7 Un-sexy (But Essential) Bathroom Remodel Must-Haves

When it comes to a bathroom remodel, it’s easy for homeowners to get swept up in the allure of glamorous design elements – the perfect tile pattern, a stunning vanity, or that high-end, waterfall, double showerhead you’ve been eyeing. 

But as any savvy renovator knows, true bathroom bliss requires addressing a host of less-than-sexy (yet absolutely essential) details.

These parts of a bathroom remodel are the unsung heroes that lay the foundation for a space that not only looks beautiful, but also functions flawlessly for years to come.

Overlook them, and you run the risk of dealing with leaks, mold, cracked tiles, and other headaches down the line – not to mention a significant dent in your home’s value.

As you plan your upcoming bathroom remodel, this list will give you the confidence to ask the right questions, understand the significance of each line item in your quote, and to point out if any crucial element is being overlooked. 

1. Bathroom Remodel Unsung Hero #1: Waterproofing

This may seem obvious, but there’s more nuance to it than you think! 

Proper waterproofing of the shower, tub, and floor is arguably the most critical aspect of any bathroom remodel. While building codes may have minimum requirements for waterproofing, it’s worth investing in a premium system that goes above and beyond that minimum.

Why is waterproofing so important? Simply put, bathrooms are inherently damp environments. Without a robust waterproofing system in place, even the slightest crack or gap can lead to devastating water damage. 

Leaks behind the walls or under the floor can rot structural supports, promote mold growth, and wreak havoc on your home over time.

By upgrading to a high-quality waterproofing solution – such as a liquid-applied, sheet membrane, or foam-based system – you’re creating an impenetrable barrier that will protect your investment for decades. 

This extra layer of protection may not be the most exciting design element, but it gives you invaluable peace of mind.

Unsung Hero #2: Plumbing Upgrades

Outdated plumbing is a ticking time bomb, just waiting to cause you headaches down the line. 

As part of your bathroom remodel, be sure to have your contractor assess and upgrade the supply lines, drains, and fixture connections.

Updating the plumbing infrastructure ensures optimal water pressure, proper drainage, and trouble-free performance for years to come. Skimping on this essential element could lead to leaks, clogs, and other plumbing nightmares that will disrupt your daily routine and potentially cause serious water damage.

In addition to addressing the visible plumbing elements, also ask your contractor about upgrading the drainage system. Proper drainage is crucial for preventing standing water and controlling moisture levels.

Remember, your shiny new bathroom fixtures and finishes are only as good as the plumbing infrastructure that supports them.

Bathroom Remodel Unsung Hero #3: Electrical Wiring

Today’s bathrooms are filled with power-hungry appliances, smart home features, and energy-efficient lighting. To ensure your new space can handle the electrical demands, work with your contractor to upgrade the wiring as part of your remodel.

Outdated electrical systems simply may not have the capacity to support the modern amenities you’re hoping to incorporate. Overloading the circuit can lead to tripped breakers, flickering lights, and even fire hazards. Upgrading to a dedicated circuit will provide the necessary capacity to handle your bathroom’s electrical needs without compromising the rest of your home’s system.

Beyond the raw power requirements, also discuss with your contractor the placement and installation of electrical outlets, lighting fixtures, and smart home integrations. Thoughtful planning during the remodel will allow you to maximize functionality and convenience, while adhering to important safety codes.

Unsung Hero #4: Ventilation

It’s more than just smell control 💩- a high-quality, properly sized exhaust fan is an absolute essential for any bathroom remodel. 

Adequate ventilation is crucial for controlling moisture levels and preventing the buildup of mold, mildew that thrive in damp environments.

While building codes may specify minimum requirements for bathroom ventilation, these standards are often outdated and don’t account for modern lifestyles and amenities. 

An undersized or inefficient fan simply won’t be able to keep up with the moisture generated by your morning showers, weekly baths, and frequent use of the sink and vanity.

When planning your bathroom remodel, work with your contractor to select a whisper-quiet, energy-efficient exhaust fan that is properly sized for the square footage of your space. 

Don’t overlook this critical behind-the-scenes element – proper ventilation is essential for maintaining optimal indoor air quality and preventing long-term damage to your newly remodeled space.

Bathroom Remodel Unsung Hero #5: Subfloor Preparation

The foundation of your new bathroom is literally the subfloor. Proper preparation and leveling of this critical base is key for a smooth, durable tile installation that won’t crack or become uneven over time.

Many homeowners make the mistake of assuming the existing subfloor is in good condition and ready to accept new tile. 

In reality, subfloors can become warped, uneven, or structurally compromised over time, especially in high-moisture environments like bathrooms.

During your remodel, have your contractor thoroughly inspect the subfloor and make any necessary repairs or modifications. 

This may involve leveling the surface, replacing cracked or damaged boards, or even installing a new subfloor altogether. 

Skipping proper subfloor preparation is a recipe for disaster – you’ll end up with tiles that crack, shift, or become uneven, drastically shortening the lifespan of your beautiful new bathroom.

Unsung Hero #6: Tile Underlayment

While the tile itself may be the showpiece of your new space, the underlayment is the unsung hero that prevents issues like cracked tiles or squeaky floors.

A tile underlayment, such as a crack-isolation or sound-dampening membrane, serves as a flexible buffer between the subfloor and your beautiful new tile. This relatively inexpensive addition can make a world of difference in the long-term performance of your bathroom, protecting against common issues like:

– Cracked tiles due to subfloor movement or settling

– Squeaky, hollow-sounding floors

– Water penetration and damage to the subfloor

When discussing your bathroom remodel with your contractor, be sure to inquire about the type of underlayment they plan to use. 

Investing in a high-quality option may cost a bit more upfront, but it will save you a significant headache down the road.

Bathroom Remodel Unsung Hero #7: Shower Pans

Last but certainly not least, investing in a quality, pre-sloped shower pan or linear drain system is crucial for ensuring proper drainage and preventing leaks in your new bathroom.

Many homeowners make the mistake of assuming a basic shower base or curb will suffice.

In reality, improperly installed or low-quality shower pans are a common culprit behind bathroom leaks and water damage. Even the slightest gap or crack can allow water to seep through, wreaking havoc on your walls, floors, and foundation.

By upgrading to a pre-sloped, watertight shower pan or linear drain system, you’re creating an airtight barrier that will keep water exactly where it belongs – contained within the shower enclosure. 

These specialized products are engineered to provide proper drainage and prevent any leakage, giving you peace of mind and protecting the long-term integrity of your new bathroom.
