If you’re looking for the best bathtub caulk, choosing the right product is critical to achieving excellent performance. But don’t assume that every caulk is the same. The filler in your living room isn’t subjected to the same abuse as the caulk in your shower.

12 Best Bathtub Caulks

Showers and bathtubs are two areas where caulk is needed to keep moisture out. The caulk prevents shower water from seeping behind tiles and tub surrounds and causing potential problems. Caulk also prevents mold and mildew from spreading inside your shower stall, resulting in an unsafe and unsightly setting.

A silicone caulk that remains soft and does not dry, and crumbles with time is the perfect caulk for a shower surround. These sealants come in both paintable and non-paintable forms. Our comprehensive guide will teach you which caulk is better for showers and bathrooms.

However, there are a few items to keep in mind when shopping for the right bathtub caulk. We’ve mentioned a few relevant points below.

Important Caulk Features for Showers and Bathtubs

Material Alternatives:

Siliconized latex/acrylic (latex or acrylic caulk with added silicone) adheres well to traditional shower and tub materials such as porcelain, ceramic, marble, fiberglass, and glass.

Silicon in its purest form

If you don’t plan to paint afterward, go for pure silicone for a more robust caulk work. It’s more waterproof and flexible, which means it’ll last longer and withstand rot. It often breaks less often due to thermal expansion (when the shower or tub material stretches or contracts as the temperature changes) (40 or more years). It does not take paint well and is about 10% more expensive than the alternative.

Latex/acrylic silicone caulk

It’s less toxic and simpler to work with than plain silicone, which can be a hassle to work with if you make an error. However, since it is less moisture-resistant and more likely to break due to thermal expansion, the caulk job would be less long-lasting (30 to 40 years).

Options for Packaging

Caulk is available in narrow squeeze tubes or long cylindrical cartridges, each suitable for different project sizes and use. Cartridges are best for big caulking jobs, including sealing the tub’s perimeter since they provide more caulk by volume and allow for more detailed application.

However, they must be put into a caulking gun and dispensed by pulling the cartridge’s trigger. Smaller ventures, such as covering a gap in the bathroom floor, are best suited to squeeze tubes. The caulk can be applied by hand with a quick squeezing of the hose, but the coverage area is narrower due to the lower thickness.

The best bathtub caulk is a viscous, porous paste that is mainly used to hold humidity, moisture, and debris out of joints where two surfaces intersect (e.g., where the tub meets the wall) or to fill cracks (which typically occur in the shower floor).

The garden-variety latex caulk widely used on drywall, window frames, and wooden doors will not suffice to protect your shower or tub from these attacks. The best shower or tub caulk has unique properties that make it pristine and structurally sound in the bathroom’s unique setting.

Color Schemes

Clear, ivory, cream, and brown are only a few of the colors available in pure silicone and siliconized latex caulk. You will have even more color choices by painting over “paintable” caulks. Clear caulk, the most flexible alternative, blends into light or dark showers and tubs; it’s your best chance if you want to avoid a color difference between the caulk and the shower or tub. If you’re caulking your shower or tub or have darker fixtures and don’t mind a color difference between the caulk and the shower or tub, white bathtub caulk is a decent choice. It goes well with most shower and tub colors.

Time to Dry and Cure

Pay attention to the dry time and cure time specified on the caulk box. The cure time provides when the caulk is completely set and ready for use and exposed to water, while the dry time refers to how long it takes for the caulk to dry to the touch. Dry and cure times for pure silicone and siliconized latex/acrylic caulks are identical, ranging between half an hour to 12 hours for drying and two to ten days for curing.

Choose caulks with dry and cure periods on the low end of these ranges if you’re caulking your shower or tub in the home, meaning your bath won’t be out of service for days.
