Hi, Currently planning a DIY refit of utility room. The run of units on one side will end with a decor panel next to a freestanding washing machine. I can fix the decor panel along 3 edges (worktop cantilevered over the washing machine, back wall and floor (using angle brackets). The decor end panel is 18mm thick MDF core. Will the decor end panel fixed as described be stiff enough esp along the outer vertical edge facing into the room, or would you advise stiffening it up (eg by reinforcing with another panel on the inside next to the washing machine)? Not planning to stand on the cantilevered worktop! Any advice and experiences gratefully received!
