Thermawood vs. LVP: Waterproof Flooring Doesn't Have to Be Plastic

LVP has its place.

It is usually less expensive. It installs fast. It can make sense for rentals, quick remodels, tight budgets, or projects where somebody wants a floor they do not have to think much about.

But LVP is still plastic flooring made to look like wood.

Thermawood is real wood.

That is the biggest difference.

Thermawood is 100% solid hardwood from top to bottom. Not a picture of wood under a wear layer. Not a plastic core. Not an engineered floor with a thin layer of wood on top.

Real hardwood.

The kind you can sand, stain, repair, and refinish for generations.

LVP Is Built to Be Replaced

LVP may last a long time for what it is, but eventually it is still a floor that gets replaced.

Once it is worn, damaged, faded, buckled, or you are tired of the look, you tear it out and put something else down.

You cannot sand it.

You cannot refinish it.

You cannot bring it back to life 40, 60, or 100 years from now.

A good solid hardwood floor can outlive the people who put it in.

Thermawood gives you that same generational real-wood floor, but with improved moisture resistance and dimensional stability that open up places traditional hardwood usually could not go.

Concrete slabs.

Radiant heat.

Bathrooms.

Showers.

Coastal homes.

Kitchens.

High-moisture areas.

With the right product and installation system, these are applications where thermally modified hardwood can offer a real alternative.

That is the difference.

Waterproof Does Not Always Mean Worry-Free

LVP itself does not absorb water like wood.

But that does not mean the whole floor system is bulletproof.

When water gets underneath LVP, the padding, underlayment, adhesive, or material below it can become a problem. Moisture can get trapped under the floor. Odors can develop. Depending on the installation, seams can separate, flooring can move, or sections may have to come up anyway.

That is the part people usually do not think about when they hear "waterproof."

The plank may be plastic.

But the floor is more than just the plank.

And that is true of any flooring system, including hardwood. Proper installation and moisture management still matter.

Direct Sunlight Can Be a Problem Too

LVP can also struggle in rooms with heavy direct sunlight.

Big windows, glass doors, skylights, and rooms that get hit by the sun for hours can create substantial temperature changes.

Depending on the product and installation, that heat can cause expansion, buckling, or movement.

That is especially important in rooms with a lot of glass or homes in hot climates where the sun pounds one side of the house all day.

Thermawood is different.

It is real solid hardwood that has been thermally modified to improve dimensional stability and reduce its response to moisture.

It does not have the same plastic-core construction or heat-related behavior as LVP.

Like any natural wood, its color can change with sunlight, and installation conditions still matter.

But it gives homeowners another option beyond plastic flooring.

Waterproof Does Not Have to Mean Plastic

Many flooring products marketed as waterproof rely on vinyl, plastic, composite cores, or layered construction.

Thermawood takes a different approach.

The wood itself is changed through thermal modification.

Using heat and steam, the process alters the structure of the wood and reduces its ability to absorb moisture.

No plastic core.

No engineered layers.

No chemical preservatives used in the thermal modification process.

No surface coating responsible for creating the wood's improved moisture resistance.

Thermal modification changes the wood throughout, rather than simply applying a waterproof coating on top.

The process reduces the wood's hygroscopic behavior — its tendency to absorb and release moisture from the surrounding environment.

Less moisture absorption means substantially reduced swelling, shrinking, cupping, warping, and gapping compared with ordinary, untreated hardwood.

That's why Thermawood can perform differently from traditional solid hardwood in environments involving humidity changes, concrete slabs, radiant heat, and moisture exposure.

The wood is still real wood. It's not completely immune to movement, and a complete flooring system still needs appropriate installation and moisture protection.

But thermal modification changes what is possible with solid hardwood.

Real Wood Changes With Time — In a Good Way

A real hardwood floor does not have to look brand new forever.

It gets lived on.

It gains character.

And when it needs attention, it can be repaired, sanded, stained, refinished, and brought back.

That is why solid hardwood has been in homes for 100 years or more.

With proper care, maintenance, and installation, a Thermawood floor offers that same potential for a long service life.

LVP gives you a clean, practical look.

Thermawood gives you a real hardwood floor that can become part of the home.

Not something you automatically tear out and haul to the dump when the next style comes around.

More Places for Real Solid Hardwood

For decades, traditional solid hardwood has come with limitations.

Installers have been cautious about concrete slabs, radiant heat, bathrooms, and environments with major humidity changes.

And for good reason.

Ordinary hardwood absorbs and releases moisture, which can cause movement, cupping, shrinking, and other problems.

Thermawood changes that equation.

Through thermal modification, solid hardwood becomes more dimensionally stable and less susceptible to moisture-related movement.

That opens up applications that have traditionally been challenging for solid wood.

Concrete slabs: Thermally modified hardwood can be suitable for direct glue-down installation over properly prepared concrete using an approved adhesive system.

Radiant heat: Certain Thermawood products can be installed over compatible radiant heating systems when the installation meets the product's temperature and moisture requirements.

Bathrooms and kitchens: Improved moisture resistance makes thermally modified wood an appealing option in areas where ordinary solid hardwood may be less suitable.

Showers: Thermawood offers specialty wood solutions for shower applications when used as part of a properly designed and waterproofed shower system.

Coastal homes: Reduced moisture absorption and improved stability make thermally modified hardwood particularly interesting for environments with changing humidity.

Real solid hardwood, with possibilities that go beyond traditional flooring expectations.

Is LVP Bad?

No.

LVP works for a lot of projects.

It can be inexpensive, practical, and easy to maintain.

For some homeowners, it is exactly what they need.

But it is not real wood.

And for people who want natural grain, warmth, repairability, refinishing options, long-term value, and a floor that can still be there generations from now, it is not the same thing.

Thermawood gives you another option.

A highly moisture-resistant floor that is still 100% real solid hardwood.

Which One Makes Sense for You?

Choose LVP when you need a lower upfront cost, quick installation, and a practical floor you are comfortable replacing down the road.

Choose Thermawood when you want real solid hardwood with improved moisture resistance, greater dimensional stability, and the ability to sand, repair, and refinish your floor over time.

Water.

Humidity.

Concrete.

Radiant heat.

Bathrooms.

Kids.

Dogs.

And decades of everyday living.

Thermawood opens up a whole new world of possibilities for solid hardwood flooring.

Real wood for real life.
