We are installing a new shower in the basement using a ceramic tile base on a cement floor. The drain has already been relocated to the proper position and the next step is to pour another thin layer of concrete over the floor in order to get the proper slope to the drain.
The shower base size will be 34"x58" inside. The concrete base will be 38x62 to accomodate a 4" glass block wall half way down one side and the end of the shower.
The questions are, what should be the thickness of the contoured concrete. We were planning 2 inches at the edges with a slope of 1/4 to 1/2 inch from the edge to the drain.
What is the proper type or mix of conrete. We were planning portland cement and sand in a ratio of 5 to 1.
Is is necessary to install a water proof membrane between the existing floor and the new concrete since the base will be poured on a basement floor and butting on cement board?
What would you recommend for a sill height above the shower base? Please note the shower base is quite large and the opening will be at the far side of the base.
How long should I wait for the cement to cure until I install the mosaic tile on the base?
Thanks for any help you can offer.
