I bought this so that I could use it in the future even if I change to a drum-type. The rack is made of poles, so it could also be used as a temporary towel rack. (It is recommended that two people install it.) The thickness of the support pillars is 9.5cm, so it is sturdy, but it gives the impression of being larger than I thought, and there is a slight sense of oppression. If you want to make it look neat, I think a rack that doesn't extend is better. The length of the waterproof pan was 75cm, but it was quite a tight fit when I installed it. The actual width is listed as 72cm, but I think it's better to choose a place to put it with a few extra centimetres to allow for the thickness of the support poles.
