How To Install A Bathtub Liner

1. Prepare Your Bathtub

Start by checking for any form of damage and fix it accordingly. Next, get rid of any dirt or particle on your bathtub’s surface to ensure a satisfactory stick. 

Clear your bathtub by pouring denatured alcohol on your bathtub’s surface. Use a towel or other clean rug to scrub and rid the surface of any oil or scum.

2. Detach the Knobs

Get your bathtub liner in place by removing the knobs from each fixture in your bathtub. Place them together to avoid losing them in the process.

You can use this chance to replace your faucet later when you need to reattach your knobs.

3. Smear Adhesive

Smear some adhesive on the surface of your dry bathtub. Make sure that you spread it out evenly and cover the entire surface.

Any space you leave out will affect the overall effectiveness of your liner. Your choice of adhesive matters, as well. 

4. Fit Your Liner Into the Bathtub

Gently slide your bathtub liner into your shower unit. Apply a fair amount of pressure to expel all the air and ensure your liner connects to the adhesive.  

If possible, place a couple of heavy – but not too heavy – objects to aid in the application of pressure. You can also use a rubber mallet to get rid of the underlying air.

5. Apply Caulk

Apply silicone caulking over the edge of your bathtub. Doing so helps keep the moisture out, as well as promotes a clean, finished look. Allow the silicone to cure for five to ten minutes.

Clean your tub and the liner using some warm water and a mild cleansing agent. Steer clear from using scouring powder or liquid abrasives as these can permanently damage your liner. 

Your new bathtub is now ready for use. You could opt to wait at least 24 hrs before using it, but there’s no problem in using it right away if you trust that the liner is firmly in place.

Are Bathtub Liners Any Good?

If you’ve owned a bathtub before, you may have heard of something known as a bathtub liner. Liners are made from acrylic or PVC (Polyvinyl chloride). Liners are one of the many must-have bathroom items that you simply can’t do without.

Acrylic liners are mostly popular for their attractive outward form, while people like PVCs for their high durability. Whichever bathtub liner you settle for, you can rest assured that it will adequately serve its purpose. Are they any good? Yes, in so many ways.

For starters, liners enhance your bathtub’s reliability and durability. They have impressive features, including:

  • High dimensional stability
  • UV resistance
  • Good molding characteristics
  • High resistance to harsh bathroom chemicals
  • Stiffness
  • High impact resistance
  • High scratch resistance
  • And anti-microbial resistance

All these features make bathtub liners the perfect replacements for worn-out bathtubs. The installation process is pretty fast and hassle-free. 

Can You Buy A Bathtub Liner?

The best part about these liners is how affordable they are. PVC tub liners can go for as low as $890 and as high as $1000. Mind you; these prices are non-inclusive of installation.

Bathtub liners are the best replacements you can get for a bathtub in poor condition. They can save you a lot if you’re thinking of sprucing up your bathroom. 

Provided the measurement of your liner match your bathtub and you can perform the installation the right way, you don’t need to splurge on a full bathroom remodeling.

What Should I Look For In A Bathtub Liner?

First and foremost is the material. High-quality bathtub liners should be made exclusively from a gel coat. For extra reinforcement, they should also be coated with solid fiberglass materials. 

Using such liners makes it relatively more manageable for you to install on your own without much stress or hustle. Also, most of these fit perfectly, eliminating the need to replace or make any alterations to your existing tub.

Quality liners have a soft, pliable, and non-slip surface that makes them accident-proof and super comfy. 

The warranty of your preferred liner should have an extended usage period. Anywhere between one to three years is reasonable enough.

How Can I Clean and Maintain My Bathtub Liner?

Use a cloth or sponge to scrub any soap stains or mineral deposits gently. Never use wire brushes, steel wool, or metal scrapers. Even if you don’t apply pressure while cleaning, these rough tools will damage your entire setup. 

You can also enhance the luster and finish of your tub and liner by waxing using quality liquid wax.
