Cost to rent a portable shower depends on the size of the portable shower and whether it's a single shower or a multiple shower.
For a single portable shower it can cost $100.00 to $175.00 per day which sometimes includes delivery and setup and coming to get it as well.
But some portable shower rental places may require additional fees for the setup and delivery.
If you need a long term rental for a portable shower it can cost around $2,500.00 per month for multiple showers which is pretty expensive and could be cheaper to build a shower room.
