A shower strainer looks like a small detail, but the wrong one can leave you with a slow-draining shower, loose hardware, or a cover that simply won’t fit. The good news is that choosing one gets much easier once you know what to measure, how your drain is built, and what kind of hair and debris it needs to catch.

What a Shower Strainer Does
A shower strainer is the visible part of the drain that lets water pass while catching hair and larger debris. It may be called a shower drain cover, grate, or drain screen. In some setups, the strainer is a removable insert; in others, it’s built into the drain assembly.
That distinction matters. A strainer sits at the top of the drain, but the drain assembly beneath it carries water into the plumbing and connects to the shower base. If you’re replacing only a worn or unattractive cover, you may be able to leave the assembly in place. If the assembly is damaged, leaking, or the wrong style for your shower, swapping the cover alone won’t solve the problem.
Start by Checking What You’re Replacing
Is it a cover, a hair catcher, or a complete drain?
Before shopping, look at your current drain and see whether the strainer lifts out, screws down, or is attached to a larger fitting. A simple snap-in hair catcher is often easy to remove for cleaning. A screw-fastened cover may need a matching screw pattern or a compatible drain body. A complete drain replacement is a larger plumbing job, especially if it requires access beneath the shower.
If you’re unsure, remove the existing strainer only if it comes out easily, then take a clear photo of the drain and any markings. Don’t pry at a fixed cover or force a screw that won’t turn; you could damage the drain or shower surface. A plumber or the drain manufacturer can often identify the style from a photo and a few measurements.
Measure for a Proper Fit
Fit is the first practical test. A strainer that’s too small can shift or leave gaps where hair slips through. One that’s too large may not sit flat, which can create a tripping edge or stop water from draining properly.
Measure the opening and the outside width or diameter of the existing cover. For a round strainer, measure straight across the widest point. For a square or rectangular one, measure both the length and width. If it’s held by screws, note the distance between the screw centers as well.
Also check how the strainer attaches. Common styles include screw-in covers, snap-in covers, lift-out baskets, and covers that fit a specific drain brand or model. Two strainers can look nearly identical from above but have different clips, threads, or screw spacing underneath. Compare the attachment method, not just the shape.
Don’t confuse the cover size with the pipe size
The visible opening and the plumbing connection below it are not necessarily the same measurement. A drain cover’s width doesn’t tell you the size or type of pipe connection underneath. Drain designs and local plumbing requirements vary, so don’t order a full drain assembly based only on the diameter of the visible grate.
If you’re replacing the entire drain, find the brand and model if possible, check the installation instructions, or ask a plumber to confirm what will fit your shower base and plumbing. That extra check can save you from buying a part that looks right but cannot connect properly.
Choose a Strainer That Matches Your Shower
| Shower or drain setup | What to look for | Why it matters |
|---|---|---|
| Standard shower with a round drain | A round cover that matches the opening and attachment style | The right fit helps it sit flat and stay secure. |
| Tile shower with a square drain | A square grate made for the existing drain body | Grates may need to align with the tile layout and drain frame. |
| Linear or trench drain | A strainer or grate made for the specific channel system | Length, width, and support design are often system-specific. |
| Shower that clogs with hair | A removable hair-catching basket or screen that still allows good flow | It can catch hair before it reaches the plumbing, but needs regular cleaning. |
Tile showers deserve extra care because the drain cover may be part of a larger waterproofing and drainage system. Replacing the visible grate is different from disturbing the drain body or waterproofing layer. If the drain assembly itself needs work, get qualified help rather than guessing at a replacement.
Pick a Material for Your Needs
Stainless steel
Stainless steel is a common choice because it’s sturdy, easy to wipe clean, and available in several finishes. It usually holds up well in a wet bathroom, though the quality and finish vary. If you use strong cleaners, check the care instructions; harsh products can dull or damage some finishes over time.
Brass and other metal finishes
Brass and coated metal strainers can work well when their size and attachment match your drain. They’re often chosen to coordinate with faucets and shower fittings. Keep in mind that a finish is not the same as the underlying material: a decorative coating can wear, especially if it’s scrubbed with abrasive pads.
Plastic
Plastic strainers are lightweight and can be a practical option for a removable hair catcher or a compatible drain cover. They may cost less, but their durability depends on the design and how they’re used. If you remove and clean the strainer often, look for a solid construction and a secure fit rather than choosing on price alone.
