It is a fairly standard procedure to not mix material types too much when tiling your bathroom or kitchen. I have recently finished a bathroom remodeling project at my own house (which made my wife very happy given that I had the place torn up for a long time and just didn’t have enough time to finish the job). Like any contractor that is on a project at his own house, the first thing I did was look through my shop to see what I had on hand that I could use on the job.
At Corvus Construction we do a lot of kitchen and bathroom remodels which naturally come with a lot of tile work. I found a few leftover boxes of porcelain field tile, few sheets of glass and marble accent tile, and some slate. With what I had already all I had to do is buy some more field tile and slate to finish the tiling job.
Since the guest bathroom I was remodeling was only 8’x5′ I decided to go all out and turn it into a luxurious place of zen that we’ve done many times for our clients.
I’ve started by installed a SunTouch radiant floor heating system. Since my house is positioned over a slab tiling the floor without a heating system would have made for a very cold bathroom floor. After all the prep work was done we installed a WEDI shower system at which point the creative part of the project really took off.
We decided to go with random 2×2 slate tile for the shower pan. While I personally am very cautious about using slate tile in the wet area (such as shower) because it can rust due to a natural high content of ferrous metals in the stone itself, however; slate offers an incredible character, color range and warmth that no other natural stone can match. 
If you decide to install slate in the wet area make sure that the tile and grout sealing job takes higher priority then the urge to start using your shower right after the project is complete.
Next I turned my attention to the shower plumbing. We decided to install dual shower heads with dual controls. The fact that I already had the body jet system persuaded me to upgrade even further to a quadruple body jetted shower.
All the tile that I had leftover, or extra really dictated the shower layout. We set shower walls with 12×12 porcelain tile, then installed a decorative boarder made out of marble and glass tile. 
We’ve incorporated 2×2 slate tile into the window trim, as well as vanity back splash. We’ve also used a little bit of floor travertine tile to cap off the shelf running through the shower.
After the shower was grouted and washed I was quite surprised how about how seamless and transparent all the different types of stone and man made tile harmonized with each other.
Next we’ve installed the cabinet, brought in granite counter top with an undermounted sink, installed back splash and none-airrated water flow faucet. 
I personal find none-airrated water flow faucets quite luxurious, for it really feels like a natural stream of water on your hands.
Last was the icing on the cake – frameless shower glass enclosure. We went with the 3/8” thick glass (instead of ½” to save a little money) and all stainless steel hardware that perfectly matched all fixtures in our new bathroom.
RESULT:
We love our new bathroom, my children and wife would make a trip downstairs just to shower, so they can experience the pleasure of a 3×5 shower with an enormous water flow from two shower heads and four body jets.
