Best Caulk for Showers: Complete Guide

Type of Shower Caulk

Shower caulks come in different types. The most common are silicone and acrylic. However, some combine silicone and acrylic to give you the best of both worlds.

Silicone sealants provide an ultra-strong, long-lasting seal. Aside from being durable, they are also more flexible and hold up well to mold and mildew. However, pure silicone sealants are non-paintable.

Acrylic or acrylic latex are water-based sealants. They, too, provide a strong seal and remarkable flexibility. Also, acrylic sealants are paintable. However, they are not as durable as their silicone counterparts.


We use the shower regularly, say once or a couple of times a day. And that makes it the wettest area in our home. Hence, for better performance, a shower caulk needs to handle the wet condition. As such, aim for a shower caulk that is 100% waterproof and with an airtight seal.


A shower caulk is not only limited to indoor use. The best caulk for showers should also handle outdoor elements. For instance, it should withstand the rain and harsh UV conditions. Also, aim for a shower caulk that has a wide service temperature. After all, it is good to have a sealant that is as effective in hot conditions as cold ones.


Flexibility is not only crucial for caulking moving fixtures, such as doors and windows. The cracks and gaps in your shower are also under constant expansion and contraction. So, to handle that, aim for a shower caulk that offers much-needed flexibility to handle movements.

Mildew & Mold Resistance

The damp conditions of the bathroom make it a safe haven for mold and mildew to flourish. Such can lead to health issues. Even more, it can leave unsightly marks in your bathroom. So, I recommend using a shower caulk that has mold and mildew treatment.

Well, mold and mildew resistance tends to vary from one shower caulk to another. The best brands provide 5-10 years of mold-free protection.

Curing Time

For those with spare showers, curing time does not sound like a big deal. However, if you have one shower, you need to give it the attention it deserves.

Well, curing time varies anywhere from 30 minutes to 3 days. Should you be in a hurry and have only one shower to use, consider a shower caulk that has less curing time. However, if you are in no hurry or have a spare bathroom, you can use sealants that take longer to cure.


Of course, you want better color coordination. So, I recommend a shower caulk that blends with your bathroom décor. For easy customization, you can settle for paintable acrylic shower caulks. However, if you want a minimalist look, clear, pure silicone sealants will suffice.


Well, the best caulk for showers should be tough enough for professional use. Yet, it should be easy enough for DIYers. After all, some of us do not want to spend extra on professional service.

For easy application, aim for thick shower caulk that does not drip or create a mess. Also, you can choose between squeeze tubes and cartridges for easy application, especially in hard-to-reach places. Squeeze tubes are pretty much for small jobs. Cartridges, on the other hand, require caulk guns. These are ideal for serious caulking jobs.
