Benefits of an Acrylic Alcove Bathtub & Shower

  • An alcove tub doubles as a shower

    If your bathroom has limited space, you’ll need a soaking tub which doubles as a shower. And built-in tub shower is a space-efficient way to make this happen.  

  • Save on water

    Since an alcove tub is generally shorter than a freestanding tub or a walk-in tub, it uses less water.  

  • Spend less money

    Since alcove tubs are only finished on one side, they’re less expensive than freestanding tubs or jetted walk-in tubs. And since the drain is often in the same place as the old unit, a tub replacement is less costly since there’s no extra plumbing costs to move the drain.

  • With a skirted alcove bathtub there’s no finishing needed on the front surface

    When you get an acrylic alcove bathtub with an integral skirt, you won’t have the costs to finish the front surface with tile or decorative wall panels.

  • You’ll get a built-in storage ledge for soap and shampoo

    There never seems to be enough storage in your tub/shower! However, it’s nice to know with an alcove tub there’s a ledge around the deck (or you can say sides) to place soap and shampoo. And if you need even more room add an oversized horizontal recessed niche.

  • More space effective than a freestanding tub

    An alcove tub (unlike a freestanding tub) doesn’t need empty space around it. It’s built tight to the walls.

  • Acrylic alcove tubs with integral flanges are designed to make sure water flows into the drain, not behind the wall

    When you buy an acrylic bathtub with integral flanges, you’ll know the water will not go behind (or underneath) the tub and cause damage to the floor below.

  • An acrylic tub is warm to the touch

    Since acrylic is warm to the touch, you won’t get a ‘cold shock’ getting into the tub like you can with a cast iron unit.

  • It’s safer to get in than a freestanding tub

    Since alcove tubs are 14” to 21” high from the floor vs. freestanding tubs (which are 23” to 28” high), they’re safer to enter.

  • You can add a glass shower door

    An alcove tub is a perfect choice if you want to make sure the water from your shower stays in the tub – and doesn’t leak through grout joints on your bathroom floor.

  • Tub specialists to guide you through the process

    The Innovate Building Solutions team is focused on bath and shower remodeling. We’ll help you not only find the right tub but also match your bathtub with stylish grout free tub surround panels or a glass bathtub door. Your representative will share their personal cell phone so you can reach them directly whether it’s before, during or after the tub installation.

    If you’re looking for a high-quality, durable alcove tub that is not only built to last but has a guarantee to prove it, you’ve come to the right place. Here are the features and benefits of DuraLine alcove tubs from Innovate Building Solutions.


    • For the lower skirt models (14” and 18” high units), you’ll get a 25 year guarantee. For the 21” deep soaking alcove tub a 10 year guarantee! With cheap tubs in big-box stores and on the Internet you’re lucky if you get a 1 year guarantee and then if you tub cracks, who is going to pay the bill?
    • Thicker acrylic surface provides more durability and minimizes scratching.
    • Clean, contemporary ‘cube-shape’ design fits with bathroom trends. Say goodbye to the out-of-date design on the front of your tub today.
    • A sturdy acrylic tub. The shorter (14” and 18” deck height tubs) weigh 75 to 80 lbs. and the deeper soaking tub weighs from 104 lbs. (for the 60 x 30 size) and 106 lbs. (for the 60 x 32 size). You’ll find lower quality acrylic and fiberglass tubs DO NOT share in their product specifications weight because they’re thin, light, and flimsy.
    • Right and left hand drains eliminate the need to move plumbing in a tub replacement project.
    • Patented slim profile maximizes the space inside – yet is stronger, thicker, and more durable than other tubs.
    • With a 54 ¾” x 23 ½” to 25 ½” bathing well (for the lower deck models), you’ll have plenty of room to bathe the kids and to move around while showering.  
    • Matte finish (on shorter 14” and 18” tubs) doesn’t show scratches and compliments popular brushed nickel and matte black hardware finishes used in today’s stylish bathrooms. For the deeper soaking tub (with the 21” high skirt) you’ll get a shiny, high-gloss finish.
    • One-piece design improves strength and durability.
    • Integrated flat front skirt eliminates the cost of tile or wall panels across the front of the tub.
    • Easy to clean cast acrylic.
    • Anti-slip bottom meeting ADA (Americans with Disability Act) and ANSI (American National Standards Institute) requirements.
    • Highly resistant to staining.
    • Integral flange ensures water doesn’t leak behind your tub and onto the floor below and speeds up the installation process.
    • Overflow on all models.
    • Non-porous. Dirt won’t accumulate on the surface like fiberglass.
    • Established brands with years of bathtub innovation excellence.

    Frequently Asked Questions About Acrylic Built-In Alcove Bathtubs

    What’s the definition of an alcove replacement tub? Where’s it best to use this product?

    An alcove tub is placed inside a recessed space with 3 walls. It’s best used when you have a small bathroom, want a cost-effective bathtub system, and want the dual function of a tub shower combo. An alcove tub has a finished front side (also called an apron or skirt).

    What’s the difference between fiberglass, acrylic and cast iron tubs?

    Fiberglass alcove tubs are the cheapest on the market. They’re built by forming layers of fiber-reinforced plastic (also called FRP) into sheets which become a mold which is coated with a gel-coat resin. While fiberglass will be the cheapest priced tubs, they’re porous (which can lead to dirt getting embedded into the surface you can’t get off). They’re also prone to fading, scratching, and chipping and can warp over time.

    Acrylic alcove tubs will be more expensive than fiberglass. They have a non-porous acrylic polymer composite topcoat which is placed over fiberglass for strength underneath. These tubs are lighter than cast iron tubs, won’t chip and fade and are simple to install. Acrylic tubs are warm to the touch and moderately priced. They’re available in matte and gloss finishes.

    Cast iron alcove tubs are made by pouring molten iron into a mold which is covered with porcelain. They’re the heaviest and most expensive. They’re the coldest when you get in (although they retain the heat well) and are more difficult to install due to their weight.

    What is a tub skirt and why would I want one?

    An alcove tub has a finished front which is called a skirt (or an apron). What’s nice about an integral tub skirt is it saves on the cost of finishing the front of the tub with tile and doesn’t require any maintenance.

    When should I choose an alcove tub, a freestanding tub, drop in tub or a walk in tub?

    The reasons to choose an alcove tub is they’re less expensive, can serve multiple functions (bathing and showering) and are space efficient.

    A freestanding tub is a fun option because it can make a dramatic design difference in a room and provides a deeper soaking experience.

    Drop-in tubs are nice when you want to create an area for a recessed or corner tub which isn’t a standard size. With these odd sizes you can ‘drop in’ a tub around a deck made of tile, stone, composite, or other materials.

    Walk-in tubs are used when you have a family member who either can’t (or will struggle) stepping over the tub deck. While they’re expensive, they’re a safe option for those who are mobility challenged.

    How can I tell the difference between a cheap tub and a higher quality tub?

    It’s hard from a picture to tell the difference between a high quality and cheap alcove tub shower combo. However, here’s what you’ll want to compare to ensure you’re making a wise investment.

    1. What’s the warranty on the tub? Cheap tubs have little to no warranty. Look for tubs with long warranties (10+ years are best).
    2. What material is being used? Fiberglass tubs are cheapest, but to most people looking at a new tub they can’t tell the difference (at the surface) between a fiberglass and better quality acrylic bathtub.
    3. See how much the tub weighs. Cheaper tubs are lighter, and you won’t even see in their spec sheets how much they weigh. Sturdier tubs are thicker and will weigh 75 lbs. or more.
    FAQ #6) What wall surrounds can I use with an acrylic alcove tub? When should the backer board for my wall system be installed?

    With an acrylic tub with integral flanges, you can use any type of wall surrounds – from tile to stone to decorative grout free wall panels. The installation of the tub should ALWAYS come before installing the wall backer board (greenboard, extruded polystyrene or plywood). Note – your tile or waterproof wall panels will be set inside the integral tub flange.

    How will I know the alcove tub shower will be comfortable and fit my needs?

    The first thing you’ll want to ask is who will be using this alcove tub/shower combo. If your primary user is someone with mobility challenges who will use it for showering (or you’ll be bathing small children), a more comfortable choice will be a shallower tub (with a 14” high skirt) with a non-skid bottom. If, on the other hand, you want to enjoy relaxing soaking sessions with a nice glass of wine – then a deeper acrylic alcove tub (with an 18” or 21” high skirt) will be best.

    Pay attention before choosing any alcove tub to the size of the ‘bathing well’ (this is the area inside the tub) and water capacity. The ‘interior dimensions’ (called the bathing well) is the space available to make your tub or shower roomier. If you have a big or tall person – you want a longer and wider ‘bathing well.’

    Is a gloss or matte finish tub better?

    The advantage of a matte finish tub is it’s a better match to other matte or brushed finish materials popular in bathroom remodeling today and it’s not prone to show scratches as easily.

    The advantage of a gloss tub is it reflects more light which is nice in a small bathroom.

    Can I get a custom sized alcove tub?

    No, acrylic alcove tubs are made in standard 60” x 30” and 60” x 32” sizes. An option when you have a non-standard width or depth will be to resize the opening to fit the alcove tub. The other option is to use a drop in tub with a deck around it to fit your custom alcove space.

    How can I make sure I order the right sized bathtub replacement tub? The measurements I’m getting don’t seem to be ‘standard?’

    Since tubs are set inside ‘rough openings’ (next to the bare studs), many people assume they need a custom size (because they measure inside their existing walls which have tile or a surround system at the edges). The proper way to measure for your tub is when you’d down to the bare walls (also called the rough opening).

    If you need assistance with sizing, our Bathroom Product Specialists can help.

    Will the bottom of the tub be slippery and dangerous?

    Make sure the tub has an anti-slip bottom which meets ADA (Americans with Disability Act) and ANSI (American National Standards Institute) requirements.

    What accessories and glass doors can make my alcove tub easier to use and keep water off the floor?
