Bathroom Laminate: How To Install It and Avoid Water Damage

Installing laminate flooring in a bathroom can be a great way to achieve a stylish look without breaking the bank. While laminate is often chosen for its affordability and ease of installation, many homeowners wonder, “Is laminate suitable for a bathroom?” and how to manage moisture concerns. This guide will help you understand the suitability of laminate for bathrooms, how to install it properly, and how to protect it from water exposure. We’ll cover the necessary tools, a step-by-step fitting guide, and tips for fitting around obstacles like toilets.

Is Laminate Suitable for a Bathroom?

Yes, laminate flooring can be suitable for a bathroom, but it requires careful consideration and proper installation to protect it from moisture. Bathrooms are high-moisture areas, and while laminate flooring is not entirely waterproof, many modern laminates come with water-resistant features that make them more suitable for such spaces.

Considerations for Using Laminate in a Bathroom:

1. Water Resistance:
   Laminate flooring with a water-resistant core and tight click-lock system can be suitable for bathrooms. However, it’s essential to choose a high-quality laminate designed for moisture-prone areas.

2. Proper Sealing:
   Sealing the joints and edges of laminate flooring can help prevent water from seeping through to the subfloor. Applying silicone caulk around the perimeter and around fixtures like toilets and bathtubs can provide additional protection.

3. Maintenance:
   Regular maintenance, including promptly wiping up spills and avoiding standing water, is crucial for extending the life of laminate flooring in a bathroom.

Your Biggest Risk Is Water Exposure – Here’s How To Mitigate That.

Reducing water exposure is key to ensuring the longevity of laminate flooring in a bathroom. Here are some effective strategies:

1. Seal the Joints and Edges

• Tip: Use a waterproof sealant or silicone caulk to seal the joints between laminate planks and around the perimeter of the room.
• Why It Works: Sealing the joints helps prevent water from seeping between the planks, protecting the subfloor and extending the life of the laminate.

2. Use Waterproof Underlayment

• Tip: Install a moisture-resistant or waterproof underlayment beneath the laminate flooring to provide an additional layer of protection against water.
• Why It Works: The underlayment acts as a barrier that prevents moisture from reaching the subfloor.

3. Install a Waterproof Baseboard or Moulding

• Tip: Use waterproof baseboards or mouldings around the edges of the room to prevent water from penetrating the gaps between the wall and flooring.
• Why It Works: Waterproof baseboards provide a tight seal that keeps water from entering the edges, which is often a vulnerable area for water damage.

4. Use Mats and Rugs

• Tip: Place absorbent mats or rugs near the bathtub, shower, and sink to catch any water spills and reduce the risk of standing water on the laminate floor.
• Why It Works: Mats and rugs help to absorb water, minimizing direct exposure to the laminate flooring.

5. Avoid Excessive Water When Cleaning

• Tip: Use a damp mop or microfiber cloth to clean laminate flooring instead of a soaking wet mop.
• Why It Works: Excess water can seep into the seams and damage the core of the laminate planks.

Will Sealing Laminate Flooring Joints Help Improve Its Water Resistance?

Yes, sealing laminate flooring joints can significantly improve its water resistance. Applying a waterproof sealant or using waterproof joint compound between the planks can help prevent water from penetrating the seams, which is a common point of weakness for laminate flooring in bathrooms.

Steps to Seal Laminate Flooring Joints:

1. Clean the Joints:
   Ensure that all joints are clean and free of dust and debris before applying sealant.

2. Apply Waterproof Sealant:
   Use a high-quality waterproof sealant or caulk along the seams between planks. Apply a thin, even bead and smooth it out with a finger or a tool.

3. Think About Sealing the Edges:
   Laminate is a floating floor, and it’ll expand throughout the year with temperature changes. Sealing the perimeter of the room will stop the laminate freely expanding so consider if you need this. How likely is water going to get under the skirting boards? If it’s a high chance, then seal the edges. Seal the perimeter of the room where the laminate meets walls, cabinets, or other fixtures with silicone caulk to prevent water from getting underneath the flooring.

4. Allow Proper Drying Time:
   Follow the manufacturer’s instructions for drying time to ensure a watertight seal.

8. Safety Gear (Gloves, Goggles, Knee Pads)

• Purpose: To protect yourself during installation.
• Why It’s Important: Safety gear prevents injuries and allows you to work comfortably.

How Do I Fit Laminate Flooring Around a Toilet?

Fitting laminate flooring around a toilet can be a bit tricky, but with the right approach, you can achieve a professional look:

1. Remove the Toilet – More Prep Time For Less Work Time And A Better Fit

• Method: Turn off the water supply, drain the toilet tank, and remove the toilet by unscrewing the bolts at the base. Set the toilet aside in a safe place.
• Why It Works: Removing the toilet makes it easier to cut and fit the laminate flooring precisely around the flange and allows for a seamless finish.

2. Create a Template for Cutting

• Method: Use cardboard or heavy paper to create a template of the area around the toilet flange. Transfer this template onto the laminate plank that will fit around the toilet.
  There’s another method where you mark as you go, and Chris Craft on YouTube has a great demo of it here. He’s using solid core vinyl planks, so instead of a Stanley Knife you’ll likely need something like a Coping Saw instead but the marking process is the same.
• Why It Works: Using a template ensures accurate cuts, preventing waste and ensuring a snug fit.

3. Cut the Laminate Planks to Fit

• Method: Use a jigsaw or circular saw to cut the laminate planks according to the template. Test fit the planks around the toilet flange before final installation.
