Can You Put Laminate Under a Bathroom Toilet And Sink?

Laminate flooring is a top choice for many homeowners because the floor is strong and durable. But can you install a laminate floor under a bathroom toilet or sink?

You can install a laminate floor under a bathroom toilet or sink but the floor has to be installed before the sink and toilet are put in place. If you are installing the toilet, sink, and laminate floor at the same time, then you should install the laminate floor first.

However, if the sink and toilet have been installed on the subfloor, then you need to remove them before laying the laminate floor. So why should the laminate floor be installed first and how do you install the floor under the bathroom sink or toilet. We have explained everything.

Can a Toilet Sit on Laminate Floor?

A toilet can sit on a laminate floor because laminate floors are usually moisture resistant. But this can only happen if the laminate floor was installed before the toilet. You should never install a toilet before the laminate floor as doing so can cause water damage and cracks in the floor.

The main factor to consider when opting for a floor for the toilet to sit on is moisture resistance. When you put a toilet on a floor, the floor will obviously see a lot of water and spills that can cause water damage if the floor isn’t water-resistant. Laminate floors however are usually moisture resistant from top to bottom due to the multiple layers of the floor. So laminate floors can be used underneath a toilet.

However, it’s important to note that a laminate floor isn’t the best option for a toilet to sit on. That’s because the laminate floor isn’t designed for bathrooms or surfaces that have constant exposure to moisture. Also, laminate floors get very slippery when wet and this can cause serious injuries in some cases

Do You Have To Remove Toilet To Install A Laminate Floor?

You need to remove the bathroom toilet or sink before installing a laminate floor. This is because laminate floors expand and contract based on temperature changes. So if the laminate floor is applied around the toilet or sink, the caulk and paddings around the sink and toilet will break and give way due to the movement of the laminate floor.

This is why it’s generally advised to remove bathroom toilets and sinks before installing a laminate floor.

If you go ahead to install a laminate floor without removing the toilet first, then you’ll start to experience leaks around the base of the toilet and sink. This is because the caulking around the base of the toilet will begin to crack and break causing water to gush out whenever you flush, wash, or use the toilet.

The water leaks can also cause water damage and rotting on the laminate flooring since laminate floors are basically made from wood.

Asides from this, removing the toilet before installing the laminate floor makes it easier to replace the toilet or fix plumbing errors. If you installed the floor after installing the toilet, then you’ll have to damage the floor to fix or replace the toilet. So whatever you do, always remove the toilet before installing a laminate floor in the bathroom.

How To Install a Laminate Floor Under Bathroom Toilet and Sink?

Installing a laminate floor under the bathroom sink or toilet can quickly turn into a difficult task if you don’t know the right steps to follow. Luckily, this guide will show you how to do this in 5 simple steps. But first, we’ll need a few tools and supplies:

  • Laminate floor underlay
  • A rubber mallet
  • Measuring Tape
  • Pencils
  • Utility knives
  • A power saw
  • Cleaning solvents
  • Clean mops and rags
  • A sealant

Here is a 5-step guide to installing a laminate floor under the bathroom toilet or sink.

1. Remove The Toilet and Sink

Remove The Toilet and Sink

The first step is to remove the toilet and bathroom sink if they have already been installed. If you don’t remove the toilet and sink, it will be difficult to get an accurate measurement of the floor.

Also, the caulking around the toilet and sink will get damaged if you don’t remove them first. I’ll advise you to contact a professional plumber to help you with this. If the toilet and sink have not been installed, then you can skip this step.

2. Set an Underlay or Subfloor

Set an Underlay or Subfloor

As explained earlier, laminate floors are usually moisture resistant from top to bottom but not from bottom to top. So putting an underlay or moisture-resistant subfloor underneath the laminate floor will protect it from water that gets underneath.

The underlay will also make the laminate planks sit and stay strong on the bathroom floor. You should ensure to choose a waterproof underlay for the laminate floor.

3. Install The Laminate Floor

The next step is to install the laminate floor on the underlay. Ensure to start the installation with the large side of the bathroom as that part is usually easier to work on.

You should know that you’ll need a joint sealant or laminate floor adhesive to make the planks stick well to the bathroom floor. This is because bathroom floors will see a lot of moisture that can easily seep under the laminate planks if the planks are not well sealed in place.

While laying the planks, ensure to do so correctly as the planks are usually designed with interlocks. You can also use a rubber mallet to hit the planks into the floor gently.

4. Trim The Laminate Floor

Trim The Laminate Floor

After installing the laminate floor, you’ll need to trim the edges of the planks that are out of place. You should pay attention to the corners of the floor and the door. You’ll also need to carve and trim the spaces where the toilet and sink will sit.

5. Reinstall The Toilet and Sink

Reinstall The Toilet and Sink

When you are done installing the laminate planks, you can call your plumber to help you reinstall the toilet and bathroom sink. Ensure to apply caulking compound around the base and pipes of the sink and toilet to prevent leaks and water damage to the laminate floor.

When you are done with this, then you have successfully installed the laminate floor in your bathroom. But will the laminate floor hold up in a bathroom? Let’s find out.

Will Laminate Flooring Hold Up in a Bathroom?

Laminate flooring will hold up in a bathroom but only if you are prepared to go the extra mile to make it work. To make a laminate floor hold up in a bathroom, you have to completely protect the flooring from water.

The biggest factor that can prevent a laminate floor from holding up in a bathroom is water. Since laminate floors are usually at least 90% wood, constant moisture will damage the laminate floor eventually. However, you can prevent this from happening by protecting the laminate floor completely from water.

To do this, you’ll need to install a waterproof underlay underneath the laminate floor. This will protect the floor from moisture beneath the floor. You should also use laminate floor adhesive while applying the laminate planks. The glue will make the planks sit tight on the floor so it becomes difficult for water to get under the floor.

The glue should also be used between the laminate planks. This will make the planks airtight so that water can’t get between them. Finally, you have to seal the laminate flooring. This might prove difficult as laminate floors can’t be sanded or refinished. But when you put a sealant over the floor, it becomes impossible for moisture to penetrate the laminate floor.

The glue, sealant, and underlay make it impossible for moisture to affect the laminate floor and this will make the floor hold up in the bathroom.

How To Protect Laminate Flooring In The Bathroom?

The following tips will protect the laminate floor in the bathroom:

Put a Waterproof Mat on the Laminate Floor

This will prevent water from getting into the laminate floor. You can also go for transparent floor covers if you don’t want to cover the look of the laminate floor. The best type of floor cover is made from transparent nylon as the cover will be waterproof and transparent enough to still reveal the laminate finish.

Mop the Laminate Floor Regularly

By mopping regularly, you will reduce the moisture content on the laminate floor. You should also do this after you take your bath.

Install the Floor Before the Toilet or Sink

This helps to prevent leaks and water damages on the laminate floor as the floor would have cured fully before the toilet is installed.

Always Use Caulking Compound Around the Sink and Toilet

This also helps to prevent leaks on the floor.

Install Bathroom Drainages

Bathroom drainages are plumbing fixtures that are installed on bathroom floors. The drainage helps to funnel water from the bathroom floor to the sewage system. Usually, bathroom floors are designed with one drainage but you can install 2 or 3 to keep water off of the laminate floor.

What To Do If You Get Water Under a Bathroom Laminate Floor?

If water gets under a bathroom laminate floor, you need to mop the water on the surface first. After doing that, you need to suck out the water under the laminate floor using a wet and dry vacuum.

You can also remove baseboards and trim around the bathroom floor and spread them out to dry. Removing the baseboards will also give you better access to suck out the water under the floor.

Final Words

In summary, laminate floors can be installed under bathroom sinks and toilets. But the flooring has to be installed before the toilet and sink. This is to prevent the flooring from breaking the caulk around the base of the toilet and sink.

You should also remember that laminate floors are not waterproof. So, you should provide waterproof covering on the floor and a subfloor below the laminate flooring to protect it from water damage.
