Shower Base

Both shower pan and shower base are typically made of waterproof materials. However, since the shower base is a substructure, it is also comprised of cement mortar. Since the shower base is a substructure, it is installed as a slope. This is done so that the water can easily drain out. This is exactly how to install a shower base on a concrete floor guide.

Installing The Shower Base And Shower Pan

Now, use the tray to ensure that there are no leaks. You can do this by pouring some water on the tray and draining it to check the pipe. Once you are satisfied with how the drain works, keep the pan aside and get ready to begin the installation process.

On the concrete base, apply a layer of mortar. Make sure that you cover the entire section where the shower tray is to be installed. Now, take the pan and press it firmly into the concrete. Making use of a leveling tool, make sure that the pan is even on all sides. Now, tighten the drainage tray into place and leave the mortar undisturbed for 24 hours to dry. Once the mortar is dried and you have installed the shower walls, use silicone to seal all the cracks between the tray of the shower and the panels of the walls. After that, give it 24 hours to dry again before installing the enclosure or putting the shower into use.
