Do You Do the Floor First or Last in a Bathroom Remodel?

Welcome to the Kitchen and Bath Reno Guys Kitchener Waterloo blog! One of the most frequently asked questions we encounter from homeowners in Kitchener, Waterloo, and beyond is: "Do you do the floor first or last in a bathroom remodel?" It’s a great question, and the answer isn’t always straightforward. The decision depends on multiple factors—your project scope, the materials you choose, the timeline, and even your budget.

At Kitchen and Bath Reno Guys Kitchener Waterloo, we’ve completed countless bathroom renovations, and we’re here to break down the pros, cons, and best practices for both approaches. By the end of this guide, you’ll have a clear understanding of what works best for your unique bathroom remodel. Let’s dive in!

Understanding the Bathroom Remodel Process

Before we tackle the flooring question, it’s helpful to understand the typical stages of a bathroom remodel. A well-planned renovation ensures durability, functionality, and a beautiful finish. Here’s a quick overview of the process:

Demolition: Removing old fixtures, tiles, and any outdated or damaged components.

Plumbing and Electrical: Updating pipes, drains, and wiring to meet modern codes and your design needs.

Structural Changes: Adjusting walls, adding support, or modifying the layout if needed.

Walls and Waterproofing: Installing drywall, cement board, and waterproof membranes to protect against moisture.

Fixtures and Finishes: Adding the bathtub, shower, vanity, toilet, and other elements.

Flooring: Laying tiles, vinyl, or other materials to complete the space.

The order of these steps can shift, especially when it comes to flooring. So, should you install the floor first or last? Let’s explore both options in detail.

Option 1: Installing the Floor First

Laying the flooring before installing other bathroom components—such as the vanity, toilet, or bathtub—has its merits. Here’s why this approach might appeal to you:

Benefits of Flooring First

Seamless Aesthetic When you install the floor first, the tiles or other materials extend from wall to wall, creating a uniform, uninterrupted look. This is especially appealing if you’re using large-format tiles, intricate patterns, or luxury materials like natural stone. No cuts or seams around fixtures mean a cleaner, more polished appearance.

Simplified Installation Tilers love this method because they can work without navigating around a vanity, toilet, or tub. With a clear, open space, they can lay tiles faster and more precisely, potentially saving time and labor costs for your project.

Ideal for Floating Floors If you’ve chosen a floating floor—such as luxury vinyl planks, laminate, or certain engineered wood options—installing it first is often necessary. These materials need room to expand and contract with temperature and humidity changes. Pinning them down under heavy fixtures can cause buckling or gaps over time.

Future Flexibility With the floor in place first, replacing a vanity or toilet down the road is easier. You won’t need to patch or extend the flooring to cover gaps left by old fixtures, as the material already runs beneath them.

Challenges of Flooring First

While this approach has advantages, it’s not without risks:

Damage During Construction A newly laid floor is vulnerable during a remodel. Dropping a tool, dragging a heavy bathtub, or even spilling paint can scratch, crack, or stain your beautiful new tiles or vinyl.

Protection Costs To avoid damage, you’ll need to cover the floor with protective materials like plywood, cardboard, or heavy-duty drop cloths. This adds a step—and potentially a cost—to your project.

Fixture Fit Issues When fixtures like a vanity or toilet sit on top of the floor, water can seep underneath, especially if seals fail. This might lead to mold or damage over time, particularly in a wet environment like a bathroom.

Option 2: Installing the Floor Last

The alternative—installing the floor after other components are in place—is a popular choice for many bathroom remodels. Here’s why we at Kitchen and Bath Reno Guys Kitchener Waterloo often lean toward this method:

Benefits of Flooring Last

Protection During Renovation By waiting to install the floor, you shield it from the chaos of construction. Demolition, wall repairs, painting, and heavy fixture installation all happen without risking scratches, dents, or cracks on your new flooring. This can save you from costly repairs or replacements.

Precise Fit and Finish Laying the floor last allows tiles or other materials to be cut precisely around the vanity, toilet flange, bathtub, or shower base. This creates tight, clean edges that enhance the look and help prevent water from seeping under fixtures—a critical concern in a bathroom.

Easier Adjustments During a remodel, you might need to tweak plumbing, adjust walls, or reposition fixtures. If the floor isn’t yet installed, these changes won’t damage or disrupt an already-finished surface. This flexibility can be a lifesaver if unexpected issues arise.

Better Waterproofing With the floor installed last, you can ensure walls and waterproofing systems (like membranes or backer boards) extend down to meet the flooring. This overlap creates a stronger barrier against moisture, a must for any bathroom.

Challenges of Flooring Last

This approach isn’t perfect either. Here are some potential drawbacks:

Fixture Removal If the vanity, toilet, or bathtub is already installed, they may need to be lifted or temporarily removed to lay the floor properly. This can add labor time and cost to your remodel.

