What is the newest and best custom shower pan? Its been a bit for me, but I use to set my adjustable shower drain, then use a mud base and give about 1/4" slope towards the drain, then use a rubber membrane over the curb and up 6" on the walls, cut the corners, fold and use glue to seal the joints.

Is this still the preferred method, or is there something better?

I have heard of DITRA, but never used it. Thought it was only for the walls. I will have to look into it

Ditra's an isolation membrane, like you'd use to tile the basement slab. It helps keep the floor from cracking if the slab shifts a small amount. Also a good substitute for wonderboard on a floor.

For showers, I'm a firm believer in Schluter's Kerdi product. It is stupid-simple to install, and makes for an absolutely bulletproof installation. Do a normal sloped mud pan with no membrane and the kerdi goes on right over it. It also goes on the walls and the curb.

Schluter System.
I did a custom shower for my brother about 2 years ago and his tile guys turned me onto Schluter . They claim you can spray the untiled walls {membrane only} with a fire hose and they wont leak. I couldnt get the fire dept to test that theory but i was very impressed with the system as a whole

look into tile-ready pre-made pans if your shower is a somewhat standard size

How does the mortar seal the kerdi seams? I would think that the water could seep thru the mortar on the seems......

I've never worked with kerdi, so I don't know.

Kerdi fleece membrane repels water. when you thinset the membrane together to an other membrane it becomes water proof.

Why won't the water seep between the two layers through the thinset?
