then good luck. I am sure it will turn out perfect just like all the other custom shower enclosures that you GC has installed.

If it’s within the distance for the contractor to drive and pick it up, then it’s within the distance for the glass shop to template install”Measurements” for this are a no go. Template required. Most true custom will travel up to 250 miles with a trip charge involved. Get the glass shop to do the measure and install for that design.

Or you design something simpler, with a bigger margin of error, for your guy to install. This needs the door hinges at the wall, no matter what! You don’t design outside the capabilities of the materials parameters or the skills of the contractor and expect it to work and not leak. That design is not at all friendly to anyone but a custom glass install shop.
