Should You Use Cement Board Beneath a Bathtub
If you’re considering a bathroom remodel or installing a new bathtub, one important question you might be asking yourself is: Should I put cement board under my tub? This is a common query among homeowners, and it’s essential to know the advantages and disadvantages before making a decision. In this article, we’ll dive into the pros and cons with a sprinkle of humor (because who said learning can’t be fun?) to help you determine whether cement board is the right choice for your tub foundation.
Understanding the Purpose of Cement Board
Before we dive into the debate, let’s get acquainted with what cement board is and why it’s used. Essentially, cement board is a durable material made from a mixture of cement and reinforcing fibers. It’s frequently used as a backer board for tile installations, providing stability and support to ensure the tiles stay securely in place over time. But does this mean it’s necessary to use cement board specifically under a bathtub? Let’s find out!
The Argument for Using Cement Board
-
Waterproofing Protection: One of the key benefits of using cement board is its ability to resist moisture. Bathrooms are naturally prone to high humidity and water exposure, making waterproofing a major concern. By installing cement board under your tub, you create an added layer of protection against potential water damage to the subfloor and surrounding areas. Think of it as a waterproof shield that keeps your bathroom dry and secure.
-
Enhanced Stability: Cement board is known for its durable and sturdy nature. By adding this material under your bathtub, you provide extra support and stability, minimizing any movement or flexing. This can be particularly beneficial if you have a cast iron tub, which tends to be heavier than other types. Plus, who wants an unnerving creaking sound every time they step into their tub? Cement board helps ensure a solid and secure foundation.
-
Preventing Mold and Mildew: Bathrooms are a breeding ground for mold and mildew. These unwanted guests thrive in moist environments and can cause both health issues and structural damage. With cement board as a protective barrier, you significantly reduce the risk of mold and mildew growth. And hey, no one wants their bathroom to turn into a scene from a horror movie, right?
The Argument against Using Cement Board
While cement board offers several advantages, it’s important to consider the potential drawbacks as well. Here are a few reasons why some people might choose not to use cement board under their tub:
-
Added Cost and Effort: Installing cement board requires extra time, effort, and expertise compared to other alternatives like using a tub liner or a mortar bed. It also entails additional costs for materials and labor. If you’re on a tight budget or prefer a simpler installation process, this could be a compelling factor to skip the cement board.
-
Existing Subfloor Quality: Before deciding on cement board, you should evaluate the condition of your subfloor. If you have a solid and moisture-resistant subfloor, it may already provide adequate support and protection for your bathtub. In such cases, cement board may not be necessary, saving you both time and money.
-
Alternative Waterproofing Options: While cement board is a tried-and-true method, there are alternative waterproofing solutions available in the market. Some newer materials and systems claim to offer comparable or even superior protection against water damage. If you’re open to exploring innovative options, it’s worth considering these alternatives to see if they meet your specific needs.
Considering the Right Choice for You
Ultimately, the decision to use cement board under your bathtub depends on various factors, including your budget, the condition of your subfloor, and personal preferences. It’s crucial to balance the benefits of waterproofing, stability, and mold prevention against the added costs and effort involved. Consulting with a professional contractor or a knowledgeable salesperson can also provide valuable insights tailored to your unique situation.
So, should you put cement board under a tub? While it may not be a one-size-fits-all answer, we hope this article has shed some light on the subject and helped you navigate this bathtub foundation conundrum. Remember, whether you choose to go the cement board route or explore other options, what matters most is creating a secure and enjoyable bathroom space for pampering yourself and belting out your favorite tunes in the shower. Happy remodeling!

FAQ: Should You Put Cement Board Under A Tub
How long should cement board screws be
When it comes to securing cement board under a tub, the length of the screws you use is crucial. Ideally, you should opt for screws that are at least 1 ¼ inches in length. This will ensure proper penetration into the subfloor, providing a sturdy foundation for your tub and preventing any unnecessary movement.
Does durock go under a tub
Indeed, durock does go under a tub! Durock is a brand of cement board that is commonly used as a reliable underlayment for various flooring applications, including tub installations. Its durable composition and water-resistant properties make it an excellent choice for reinforcing the area beneath your tub, creating a solid base that can withstand the weight and moisture over time.
What is the best flooring for a small bathroom
When it comes to small bathrooms, choosing the right flooring is crucial to make the space feel larger and more cohesive. Options such as porcelain or ceramic tiles are popular choices due to their ability to resist moisture and their wide range of designs. Another great choice is luxury vinyl plank (LVP) flooring, which mimics the appearance of hardwood while offering durability and a waterproof surface.
What is the best backer board for a shower
For shower installations, selecting the right backer board is essential. Consider using cement board with a waterproofing membrane such as Schluter Kerdi. This combination provides optimal protection against moisture in wet areas, ensuring a long-lasting and watertight shower enclosure. Remember, proper installation techniques and sealing all board joints are equally important to prevent any moisture-related issues down the line.
Can you use 1/4 cement board on floors
While 1/4 inch cement board can be used for certain wall applications, it is generally not recommended for use on floors. Thicker cement board, such as 1/2 inch, is more suitable for floors due to its increased strength and stability. Using a thicker board will help prevent damage and ensure a solid surface for your flooring material.
What is underneath a bathtub
Underneath that luxurious bathtub of yours lies a few key components. The primary support structure is typically a sturdy wooden frame, which provides a stable foundation for the tub. This frame is then commonly covered with a layer of plywood or a similar subflooring material. And don’t forget the essential plumbing and drainage systems that lurk beneath, ensuring your tub functions as both a bathing oasis and a magical portal to wash away your troubles.
