I tried every suggestion in this post and nothing worked for me. I live in New Hampshire and it makes sense stains will be different depending on where you live. Finally, I found the solution ...a pumice stone. There are several brands available online. I found this one in my local grocery and hardware store, and it's pretty inexpensive. Just use with water ..it didn't take a lot of muscle....just a little patience but it worked beautifully. I had gone so far as to get a quote for replacement shower doors and stumbled on this product just before I was ready to place the order. So glad I tried it because new doors were more than $800. Just wanted to share in case it helps someone else!

I ordered the EdFred glass shower cleaner shown on Muchfun's link and tried it. It took a lot of elbow grease and I had to go over the shower door and wall a couple of times. Applied it with a Scotchbrite pad. I can't believe it actually worked. It was 10 years of hard water build-up. I tried everything imaginable to clean it and nothing worked. I even tried, over the years, using a razor blade to scrape it off and that didn't even work. I will be applying the Rain-X today and hope I can get DH to wipe down the door and wall after showering. Will also get some shower gel or use liquid soap. I sure hope that is the end of this very vexing problem.

Hi there, This is my first time posting in the bathroom forum (been hanging out in the appliance section), so I'm glad people have the same concerns I do about cleaning the shower! Apologies in advance if this is a bit tangental, but I've been looking at various shower surfaces for our new bathroom remodels. I like the look of tile/stone but absolutely abhor the idea of dealing with the grout and caulking -- it just seems like an inevitable problem. Those acrylic inserts appear to resolve this issue, but they're just so cheap feeling I don't think I can buy into it. Having recently visited a home show, I think I found a really interesting compromise called stonecraft (not sure if that's just the company brand name or the actual product name -- linked below). It's a plastic/cement mixture that they paint in two layers. The first layer goes on solid. Then they 'tape' the tile pattern you want, then apply the second coat (different colour). When the tape's removed, the first layer appears as the grout lines. I first looked at this for my patio deck, but the more I read into it, the more I liked it for other parts of the house -- including the shower (they even suggest it). My contractor worked on another house that used this outside and it really feels like a stone material. As it's painted on, it should be seamless (walls, floor, ceiling)and, therefore, a breeze to clean! Kind of hoping someone's used this and can share their experience, because it seems like a silver bullet. As for the doors itself, I'm wondering if anyone knows how long a shower stall would need to be to go 'doorless' without getting significant splashing out of water.

More notes regarding setting drain depths... once the rough plumbing is run under floor, whether its a raised floor or slab, the maximum drain depth is set, as slope from the sewer tap to the drain has limits. The installation of the actual drain fitting is subject to those previously set limits. Its really important to PLAN AHEAD. Curbless showers are still getting introduced into the market. I have one in each of my current homes underway, but only in the master. Installed my first over a decade ago for wheelchair access. Costs more to do. Cannot always retrofit as it requires lowering the entire drain system under floor 4". Linear drains cost more to do. Etc. Anything that doesn't cost more would show up in production homes.
