Never used with a mat. Assembled once and stored in a dark place. Has not been used in the bath. The latest model number is 7233, so this is an older model, but it is clean with no rust. However, there is some dirt on the rubber feet, possibly due to aging. If you are concerned, it seems that they can be replaced like the seat cushion pads. Please check with a specialist. The product's outer box will be used for packing, but it also has some dirt due to aging. Please understand.
