31 Litre Wheel Arch Water Tank

• Utilises wasted wheel arch space efficiently
• Low-profile 31L capacity fits most vans
• Black polymer shields contents from UV
• Suitable for fresh water, greywater & chemicals
• Built-in M8 inserts for fast, secure mounting

Designed to maximise unused space, this 31-litre wheel arch water tank offers a practical solution for van users, converters, and mobile trades. Whether you're building a camper conversion or need safe, onboard water for cleaning or catering, its smart profile fits neatly over wheel arches — keeping the rest of your van bed clear and usable.

Made from UV-resistant black polymer, this tank helps to protect contents from sunlight and minimise algae growth — keeping your water fresher for longer. It’s suitable for potable drinking water, wastewater, and non-corrosive chemicals, giving you flexibility for various mobile setups.

Installation is straightforward thanks to moulded-in M8 threaded inserts, allowing you to mount securely with a fitting kit (sold separately). The tank is supplied without inlets or outlets, so you can customise it with your choice of pump, inlet, or plumbing configuration.

Ideal for campervans, pickup trucks, mobile valeting, or any situation where space is tight and water is essential. These tanks also fit brilliantly over Ford Transit Custom T7 (2023>) and the VW Transporter T7 (2025>) in both near-side and offside locations.
