Today I installed the rain shower in the downstairs bathroom, right next to the tub.
The picture below shows the pex lines coming in, the valve and the top connection where the shower is connected.

Like most good ideas, it was a good idea in theory; making the tiled floor run down t0 a drain point,
so that a rain shower could be mounted to the wall next to the tub.
So I used normal hardy backer board for the largest part, and 1/4″ thinner hardy backer board for the drain area,
and used an aluminium ruler to make the slope from the thick hardy backer board to the thinner board using thinset
thus creating a slope down. So far, so good. In theory. In practise, the entire floor slopes down the wrong direction,
and the only level part is the part that was supposed to be sloped down.

So the problem I now have to solve is that the water runs down from tile row three,
all the way to the other side of the bathroom.
What I’m thinking to try first is put a barrier line of transparent silicon kit to form an invisible shower pan.
It will only need to be like a quarter inch tall, and if I put it in the grout, you would not see it.
If that doesn’t work I will have to create a shower pan using a small strip of tile.
But that would not look as nice and might be something you bump into with your toes.
So I will try the silicon kit tomorrow, after the floor has dried.
