I saw this question, but i can’t find the answer to it. the area where i want build the shower does not match the measurements in shower base catalogues. I chose to build the shower base myself using mortar on the cement floor. When the house was being built we order to have rough ins for a three pieces bathroom. I need help and advices on how to proceed step by step on building this mortar shower base. what type of cement I need to use, the thickness, and all others materials.
Please and thank you.
