There are many opinions of "It is desirable with the rest room vessel to install it independently." However, a proper rest room dimension to install a rest room vessel independently isnt being investigated fully. So, it was cleared about a rest room dimension to install a rest room vessel independently by this research based on two evaluation of a feeling of the use area and a feeling of the cleaning area. The results of the experiments were summarized as Mows : 1) It is B2 booth (950mm×1400mm) that a rate to feel "It is wide." exceeds 50%. 2) The space, which can be looked over when it sits down, is influenced only by the expansion of width dimensioa It can be said that more than the space quantity=0.75m^3 of B2 or more than width 1000 mm is desirable. 3) More than 1000 mm is desirable as for the width dimension when a distance to the rest room vessel from the toilet stool is taken into consideratioa 4) When cleaning is taken into consideration, an influence is taken in the width dimensioa Evaluation lowers when the width dimension is 900 mm. Therefore, as for the width dimension, 1000 mm is desirable.
