A bathroom remodel is one of the most rewarding home improvement projects you can take on. It boosts comfort, enhances your home’s value, and transforms a functional space into a refreshing retreat. But behind every stunning bathroom design lies a critical—and often overlooked—foundation: plumbing. Getting the plumbing right is what ensures your new bathroom works as beautifully as it looks.
At Holtkamp Plumbing, we believe that a bathroom should reflect your lifestyle and personal taste. Every project begins with a collaborative design consultation where our experienced team listens closely to your vision. From the earliest planning stages to the final polish, we guide you through each plumbing decision to ensure your bathroom plumbing remodel goes smoothly, efficiently, and without costly surprises.
Below, we’re sharing the insider tips and best practices we follow on every project—so you can plan your Bathroom Remodeling project with confidence.
Start With a Detailed Plumbing Plan
Most remodel challenges come from poor planning. Before tile is chosen or cabinets are ordered, your plumbing layout should be finalized. During our design consultation process, we help homeowners think through:
- Fixture locations and necessary pipe rerouting
- Venting and drainage requirements
- Water supply upgrades
- Optimal spacing for shower, toilet, and vanity
- Future upgrades you may want later
A clear plumbing plan prevents last-minute changes and ensures your new bathroom performs exactly how you expect. Even small adjustments—like shifting a toilet a few inches—can significantly impact labor and cost. That’s why we map out every line, pipe, and fixture before work begins.
Evaluate Your Existing Plumbing System
Older homes often have outdated plumbing systems that may not support modern bathroom features. Before starting any bathroom plumbing remodel, our team conducts a full inspection to determine whether your pipes, supply lines, and drain system are suitable.
Here’s what we typically check:
✔ Pipe Age and Material
Galvanized steel, cast iron, and polybutylene pipes often show signs of corrosion or deterioration. Replacing them during your remodel prevents future leaks that could ruin your new investment.
✔ Drain Line Slope
Incorrect drain slope leads to clogging and slow drainage—issues that are much easier to fix before the walls and floors are closed.
✔ Water Pressure
New fixtures like rainfall showers or body sprayers often require stronger water pressure or updated supply lines.
✔ Venting
Poor venting causes gurgling drains and sewer smells. Proper venting is a must for long-term performance.
By catching issues early, you avoid unexpected delays and ensure your remodel is built on a dependable plumbing foundation.
Upgrade to Water-Efficient Fixtures
Modern Bathroom Remodeling isn’t just about style—it’s also about efficiency. Today’s fixtures use less water without compromising performance, helping you save money while protecting the environment.
Examples include:
- Low-flow toilets that use 1.28 gallons or less
- Aerated faucets that maintain strong flow with reduced water usage
- Water-efficient showerheads with advanced spray patterns
- Smart shower systems that control temperature and flow
During your consultation, we help you choose fixtures that match your style, meet water-use standards, and integrate flawlessly with your new plumbing layout.
Don’t Ignore Drain Size and Venting
Drain size and venting are two plumbing elements homeowners rarely think about but play a major role in functionality.
Drain Size
A standard bathroom often uses a 1.5-inch drain for the shower, but upgrading to a 2-inch drain greatly improves drainage and reduces clogs—especially in homes where multiple family members use the bathroom.
Proper Venting
Every fixture needs the right venting to ensure wastewater flows smoothly. Without it, you may experience:
- Slow drains
- Sewer odors
- Gurgling noises
- Repeated blockages
We ensure every fixture gets adequate venting so your bathroom works seamlessly from day one.
Make Room for Shut-Off Valves
Shut-off valves are essential for quick maintenance and emergency protection. During a bathroom plumbing remodel, we always confirm that each fixture:
- Has accessible shut-off valves
- Uses updated, corrosion-resistant materials
- Provides easy control for future repairs
This simple addition can prevent extensive water damage and give you peace of mind.
Consider Relocating Fixtures Only When Necessary
Moving a toilet, tub, or shower can drastically increase project costs because it requires rerouting drainage and supply lines. At Holtkamp Plumbing, we help homeowners balance their design goals with cost-effective solutions.
Sometimes moving a fixture is completely worth it—for example, when it:
- Improves bathroom layout
- Enhances accessibility
- Allows a larger shower or bathtub
- Opens up more storage space
Our goal is to help you achieve a functional, beautiful bathroom without unnecessary expenses.
Choose Durable, High-Quality Materials
A bathroom is exposed to moisture, heat, and daily use. That’s why quality materials matter—especially in plumbing. We recommend:
- Brass or stainless steel valves
- PEX or copper supply lines
- PVC drains with proper glue and fittings
- Premium waterproofing membranes
By using reliable materials, your remodel becomes a long-term investment rather than a temporary facelift.
Waterproofing Is Non-Negotiable
Even perfect plumbing can’t protect your bathroom alone. Waterproofing prevents water from penetrating behind walls and beneath floors—where mold and structural damage can hide for years.
Our waterproofing process includes:
- Membranes for shower floors and walls
- Vapor barriers for high-moisture areas
- Properly sloped shower pans
- Leak tests before tile installation
Skipping waterproofing leads to costly repairs later, which is why we treat this step with absolute precision.
Ensure Proper Ventilation
Moisture is the silent enemy of any bathroom. Without proper ventilation, humidity builds up and leads to:
- Mold and mildew
- Peeling paint
- Musty odors
- Shortened lifespan of fixtures
During your Bathroom Remodeling, we recommend upgrading or installing an exhaust fan sized correctly for the room. New models are quiet, energy-efficient, and include humidity sensors for added convenience.
Plan for Future Needs
A great bathroom remodel looks ahead. We frequently help homeowners add plumbing features that prepare their home for future upgrades, such as:
- Additional hot water lines for spa features
- Electrical and plumbing rough-ins for future bidets
- Extra shut-off valves
- Hidden access panels
- Expanding pipe capacity for multifunction shower systems
By planning ahead, you save time and money later.

FAQs
What should I consider before starting a bathroom plumbing remodel?
Before beginning a bathroom plumbing remodel, consider the age of your existing plumbing, the location of your fixtures, water pressure requirements, drain capacity, and whether your current system can support modern upgrades. At Holtkamp Plumbing, we walk you through each of these factors during our design consultation so the remodel starts on a strong foundation.
Do I need to replace old pipes during Bathroom Remodeling?
In many cases, yes. Older pipes—especially galvanized steel, cast iron, or polybutylene—can corrode, leak, or fail under new demand. Replacing outdated pipes during a remodel helps avoid future damage and ensures long-term reliability. We evaluate the condition of your plumbing before any work begins.
How long does a bathroom plumbing remodel usually take?
The timeline depends on the complexity of your project. Simple fixture replacements may take a few days, while full Bathroom Remodeling with plumbing reconfiguration may take a couple of weeks. Our team provides a clear timeline after reviewing your design and plumbing needs so you know exactly what to expect.
Can I relocate my toilet, shower, or sink?
Yes, but relocating fixtures can significantly increase cost and project duration because it requires rerouting supply lines, drains, and venting. We help you determine whether the relocation is necessary or if your goals can be met with a more budget-friendly solution.
Will my water pressure improve after the remodel?
It can. Many Bathroom Remodeling projects include upgrading supply lines that enhance water flow, especially for homes with older or corroded piping. If you’re installing high-performance fixtures like rainfall showers or body sprayers, we’ll ensure your system can support the pressure they require.
Why is waterproofing so important during a bathroom remodel?
Proper waterproofing prevents water from penetrating walls and floors, which can lead to mold, structural damage, and costly repairs. We integrate premium waterproofing methods into every remodel to ensure your bathroom stays protected for years.
Do I need an exhaust fan if I already have a window?
Yes. While windows help with ventilation, they don’t provide consistent moisture control. A properly sized exhaust fan removes humidity more effectively and protects your bathroom from mold and mildew. We can help you choose the right fan for your space.
