showersliding-glass-door
I have an unfinished stand-up shower seen in the picture. I got estimates for frameless glass (a look that I like) and all of them were in excess of $3000. If I give up the idea of it looking super nice, but refuse to have a shower bar with a curtain, are there good economic options for finishing it off? Anything pre-fab that can be adjusted in the field?
Thanks!
The answer: Swanstone
How I found it: I got lucky. I just grabbed it and started taking it to local big-box places (I assumed it was a big-box as the materials in this house aren't necessarily 'high end').
I stopped at Lowes and the initial guy in the kitchen section had no clue, but I was fortunate that a curious co-worker popped his head over the counter, thought for a minute, then declared it 'Bermuda Sand' from 'Swanstone'. We found the swatches and, sure enough, he was right-on. So kudos tot he very helpful Lowes employee.
Apparently, these type of shower systems are just large panels of solid surface material that is glued up on the wall. They idea is that the panels abut, then caulked. The corner cove is more of an 'extra' piece that can be used if desired. The underlayment SHOULD be your standard tile surface...water proof cement board that is then sealed with some sort of water sealant. However, I don't know that in this case, so this particular piece seems to be a rather critical for my shower. So, glad we were able to find it.
The challenge for future people reading this is that I guess the solid surface companies are many, and the patterns all tend to be unique to each company, so it is a bit of a needle-in-a-haystack hunt trying to find these.
For contractors, I'd like to suggest leaving a note on the inside of a bath or kitchen vanity with the manufacturer's info. That'd be handy. ;)
Joe, sorry to use the "answer" function again instead of adding another comment, I wanted to attach more pictures.
The tile I used was not available with a bullnose so I finished it flat on the sidewall. The edge cant be seen normally so I did not spend time making it perfect, but for your situation I retract my note about never finishing an edge with caulking. If you end flat to the wall around that corner it would be perfectly fine to use caulking for aesthetic purposes, use paintable caulk so you can paint a straight line down the whole side when you paint the wall.
Sorry I misunderstood your question, my situation was similar to yours and wrapping the tile around to the outside seemed like the best solution for me, and it looks pretty good that way (at least my wife did not complain, that's all that really matters).

IMO, not really (someone screwed the pooch with that mirror). TL;DR: it's curtains for you, or bust ($$$).
If I had to guess, any type of custom shower door is going to cost $1~2k installed. So, you should get some estimates and see where you're at. If they all want 2.5k for glazed doors, why not go all the way and get what you want? Perhaps one of them will do some sort of financing?
Take some really good measurements; you might be able to squeeze a complete door set behind that half wall, to make this a feasible DiY project (but that will probably lead to a mold problem).
ATM, my town is in "construction season" (summer); wait for winter to come around and everyone's prices should drop. Use a curtain in the meantime, or at least until you can secure a reasonable bid.
As I understand it, cutting tempered glass is basically out of the question. So this is either going to be full-on custom, or ad-hoc schlock. You've literally backed yourself into a corner here. (who put that mirror in?)

Good luck with that!... I sincerely doubt you have a 6' oven.
There are several different types of corner shower doors that come as kits. Using 2 out of the three panels (and a small filler strip of 'C' channel if necessary) might do the trick, but you'd better measure everything extremely well...
Good luck in your search, these days "adjustable" means it can be ever so slightly out of plumb, and still hang frameless doors. To the best of my knowledge, no one sells a glass door with actually 'adjustable' (non-glass) side panels but someone might.
I have seen accordion style (folding) plastic (PVC) shower doors; the hard part is going to be finding one that has a track that will fit your angled base, and then you would 'simply' cut it to size. Or just get a straight one and modify it.
