I installed approx. 2 1/2 boxes of the Dapple Gray Porcelain Tile using the thin set/mortar. After 24 hours of allowing the mortar to dry, I then used the Delorean Gray Grout.
(If you noticed, I used the same tile on the floor)
Now, you can use laminate flooring or other flooring of your choice here. I choose the tile because I live in South Florida and the humidity can cause problems with wood flooring.
I then took the flange, the steel pipe and the cap and put it together like so.
Painted all four pipes with 2 coats of Rustoleum spray paint.
Set aside and allow to dry.
These pipes will now work as my shelving brackets.
While waiting for the pipes to dry, I cut down the poplar 1 x 8 x 8 wood down to 2 -30 inch pieces to use as the shelving. I then lightly sanded and stained the two pieces using the Varathane Dark Walnut wood stain with two coats.
I figured out exactly where I wanted my shelving brackets to go. I held them up and penciled in the holes. I then drilled the holes using a tile drill bit. I then inserted wall anchors into each hole that I drilled. Once all the anchors were placed, I simply installed each shelving bracket.
I then simply laid the dried shelving ontop of the shelving brackets.
I did not screw down the wood shelving to the brackets.
(this picture makes the shelves look uneven, but I can guarantee you that I took a level to make sure it was straight. It’s just the way I took this photo) 
Here is the toilet closet finished.
