  Thetford Cassette Toilets & Holding Tanks (Cassettes)    
 

"We would definitely use motorcaravanning.co.uk 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 www.motorcaravanning.com/vehicles/waste.htm. There's also full information on the products themselves plus user manuals, parts diagrams and troubleshooting advice on the manufacturer's own website www.thetford.eu (Not the USA based thetford.com 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. From 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". New from 2016 there re retro-fit wheeled cassettes for C2-3-4 & C200 and also Fresh-up Kits now largely replace the old spare cassettes. The latest Porta Potti models are here too, ours are in white, plus some spare tanks for white and grey versions. 

New: Porta-Potti Cube & Porta-Potti Excellence: This next-generation product line consists of 2 models, the high-end luxury Porta Potti Excellence left (link to the Thetford product page) with its modern design, more homelike toilet shape, comfortable seating height, bigger bowl size and the user-friendly valve handle at side. The Porta Potti Qube (link to the Thetford product page) is the basic model with a modern refreshed design, improved valve handle system, improved carry handle of the waste holding tank and improved seating comfort. These new Porta Potti products take leisure to the next level, by offering unparalleled user comfort and excellent design. It meets the current and future desires for anyone in need of a sanitary solution that doesn’t require a connection to a drainage or water system. Both product lines are made with uncompromising quality, experience and love for leisure, this is why Thetford are able to give customers a three-year warranty.

New: Wheeled Cassettes for C2-3-4 & C200 for 2016  (pic right). Availability is as Fresh-up kits only to start with. Older sets / tanks are going short or even impossible to obtain now. Why not upgrade yours to the newer style with wheels?!  These new tanks keep the yellow fittings of the originals. And yes they do fit into the older toilets C2, C3, C4, C200s, porta-kassetts, etc!  There is a slight reduction in tank capacity (~L) but well offset by the added convenience.

Genuine Thetford Fresh-up sets. Great idea and ideal for freshening up an older or pre-owned toilet and also currently on a special offer price courtesy of Thetford. The pack includes both a new holding tank (cassette) and a new toilet seat plus some free chemicals. Available ex stock for the C200 range, C250 & C260, C2-3-4 range and the C400.  These contain genuine Thetford, genuine cassettes, as per the originals - this really is the best deal you can get, all courtesy of the special Thetford pricing; bargain!  Fresh-ups without wheels are now obsolete, the new wheeled are now in stock. Don't forget there is also our 'over 100 = Free carriage' offer.

On other pages you'll find toilet 'chemicals' both traditional Aqua-Kem and the newer greener Walex sachet products like the Bio-Pak and Porta-Pak Toilet Tabs (click).

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. Newly available in 2017 the C220 cassette (latest version od the C200 swivel bowl type. 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.

Five Tank Versions:  There are two basic Thetford Toilet types with year and model variants resulting in five tank types, the basic forms are the Bench and Swivel types as pictured right.
Earlier toilets:
Models have changed over time, the earlier bench were the C2-C3-C4 in LH & RH fit and the C200 swivel type. These originally had cassettes without wheels (but this is now changing see above). One 'holding tank' ('cassette') fits the C200 series Swivel Bowl Toilets and another type in either LH or RH fits the C2 & C3 & C4 Bench Toilets (C2/3/4). For info the C200 cassette/tank is shorter and fatter at approx 45x25x25 cm overall, including the folded spout.
Newer Toilets:
The other three types are for newer toilets and all have wheels on the tanks. One fits the new C400 bench toilet as illustrated with the green fittings - this tank has wheels and the green trim on the cassette and comes in LH or RH versions. (There is a rarer C500 type as well but we've not encountered one of those so far). The fourth main type is also in the newer style with wheels and fits the new C250/C260 swivel toilets, the latter with orange fittings, both have handles and are pictured right. The fifth type fits the latest swivel bowl C220 toilet and has blue fittings, this is the latest version of the C200 series. Please note these new wheeled cassettes do not fit the older toilets you cannot use them to 'upgrade' older units but Thetford have introduced retro-fit wheeled versions specifically to upgrade the earlier C2 & C200 toilets as Freshup kits as found below.

LH/RH info: If sitting on the toilet normally the LH version will have the cassette access door to your left, while RH will have the access/door to your right. For more information see www.thetford.eu 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.

Spares & Accessories?  All spares are available if listed by Thetford. Our regular stock of common spares as listed below is normally available for immediate despatch and pictures can be seen on this pdf. Others are ordered in from Thetford based on identified part numbers from Thetford Drawings. These can take anything from a couple of days to a week or two even a month or more at times. Example spare, 'C2 Mechanism', pictured right, these are often workshop products without instructions!
