This viscous, waterproof paste is primarily used to seal joints where two surfaces meet (e.g., where the tub meets the wall) or to fill cracks (which commonly crop up in the shower floor) to keep out air, moisture, and dirt. To defend your shower or tub against these threats, the garden-variety latex caulk commonly used on drywall, window frames, and wooden doors simply won’t cut it. The best caulk for the shower or tub has special properties that keep it pristine and structurally intact in the unique environment of the bathroom. With so many kinds of bathroom caulk available, it can be tough to figure out which is the best for your situation. We talked to an expert who knows exactly where most homeowners can go wrong with caulking their shower, and took their advice on board when picking our products. Then, we performed hands-on testing with the following caulks in order to suggest only top-notch products. With that in mind, we selected the [Gorilla Waterproof Silicone Caulk & Seal]() as our best overall caulk for showers for its waterproof, shrink- and crack-proof, and rain-ready formula with a 30-minute drying time. Read on for aspects to consider when buying caulk for your bathroom project and see why we find the following products to be some of the best caulk for showers. 1. **BEST OVERALL:** [Gorilla Waterproof Silicone Caulk & Seal ]() 2. **BEST BANG FOR THE BUCK:** [DAP Kwik Seal Plus White Premium Caulk]() 3. **BEST FOR SMALL REPAIRS:** [GE Advanced Silicone 2 Kitchen & Bath Sealant ]() 4. **BEST QUICK-DRYING:** [GE Supreme Silicone Kitchen & Bath Sealant]() 5. **BEST PAINTABLE:** [Red Devil Kitchen & Bath Siliconized Acrylic Caulk]() 6. **BEST FOR SEAMS:** [DAP Kwik Seal Ultra White Advanced Siliconized Caulk]() 7. **ALSO CONSIDER:** [Loctite Polyseamseal Acrylic Caulk with Silicone]() ![The Best Shower Caulk Options]() *Photo: Tom Scalisi* ## Shower Caulk Comparison | | **Type** | **Paintable** | **Dry time** | | --- | --- | --- | --- | | [Gorilla Waterproof Silicone Caulk & Seal]() | Silicone | No | 30 minutes | | [DAP Kwik Seal Plus White Premium Caulk]() | Siliconized latex | Yes | 2 hours (paintable), 24 hours (shower-ready) | | [GE Advanced Silicone 2 Kitchen & Bath Sealant]() | Silicone | No | 30 minutes to 24 hours | | [GE Supreme Silicone Kitchen & Bath Sealant]() | Silicone | No | 30 minutes to 24 hours | | [Red Devil Kitchen & Bath Siliconized Acrylic Caulk]() | Siliconized | Yes | 72 hours | | [DAP Kwik Seal Ultra White Advanced Siliconized Caulk]() | Siliconized | No | 4 hours to 24 hours | | [Loctite Polyseamseal Acrylic Caulk with Silicone]() | Siliconized acrylic | Yes | 30 minutes to 24 hours | ## Our Top Picks There is a lot to know about choosing the best caulk for a shower or a tub, and shopping for just the right product can feel overwhelming. To help, we performed hands-on testing with all of the following products. After using them, we chose certain awards that we felt best fit their strengths. Use our observations and the above considerations when looking for caulk for your shower space. Gorilla’s adhesives tend to be a step above the competition, and the same is true for this clear sealant caulk. This 100 percent silicone caulk adheres to most bathroom surfaces easily to create a mold- and mildew-resistant barrier. It remains flexible throughout its life, and it won’t shrink or crack like some siliconized caulks might. It dries in just 30 minutes, making it useful for quick repairs or even full bathroom installations. During testing, we found Gorilla caulk & seal to be a top-quality product. It applied easily and created a strong bond for the shower surround. Once dry, we found it was barely noticeable, and the fact that it remains flexible and won’t yellow leads us to believe it’ll stay unnoticeable. While it’s not paintable, this product will work on any seam that needs to be waterproof but doesn’t need a coat of paint. We also liked that it flowed well, was easy to tool, and was not too sticky to tool with a wet finger. Be advised that this product is not suitable for use in aquariums or on brick, masonry, metals, or cement. **Get the Gorilla caulk at** [**Amazon**]() **or** [**Walmart**]()**.** Anyone shopping for an affordable caulk that will get the job done for less than half the cost of some of its competitors may want to check out DAP Kwik Seal Plus. This siliconized latex caulk creates a 100 percent waterproof barrier and features Microban for antimicrobial protection that fights stain-causing mold, fungus, and mildew. Its paintable formula requires 2 hours of drying time before applying paint, and then 24 hours before showering. According to the manufacturer, this option has outstanding adhesion to ceramic and plastic tile, porcelain, metal, cultured marble, drywall, metal, painted surfaces, glass, fiberglass, and wood. Kwik Seal Plus is affordable, but it’s not low on quality. We liked how easy this product was to apply, but it was even easier to clean up—a wet rag is all it took to clean some excess from the tub surface. While the 2-hour dry time seems to betray the product’s “Kwik” moniker, our applied caulk appeared to dry slightly faster (about an hour in our conditions). This allowed us to test it with paint on a spare surface. It passed this test well, taking paint without issue. **Get the DAP Kwik Seal Plus caulk at [Amazon]() or** [**The Home Depot**]()**.