Do I need a vapor barrier behind cement board in the shower
Yes, you do need a vapor barrier behind cement board in shower installations to prevent moisture from seeping into the wall cavity. Installing a vapor barrier, such as plastic sheeting, between the studs and the cement board helps to create a barrier, keeping moisture from penetrating the walls and potentially causing damage, such as mold or rot. Remember, it’s always better to be safe and dry than sorry and soggy!
Can you put vinyl flooring under a bathtub
While the idea of cozy vinyl flooring snuggled under your bathtub sounds tempting, it’s not necessary to extend the vinyl flooring beneath the tub. In fact, it’s more common and practical to have the tub placed directly on the subfloor or cement board, with the flooring surrounding the tub. This ensures a smooth and seamless transition between the tub and the rest of the floor, without any unnecessary acrobatics required to lay the vinyl flooring beneath.
Does drywall go over the tub flange
When it comes to drywall and the tub flange, they should never cross paths. The drywall should end at the edge of the tub flange but never overlap it. It’s crucial to maintain a small gap between the two to prevent any water from seeping into the wall cavity and causing damage. So remember, keep them separate like two strangers on a crowded subway.
Can you use cement board in a shower
Absolutely! Cement board is a fantastic choice for showers. Its moisture-resistant properties make it an ideal material to create a solid, durable, and reliable surface for your shower walls and even the floor. Just remember to follow proper installation practices, including sealing the board joints and applying a waterproofing membrane, to ensure your shower remains watertight and your singing concerts in the rain stay fabulous.
Should I insulate under my bathtub
Insulating under your bathtub can provide several benefits. It helps to reduce noise transmission, keeps the water warmer for longer, and prevents the tub from feeling cold. Additionally, insulating can also help with energy efficiency by reducing heat loss. So, go ahead and give your tub a warm and cozy hug with some insulation. Just don’t forget to double-check that your tub doesn’t mind the added warmth!
What do I put under my shower floor
To create a solid foundation for your shower floor, it’s best to install a pre-sloped shower pan or a shower base made of materials like fiberglass or acrylic. These pans provide proper drainage and act as a stable surface for the tile or other flooring material on top. By using the right base, you can ensure a watertight and well-supported shower floor that’s ready to withstand all your cleansing adventures.
Do you have to remove the toilet to install vinyl flooring
When installing vinyl flooring, there’s no need to say goodbye to your trusty porcelain throne. You can simply work around the toilet without removing it. By carefully cutting the vinyl to fit around the toilet base, you can maintain both the sanctity of your restroom throne and the beauty of your new vinyl flooring. Just remember to turn off the water supply and cover the toilet to keep any accidents at bay.
What do you do with a gap between the tub and cement board
Ah, the infamous gap between the tub and cement board. Fear not, for there is a simple solution! You can fill this gap with a waterproof caulk or silicone sealant. This magical substance will help seal and protect against any water infiltration, creating a neat and clean finish between your tub and cement board. Embrace the power of caulk and banish the lurking gaps!
How do you cement board around a bathtub
Cement boarding around a bathtub is like giving your tub a cozy hug. To achieve this, start by measuring and cutting the cement board to fit snugly against the walls surrounding the tub. Then, using cement board screws, secure the board in place, making sure they penetrate the studs or framing at appropriate intervals. Seal the joints with mesh tape and thinset mortar, and voilà ! Your bathtub will be cozily surrounded by sturdy cement board, awaiting delightful bubbles and warm soaks.
What kind of floor goes under a bathtub
The floor underneath your bathtub requires careful consideration. Porcelain tiles, ceramic tiles, or vinyl flooring are popular choices due to their water resistance and durability. These flooring options provide a solid foundation for your bathtub, ensuring it sits comfortably and securely upon completion. So, choose a flooring material that matches your style and enjoy worry-free bathing experiences!
How do you insulate around a bathtub
Insulating around your bathtub is like giving it a warm embrace. To accomplish this, start by fitting insulation, such as fiberglass batts or foam boards, between the studs surrounding the tub enclosure. Make sure to leave a small gap around any plumbing fixtures for accessibility. Seal all the edges with tape to create a snug insulation cocoon. Now, your bathtub will feel cozier than ever, ready to offer you a relaxing retreat from the chilly world outside.
How do you level a floor under a bathtub
Ensuring a level floor under your bathtub is essential for both structural stability and an aesthetically pleasing installation. To achieve this, start by checking the subfloor for any inconsistencies or unevenness. If necessary, shim or level the subfloor using appropriate methods such as self-leveling compound or adjustable pedestals. This will create a solid and level base for your bathtub, ensuring that you can soak in peace without any wobbling sensations.
How do you insulate behind a bathtub
Insulating behind your bathtub is like wrapping it in a warm, loving embrace. To accomplish this, first, remove any existing wall covering to expose the studs. Then, install insulation batts or foam boards between the studs, making sure they fit tightly to provide maximum thermal efficiency. Finally, reinstall the wall covering, sealing all edges and seams to create a cozy insulation barrier. Your bathtub will thank you for the extra warmth during those blissful soaks!
Which side of cement board faces out
When installing cement board, it’s important to know which side should face out. The printed side of the cement board, which typically displays the manufacturer’s information and logo, should face outward, visible for all to admire. The smooth side should face inward, making contact with the subfloor or framing. It’s all about showing off the manufacturer’s craftsmanship and keeping the rough side discreetly hidden.
Do you put flooring under the bathtub
No, dear friend, the flooring doesn’t need to go under the bathtub. Instead, the flooring should be installed around the bathtub, hugging it snugly. This creates a clean and polished appearance, ensuring that the flooring and the tub coexist harmoniously without any toe-stubbing surprises. So save yourself the backache and leave the flooring to gracefully sidestep the bathtub’s authority!
