Underlying the tile question for tile experts Bill and Mongo
In anticipation of renovating our bathrooms in a NYC prewar apartment and having read many posts about tile problems/water leak issues I wondered if Bill V and Mongo could clarify my interpretation of the readings I've done. I don't want to be surprised by the contractor!
Here is my understanding. Am I correct?
1) Bathroom floors: subfloor--then mortar bed--then Cement Backing Unit (CBU)--then lay tiles with thinset and then grout tiles(laticrete)?
2) Shower walls in bathroom with tub: CBU--then membrane (?)--then lay tiles with thinset and then grout tiles (laticrete)?
3) Shower stall floor in bathroom without tub: subfloor--mortar bed--kerdi drain--shower membrane --lay tiles with thinset and then grout tiles (laticrete)?
Thank you in advance for correcting any mistakes and guiding me.