Whatever the material, look for smooth edges and a surface that’s easy to clean. A strainer has to be handled regularly, so a design that traps grime in tiny corners can become frustrating even if it looks good when new.
Balance Hair Catching with Water Flow
A very fine screen can catch more small debris, but it can also clog faster. When hair and soap residue cover the openings, water has less room to pass through. That’s why a strainer that seems excellent at catching everything can leave you standing in a shallow pool if you don’t clean it often.
Think about the people who use the shower. Long hair, shedding pets washed in the shower, or several daily users may make a removable hair basket especially useful. If hair isn’t a major issue, a simpler grate with larger openings may be easier to maintain. In either case, the strainer should not block the drain’s intended flow.
Don’t remove or modify the strainer to make a slow drain seem faster. If water still drains poorly after you’ve cleaned the cover and removed visible buildup, the blockage may be farther down the pipe. A strainer change can’t clear a clogged drain line.
Consider Cleaning and Everyday Use
The best shower strainer is one you’ll actually keep clean. A removable basket is easy to empty, but you’ll need to lift it out regularly. A flat grate may look neat and be simple to wipe, though hair can collect underneath it. Choose a style that feels manageable for your household, not just one that looks good in a product photo.
- For frequent hair buildup: Choose a removable catcher that lifts out without tools.
- For a low-profile look: Choose a flush-fitting grate that matches the drain system.
- For easier cleaning: Avoid designs with deep, narrow grooves that are hard to reach.
- For shared bathrooms: Pick a durable model that is simple for everyone to remove and rinse.
Clean the strainer before it becomes heavily clogged. In a home with long-haired residents, that may mean checking it every few showers; in another household, a weekly check may be enough. Rinse away hair and soap residue, then wash the part with a bathroom-safe cleaner that won’t damage its finish.
Check Installation and Safety Details
For a cover-only replacement, installation may be as simple as placing it in the drain or securing it with the correct screw. Follow the maker’s instructions and make sure the strainer sits level, feels stable, and doesn’t rock when pressed. A loose or raised cover can catch a toe or shift underfoot.
Use the correct fastener if the design calls for one. A screw that is too long or the wrong type may not secure the cover properly and could interfere with parts beneath it. Avoid relying on glue or improvised fixes unless the manufacturer specifically recommends them.
If you see water around the drain, staining on the ceiling below, a persistent sewer-like smell, or movement in the drain body, treat it as more than a strainer problem. Those signs can point to a plumbing or waterproofing issue. Stop using the shower if you suspect a leak and arrange an inspection.
A Simple Buying Checklist
Before you buy a shower strainer, confirm these details:
- Measure the existing cover and drain opening.
- Record the shape and any screw spacing.
- Identify whether you need a cover, a hair catcher, or a full drain assembly.
- Match the attachment style and, where relevant, the drain brand or model.
- Choose a material and finish that suit your cleaning habits.
- Make sure the design catches the debris you care about without clogging too quickly.
- Check the return policy in case the part doesn’t fit.
When in doubt, bring the old removable strainer to a plumbing supply store or contact the manufacturer with photos and measurements. That’s usually more reliable than choosing by appearance alone.

Frequently Asked Questions
How do I know what size shower strainer I need?
Measure the existing cover’s width or diameter, the drain opening, and any screw spacing. Also match the attachment style. If you’re replacing the full drain assembly, confirm the plumbing connection and compatibility separately; the cover measurement alone isn’t enough.
Are shower strainers universal?
No. Some simple covers fit common openings, but screw patterns, clips, shapes, and drain systems vary. Check the measurements and attachment method before ordering.
Should I choose a fine mesh strainer?
Fine mesh can catch smaller debris, but it tends to collect hair and soap residue quickly. It’s a reasonable choice if you’re willing to clean it often. For less maintenance, consider a removable hair basket or a design with openings that balance catching hair with water flow.
Can I replace a shower strainer myself?
You can often replace a cover or removable catcher if it lifts out or uses an accessible screw. Replacing the drain body can involve plumbing connections and the shower’s waterproofing, so it’s best left to a qualified professional when you’re unsure.
Conclusion
To choose a shower strainer, start with the fit: measure the cover, check how it attaches, and confirm whether you’re replacing a simple grate or a complete drain part. Then choose a material and hair-catching style that suit your shower and cleaning routine.
A well-fitting strainer should sit securely, let water flow freely, and be easy to clean. Taking a few measurements before you buy is a small step that can save you a frustrating return—or a much bigger plumbing problem.
