The 51 Litre Flat Water Tank is a low-profile freshwater storage solution designed for campervans, motorhomes, day vans and specialist vehicle conversions where height clearance is limited.

Its slim, flat design makes it ideal for fitting under beds, seating, within furniture units or in any space where a taller tank simply won't fit. Despite its low profile, it delivers a generous 51-litre capacity, giving you plenty of water for cooking, washing and everyday onboard use.

Manufactured in the UK from WRAS-approved polyethylene, it's safe for potable water storage and built to last.

The natural semi-translucent finish lets you easily monitor water levels at a glance.
