StoneMar Natural Stone Company LLC The advantage to stone is that the edges can look finished once the tile is all sealed--with porcelains you will usually need to use some kind of profile because even through-body porcelain can sometimes appear unfinished on the edges. We use this method a lot for a super clean modern finish, as Joel accomplished here. (Loving that rug, by the way)
I love the space and design of this bathroom but do not care for the mounting location of the glass clips on the floor. Far to often these clips are the result of a failure point in a showers waterproofing system.
It can be done with great care or with proper planning but make sure it is discussed and the proper fastener length is worked out!
