What Is a Void Under Bathtub?
If you have an older model or one that wasn’t installed correctly, there’s a good chance that there’s a void waiting to cause trouble.
The void under a bathtub is the empty space between the tub and the floor, and it could be causing more problems than you realize. When not filled, the void can lead to significant structural damage to the bathtub.
Over time, without proper support, the bottom of the tub can start to sag or crack. Imagine taking a relaxing soak only to feel your bathtub giving way under you – not so relaxing anymore.
But that’s not all – unfilled voids can also lead to water leaks. With water seeping into the gap, it can damage the floor and create a breeding ground for mold and mildew.
And unfortunately, pests like mice and insects love to set up shop in dark, undisturbed spaces like the one under your bathtub. So what’s the solution?
Filling the void with expanding foam is the best course of action. This specially designed foam will fill in those gaps and expand as it dries, creating a solid and stable base for your bathtub to sit on.
It’s like giving your tub a cozy mattress to rest on instead of leaving it on a hard, cold floor. To use expanding foam, you’ll need to remove any old caulking or sealant around the edges of the bathtub and clean out any debris or insulation that might be in the way.
Then, simply shake the can well, attach the nozzle, and carefully apply the foam around the edges of the tub. But don’t rush – it takes time for the foam to dry completely.
If you’re unsure if your bathtub has a void underneath it or not comfortable doing this yourself, consider hiring a professional plumber or contractor. They can assess the situation and take care of it for you.
Preparing the Area for Filling the Void
When dealing with filling the void under your bathtub, proper preparation is the foundation for success.
You want to make sure that the fill material adheres properly and that the bathtub remains stable and level. So, where do you start?
The first step is to remove any debris or loose material from the area around the void. This could include dirt, rocks, or old filler material.
Think of it like giving your kitchen counters a good wipe-down before cooking up a storm. Next, inspect the bathtub for any signs of damage or wear.
If there are any cracks or chips in the bathtub, these should be repaired before proceeding. Imagine fixing up a few dings on a vintage car before taking it out for a spin.
Once the area is clean and the bathtub is in good condition, it’s time to prepare the fill material. There are several different types of fill materials to choose from, including expanding foam, sand, and concrete.
If you’re using expanding foam, make sure to read the instructions carefully and follow them closely. This type of material can expand significantly, so it’s important to apply it correctly to avoid any issues later on.
Think of it like following a complex recipe for a fancy dish. If you’re using sand or concrete, mix it according to the manufacturer’s instructions and pour it into the void.
Be sure to spread it evenly and compact it as much as possible to ensure that it adheres properly. Think of it like building a sandcastle – you want to pack the sand tightly for stability.
Finally, allow your fill material to dry completely before using your bathtub again. This may take several hours or even a few days depending on the type of material used.
Using Expanding Foam to Fill the Void
Don’t worry, as there is a simple and affordable solution to these common problems- expanding foam.
Expanding foam is a versatile polyurethane foam that expands and hardens upon contact with air. This makes it the perfect material for filling the void under your bathtub.
Not only is it easy to use, but it can also be found at most home improvement stores. The process of using expanding foam to fill the void under your bathtub is simple and straightforward.
All you need to do is follow these steps:
