Look for pieces called "quarter rounds". They DO make them in ceramic. I would still suggest caulking that corner, but the 1/4 rounds will hide it, and make it look alot cleaner.

Janesylvia, I have a bathroom with a corner shower unit that (in a small space), and when installed, I opted for a door that swung both ways. This was done 5 years ago, and it turns out that the door leaks through the vertical gap, although not a ton. When I recently remodeled my master bath, I had the glass installer (a different company from the other bathroom), install a vertical strip on my corner shower unit, making the door open only out. This seal has stopped all leakage of water. In my limited eperience, it seems the vertical gasket or seal is much more likely to keep your shower from leaking. It was a little frustrating to always have a towel over the bathroom rug to absorb leaking water from the shower. (in addition to concerns over continual dampness on the floor)

32 x 32 is a little small. 70" is pretty substantial and you may want to consider putting in 2 shower heads, etc. and make it a 2 person shower. 39 x 39 isn't huge but I thin 36 x 36 is about the minimum you would find comfortable.

I need to install a 36" or so shower in old construction. I like the looks and general simplicity of this unit (includes thermostatic control/glass and door, plumbing etc) and wonder if there is anybody out there who has used any of these units: My plumber tends to not like things that are new to him (I don't blame him) and I am hoping someone has installed this and it's as easy as it seems. I can't link the page directly but it is the Advanta Camry three piece unit, bottom right on the linked page. Thanks in advance! Here is a link that might be useful: corner shower unit from Costco
