Bathroom Safety Zones for Shower and Tub Installations

Bathroom Safety Zones

Understanding V0, V1, V2, and V3 Zones

V0 Zone

With Bathtub or Shower Head: Inside the bathtub or shower enclosure.

Without Shower Head and with Fixed Plate: Bounded horizontally by the edges of the plate and vertically from the floor to 0.05m above the floor.

With Movable Shower Head: Bounded by a vertical plane with a 1.2m radius around the water outlet, effectively enclosing the area intended to be occupied by the user.

With Fixed Shower Head: Bounded by a vertical plane with a 0.6m radius around the shower head.

V1 Zone

Extends horizontally 2.25m from the V0 zone and vertically from the floor to 2.25m above the floor. This includes the space accessible without tools.

With Movable Shower Head: Limited by a vertical plane with a 1.2m radius from the water inlet.

With Fixed Shower Head: Limited by a vertical plane with a 0.6m radius around the shower head.

V2 Zone

Extends horizontally 0.6m from the V1 zone and vertically from the floor to 2.25m above the floor. If the ceiling exceeds 2.25m, V2 extends to the ceiling or 3m above the floor, whichever is lower.

V3 Zone

Extends horizontally 2.4m from the V2 zone and vertically from the floor to 2.25m above the floor. If the ceiling exceeds 2.25m, V3 extends to the ceiling or 3m above the floor, whichever is lower. V3 includes any space under the shower or tub accessible with a tool, provided the enclosure maintains at least IPX4 protection. This classification doesn't apply to spaces beneath hot tubs and cabins.
