Depends on the shower base you plan on using. If you are hiring the tile out, ask your tile guy what he’s going to do for the base. If you are doing it, plan out what you are doing for your base and make sure floor is constructed to accommodate. There are so many options you really need to pick one and go with that. Sometimes with linear drain you don’t really have to bring floor down to accommodate, but again all has to be planned ahead of time.
You would need to drop your joists down far enough to get at least a 2" thick pitched slab on top of the sheathing.
I was leaning towards a mud base or Schluter System base ?
If a mud base you definitely need to drop the floor. Depending upon length of your pitch you may need to go deeper than 2”.
With Schluter preformed shower board you may not technically need to drop down floor at all. The thinnest sloped board goes all the way down to 3/16” thick on low pitch side. You will probably need to incorporate a linear drain to do this and have it installed at shower door (or door) if building entire bath floor as shower pan. I’ve attached a pic and you can also refer to Fine Homebuilding issue 255, they describe the process there. If no linear drain is being used and you want to slope away from door you will need to drop the floor some. To determine that dimension check your lengths and determine the thickness of Schulter board required to achieve your slope.
Give Hydroban a good look. I‘ve used the Schluter system a couple times, but once I tried Hydroban never went back. I find it easier/quicker to install. It’s approved for outdoor swimming pools, so holds up well. Have had no problems at all. All my tile guys use it as well, they turned me on to the stuff initially.
Flood test before you install tile. I’ve actually never had a leak, but if you do it will be a major pain to fix after tile is installed.
WOW !
Excellent explanation, I understand
Thanks to everyone
