This glass partition between the bathtub and the shower is slumped glass. It was done by a glass studio in Phoenix, Arizona, that is no longer in business. I recommend you search for glass artists in your town, most of them are familiar with the process. It basically consists of placing grids and rods under a slab of glass, which is in turn heated at high temperatures to melt and slump the harder surfaces and then it is slowly cooled to avoid cracking. I'm glad you like my work, and please vote for us for Best of Houzz 2013. Thank you.

Thanks so much for your reply! Beautiful work.

Thank you Adernburg! Please take a look at the Dining Room in the same album "Southwest Contemporary" you will see how the same materials is used in a different space, with different proportions.
