Can you lay down the portable toilets for transport?

We would not recommend it. However, yes you can transport the toilet lying down.

The toilets have a number of parts which are designed based on the toilet being in an upright position. So transporting them over a long distance may cause damage. We are unable to suggest what may happen as we have never tranpsorted them lying down.

Transporting the units lying down may result in the cabinet being marked.
