PROBLEM TO BE SOLVED: To provide a structure of mounting a bathroom floor to be surely grounded on a structural bed without associatively locking a waterproof pan supporting bolt to a lock nut. SOLUTION: The structure comprises a supporting leg cylindrically protruded on the lower face of a waterproof pan and having a female screw threaded in the cylindrical inner face, a through-hole formed right over the female screw, through which a tool turnable around the supporting leg can be inserted, a supporting bolt having a top formed with an engaging portion to be threaded to the female screw for engaging with the tool, and adapted to be threaded up and down to the supporting leg for adjusting the height of the waterproof pan, a lock nut having a top provided with an engaging portion externally threaded to a portion of the supporting bolt extending upward from the supporting leg for engaging with the tool, and adapted to be threaded down and thrust by the supporting leg for locking the supporting bolt, and a washer held between the lock nut and the supporting leg for producing a sufficient friction force on the face abutting on the lock nut and the supporting leg to prevent the rotation of the lock nut accompanied by the rotation of the supporting bolt.
