Acrylic tubs are manufactured by heating a solid sheet of acrylic that is then heated to make it pliable for molding. The tub is shaped by pulling it out of the mold after the material cures. Fiberglass layers are then sprayed onto it for durability and sealed to add protection and give it a shiny finish.

Due to their manufacturing process, they are a tad bit more expensive than fiberglass tubs. They are durable, easy to install, light in weight and they don’t need a lot of maintenance. Acrylic material is mostly used to make whirlpool jets, seats, headrests including other molding details.

Feature-wise Comparison of Acrylic vs Fiberglass Bathtubs

1. Durability

Acrylic tubs are stronger and thicker than fiberglass tubs making them less prone to cracking. This means that they can be used for even 30 years. The plastic component used in manufacturing makes it the safest bathtub material.

Fiberglass bathtubs are more brittle and thinner than acrylic tubs; which translates to easy cracking and chipping.

2. Ease of Repair

As much as fiberglass is more prone to chipping and cracking, it is quite easy to repair. Minor problems in fiberglass can be re-finished. You’ll need to do some sanding, mixing, and curing but the repair kits have covered the whole process.

If you can recall, color is found in the final coats of the resin gel, so if your bathtub has significant scratches or cracks, the underlying color will show, and much care is needed to match the top coat’s color.

Acrylic has a more solid surface and its color is spread throughout the material so scratches are less obvious. Using fine-grit sandpaper, the scratches can be easily sanded away.

Cracks on the other hand can pose a bigger challenge as they may even cause leaks. The repairing process can become more complicated and the whole supporting structure may need to be checked.

3. Weight

A fiberglass tub is lighter than an acrylic tub which makes it easy to put into position and to transport especially if your bathroom space is on an upper floor.

It also requires minimal floor support.

Installing acrylic tubs can be cumbersome because they are heavier than fiberglass tubs since they are made with thicker layers of materials. Although they are lighter than other types of tubs like cast iron, they will still require a tad bit more care during installation when compared to fiberglass tubs.

4. Ease of Cleaning

Acrylic or Fiberglass Tub

It is important to maintain the shiny finish of your bathtub. Fiberglass bathtubs get this glossy look from the resin gel coat that is normally the final layer.

This makes it thinner and softer than the finish used on acrylic tubs, meaning it is prone to scratching and will not keep its shine for long.

Therefore, it is advisable to use non-abrasive cleaners so as not to damage the glossy layer.

Acrylic tubs are less prone to color loss and abrasion due to the thick material that they are made of. The glossy finish can last longer and it is not vulnerable to cleaning products. However, it is still important to use gentle cleaning products.

Q7: How can I Install a Fiberglass Tub?

Here are the steps to follow for installing a Fiberglass bathtub:

  • Get to know the space available in your bathroom before installing the tub. You could opt for a regular size or larger (soaker) bathtub based on the area you’re working with. Ensure that the wooden support is sufficient and strong enough to handle the weight of the tub.
  • Set the waste assembly or trip lever component as guided by the manufacturer’s instructions. However, leave the connections loose for repositioning.
  • The rubber should be fitted at the back of the tub. Attach the drain assembly to the bathtub’s hole and install the drain. You’ll need to apply a layer of putty at the bottom of the flange of the drain. Tightly screw them together.
  • There’s a hole at the top of the bathtub, place the trip lever assembly and fasten them using a screwdriver.
  • Place the tub in position and check if the plumbing connections are intact.
  • To fit the diverter, you will need to mark a spot from the center of the tub, drill holes from the bathtub’s back and then insert the diverter fittings into the diverter. Secure it and join the spout to the diverter using a pipe.
  • Connect the water supply lines to the diverter’s sides. In case you plan to use a shower riser, place a pipe on top of the diverter. A support block that supports the shower riser should be attached between two studs of the wall. Finally, tighten all fittings and connections to ensure there are no leakages.
