Wall Aquarium Costs: What to Expect for a Built-In Marine Display

Hey folks, Hank here! I’m an avid woodworker and DIYer who always seeks unique projects to flex my skills and creativity. Lately, I’ve been fascinated by the idea of building a custom wall aquarium for my living room. A stunning aquascape could be a unique focal point and conversation starter!

But before diving in, it’s crucial to understand the costs and considerations involved with a built-in wall aquarium. After all, these aren’t your run-of-the-mill fish tanks – they require serious planning and commitment. In this post, I’ll explain everything you need to know if you’re considering constructing your in-wall underwater world. Let’s take the plunge!

What Exactly is a Built-In Wall Aquarium?

For those new to the concept, a built-in wall aquarium is a large, custom-designed fish tank that is seamlessly installed into a home’s wall. Unlike a standalone tank, a wall aquarium beautifully blends into the existing architecture and decor.

These tanks are typically rectangular or curved and made of thick, durable glass or acrylic. They can vary significantly in size, but a standard wall aquarium may hold from 30 to over 100 gallons.

How much is a built in wall aquarium

There are a few common types of built-in wall aquariums:

  • Freshwater aquariums: The most popular variety of freshwater aquariums houses tropical freshwater fish, live plants, and decor. They require less intensive maintenance than saltwater.
  • Saltwater reef aquariums: These mimic coral reef ecosystems with vibrant corals and marine fish. They require specialized care and equipment.
  • Brackish aquariums: A blend of fresh and saltwater, brackish aquariums house estuarine species that thrive in moderate salinity.

The type you choose will impact the overall cost and care requirements. But no matter which you select, a living wall aquarium makes a jaw-dropping design statement!

Why Are Wall Aquariums So Hot Right Now?

It’s no secret that wall-mounted aquariums are significant in home decor and design. Walk into any chic modern abode or expensive office space, and you’ll likely find one of these immersive underwater installations:

  • Watching the aquatic life swim about provides a relaxing, almost hypnotic visual experience. It’s like having a serene nature documentary in your own home!
  • The soothing aqua glow creates a peaceful ambiance, perfect for destressing.
  • It’s an exotic conversation starter that instantly makes any room feel more luxe.
  • The aquascape possibilities are endless! From minimalist to densely planted jungle vibes, you can customize the look.
  • They allow small spaces a substantial visual impact without taking up valuable floor area.

Thanks to advancing aquarium technology and equipment, wall-mounted tanks are also easier to maintain. The sky’s the limit for customization, too, from futuristic rimless designs to rustic wood-framed beauties.

If the water wall bug has bitten you, let’s break down everything involved so you can dive in informed!

Location, Location, Location!

It may be an obvious first step, but deciding where to install your wall aquarium is critical. This will determine the dimensions and weight the wall must support.

Though hanging a tank on any open wall may be tempting, structural integrity is no fishy business! Water weighs over 8 pounds per gallon, so a 100-gallon aquarium translates to over 800 pounds of sloshing water. Don’t forget the weight of decor, rocks, driftwood, etc.

Aim for a central, load-bearing wall on the ground floor of your home. Interior walls with wooden studs likely can’t withstand that aquatic pressure without extra reinforcement. Never hang an aquarium on drywall alone!

Ideally, choose a space where the tank can be easily viewed and enjoyed, like:

  • A living room
  • Dining room
  • Home office
  • Entryway/hallway

Avoid direct sunlight, which can encourage unwanted algae growth. Measure carefully to envision the perfect viewing angles, too.

Saltwater vs Freshwater Aquarium costs

Mapping Out the Size

Along with location, the dimensions of your wall aquarium will be a top cost determinant.

Bigger is not necessarily better (or more budget-friendly) for wall-mounted aquariums. Though jumbo tanks make a dramatic statement, they require intense specialization to install correctly.

A good rule for first-timers is to keep it under 100 gallons. My advice? Start around 50 gallons, roughly 48 x 18 x 18 inches. This allows ample aquatic real estate while remaining manageable for do-it-yourselfers.

Beyond dimensions, also consider depth. Though vast shallow tanks maximize viewing area, fish prefer deeper water columns, offering more oxygenation and swimming space.

Use the size needs of your intended livestock to guide decisions, too. Certain fish species require more generous territory. Always research before bringing home new finned friends!

Customization for Seamless Integration

In addition to size, don’t underestimate the impact of customization details in creating a seamlessly integrated wall aquarium.

First, consider the tank itself. Glass or acrylic? Rimmed or rimless? Curved or angular? There are no “right” options, only what best complements your design vision and budget.

  • Glass aquariums have a traditional vibe. Acrylics are lighter but scratch more easily.
  • Rimless looks sleek and modern. Rimmed offers more stability.
  • Estate-style wooden framing can create a stately built-in look. Or choose contemporary simplicity.

For the backdrop, neutral black makes the fish vibrantly pop. Consider matching the tank color to your wall hue, too. Blue-green, for example, can mimic ocean depths.

Aquascaping is another opportunity for customization. Do you prefer a natural, wild jungle look with driftwood and lush plants or an architecturally arranged Zen stone garden?

With thoughtful planning, you can create a truly unique underwater oasis.

Structural Considerations

Before installing any wall-mounted aquarium, the integrity of the support structure must be meticulously assessed. One leak or crack equals a wet mess on hands and floors!

Start by examining the target wall. Are there any existing electrical lines or plumbing that need to be rerouted? Mark stud locations and load-bearing points.

If the wall is concrete or brick, you need to anchor the tank securely into the holes drilled for plumbing. Wooden stud walls are trickier. For added weight distribution, you’ll probably need plywood reinforced with 2×4 braces secured to studs.

Never, ever try “winging” the structural prep work! A good general contractor can evaluate your space and suggest needed modifications so you can confidently hang that aquarium.

Breaking Down the Costs

Okay, let’s dive into the part you’re all wondering: how much does a built-in wall aquarium cost? The honest answer? It varies wildly based on size, materials, livestock, and equipment choices.

But here’s a general budgetary breakdown:

Tank Itself

The most significant upfront cost besides installation labor will be the physical aquarium.

  • A primary 50-gallon glass tank will run you $250-$500.
  • For a sizable 100+ gallon custom acrylic aquarium, expect closer to $2000-$4000 just for the tank!

Life Support System

The life support equipment (filtration, heating, lighting, pumps, etc.) can tally $500 to $1000+ for a robust system capable of handling a giant wall-mounted aquarium.


  • Live plants – $5-$20 per plant, so $100+ typically.
  • Driftwood and stones – $50-$200 depending on materials.
  • Substrate – $50+ bags of gravel or aqua soil.

Fish and Livestock

  • Freshwater fish: $5-$50 per fish, depending on species. A 50g community costs easily $ 200+.
  • Saltwater fish or coral – Often $50-$100+ per organism! Easily $1000+ in marine species.


Finally, unless you’re incredibly handy, you’ll need to hire contractors to install the tank seamlessly into the wall. This includes:

  • Structural evaluation and reinforcement ($200-$1000)
  • Physical installation and plumbing ($1000-$5000+)
  • Electrical, lighting, and equipment setup ($500-$2000)

Professional Help – Should You Hire It?

Attempting a DIY project like a wall-mounted aquarium is only advisable if you have specialized construction, electrical, and aquarium husbandry skills.

For all others, hiring a professional full-service team is strongly recommended. Otherwise, you risk shoddy installation, flood damage, or even injured livestock.

Seeking qualified help ensures:

  • Structurally sound wall reinforcement and leak-proof installation
  • Proper wiring and equipment for optimal functionality
  • Expertise in selecting thriving aquatic species for your set-up
  • Ongoing maintenance guidance and assistance

Look for licensed/bonded services with specialized experience in custom aquariums. Read reviews and ask for referrals from past clients. Also, validate that they carry insurance, just in case.

Yes, professional help adds to the cost. But it’s a small price to pay for the peace of mind of a job done right!

If DIY, How to Do It Safely

For my fellow devoted DIYers who still want to tackle this themselves, it IS possible with meticulous research and preparation.

Here are my top tips for safely installing your wall-mounted wonder:

  • Get engineer-approved plans for any structural changes. Don’t play guessing games with hundreds of gallons of water at stake.
  • Experiment first. Set up and maintain a small tank for several months to hone your aquarium skills before going big.
  • Take it slow. Don’t rush the installation. Move step-by-step to carefully assess any issues before proceeding.
  • Have a Pro on Call. Keep the number of an experienced aquarium pro handy in case of any emergencies or questions.
  • Choose beginner-friendly species. Avoid demanding or aggressive fish unsuited for first-timers. Build confidence with hardy species like guppies, tetras, or livebearers.
  • Invest in quality equipment. Don’t skimp on things like filters or heaters to save money, as this can compromise the health of your aquarium.
  • Learn to check water parameters. Test for pH, ammonia, nitrates, etc., to maintain ideal water quality.

Follow these tips, do your homework, and take it slowly. With diligence, you can safely DIY a wall-mounted aquarium. Just be ready for a challenge!

Budget-Friendly Hacks

Let’s brainstorm how we can make our dream wall aquarium idea more affordable without compromising quality or safety.

Here are my favorite budget-friendly tips:

  • Buy used equipment online. Just be sure to clean and test before adding it to your tank!
  • Use pool filter sand rather than pricy specialty aquarium substrates. It’s a fraction of the cost.
  • Scour secondhand stores, FB Marketplace, and Craigslist for discounted supplies. Boil or bleach decor to sterilize.
  • Collect local materials like driftwood to use for free. Again, properly clean and treat them first.
  • ** propagate plants from clippings** for lush growth without constantly buying new plants.
  • Choose low-light plants and fish to save money on fancy lighting equipment. Anubias, Java fern, and guppies are affordable options!
  • Design universal equipment housings that allow you to upgrade individual parts vs. replace entire systems.
  • Scale down the tank size slightly if needed to work with your budget. Focus on quality over quantity!

You can create a vibrant living wall aquarium with resourcefulness and patience, even on a budget. Just ensure you don’t sacrifice good construction or equipment to cut costs.

Financing Your Fishy Project

Even with crafty savings tactics, wall aquariums remain a severe investment. If cash flow prohibits your aqua dreams, financing can help ease the initial sting.

Consider financing options like:

  • Credit cards – Many offer 12-18 month 0% interest promotions, which you can use. Just be sure to pay off the balance in time!
  • Personal Loans – Unsecured loans through your bank are an affordable way to borrow needed funds.
  • Payment Plans – Some aquarium services offer monthly payment breakdowns that are interest-free.
  • HELOC Loans – If you have home equity, a HELOC provides access to funds at low rates.
  • Crowdfunding – For a unique project, crowdfunding sites allow you to pool money from a community.

I always recommend exhausting budget-saving tactics before taking on financing and its added costs. Make sure to calculate monthly payments to ensure they fit your budget!

But used responsibly, financing strategies let you actualize your dream aquarium sooner rather than later.
