How to Pour a Tile Shower Pan

Lay roofing paper and steel mesh over the floor of the shower and staple it to the floor with a heavy duty stapler. Cut away the material over the drain hole with metal cutters and a razor. Mount the bottom of the shower drain to the floor with the provided mounting bolts and a wrench.

Create a batch of sand mix concrete, available at a regular home improvement store, and spread it over the floor of the shower with a trowel. Flatten the sand mix into a bed that slopes towards the drain hole. Check the slope with a carpenter level and adjust as necessary to make it even all the way around the drain. Allow 24 hours of drying time.

Spread the shower liner over the concrete bed. Fold back the liner at the corners and staple the liner to the wall. Cut an opening over the drain, apply silicone caulking to the top section of the shower drain, and bolt this section to the bottom of the drain with the bolts provided by the manufacturer and a wrench.

Make another batch of sand mix and spread this over the liner to create a second layer for the shower pan. Tamp this layer down with a hand trowel, following the taper of the concrete floor beneath it. Let it dry for another 24 hours.
