The right water setup can make your van more functional and better suited to how you travel. The Van Mart offers water tanks and supporting components that can help you build or upgrade a system based on your space, water needs, and overall van layout.

Types of Water Tanks We Offer

Galley Water Tank

A galley water tank is designed to store water near the kitchen or sink area of a van. Its compact form allows it to fit within cabinetry or another dedicated part of the galley. This setup can keep the water supply close to where it’s most frequently used while supporting a more straightforward plumbing layout.

Wheel Well Water Tank

The space around a van’s wheel wells can be difficult to use for conventional storage. A tank shaped around this area makes use of its irregular contours without requiring a large rectangular footprint. This makes it a practical option for builds that need to work around the van’s existing interior structure. It can also help keep the main floor area open for other features in the conversion.

Undercarriage Water Tank

An undercarriage water tank is mounted beneath the vehicle rather than inside the cabin. Its exterior placement keeps the tank separate from the main living area and can work well for layouts where interior space has already been assigned to other features. This type of setup can be especially useful for builds that favor a cleaner, less crowded interior. It reduces the need to dedicate floor space, cabinetry, or storage areas to a large water tank, leaving those parts of the cabin available for other elements of the build.

Spare Tire Water Tank

A spare tire water tank is built to fit within the space typically reserved for the vehicle’s spare wheel. This type of tank can make use of an area that may otherwise remain unused after the spare tire has been relocated or removed. Its placement keeps the tank outside the main cabin while still integrating it into the overall water system. This can make it a suitable option for builds that need additional water capacity without changing the layout of the living area.

Water System Parts and Accessories We Carry

Water Tank and Mount Kit

A combined tank and mounting kit can take some of the guesswork out of adding water storage to your van. The mounting hardware is designed to support the tank in its intended location and hold it securely once installed. Choosing a matched setup can also make it easier to plan the tank placement before moving on to the rest of the plumbing system. Therefore, before purchasing a kit, check that it’s intended for your chosen tank and mounting location.

Water Filtration and Purification Systems

Water quality can vary depending on where you refill your supply while traveling. Filtration systems can help remove unwanted particles, tastes, and odors, while purification systems provide an additional level of treatment for the stored or incoming water. The Van Mart carries both built-in and portable options, giving you different ways to incorporate water treatment into your setup.

Water System Pumps

Consistent water pressure is important when you want water to move from the tank to a sink, faucet, shower, or other fixture. A water system pump provides the pressure needed to keep that flow available when a fixture is opened. The pump you choose should match the demands of your plumbing setup and the fixtures it serves. This ensures the system can deliver water reliably without placing unnecessary strain on the pump or connected fixtures.

Electric Pumps

Powered water delivery can be useful for setups where manually dispensing water would be inconvenient. Electric pump options use an electrical supply to move water when needed, making access more convenient at camp or during everyday use. Some available products combine water storage and an electric pump in one setup, which can reduce the number of separate components required for a basic water delivery system.

Sinks

A dedicated sink gives your van a practical place for washing hands, preparing food, or cleaning dishes. Options designed for compact interiors can fit into a galley without taking over too much counter space. Certain designs also include features such as folding faucets or covers that allow the surrounding work surface to remain useful when the sink is not in use. Consider your van build before choosing a sink to ensure its size, shape, and installation requirements work with the available galley space.

Shower Port Systems, Sets, and Accessories

An onboard shower setup doesn’t always require a large permanent bathroom inside the van. Shower ports and related accessories can provide access to running water for bathing, rinsing gear, or cleaning up outside the vehicle. The Van Mart carries a range of shower components, from compact shower ports and shower sets to curtains and other supporting accessories. This variety allows you to build the setup around the amount of space and privacy you need.

Frequently Asked Questions

How do I choose the right water tank size for my van?

The right capacity depends on how much water you expect to use and how often you can refill your supply. Factors such as the number of people traveling, the length of your typical trips, and the fixtures that will draw from the tank can help you estimate how much water you’re likely to need. 

Available mounting space and the added weight of a full tank should also be considered when making your decision. A larger tank may provide more water, but it also requires more room and adds more weight to the vehicle. Compare these needs with the dimensions and capacity of each option so that you can choose a tank that suits both your travel habits and your van layout.

Can the same tank be used for fresh water or gray water?

Some water tanks are suitable for either fresh or gray water, but this depends on the individual product. The Van Mart carries options that are specifically listed for both uses, and reviewing these product details can help you confirm the intended application before installation. Avoid using a tank for a purpose that’s not specified by the manufacturer. This may create problems with water quality or the long-term performance of the system.

What components do I need for a complete van water system?

The exact components will depend on how you plan to use water in your van. A typical setup may include a water tank, pump, plumbing lines, fittings, and one or more fixtures such as a sink or shower. Filtration or purification equipment can also be added when needed. Plan the complete system before installation to make sure the individual components work together and fit within the available space.

How do I maintain and clean a campervan water system?

Inspect the system periodically for leaks, damaged connections, buildup, or other signs of wear. This helps you identify minor issues early and prevent them from affecting other parts of the system. When caring for fresh water tanks and plumbing, make sure they’re cleaned and sanitized according to the product manufacturer’s instructions. This ensures the system remains suitable for storing and delivering fresh water.

Additionally, filters require regular attention to continue working effectively. Check the recommended replacement intervals for any filtration or purification products in your setup and replace them as needed to maintain proper water treatment.

Can I install a van water system myself?

DIY installation is possible for many van water systems, especially if you’re comfortable working with plumbing, mounting hardware, and electrical components where required. However, installation difficulty varies considerably between products and layouts. Some undercarriage tanks, for example, may require drilling or specialized mounting hardware. With this in mind, review the installation instructions for your selected components beforehand and consider professional installation if the project requires tools or skills you don’t have.