** Cracks, leaks, and other shower woes can happen in some challenging spaces, and getting [a caulking gun]() into position can be tricky. However, with a 2.8-ounce or 10.1-ounce tube of Advanced Silicone from GE, DIYers can make repairs in both tight and large spots. This shrink- and crack-proof caulk features a 100 percent silicone formula that remains flexible and waterproof for up to 10 years. It is low-odor and adheres to metals, plastic, wood, glass, tile, and fiberglass, and it dries in 30 minutes. Here’s what we noticed about the GE Advanced Silicone: It might be a lot of work to caulk a whole shower with these tubes, for but small repairs, they’re incredibly convenient. They’re easy to use yet still apply consistent beads of silicone. While we prefer our shower caulk in white, this clear silicone was barely visible and created a strong, flexible seal. **Get the GE Advanced Silicone caulk at** [**Amazon**]()**,** [**Lowe’s**]()**,** [**The Home Depot**]()**,** [**Ace Hardware**]()**, or** [**Walmart**]()**.** A quick-drying caulk doesn’t do much good if a DIYer has to redo it when it shrinks and cracks. That’s not the case with GE’s Supreme Silicone. This special, low-odor formula creates a waterproof and mold-resistant barrier that doesn’t shrink, crack, or yellow over time. And, better yet, it does it while drying in just 30 minutes, but users should wait up to 24 hours for the best results. We used the Supreme Silicone along the longest seam in our test tub and shower, and we were very happy with the result. Not only did it flow well, but it was also reasonably easy to clean up after (for a silicone caulk). Our bead dried in 30 minutes, and the bright white caulk gave the seam a nice finished look. We did have a relatively large gap in the bottom of the surround that we needed to apply a bit extra to, and the 30-minute dry time was a big boost. The only downside that we found is this product isn’t paintable. **Get the GE Sealants & Adhesives caulk at** [**Amazon**]()**,** [**Lowe’s**]()**,** [**The Home Depot**]()**, or** [**Ace Hardware**]()**.** It can be tough to find a caulk for a shower or tub that creates a good seal with plenty of adhesion and also takes paint well, but Red Devil’s Duraguard Kitchen & Bath Caulk does the trick. This low-VOC product features a special formula that adheres to porcelain, ceramic, marble, glass, plastic, vinyl, fiberglass, and more, though it takes up to 72 hours to dry. It also has a HomeShield Antimicrobial protection that keeps the formula mold- and mildew-free. Here’s the thing about Red Devil Duraguard Kitchen & Bath Caulk: the drying time is very long, and it’s important to wait to prevent brush strokes or pulling some of the caulk from the bead. However, we found that once we let it dry, it took paint well while remaining fairly flexible. We liked that it can adhere to a variety of surfaces to create a waterproof barrier, and it comes in white, clear, and tan. **Get the Red Devil caulk at** [**Amazon**]()**.** Whether it’s a new shower going in or a shower getting a refresh, DAP Kwik Seal Ultra can help those seams blend in for a fresh, clean look. This low-odor and low-VOC caulk features a siliconized formula that dries to a glossy white finish and repels stains, dirt, and water, providing a waterproof surround when used to caulk seams. The resulting bead won’t crack or shrink and remains flexible after drying (which takes 4 hours) while offering stain-proof protection. For best results, users should wait over 24 hours before exposing the caulk to water. Of all the caulks we used on the shower seams, this one dried to the nicest finish. It has a slightly shinier finish than the others, which blends in well with the shower surround. It flowed well and was easy to tool and clean up. The result was a clean, sharp seam that looks good, despite the 4-hour drying time necessary before we could check it out. The one thing that threw us for a loop is that this product isn’t paintable, even though it’s not 100 percent silicone. **Get the Dap Kwik Seal caulk at** [**Lowe’s**]()**,** [**The Home Depot**]()**, or** [**Ace Hardware**]()**.** For yet another shower caulk option, check out Loctite Polyseamseal Acrylic Caulk with Silicone. This product features a special siliconized acrylic formula to help it remain flexible and waterproof, and it can even work as an adhesive in some cases (like securing loose backsplash tiles). The formula is paintable once dry, which takes just 30 seconds to accomplish when using latex paints. However, users who rely on oil-based paints should wait 24 hours before applying. We’ll be honest: We did not apply the bronze-colored Loctite Polyseamseal Acrylic Caulk we received to the new white shower surround. Instead, we tried it on the scrap tub we removed, and we liked what we found. First, it adhered well to the fiberglass surround and dried in just 30 minutes, allowing us to test it out with some paint (which it didn’t handle especially well, mostly due to the caulk’s dark color). Luckily, this product is also available in white or clear. It also cleaned up easily, which we discovered when we dripped some on the floor near the scrap tub. **Get the Loctite caulk at** [**Amazon**]() **or** [**Walmart**]()**.