Acrylic Bathtubs

Acrylic tubs are among the most popular choices for homeowners today. They are made from molded acrylic-based plastic and reinforced with fiberglass. Acrylic is lightweight, durable, and available in a wide range of colors and styles. These tubs resist chipping and cracking better than other materials. With proper care, an acrylic tub can maintain its shiny, like-new appearance for years.

Cast Iron Bathtubs

Cast iron tubs have been around for over a century. They are extremely durable and retain heat very well, keeping bath water hotter for longer. These heavy tubs are coated with porcelain enamel on the interior and exterior. While prone to chipping if struck hard, cast iron tubs will easily last 50 years or more. They come in both vintage clawfoot styles and modern integrated designs.

Porcelain Enameled Steel Bathtubs

Porcelain enamel over steel combines the strength and affordability of steel with the glossy appeal of porcelain. This type of tub offers great durability and scratch resistance. Like cast iron, enameled steel also retains heat well. The porcelain enamel interior won’t fade or discolor over time. Just note that chips in the exterior paint coat may lead to rust if not repaired. Read more about the best bathtub rust removers.

Fiberglass Bathtubs

Fiberglass bathtubs are lightweight, affordable, and easy to install. They consist of molded fiberglass reinforced with resin. Most fiberglass tubs have an acrylic top layer for extra gloss and durability. Seamless fiberglass construction makes cleaning easy since grime and dirt can’t build up in crevices. Fiberglass tubs are available in almost any color. Just be aware they scratch more easily than other materials.

Stone Bathtubs

For an ultra-luxurious bathroom, you can opt for a genuine stone bathtub hand-carved from marble, granite, or natural stone. While heavy and expensive, stone tubs create a striking, spa-like focal point in the bathroom. Each stone tub is entirely unique with natural color variations. They offer unmatched elegance, but the material is prone to staining, scratching, and cracking if not handled with extreme care.

Wooden Bathtubs

Wooden tubs have an organic, rustic feel that brings the beauty of nature into the bathroom. Most wooden tubs consist of planks sealed and bolted together, then finished with water-resistant coatings. Cedar and teak are common wood types that resist decay and moisture. Wood tubs are lightweight compared to stone or cast iron. However, they require special maintenance to preserve the wood and prevent leaks over time.

Now that you know the basic bathtub types available, it’s time to look at the key features and options for selecting your tub.

Key Features and Considerations When Choosing a Bathtub

Size and Dimensions

One of the first decisions you’ll need to make is choosing the right-sized tub for your space. Measure the bathroom carefully, and think about how much room you need to move around the tub. Standard bathtub sizes range from 60-72 inches long and 30-42 inches wide. Corner tubs can maximize space in small bathrooms. Custom sizes are an option if you need a tub to fit a challenging layout.

Consider who will be using the bathtub most too. Do you need a tub long enough to stretch out and soak? If bathing small children, a smaller tub that’s easy to reach across may be best. Know the limitations of the tub size before choosing one that seems stylish but ultimately doesn’t function well.

Installation Type

The way your bathtub will be installed is another big factor in your decision. Here are some of the most common installation types:

  • Drop-in tubs sit flush within a finished tub surround. Only the tub interior is visible. Drop-ins allow flexibility in the surrounding material.
  • Undermount tubs get installed into an opening in the countertop material so the rim is underneath the counter surface. This creates a sleek, seamless look.
  • Freestanding tubs aren’t connected to surrounding walls. They can be positioned anywhere and even become a statement piece in the room.
  • Alcove tubs nestle between three walls in a coved-out space. The front face remains exposed. This is a common installation style.

Take measurements and assess your plumbing layout before deciding if one installation type will work better than another in your space.

Material and Finish

Do you prefer the sleek, glossy look of acrylic or porcelain? Or the vintage aesthetic of a clawfoot cast iron tub? Material affects the tub’s durability, heat retention, and maintenance needs. Porcelain enamel and acrylic are easiest to keep clean and shining like new. Cast iron or wood requires more routine upkeep.

You’ll also choose between a glossy or matte finish. Glossy finishes make colors pop but show water spots and dirt more. Matte or satin finishes help hide small scuffs and scratches. Make sure to consider the tub material maintenance along with your own cleaning habits before deciding on a finish.

Bathtub Features and Accessories

Once you’ve sorted out the basics like size, installation, and material, it’s time to consider any special features you may want in your new bathtub.

Jetted Tubs

Turn your tub into a spa-like retreat with water jets. Jetted tubs circulate heated water through internal jets on the tub floor and sides. The jets propel streams of water to massage sore muscles all over your body. You can find tubs with as few as 8 all the way up to 100 jets or more. Make sure to keep the tub’s capacity in mind so there’s enough water to keep jets covered. Where the jets are placed affects what areas get massaged too. Strategically positioned jets make for the best experience.

Air Baths

For gentle, all-over body relaxation, air baths infuse heated air bubbles into the water through jets around the tub. The bubbles create an effervescent massage effect without strong streams of water. Look for air baths with different bubble intensity settings so you can adjust to your liking. Some higher-end tubs even offer programmable massage cycles. One downside is that air baths tend to be louder than typical jetted tubs.

Built-in Seats

Tubs with built-in seats allow you to sit and soak in comfort. Integrated tub seats follow the inner contours of the tub so they don’t protrude awkwardly. They often include ergonomic backrests as well. This makes bathing safer and easier for children, seniors, or anyone who wants to relax in a seated position.

Bathtub Installation Tips

Installing a new bathtub takes careful planning and execution to get right, especially if you’re renovating a bathroom. Here are your main options for getting your tub installed properly.

Hiring a Professional

The best option for most homeowners is to hire a professional plumber or contractor to handle bathtub installation. This ensures:

  • Expertise in bathroom plumbing and electrical systems
  • Precise tub measurements and placement
  • Licensed tradespeople meeting local building codes
  • Safe installation without damaging tile, walls, or fixtures
  • Knowledge of specialized equipment like jetted tubs

While hiring pros adds cost to your project, it gives you peace of mind knowing your new tub will be installed correctly the first time. Be sure to get estimates from multiple contractors before choosing one.

DIY Installation

Ambitious DIYers can tackle a straightforward bathtub installation on their own. If you know your way around plumbing and basic construction, it’s doable. Be prepared to:

  • Gather the necessary plumbing supplies like tub fillers and drain kits
  • Follow detailed installation instructions
  • Carefully measure and secure the tub in place; it must be level and well-supported
  • Avoid damaging surrounding surfaces during installation

I’d only recommend DIY tub installation for those very handy with plumbing and carpentry. You should still pull the required permits and have the work inspected once complete.

Bathtub Care and Maintenance

To keep your bathtub looking pristine and prevent issues down the road, be diligent about regular tub care and maintenance.


Give your bathtub a thorough wipe down after each use to prevent the buildup of soap scum, mildew, and grime. For most materials, a gentle, non-abrasive cleaner is safe. Baking soda and vinegar make excellent natural cleaners too.

Periodically flush out the tub drain to remove accumulated hair and other debris. You can find plastic drain snakes and enzymatic drain cleaners to break down and flush away clogs.


Check around the tub for any cracks or gaps in the caulk seals, especially at corners and edges near the floor. Water seeping behind the tub can cause unseen damage. Replacing compromised caulk helps prevent leaks and the formation of mold/mildew. Plan to re-caulk your tub every 1-2 years.


Minor chips or cracks in porcelain enamel or acrylic can often be repaired with specialized filler compounds. But for more significant damage or any leaks below the tub, it’s best to call in a professional plumber. Attempting to patch major issues yourself will likely worsen the damage.

Ideas for a Relaxing Bathtub Experience

After all this talk of types and features, don’t forget the main point of a bathtub – relaxation! Here are some quick ideas to enhance your bathing experience:

Bath Bombs and Bubbles

Turn your tub into a fizzy retreat with effervescent bath bombs or scented bubble baths. They transform an everyday bath into a spa-worthy escape.

Candles and Music

Set the mood with softly flickering candles and soothing music or nature sounds. Adjust lighting and acoustics to be calming and serene.

Bath Caddies

A bathtub caddy across your tub keeps bath essentials like drinks, books, and electronics right at your fingertips. No need to get out for necessities once you’re nestled in.

Plush Robes and Towels

Treat yourself to super soft robes and towels to bundle up in post-bath. Choose breathable fabrics that envelop you in comfort.

Reading Nook

Curate a cozy reading spot near your tub to relax with a book and unwind before or after a soak. Add a comfy chair, side table, and lamp.


There you have it – everything you need to know about choosing, installing, and enjoying a new bathtub in your home. Take time to consider the options and plan your perfect tub oasis. With the right tub and accessories, you can make your bathroom not just functional but also a relaxing retreat. I hope this guide gives you the confidence to pick out your dream bathtub. Happy soaking!
