A shower drain is responsible for directing water efficiently into the plumbing system while preventing leaks, odors, and moisture damage. A properly installed drain ensures stable performance, hygienic conditions, and long-term protection for the shower structure. For manufacturers such as Moon Shower—known for durable, precisely designed shower components—the drain installation is a critical foundation of a well-functioning shower system.
Shower drain assembly
Plumber’s putty or waterproof sealant
Screwdriver
Adjustable wrench
Drain flange and gasket
PVC or ABS glue (for certain drain types)
Utility knife
Shower pan or tile-ready base
Gather these items before starting to ensure a smooth, efficient installation.
If installing a pre-fabricated shower pan:
The drain hole matches the drain assembly
The pan is level
The subfloor is structurally sound
A stable base ensures proper drainage and prevents cracking.
Roll a small amount of plumber’s putty between your hands and place it under the drain flange.
Creates a watertight seal
Prevents leaks between the flange and shower pan
Press the flange firmly into the drain opening.
If you can access the underside of the shower pan, insert the drain body from underneath.
Align the threads with the drain flange
Tighten the drain body onto the flange
Ensure the gasket is seated properly
A tight connection prevents leaks between the pan and plumbing system.
Use a wrench or drain tool to tighten the drain from above.
Do not overtighten. Excess pressure can damage the pan or break the seal.
Once tightened, remove excess putty squeezed out around the flange.
Depending on your plumbing layout and drain type, connect the drain pipe using:
PVC glue
ABS glue
Compression fittings
Proper alignment
Secure connection
No gaps or misalignment
This ensures smooth water flow and prevents leaks below the shower.
Before finalizing the installation:
Plug the drain
Fill the shower pan with a few inches of water
Let it sit for 20–30 minutes
Inspect the underside of the drain pipe
If there is any moisture, tighten the assembly or reapply sealant.
Attach the drain cover using screws or snap-in mechanisms.
Prevents debris from entering the drain
Helps maintain long-term drainage performance
Moon Shower’s drain covers are engineered for durability and easy cleaning, ensuring consistent hygiene and water flow.
If you are installing a drain in a tile-ready shower system:
Install the lower drain flange
Apply waterproof membrane over the pan and clamp it
Insert the upper drain section
Adjust the drain height to match tile thickness
Tile around the drain and grout
Apply waterproof sealant
A properly set drain height ensures smooth water flow and avoids pooling.
Can lead to leaks around the flange.
Causes slow drainage and potential pipe stress.
Results in standing water and improper drain performance.
Small leaks can cause major subfloor damage over time.
May crack the shower base or deform seals.
Prevents hair and debris buildup.
Helps reduce soap residue and oils.
Early signs of blockage allow for quick correction.
Avoid harsh chemicals that may damage seals or piping.
Moon Shower focuses on creating shower components that support long-term performance and easy maintenance.
Corrosion-resistant drain materials
Smooth interior surfaces that reduce clogging
Secure, user-friendly assembly designs
Durable coverings for hygiene and protection
Compatibility with modern shower pans and tile systems
These engineering qualities ensure the drain system works seamlessly with the rest of the shower fixtures.