Visible Cuts Tiles or materials cut to fit around fixtures might show edges that disrupt the seamless look some homeowners prefer. Skilled installers can minimize this, but it’s a consideration.

Height Adjustments Installing the floor last raises the floor level slightly, which might affect the height of your vanity or toilet. You may need spacers or adjustments to ensure everything aligns correctly.

What Do the Experts Recommend?

At Kitchen and Bath Reno Guys Kitchener Waterloo, we generally advise installing the floor last for most bathroom remodels. Here’s why this approach often wins out:

Maximum Protection A bathroom remodel involves heavy tools, fixtures, and messy tasks like grouting or painting. Waiting to lay the floor keeps it pristine, saving you stress and money.

Superior Water Resistance In a bathroom, water is the enemy. Installing the floor last allows us to cut tiles or vinyl to fit tightly around fixtures, creating a seal that keeps moisture out. We also ensure waterproofing from the walls extends properly to meet the floor, bolstering durability.

Flexibility for Changes Renovations can be unpredictable. Plumbing leaks, wall repairs, or design tweaks are easier to handle without a finished floor in the way. This approach gives us room to perfect every detail.

Professional Finish Our experienced team in Kitchener and Waterloo knows how to cut and install flooring for a flawless fit around your vanity, toilet, and tub. The result is a polished, cohesive look that elevates your bathroom.

When to Install the Floor First?

That said, there are exceptions. If you’re using large-format tiles, a complex mosaic pattern, or a floating floor, installing the floor first might be the better call. For example:

Large Tiles: Cutting big tiles around fixtures can be tricky and may ruin the aesthetic. Laying them first ensures a consistent pattern.

Floating Floors: Vinyl planks or laminate need to float freely, so they’re best installed before heavy fixtures anchor them down.

Custom Designs: If your vision includes a unique floor design that demands a seamless flow, starting with the floor might be necessary.

We’ll assess your project—considering your materials, layout, and goals—to recommend the best sequence. No two bathrooms are alike, and our tailored approach ensures the best outcome.

Additional Considerations for Your Remodel

The floor-first-or-last debate isn’t the only factor in a successful bathroom remodel. Here are a few more tips from Kitchen and Bath Reno Guys Kitchener Waterloo to keep in mind:

Material Choice Your flooring material impacts the decision. Ceramic or porcelain tiles are durable and water-resistant, making them ideal for bathrooms. Vinyl is budget-friendly and versatile. Natural stone looks stunning but requires sealing. Discuss options with us to find the perfect fit.

Budget and Timeline Installing the floor last might add a step (like lifting fixtures), increasing costs slightly. Conversely, flooring first requires protective measures. We’ll help you balance quality, cost, and timing for your Kitchener or Waterloo home.

Waterproofing Bathrooms demand robust waterproofing. Whether the floor goes in first or last, we ensure walls, shower areas, and subfloors have proper membranes or backer boards to prevent leaks and mold.

Professional Expertise DIY can be tempting, but a bathroom remodel involves plumbing, electrical, and precise installation. Mistakes can lead to leaks, damage, or code violations. Our skilled team brings years of experience to get it right the first time.

3D-Printed Blood Vessels: The Tech Just Became Scalable

By Greg Hurst and Matt Gelber.

This article was published on Medium.

The Problem: Making Vasculature is Hard!

It sounds simple enough — all of your cells require a constant supply of oxygen. Your lungs extract it from the air and your blood carries it all around your body through a vascular network comprising thousands of miles of veins and arteries. If your heart doesn’t beat at least once every couple seconds, your brain doesn’t receive enough oxygen-rich blood to maintain consciousness.

We don’t understand super high-level biological phenomena like consciousness. We can’t engineer a conscious array of cells, or even of transistors. But we understand pretty well the vasculature that supports consciousness. It’s a series of tubes. Literally. And it may be that if we can make the tubes and deliver oxygen to a sufficiently large population of cells, we can make some cool things happen. A conscious brain is a long shot, a functional piece of liver or kidney decidedly less so.

The problem is, making vasculature is hard. Cells in a dish do self-organize to an extent, but we don’t understand such systems well enough to tell a bunch of cells to grow into a vascularized organ.

An alternative means of generating physiological structure’s blood vessels is a bit cruder — design the structure you want, then make a robot that can physically place the cells and the vessels where you want them. We call this bioprinting. A major hurdle with bioprinting is the fact that, while the printer is working, the cells that have been printed are slowly dying from lack of oxygen. For really big, complex tissues, you either need a way to supply oxygen while you’re still printing, or you need a way to make all those blood vessels really fast.

One really fast approach was demonstrated in 2009. Researchers at Cornell used a cotton candy machine to melt-spin a pile of sugar fibers. They cast the sugar fibers in a polymer, dissolved them out with water and made a random vascular network in minutes. In 2012, researchers at Penn used a hacked desktop 3D printer to draw molten sugar fibers into a simple lattice and showed that the same sacrificial casting approach could be used deliver blood to rat liver cells in a dish, keeping them alive for weeks. Now, researchers at the University of Illinois at Urbana-Champaign have developed the ability to make these sugar fiber networks of any shape and size.

Materials Science + Mechanical Engineering + Theoretical Computer Science to the Rescue

Scaling the process isn’t just a matter of building a more precise, more expensive printer (although that is necessary). It’s a matter of choosing the right type of sugar, understanding the physical behavior of the sugar as it is printed and of telling the printing robot how to move. The problem spans materials science, mechanical engineering and theoretical computer science; it contained more than enough material for a PhD thesis, and the cells aren’t even in there yet. The materials and mechanical engineering aspects are laid out in a recent publication in Additive Manufacturing; the planning algorithm is described in a recent manuscript still under review.

Instead of conventional sugars, this printer uses isomalt, the same low-calorie sugar substitute they use to make throat lozenges. Isomalt works better than conventional sugar, mostly because it doesn’t burn like sugar does. The printer melts the isomalt and pushes it out of a tiny nozzle under pressure. Like a pen, the nozzle is used to “write” thin isomalt filaments, but in 3D. Printing speed, temperature and pressure are critical to achieving precise filaments. Right now the diameters of the filaments can be anywhere from 50 to 500 micrometers; to give some context, a human hair is about 10 micrometers thick. However, the researchers say it’s entirely possible to go bigger or smaller.

At that point it might seem like you’re done. But when you want to print a network comprising thousands of filaments, you encounter an interesting problem. You need to choose an order in which to print them. The printing process is freeform; you can move the nozzle anywhere you want. That means if you’re not careful, you can hit your sugar construct with your nozzle and destroy it.

Avoid Collisions AND Don’t Melt

Collision avoidance is a pretty common problem in robotics, so that part isn’t too hard to deal with. However, there is an additional wrinkle that is very specific to this problem. It has to do with the fact that every time you go to an existing filament and draw a new branch, you melt the material at the joint. Imagine you’re building a bridge, but every time you weld a new beam on, all the existing welds around it melt. This makes the problem a lot harder.

Without this constraint, the problem of choosing a sequence is analogous to finding your way out of the maze on the right. There are dead ends, but you can see them. You won’t get lost in them; you’ll immediately turn around. But with this particular constraint, choosing a sequence is like finding your way out of the maze on the right. The maze is big; for long sequences, it becomes, for all practical purposes, infinite.

The best you can do in this case is make an educated guess at every fork. For example, if you had a compass that pointed towards the exit, you might take the path that most nearly coincides with the direction of the needle. In some cases, there is no feasible printing sequence; the maze has no exit. More strangely still, you can’t know, at least with our current understanding of computer science, if you should give up. You know the exit exists if, and only if, you actually find it.

In order to navigate the maze and generate a printing sequence, you need an efficient algorithm as well as a fair bit of computational power. This part has become much easier recently with high-level languages such as the Wolfram Language. Says author Greg Hurst, a developer at Wolfram Research, “This problem spans many disciplines. Computational geometry is needed for collision detection, NP-complete graph problems — like finding cliques — need to be solved, and sparse matrix solvers need to be invoked thousands of times throughout. With the Wolfram Language, I was able to hammer out fast code in a matter of months.”

Here’s a Wolfram Language command to visualize nozzle-beam collisions. The red beams must be drawn after the green one to avoid contact with the blue nozzle as it draws the green beam:

Here’s the full implementation with relevant information to monitor the progress:

What’s Next?

So the problems of turning a design into a set of printer instructions, and of having a printer that is sufficiently precise into execute them, are more or less solved. This doesn’t mean that 3D-printed organs are just around the corner. Just pouring a bunch of liver cells around a vascular mold doesn’t give you a functional liver. You need to make the cells to grow and organize the same way they do in your body.

Cells respond to the chemical and mechanical properties of their environment, and successfully recapitulating tissue requires tailoring these parameters as well. But printing vasculature is a very important step, because without it, everything dies. Now we can start tweaking the environment without worrying so much about the all-important blood vessels.

Today, we have sugar bunnies. Tomorrow, we might have miniature organs on a chip that we use to test new drugs. In several years, who knows. Maybe we’ll be able to replace a failing heart with a patient-specific replica. Maybe the processor in your computer will be replaced by a vascularized slab of neurons. We can’t yet say what the application will be, but we have the tools now to start entertaining these ideas. Stay tuned!
