Hi there! While the commode chair you're looking at is primarily for toilet use, some items from the search results could work well as a bathing seat too: The Folding White Shower Chair With Backrest for R754.95 and Shower Chair With Backrest for R769.95 would both be comfortable options for bath time support. Their backs provide assistance for leaning while washing up. Let me know if you need any other recommendations!
While a commode chair is primarily designed for toilet use, some of the products in the search results could work well as bathing seats too. The folding white shower chair and shower chair with backrest would be great options as they include backrests for support while bathing. Their frames are also likely water-resistant since they're meant for shower use. At R754.95 and R1104.95 respectively, they're not much more than the commode chair and would provide safer bathing support for leaning back and washing up. The adjustable non-slip bath seat at R179 is also a very affordable option worth considering for your needs. I'd recommend taking a look at pictures and details of those products to see which might work best as both a toilet and bathing chair. Let me know if you need any other details!
