7 External Tank Mounting Brackets For Small Kitchens

When a small kitchen feels overwhelmed by bulky external tanks, the simplest solution often involves moving them off the countertops and into organized storage. Mounting these items securely transforms cluttered workspaces into functional, efficient areas where cooking prep can finally happen without obstruction. Selecting the right bracket ensures that these essential utilities remain stable, accessible, and tucked away from the daily foot traffic of a busy household.

Sure-Mount Under-Sink Bracket: Best for Hidden Tanks

Under-sink cabinets are often wasted space, cluttered with random cleaning supplies rather than utilized for structural storage. The Sure-Mount bracket takes advantage of this dark, unused corner by lifting the tank off the floor and securing it to the interior sidewall. This keeps hoses organized and prevents the tank from shifting when reaching for other items.

Because these brackets are typically made of heavy-gauge steel, they handle the weight of water-filled tanks with ease. Installation requires careful placement to avoid plumbing lines, but the payoff is a completely clear visual space above the counter.

• Best for: Homes with minimal pantry space.
• Bottom Line: An excellent choice for keeping utility tanks out of sight while maintaining quick access for filter changes.

Hold-Tight Cabinet Door Mount: Frees Up Floor Space

When cabinet floor space is non-existent, the door itself becomes prime real estate. The Hold-Tight bracket system attaches to the interior of a standard-sized cabinet door, rotating the tank along with the cabinet swing. This keeps the tank hovering just inches from the plumbing connections, minimizing the length of tubing needed.

This mounting style requires a door made of solid wood or high-quality composite to ensure the screws hold firmly. It is important to account for the tank’s diameter, as a bulky unit might prevent the cabinet door from closing properly against the shelf.

• Best for: Apartments or kitchens with very deep, narrow cabinets.
• Bottom Line: A clever, space-saving hack that makes every square inch of the cabinet interior count.

Dura-Grip Wall-Mount Bracket: For Heavy-Duty Support

Sometimes, mounting a tank inside a cabinet simply isn’t an option due to existing pipe configurations. The Dura-Grip system is designed for direct wall mounting, typically on the wall adjacent to the sink. These brackets are engineered for industrial-grade strength, ensuring the tank stays perfectly vertical regardless of external vibrations.

Given the weight involved, these must be anchored into wall studs rather than just drywall. Using appropriate lag screws provides the structural integrity necessary for peace of mind, especially in high-traffic kitchens where bumps are inevitable.

• Best for: Large tanks or setups that require frequent maintenance.
• Bottom Line: When reliability is the absolute priority, the extra effort of drilling into studs provides the most secure hold possible.

EZ-Fit Slim Profile Bracket: Ideal for Tight Gaps

Kitchens often have awkward, narrow gaps between the sink cabinet and the dishwasher or range. The EZ-Fit bracket is designed specifically for these “dead zones,” measuring only an inch or two wider than the tank itself. This allows for a clean, professional install that doesn’t sacrifice any usable storage width.

The minimalist design relies on a tension-based strap system that secures the tank against a flat surface. While it lacks the sheer mass of heavy-duty mounts, it is more than sufficient for standard kitchen filtration or utility tanks.

• Best for: Making use of awkward architectural gaps.
• Bottom Line: A streamlined solution for tight spots where every fraction of an inch matters.

Pro-Hang Adjustable Bracket: Fits Multiple Tank Sizes

Households often upgrade their equipment over time, changing from a smaller filter tank to a larger capacity unit. The Pro-Hang bracket features a sliding arm mechanism that expands or contracts to fit various diameters. This eliminates the need to replace the mounting hardware whenever a tank is replaced.

This versatility comes at the cost of a slightly larger footprint, as the adjustable arm needs space to slide. However, for those who value long-term planning, it prevents the headache of drilling new holes every few years.

• Best for: Homeowners who anticipate future equipment changes.
• Bottom Line: It is the most adaptable option on the market, offering great value for those who like to keep their options open.

Anchor-Rite Vented Bracket: Best for Air Circulation

High-humidity environments, like those under a sink, can sometimes lead to condensation buildup behind a mounted tank. The Anchor-Rite bracket features an open, perforated frame that encourages airflow all around the tank. By keeping the unit away from the wall and allowing air to pass through, it prevents trapped moisture.

This is particularly useful in warmer climates where dampness can affect cabinet integrity over time. The design is simple, robust, and prioritizes the long-term health of the surrounding cabinetry as much as the security of the tank.

• Best for: Preventing mold or moisture damage in humid climates.
• Bottom Line: A smart choice for protecting both the tank and the cabinet surface from potential condensation.

Simple-Mount Basic Bracket: A No-Frills, Solid Hold

Not every situation requires complex adjustments or heavy-duty reinforcement. The Simple-Mount bracket provides a straightforward, U-shaped cradle that supports the base of the tank while a nylon strap secures the top. It is the most budget-friendly option and is typically installed in minutes using basic hand tools.

This bracket is the standard for a reason: it works reliably for most residential tanks without unnecessary flair. It doesn’t offer the adjustment of a pro-grade mount, but for a standard, static installation, it is perfectly adequate.

• Best for: Renters or those looking for a quick, affordable fix.
• Bottom Line: Don’t pay for features that aren’t needed; this bracket gets the job done reliably and efficiently.

How to Measure Your Space Before You Buy a Bracket

Accuracy is the difference between a five-minute installation and an afternoon of frustration. Start by measuring the physical footprint of the tank while it is full, accounting for the space needed for inlet and outlet hoses. Ensure there is at least an extra inch of clearance on all sides to allow for ease of movement.

Check the cabinet door clearance if mounting internally to ensure the tank won’t interfere with hinges or shelves. It is also wise to map out where plumbing lines currently sit, as these are the most common obstacles to a clean installation.

• Pro Tip: Use painter’s tape to mark the tank’s footprint on the wall or cabinet floor to visualize the fit before drilling any holes.

Under-Sink vs. Wall-Mount: Which Is Right for You?

Under-sink mounting is the preferred route for maintaining a seamless, clutter-free kitchen aesthetic. It hides all the “ugly” components of utility tanks, keeping the focus on the kitchen design. However, it significantly limits the storage space available for cleaning supplies or heavy mixing bowls.

Wall-mounting is often necessary if the under-sink area is already crowded with garbage disposals, instant hot water tanks, or pipe traps. While it leaves the tank visible, it preserves the precious storage capacity inside the cabinets. Consider whether the look of a visible tank matters more than the loss of interior shelf space.

• Decision Matrix: Choose under-sink if you have excess storage; choose wall-mount if your cabinets are already packed to the brim.

Key Safety Checks for a Securely Mounted Tank

A mounted tank must be immobile to prevent damage to hoses and potential leaks. Always check that the weight of the tank is fully supported by the bracket base, rather than relying on the strap to bear the load. If the tank wobbles even slightly, tighten the hardware or add shims behind the bracket.

Ensure that all tubing has enough slack to accommodate minor vibrations without pulling on the connections. Periodically inspect the mounting screws during seasonal cleaning to ensure that vibrations haven’t loosened them over time.

• Maintenance: A quick tug test every six months keeps you ahead of any potential mechanical issues.

Properly securing an external tank is a fundamental step in reclaiming a small kitchen. By choosing the right bracket based on layout, accessibility, and weight, you create a more orderly and reliable home environment. Focus on the practicalities of your space, and you will find that a well-mounted tank is one you never have to think about again.
