Everything You Need to Know About Shower Drain Covers

Shower Drain Covers Explained: Sizes, Types, and Tips

When it comes to bathroom fixtures, the shower drain cover might seem like a small detail—but it plays a surprisingly important role. It maintains cleanliness, prevents clogs, and enhances the overall look of your shower. If you’ve ever wondered about the types, sizes, functions, and maintenance of shower drain covers, this guide will walk you through all the essentials.

What Is the Drain Cover in the Shower Called?

The piece you see in your shower floor that covers the drain opening is called a shower drain cover or shower strainer.

• A drain cover typically refers to the decorative, removable piece that allows water to flow through. It also prevents larger debris from entering the pipe.
•  A shower strainer is often used interchangeably, especially when the cover has holes, slots, or grates for drainage.

Some models are round, while modern bathrooms may use square or linear drain covers for aesthetic and functional purposes.

What Is the Standard Size of a Shower Drain Cover?

Most shower drain covers come in standard sizes, though variations exist depending on the manufacturer:

• Round covers: The most common size is 4 inches in diameter, but some range between 3 to 6 inches.
• Square covers: Typically 4 x 4 inches or 5 x 5 inches.
•  Linear covers (long, rectangular styles): These vary widely, usually 24 inches, 36 inches, or even 60 inches long depending on the shower’s design.

If you’re replacing a drain cover, it’s best to measure your existing one or check your drain brand’s specifications before buying a new one.

 Does Covering the Drain Stop Drain Flies?

Drain flies (also called sewer flies or moth flies) are tiny insects that thrive in damp environments and breed inside drains with organic buildup.

• Simply **covering the drain with a cap or plug will not eliminate them**. Although it may prevent adult flies from escaping temporarily, it won’t address the larvae breeding inside the drain.
• To get rid of drain flies, you’ll need to clean the drain thoroughly. You must remove slime, hair, and organic material where they breed. Moreover, pouring a drain-safe cleaner or a mixture of baking soda and vinegar can help. Follow that with hot water for effectiveness.

So, while covering the drain may reduce the nuisance, cleaning is the real solution.

How to Take Off a Square Shower Drain Cover

Removing a square drain cover is usually straightforward. However, the method depends on whether it’s held by screws or pressure-fitted:

1. Check for Screws

• Look at the corners of the cover.
• If screws are present, use a screwdriver (usually Phillips-head) to remove them.
• Then, lift the cover once the screws are removed.

2. Pressure-Fitted (No Screws)

• Use drain removal tool and insert in gaps of the drain.
• Pry upward gently to loosen the cover.
• Use gloves to lift it off to avoid sharp edges.

Drain Removal Tool

3. Stubborn Covers

• Apply a little WD-40 or soapy water around the edges.
• Wiggle the tool underneath until the cover pops loose.

Pro tip: Place a cloth in the drain opening while working to avoid dropping screws or tools inside.

What Are the Disadvantages of a Linear Shower Drain?

Linear drains are modern and stylish, often running along one edge of the shower floor. While they have aesthetic appeal and great water flow capacity, they also come with a few drawbacks:

1. Higher Cost

* Linear drains and their installation tend to be more expensive than standard round or square drains.

2. Installation Complexity

* Requires precise slope adjustments in the shower floor to ensure proper drainage.
* May need professional installation, which increases cost.

3. Maintenance

* The long, narrow design can trap hair and debris more easily, requiring frequent cleaning.

4. Limited Retrofit Options

* Installing a linear drain in an existing shower may not be feasible without major remodeling.

5. Potential for Improper Flow

* If not installed correctly, water may pool or flow too slowly toward the drain.

 Final Thoughts

Whether you’re replacing a simple round cover, dealing with drain flies, or considering a sleek linear drain for a remodel, understanding the details about shower drain covers can save you time, money, and hassle.

A well-maintained shower drain cover not only keeps your bathroom functional but also helps maintain hygiene and enhances your shower’s overall design.
