Abstract: A base for a powder coating booth, including a base structure, through which the booth is intended to rest on a floor, the base structure being configured to support a powder coating compartment of the booth. The base also includes a floor, which is supported by the base structure and which is configured to delimit the bottom of the powder coating compartment. To reduce the accumulation of residual powder, the floor includes at least one oblique panel, which is inclined with respect to the horizontal and which is configured to delimit the bottom of the powder coating compartment of the booth, whereas the at least one oblique panel is porous so as to be permeable to the air and impermeable to the residual powder resulting from powder coating an article within the powder coating compartment.
