The floor was installed over Hardibacker underlayment. The shower was installed with Schluter Kerdi waterproofing membrane over the top of the drywall. Another example of how Kerdi can be used in various applications.
There will be a free-standing vanity installed next week with a glass top and sink and I will install a backsplash around it with the listello band and bullnose. I will add photos of the completed job as soon as it gets installed.
Here are some before and after photos of what is finished now. You can click on any of the images for a full-size version.
Update: Here are the photos of the completed bathroom with the vanity and backsplash installed. The vanity has a one-piece glass top and sink basin, very nice!
