To install a Sterling shower base, follow these steps:
1. Measure the space and ensure it meets the requirements for the chosen shower base size.
2. Prepare the subfloor by removing any debris and leveling it.
3. Apply a waterproofing membrane to the subfloor to protect against leaks.
4. Place the shower base in the desired position and check for levelness.
5. Connect the drain assembly according to the manufacturer’s instructions.
6. Secure the shower base to the subfloor using screws or adhesive, as recommended.
7. Install the shower walls and secure them to the shower base.
8. Apply a silicone sealant around the edges of the shower base to prevent water leakage.
9. Allow the sealant to dry, then test the shower for any leaks before use.
When it comes to installing a Sterling shower base, having advanced carpentry and plumbing skills is necessary. This one-piece shower floor unit is designed to be installed flush against the wall framing and subfloor in the shower area. Its purpose is to efficiently drain water and direct it towards a single drain hole.
In order for the shower base to drain properly, it must be placed on a level surface. Therefore, preparing and leveling the subfloor are crucial steps that need to be taken before the actual installation of the shower base. If the floor is stable and level, the nails holding the base to the studs are sufficient for support. However, if the floor is not level, it is recommended to set the base in a mortar bed, similar to a bathtub installation.
A Step-by-Step Guide to Installing a Sterling Shower Base
Step 1: Removing the Existing Shower
Begin by removing the existing shower walls. Cut the drywall into sections using a drywall saw and pry off the sections. Strip the shower area down to the framing, making sure to exercise caution when cutting through the drywall to avoid damaging any plumbing pipes behind the wall. Clean the entire area and remove any waste with a push broom.
Step 2: Installing the Shower Drain in the Base
Insert the top half of the shower base drain assembly into the drain hole, ensuring that the threaded end points through the bottom of the base. Slide the gaskets around the bottom of the drain and thread the lower half of the drain onto the unit. Use tongue-and-groove pliers to tighten the two halves and secure the drain.
Step 3: Leveling the Shower Base
If the installation area is not a plywood floor, cut a hole in the subfloor for the drain and dry fit the Sterling shower base. If necessary, install the supplied mounting pad in the showering area first. Press the shower base against the framing walls and check the level on every side. Use plastic shims to level the base wherever needed, as wooden shims may rot if they come into contact with water.
Step 4: Creating a Mortar Bed (Optional)
If the shower base is not level and cannot be leveled with shims, it is recommended to install a mortar bed. Mix mortar in a 5-gallon bucket and install a dam inside the drain hole. Use a trowel to spread the mortar over the installation area.
Step 5: Nailing the Base to the Wall Studs
Remove the drain dam and place the shower base in the installation area. Press the base into position, ensuring that the sides are flush with the framing walls. Use a carpenter’s level to check the base for levelness. Once level, nail roofer’s nails onto the studs directly above the shower base lip to secure it. Install the shower base fasteners onto the stud framing to further secure the base in place.
Step 6: Installing Cement Board on the Walls
Using drywall screws and a power screwdriver, install cement board on the framing walls, overlapping the shower base lip. Seal the seams between the shower base and cement board with silicone sealant.
