Project Spotlights

Our service team is so proud of this neo angle steam shower with ½” low iron glass with the clear shield coating. The hardware is chrome and the stunning marble was imported from Italy, just for this project.

J R Glass was asked to take a look at a project in the town of Edgartown on Martha’s Vineyard. The home was completely modernized inside with an updated kitchen, five updated bathrooms and glass handrails that lead downstairs to an entertainment space. Pictured here are three of the bathrooms, with ½” low iron glass and custom mirrors, installed by J R Glass.
