7 Types Of Caulk For The Bathroom - And Which To Choose

Different types of caulks do different things for your home. Silicone caulk, for example, is renowned for its durability if not for its clean application. In a similar vein, adhesive caulk, otherwise known as liquid nails, is ideal for joint repair if not long-term bathroom waterproofing.

Don't lose time on your home repair project trying to find the best caulk for your project. Let us do the hard work for you. With that in mind, your bathroom caulking options can include (but are not limited to):

1. Silicone Caulk

Looking to create a permanent, waterproof seal around your new sink or bathtub? You'll want to invest in silicone caulk. Silicone caulk has a myriad of benefits, including:

  • Inherent mold resistances
  • A longer-than-average lifespan
  • Compatibility with non-porous homing surfaces

In short, if you need to seal any gaps between your bathroom's accessories and your tile, then this is the caulk for you to use.

Unfortunately, silicone caulks aren't perfect. You won't be able to use this caulk to adhere your accessories to wood or other porous materials, as silicone is reluctant to bond with them. This caulk is also particularly messy and difficult to remove once applied, meaning that you won't be able to double back on your efforts if you make a mistake during your bathroom remodel.

That said, silicone caulks are some of the most commonly used caulks in bathroom repair and renovation. Whether you head to your local hardware store or explore Amazon's vast inventory, you'll find a silicone caulk that suits your next project's needs.

2. Acrylic Latex Caulk 

Some caulks are meant to cover smaller incisions or holes in your bathroom. Others are meant for more intensive repairs. Acrylic caulks are designed to help restore minor damage throughout your home, including your bathroom. You can use acrylic caulks to replace, repair, or accentuate materials like:

  • Wood
  • Drywall
  • Stone

Also known as "painter's caulk," acrylic caulks are designed to mesh with the existing aesthetic of your home. This caulk is easy to cover up with paint and just as easy to remove, should you wish to redo your job later down the line.

Acrylic caulk is water-resistant and simple to clean. That said, it isn't the sturdiest of caulks available to home renovators. If you're looking for material that can better seal off a tub, sink, or new array of tile, you may want to explore your other caulking options.

3. Latex Caulk

Latex caulk marries the versatility of acrylic caulk with the durability of silicone caulk. This caulk tends to be more flexible than its peers, meaning that you can more readily use it to either fill gaps between your appliances and tile or as an aestheticized adhesive alongside wood or other porous materials.

Latex caulk is waterproof and tends to have a longer-than-average lifespan, though no caulk can beat pure silicone for longevity. You can rely on this cost-effective caulk to lend both class and usability to your next bathroom repair or remodel, though be sure to keep an eye on your efforts post-job. The last thing you want to deal with is latex caulk that's taken on more water damage than you first anticipated.

4. Hybrid Caulk

Hybrid caulks tend to pick and choose the qualities that they most want to emulate. For example, manufacturers who bring these caulks to market may combine silicone and latex caulk to find some measure of flexibility alongside silicone's durability.

Because there are so many variations on hybrid caulks, take a close look at the brand that you're most interested in purchasing. Most of these combination caulks will use silicone caulk as their base, supplementing in polyurethane or other hybrids for improved variation.

At the end of the day, though, hybrid caulks tend to be on the expensive side. If you're looking for a caulk that you can essentially customize to fit your bathroom's needs, then consider what hybrid caulks your retailer of choice has in stock.

5. Adhesive Caulk

Adhesive caulk marries caulk and glue when it comes to regular bathroom repair. This caulk tends to resist the worst effects of mold and mildew but doesn't have the same texture and immediate appearance as your more traditional caulks. It is, however, relatively difficult to clean up, much in the same way that silicone caulks are. You'll want to be careful when first applying adhesive caulk and then again if your caulk ends up in need of repair - there's a good chance that you'll need to stop in the middle of a caulking job to keep adhesive caulks off of your tub or sink.

The good news is that adhesive caulk is exceptionally strong. If you're looking to seal off a joint or bind two surfaces in your bathroom together, be they porous or otherwise, then this is the caulk for you.

6. Sealant Caulk

Traditionally speaking, sealants and caulks are two separate entities. You can use caulks of all types to seal together elements in your bathroom, while sealants are used primarily for comprehensive waterproofing. What's better, then, than the chance to marry these two purposes together?

Sealant caulks tend to be more flexible than traditional caulks. Sealant caulks look and act like traditional caulk; however, they respond more positively when used with materials that tend to expand or contract.

While you can use sealant caulks on bathroom amenities, these caulks are most effective when used on windows. If you want to keep the moisture in your bathroom from negatively impacting your nearby windows, then consider using a sealant caulk to your advantage.

7. Caulk Shower Strips

If you're looking for a caulk that you can apply to your shower tiles with little to no effort, consider caulk shower strips. These strips are no mess, no fuss, and come in a wide variety of sizes. While it's more difficult to use these strips on unusually shaped tile or as a force to bind larger gaps, it still helps waterproof your bathroom and prevent debris from filling the cracks between your tub and tiles.

Unlike the other caulk types mentioned on this list, caulk shower strips are primarily made out of plastic. Their ability to wick water away from your tile and other materials is admirable, as is their ability to stick to more porous and non-porous surfaces. That said, it tends to rest on top of the gaps that you're looking to fill instead of practically filling them.

If you're looking for this kind of superficial coverage, then this cost-effective coverage is for you! If you're in the market for a more comprehensive binding solution, though, consider some of the other caulks on this list.

Variations on a Theme

For every individual caulk available to you on the market, there are even more alternatives available to you as you remodel your bathroom. Manufacturers who specialize in latex, silicone, and acrylic caulks, for example, may also choose to offer you access to a selection of colored caulks. These caulks resemble modeling clay in appearance but can add a splash of personalization or fun to any remodeling project.

Other unique kinds of caulks available for use in your bathroom include (but are not limited to):

  • Weatherproof caulk
  • Mildew and mold-resistant caulk
  • Paintable caulk
  • High-performance caulk
