You can easily take a bath in a deep bathtub with a "step stool" - