I have gotten alot of inquiries into the tub shields that I use in the stores. Here is some information. They are from MTI (mtiwhirlpools.com) and we purchase them through ferguson. They start around $800 and go up into the thousands. They are clean and classy- and can create illusion of more space because they are glass.
The two I use the most are:
Nordic Series- with one fixed and one hinged panel:
The Solo shift- one single hinged panel:
These are some other MTI glass enclosure that I like:
They are available in different finishes. I would recommend professional installation.