** ## [Jump to Our Top Picks](<#recap>) ## How We Tested the Best Caulk for Showers | **Testing Stats** | | | --- | --- | | Products tested | 8 | | Hours spent testing | 24 to 72 hours per caulk | | Tests performed | 3 per caulk | | Price range | $10 to $15 | Before rounding up our products for testing, we interviewed Roy Barnes, co-owner of [Service Force Plumbing]() in Rockville Maryland, who has several decades of plumbing experience and wanted to share his two cents on shower caulk. “We regularly get service calls for ‘leaking pipes’ that turn out to simply be poor or worn-out waterproofing. Customers will see spots on their ceiling below their bathroom, and they'll pay a plumber for a service call, when in fact their shower or tub just needs better caulking to prevent water from escaping.” He adds that “keeping your shower or tub properly caulked is a key step to avoid water damage, mold, and confusion over where dripping water might be coming from.” With this advice in mind, we took steps to gather the top products available and put them to the test. Originally, we were going to set up a bunch of fiberglass boxes and caulk all the seams with the different types of caulk, but we scrapped that idea in favor of replacing a shower. So we ordered a shower and set about installing it, using the caulks to waterproof the enclosure. Each of the caulks (except for the bronze one) was used to caulk a seam inside the shower, and we checked each seam at the designated time to ensure it was dry. Next, for caulks that were paintable, we applied them to the scrap shower we removed and let them dry. After they dried, we painted them and tested their flexibility. With those tests behind us, we had a good idea of which products were a hit or not. We used those tests and personal experience to develop our list of the best caulk for a shower. ## What to Consider When Choosing Caulk for Showers and Tubs Finding the best caulk for a shower or tub requires thorough knowledge of the types of caulk on the market, the formula of the caulk, and if it offers the best long-term solution to [mold or mildew](). To determine the best option for a given bathroom space, consider some of the factors below. ### Types of Caulk for Showers and Tubs Caulk made of pure silicone or siliconized latex/acrylic (i.e., latex or acrylic caulk with added silicone) adheres well to common shower and tub materials, including porcelain, ceramic, stone, fiberglass, and glass. - Choose **pure silicone** for a more durable caulk job that won’t come in contact with paint afterward. It’s more waterproof and flexible, so it better resists rot, rarely cracks with thermal expansion (when the shower or tub material expands or contracts with temperature changes), and lasts longer (40 or more years). However, it doesn’t take paint well and is about 10 percent more expensive than the alternative. - **Siliconized latex/acrylic caulk**, on the other hand, is easier to apply and correct than sticky pure silicone, which can be a *real* pain if you make a mistake during application. But it’s less moisture resistant and more likely to crack with thermal expansion, so a caulk job will be more short lived (30 to 40 years). ### Packaging Options Caulk is sold in small squeeze tubes or large cylindrical cartridges, each type suited for different scale projects and requiring a unique application. Generally, cartridges are suited for large caulking jobs, such as sealing the perimeter of a tub, as they contain more caulk by volume and afford more precise application. But they must be loaded into a [caulking gun]() and dispensed by pressing down on the gun’s trigger. Squeeze tubes are better for small-scale projects, such as filling a crack in the shower floor. The caulk can easily be applied by hand with a simple squeeze of the tube, but it has a smaller coverage area because there’s less of it by volume. ### Mildew and Mold Prevention Most pure silicone and siliconized latex/acrylic caulks are formulated with mildewcides and fungicides (chemicals that destroy mildew or fungus, respectively) to minimize the formation of stain-causing mildew or mold on the caulk. For a rot-proof caulk job, check the packaging for the terms “for bath,” “mildew-proof,” or “mold-proof,” along with the number of years the caulk can be expected to hold up to mildew and mold. ### Color Choices Both pure silicone and siliconized latex caulk are sold in a variety of colors, including clear, white, cream, and brown. Painting over caulks labeled “paintable” gives you even more color options. Clear caulk, the most versatile choice, blends into showers and tubs that range in color from light to dark; it’s your best option if you want to ensure that there is no contrast between the color of the caulk and the shower or tub. White caulk, which pairs well with most shower and tub colors, is a good option if you’re caulking a white shower or a tub or have darker fixtures and don’t mind a color contrast between the caulk and the shower or the tub. ### Dry and Cure Times Pay attention to two time frames listed on the caulk package: [dry time and cure time](). Dry time refers to how long it takes for the caulk to dry to the touch, whereas the cure time refers to when the caulk will fully set and be ready for use and exposure to water. Pure silicone and siliconized latex/acrylic caulks have similar dry and cure times—anywhere from half an hour to 12 hours to dry and 2 hours to 10 days to cure. If only caulking the shower or the tub in the house, choose caulks with dry and cure times on the low end of these ranges so that the bath won’t be out of commission for days. ## FAQs While the hands-on reviews can be extremely helpful for many shopping for shower caulk, every situation is different. Often specific questions arise, so below are answers to some of the most popular questions about caulk for showers and tubs. ## Meet the Tester Tom Scalisi is a full-time DIY and construction writer for many of the largest websites in the industry, including BobVila.com, This Old House, Family Handyman, and Forbes as well as his own pest control blog.
