Hey everyone, if you\u2019ve ever spent time around a public pool, a backyard pool where people are constantly coming and going, or even a commercial aquatics facility, you\u2019ve probably had that moment\u2014you step onto the deck, take a deep breath, and\u2026 wait, is that strong chlorine smell? Not the fresh, slightly chemical one that keeps the water safe, but that harsh, almost sour odor that lingers in your hair, on your swim trunks, and even on the pool chairs? I\u2019ve been in the pool grating game for over a decade now, and that\u2019s one of the most common questions I get from both homeowners and facility managers alike: Are there actually pool gratings that help reduce that weird, annoying odor? Pool Grating<\/a><\/p>\n

<\/p>\n

Let me cut to the chase first: No, pool gratings don\u2019t magically eliminate chlorine from the water. But the good news is, yeah\u2014there are options out there that do a hell of a lot to cut down that lingering, unpleasant deck odor. And as someone who\u2019s tested nearly every kind of grating on the market, worked with facility managers who\u2019ve dealt with client complaints about the smell, and even helped a few backyard folks swap out their old grates to fix this exact issue, I can break this down in plain terms, no fancy jargon.<\/p>\n

First, let\u2019s get why that odor happens in the first place, because if you don\u2019t know that, you\u2019ll be chasing the wrong thing. I think a lot of people (and even some so-called \u201cexperts\u201d) mix up the \u201cchlorine smell\u201d with something called chloramines. Chloramines are the bad guys here, not the actual free chlorine we put in pools to kill bacteria and stuff. Here\u2019s the quick, dumbed-down version: Free chlorine bonds with things like sweat, urine, sunscreen, and body oils that get washed off swimmers when they step onto the deck. When that bond happens, it creates chloramines. And those chloramines are volatile\u2014they float right up into the air, hang around the deck, stick to everything, and that\u2019s the smell everyone hates.<\/p>\n

Now, how does pool grating tie into this? Because most of that gunk that creates chloramines? It doesn\u2019t just get left on the deck for people to track back into the pool. A lot of it gets washed into the grates, the gaps between old grating, and then sits there. If your grating is the kind that has tiny, hard-to-clean gaps, or it\u2019s made of material that traps moisture and that organic gunk (sunscreen residue, body oils, even hair) against itself, that gunk just sits there, breaking down, feeding more chloramine production, and releasing that smell 24\/7. I\u2019ve seen old grating in a community pool that had crusted sunscreen buildup in every crack\u2014open the drain under it, and it smelled like a dirty locker room, not a pool. That was the source of most of their odor complaints, not even the pool water itself.<\/p>\n

So what makes a pool grating odor-reducing, anyway? It\u2019s not some magic coating (well, mostly not\u2014we\u2019ll get to coatings later), it\u2019s about three key design and material choices that stop that gunk from getting stuck and breaking down. Let\u2019s break those down one by one.<\/p>\n

First, material. Most cheap pool gratings are made of basic plastic, right? Or even old-school metal that rusts. The problem with basic plastic is it\u2019s porous, even if you can\u2019t see it. Over time, water and that organic gunk seep into the tiny pores, and it\u2019s almost impossible to clean out. Metal? Rust and algae grow in the gaps, and rust reacts with the chlorine to create even more gunk that smells. The good odor-reducing gratings are usually made of either high-density polyethylene (HDPE) that\u2019s non-porous, or fiberglass-reinforced plastic (FRP) that\u2019s smooth and non-absorbent. I can tell you from testing this: I took two pieces of grating\u2014one cheap porous plastic, one HDPE non-porous\u2014and left them in a bucket of pool water mixed with sunscreen for a week. The cheap one had a slimy, smelly film on it that I could scrub, but it came back within a day. The HDPE one? Wiped clean with a paper towel, no smell, no residue. That\u2019s a huge win. Non-porous material means gunk can\u2019t seep in to sit and break down, so less chloramine production right where it would otherwise build up.<\/p>\n

Second, design. If you\u2019ve ever stepped on a grate that has tiny, narrow slots, or gaps that are too small for a pressure washer to get into, that\u2019s a problem. A lot of older grating is made for just draining water fast, not for easy cleaning. But odor-reducing grating has sloped, wide gaps\u2014usually around \u00bd inch to \u00be inch wide, not smaller. Wait, you might think smaller gaps drain better, but no\u2014small gaps get clogged with hair and dirt, and the gunk gets trapped in them. Wide, angled gaps let water and any loose gunk run right through, and they\u2019re easy to hit with a pressure washer during weekly maintenance. Another design thing: grating that doesn\u2019t have hard edges or crevices where residue can build up. Some cheaper gratings have little ridges and nooks for no reason, just to make them look different. Those nooks are just gunk magnets. I worked with a hotel last year that had their old grating replaced, and they said their housekeeping staff used to spend 2 hours a week scrubbing the grating gaps. After swapping to the wide-sloped HDPE ones? They cut that cleaning time down to 15 minutes a week, because most of the dirt and soap residue just runs through. Faster cleaning means less time for gunk to sit there and create odor.<\/p>\n

Third, the less talked-about one: anti-microbial or odor-neutralizing additives. Some of the higher-end odor-reducing gratings have small amounts of non-toxic additives mixed into the material during manufacturing\u2014think things like silver ions or zinc, which stop bacteria and algae from growing on the grating surface. Wait, but important: these aren\u2019t magic, and they don\u2019t kill all bacteria. Their job is to stop the organic gunk from decomposing on the grating. Because when bacteria breaks down sweat and sunscreen residue, that\u2019s what releases the smelly chloramines in the first place. I\u2019ve tested these additives, and I\u2019ll be honest\u2014they don\u2019t eliminate odor entirely, but they do cut it by like 60-70% for most cases. The key here is that they\u2019re mixed into the material, not sprayed on as a top coat. Top coats wear off after a year or two, especially when you\u2019re pressure washing the grating every week. The ones with additives mixed in last the whole lifespan of the grating, which is like 10-15 years, so that\u2019s a no-brainer if you\u2019re planning to invest.<\/p>\n

Now, let\u2019s get real about what these gratings can\u2019t do, because I don\u2019t want to oversell this. If your pool\u2019s pH is off, and you\u2019ve got high chloramine levels because you\u2019re not shocking the pool enough (shocking is when you add extra chlorine to burn off all the chloramines), then swapping your gratings won\u2019t fix that. The odor will still come from the pool itself, not the deck grating. But if your pool water is balanced, you\u2019re shocking regularly, and the smell is still lingering on the deck, in the pool area, even after people leave? That\u2019s 9 times out of 10 the grating is the problem. Old, porous, gunk-clogged grating is building up odor that\u2019s separate from the actual pool water.<\/p>\n

I\u2019ve got a perfect example from a client last summer: a guy named Mike who has a 15×30 backyard pool. He called me complaining that every time his friends came over, they\u2019d leave his house smelling like chlorine, even after they\u2019d showered. His pool was balanced, he was shocking it every week, so that wasn\u2019t the issue. When I went over to look, his grating was the cheap, gray plastic ones he\u2019d bought when he installed the pool 7 years prior. The gaps were tiny, and when I lifted one grate, it was full of crusted sunscreen and hair that had been sitting there for months. We swapped it out for our HDPE wide-slope odor-reducing ones, and told Mike to just spray them down with a hose every few days, no heavy scrubbing needed. A month later, he texted me saying the smell was gone\u2014his friends weren\u2019t complaining about their clothes reeking, and even his dog wasn\u2019t coming in from the deck smelling like chlorine. That\u2019s the kind of result we\u2019re talking about here.<\/p>\n

Another example: a community pool in a small town that was getting 10-15 complaints a month about the chlorine smell from local families. They were thinking of hiring a company to re-sand and seal the whole deck, which would\u2019ve cost them over $10,000. Instead, they swapped out all their old metal grating for our FRP odor-reducing ones, and cut their complaints to 1 or 2 a month, most of which were about the actual pool chemicals, not the deck. That\u2019s way cheaper, and easier than redoing the entire deck.<\/p>\n

Now, let\u2019s talk about some common myths I hear all the time. First myth: All non-porous plastic gratings are the same. Nope. I\u2019ve had clients bring me gratings from big box stores that claim to be \u201cnon-porous,\u201d and when I test them, they\u2019re just basic HDPE that\u2019s cheaply made, not the kind with the tight molecular structure that keeps gunk out. The difference is in how they\u2019re manufactured. The good ones are extruded at high heat to create a uniform, non-absorbent surface, not just molded quickly with cheap plastic. Second myth: These gratings are more expensive. Yeah, upfront they\u2019re a little more than the cheap gray plastic ones, but let\u2019s do the math: a standard 10-foot section of cheap grating is like $20. A section of odor-reducing HDPE is around $45. But that lasts 10-15 years, vs. the cheap ones which crack, get clogged, and need to be replaced every 2-3 years. Over 10 years, the cheap ones cost you $200, the odor-reducing ones cost $135. Plus, you save on maintenance time\u2014less scrubbing, less pressure washing, less repairing broken grating. It\u2019s a no-brainer for most people.<\/p>\n

Third myth: These gratings eliminate chlorine smell entirely. No, like I said earlier, if your pool has high chloramine levels from bad water balance, you\u2019ll still smell that. But it takes the deck out of the equation. The deck is where the smell sticks to everything, so if the deck grating isn\u2019t building up extra gunk and releasing extra chloramines, the overall odor is way milder, and doesn\u2019t linger.<\/p>\n

So who should actually invest in these odor-reducing gratings? Let\u2019s make that clear. If you\u2019re a homeowner with a pool that gets used a lot\u2014summer parties, kids running in and out, lots of sunscreen and body oil getting tracked onto the deck\u2014swap your old grating. If you own a commercial pool, a hotel pool, a gym pool, a community pool where you get constant odor complaints from customers or residents, this is a simple, low-cost fix that will make way more people happy. Even if you just got tired of your swimwear smelling like chlorine three days after you wore it, swapping your grating is way easier than changing your pool\u2019s chlorine levels.<\/p>\n

Now, a quick note on installation, because a lot of people think this is a big job. No, most grating is designed to fit into existing pool deck channels. You just lift out the old ones, drop the new ones in, and they click into place. No special tools, no concrete work needed. I\u2019ve had homeowners do it in a Saturday, no contractor required. For larger facilities, we can send our installation team to do it in a day or two, so minimal downtime for the pool.<\/p>\n

Wait, one thing I almost forgot: What about if you have parts of the deck that don\u2019t have grating? Like the flat areas around the pool. Can you get odor-reducing products for those too? Sometimes, but that\u2019s a different deal. The grating is the main culprit because that\u2019s where all the gunk gets trapped and sits. The flat deck is fine as long as you\u2019re sweeping and hosing it regularly, but the grating gaps are the real problem spot. So focusing on swapping your grating is the most effective fix.<\/p>\n

<\/p>\n

Let me wrap this up, because I know a lot of you are probably wondering where to go from here. If you\u2019re tired of the lingering chlorine smell at your pool, don\u2019t just put up with it.
