What to Put Under Vinyl Plank Flooring in a Bathroom

Installing vinyl plank flooring in a bathroom can be a great way to add style and durability to your space. However, it's essential to ensure you have the right underlayment beneath your flooring to prevent moisture damage and ensure the longevity of your new floor.

Why Do I Need an Underlayment?

An underlayment provides a barrier between your subfloor and vinyl plank flooring, serving several crucial functions:

Moisture Protection: Bathrooms are prone to moisture, so an underlayment with moisture-resistant properties can help protect your subfloor from water damage.
Sound Absorption: A thick underlayment can absorb sound, reducing noise transfer between floors.
Thermal Insulation: Some underlayments provide thermal insulation, making your bathroom more comfortable to walk on and reducing heat loss.
Leveling: An underlayment can help level out imperfections in your subfloor, providing a smooth surface for your vinyl plank flooring.

Types of Underlayment for Vinyl Plank Flooring in Bathrooms

There are several types of underlayment suitable for vinyl plank flooring in bathrooms:

Cork: Cork is a natural material with excellent moisture resistance, sound absorption, and thermal insulation properties.
Rubber: Rubber underlayment is highly moisture-resistant and provides good sound insulation.
Foam: Foam underlayment comes in various types, including polyethylene (PE), polystyrene (PS), and ethylene propylene diene monomer (EPDM). It offers good moisture resistance and sound absorption.
Combination: Some underlayments combine different materials, such as cork and foam, to provide a combination of benefits.

Choosing the Right Thickness

The thickness of your underlayment will depend on the type of flooring you choose and the condition of your subfloor:

Thin Underlayment (2-6mm): Suitable for smooth subfloors and thinner vinyl plank flooring.
Medium Underlayment (6-12mm): Provides more cushioning and sound absorption, suitable for uneven subfloors or thicker vinyl plank flooring.
Thick Underlayment (12mm+): Offers excellent moisture protection and insulation, ideal for bathrooms with concrete subfloors or excessive moisture concerns.

Installation Tips

Here are some tips for installing an underlayment beneath vinyl plank flooring in a bathroom:

Prepare the Subfloor: Ensure your subfloor is clean, dry, and level. Repair any cracks or damage before laying the underlayment.
Roll Out the Underlayment: Unroll the underlayment in the same direction as your vinyl plank flooring.
Seal the Seams: For moisture protection, use waterproof tape or adhesive to seal the seams between underlayment sheets.
Trim the Edges: Trim the excess underlayment around the perimeter of the room using a utility knife.

Conclusion

Choosing the right underlayment for vinyl plank flooring in a bathroom is crucial to ensure the longevity of your floor and prevent moisture damage. Consider the type of underlayment, thickness, and your subfloor condition when making your decision. With proper installation, an underlayment can enhance the comfort, durability, and moisture resistance of your bathroom flooring.
