Slider Shower-Commode Chair Wanted

[KLD]

I am looking for a used slider type shower/commode chair to use when my mother comes to visit my new home (it has a tub and I want to avoid having to put in a roll-in shower for their visits which are only a couple times a year).

I am looking for products similar to these:
