"We would definitely use again, your customer service is first class" T&AW.

Toilets: One of our more popular site subjects! There's quite a lot of general information on mobile toilet usage and motorhome waste disposal on our main information site at There's also full information on the products themselves plus user manuals, parts diagrams and troubleshooting advice on the manufacturer's own website (Not the USA based NB!). On this webpage you'll find complete Thetford toilets for unit replacement or self-build, replacement

Thetford chemical toilets and Thetford Holding Tanks (also known as cassettes) for both bench and swivel bowl toilets along with some of the more popular spares like the spare cap with built-in measure pictured left. New for 2010 there's an excellent C200 Freshen-up Kit to rejuvenate an older or pre-owned toilet - "a simple and economic way to make the built-in Cassette toilet as good as new".

Thetford Toilet Holding Tanks: Nowadays the majority of European motorhomes and motorcaravans come already equipped with a Thetford Cassette toilet as standard. It is a fully self-contained toilet system that is built into the bathroom of motorhomes, boats, caravans or any type of recreational vehicle. Some vehicles come complete with a spare cassette for extended off-site stays and in any case many users like to replace them fairly frequently for obvious reasons!

All models have a unique waste holding tank, located underneath the toilet. This 'holding tank' or 'cassette' is removed for emptying from outside the vehicle through a small service hatch. A unique rotating pour-out spout and vent button ensure splash-free emptying. External access is what it is all about. The C200 version is illustrated in use here but we also supply cassettes for the older

C2/3/4 pictured lower right and the new wheeled versions for the C400 series bench toilets and C250 swivel toilets too. The cassette’s superbly simple service routine is handled outside the vehicle while life within goes on undisturbed. Thetford sanitation products ensure effective toilet operation and claim to offer optimum performance. Buy Now >>

LH/RH? Bench toilets are 'handed'. Left Hand or Right Hand is based on the position of the access door and this is to your left or right when sitting on the toilet. Their Cassettes / Holding Tanks are handed too. Early C400-402-403 series were fixed as LH / RH but later versions can be swapped, the C2-3-4 series cassettes are also universal and can easily be reversed. Instructions for both available by email. Many of the Fresh-up kits are universal and suitable for either hand.

Four Tank Versions: One version fits the C200 series Swivel Bowl Toilets and another fits both left

and right hand versions of the C2 & C3 & C4 Bench Toilets (C2/3/4), both toilet types are illustrated right and are the most commonly used. For info the C200 cassette/tank is shorter and fatter at approx 45x25x25 cm overall - including the folded spout.

The other two types are newer and both have wheels on the tanks. One fits the new C400 bench toilet as illustrated left - this tank has wheels and green trim on the cassette and comes in LH or RH versions. The fourth type is also in the newer style with wheels and fits the new C250 swivel toilet, both of these newer cassettes are pictured right. Please note the new wheeled cassettes do not fit the older toilets you cannot use them to 'upgrade' older units. For info: Left or right hand access for the bench toilets themselves is taken as if you were sitting on the toilet. For more information see in a new window. All cassettes are on a 1-3 working day delivery service and we often achieve the better times.

C200 Vent Option:
Some vehicles are now fitted with external holding tank / cassette venting.

These require the use of the optional vent (9a) which isn't supplied as standard. It's an easy DIY twist-in fitting but do remember to order one along with your spare cassette if this is the type that your van takes. If you're not sure have a look at our sketch left or vent pictures at right and compare these with the grey vent found near your yellow turn button. Twist & lift out. Buy Below >>>

C2 Hand Reversal or Assembly? Many cassettes are now supplied with a couple of loose parts in the box that you assemble yourself to suit LH or RH use. If you wish to see the twist on/off assembly or need to reverse a cassette hand see the simple reversal instructions plus a Thetford exploded drawing - click here .
