Welcome to “Roland’s blueprints”

This blueprint is only available in German!

Here you will receive a bound, 25-page, colored construction plan with additional pictures of each construction phase on CD.


With this construction plan, anyone can individually create a toilet stool for their VW bus.

I have been using this stool on my travels for a year now and it has proven itself very well. It is particularly pleasant to use and handle thanks to the integrated full extension. There were important things to consider when planning:

Am I sitting comfortably? Due to the full extension with base plate, the toilet is approx. 5 cm away from the floor, and therefore slightly higher (I am 1.80 m)

Is it easy to empty? A toilet like this can weigh 20 kg when filled, and since it slides all the way out of the cabinet it is very easy to remove and empty.

Can I also use it at night when camping? Easy to use, thanks to the full extension - when not needed, it disappears into the cupboard and is never in the way.

Can I use the toilet drain when I'm finished? Yes, since the Porta Potti has enough space at the back, the drain can easily be opened and closed again.

The construction plan describes in detail the construction of a toilet stool for various VW models - it is flexibly attached to the VW floor rail.

The total price including building materials and camping toilet from Thetford, the Porta Potti 345, is approx. 200 euros. This includes all the plywood material, strips, sheet metal parts, full extension and all fittings.

This construction plan contains a very detailed construction description that explains step by step how exactly what is to be built. A CD with lots of pictures (of each construction phase) supports the whole thing. Everything is designed so that it can be built without a lot of workshop equipment; all parts can be obtained from hardware stores or online. All wood lists and sources of supply are indicated in the construction plan.

The stool can be used in everyday life, thanks to the full extension, as a luggage box on the bus after shopping, etc.

The position of the stool can be changed anywhere in the bus, as it can be screwed anywhere using the fastening screws on the VW floor rails!

Black faux leather was used as the seat cover for the stool, which looks very elegant.
