When it comes time to replace your bathtub, you may wonder what the best option is. There are a few factors to consider when making this decision, such as cost, durability, and how easy the tub is to clean. If you’re looking for a durable and affordable tub that’s easy to keep clean, a fiberglass tub may be the best option. Fiberglass tubs are lightweight but durable and can withstand heavy use without cracking or breaking. They’re also easy to keep clean – just a quick wipe down with a wet cloth is all it takes to keep them looking new.

Why Do You Need to Cut Fiberglass Tub? 

There are a few reasons why you might need to cut a fiberglass tub. If the tub is old or damaged, it might be necessary to cut it out and replace it with a new one. If you are remodeling your bathroom, you might also need to cut the tub to make room for a unique shower or bathtub. Whatever the reason, cutting a fiberglass tub can be a tricky process, and it’s important to take precautions to avoid injury.

Tools You Will Need

When you are ready to cut your fiberglass tub, you will need a few specific tools. You will need a saw that can easily cut through fiberglass, such as a jigsaw or circular saw. You will also need a blade specifically designed to cut fiberglass, as standard blades will not be effective. In addition, you should wear safety goggles and gloves to protect your eyes and hands from the fiberglass shards. Finally, it is important to have a sturdy surface on which to work, such as a workbench or an old table.

Preparing the Area

The first step in preparing to cut fiberglass is to ensure that you wear the proper safety gear. This includes a long-sleeved shirt, pants, closed-toe shoes, and gloves. Next, you must cut the fiberglass into the desired shape and size. You will need a sharp blade and a cutting surface to do this. Be careful not to cut yourself while cutting the fiberglass.

How to Cut Fiberglass Tub

Below we will discuss some easy steps on how to cut fiberglass safely.

Cut the Fiberglass :

The best way to cut fiberglass tubs is to use a saw. A hacksaw will work, but it is slow and tiring. A power saw is better. Cut the tub along the seam where you installed it. If you are cutting it to remove it from the wall, cut it as close to the wall as possible.

Sand Down the Edges:

Sanding the edges of a cut piece of fiberglass is an important step in ensuring the finished product is as smooth as possible. The rough edges can be dangerous, especially if they are sharp. By sanding them down, you can make them less likely to cause injury. In addition, a smooth edge is less likely to snag or tear the material it comes into contact with.

Apply Primer:

Priming a fiberglass tub before painting is important because it will help the paint adhere to the surface and last longer. A few different primers can be used, and the one you choose will depend on the type of paint you plan to use. Some primers are specifically designed for use with either oil or latex paints, while others can be used with either type.

If you are using enamel paint, it is best to use a primer specifically designed for enamel. If you are using latex paint, you can use a primer for either latex or oil paints. Be sure to follow the manufacturer’s instructions for application, and allow the primer to dry completely before painting.

Paint the Tub:

The fiberglass tub is one of the most commonly used bathtub materials. It is durable and easy to clean but can also be difficult to paint. To get the best results, you should use a primer designed for fiberglass surfaces. You can then apply a coat of paint in any color you choose.

Tips and Tricks :

When renovating your bathroom, cutting the fiberglass tub is one of the most important steps. This can be a daunting task, but you can do it relatively easily with a few tips and tricks. Here are a few things to keep in mind:

First, make sure you have the right tools for the job. You will need a jigsaw with a fine-tooth blade, a razor blade, and safety glasses.

Next, measure the area where you will be cutting and draw a line on the tub using a marker or chalk. Be precise in your measurements, as any mistakes can be difficult to fix later.

Then, use the jigsaw to cut along the line you have drawn. Make sure to go slowly and carefully so that you don’t damage the tub.


Here are some precautions to take when cutting fiberglass tubs:

1. Always wear a respirator when cutting fiberglass. The fibers released during the cutting process can be harmful to your lungs.

2. Make sure the area is well-ventilated. The fumes from the resin can be toxic.

3. Use a saw blade specifically designed for cutting fiberglass. Regular saw blades can create dangerous shards that can cause injuries.

4. Wear gloves and long sleeves to protect your skin from the resin and fibers.

5. Keep a container of water nearby to dip your hands in if they come into contact with resin or fibers.

Benefits of Using Fiberglass Tub

The Disadvantage of Using Fiberglass

Fiberglass insulation has been a popular choice for home insulation for many years. It is made of small glass fibers that are blown or sprayed into walls and attics. While fiberglass is effective at preventing heat transfer, it also has some disadvantages. One major disadvantage is that fiberglass can cause health problems. The fibers can become airborne and be inhaled, which can lead to respiratory problems. Fiberglass can also irritate the skin and eyes. Additionally, fiberglass is not very effective at preventing moisture infiltration, which can lead to mold growth.

Can You Cut Fiberglass With a Sawzall?

Fiberglass can be cut with a Sawzall, but it is not recommended. Sawzalls are designed to cut through metal and other hard materials, so using one on fiberglass can result in chipped or cracked fiberglass. In addition, the heat created by the saw blade can cause the fiberglass to melt, potentially creating a fire hazard.

Is It Safe to Cut Fiberglass?

There is no easy answer to this question, as the safety of cutting fiberglass depends on a number of factors, including the type of fiberglass and the manner in which it is cut. Generally speaking, however, cutting fiberglass can be safe if proper precautions are taken. For example, using a sharp blade and wearing protective gear, such as gloves and a face shield, can help minimize the risk of injury.

How Do You Drill a Hole in Fiberglass Without Cracking It?

When it comes to drilling a hole in fiberglass, there are a few things you need to keep in mind.

  • Use the right bit size.
  • Use a lubricant to help the drill bit move through the fiberglass.
  • Go slow and steady.
  • Keep the drill bit perpendicular to the fiberglass surface.
  • Use a backer board if possible.
  • If you do crack the fiberglass, don’t worry – you can fix it.
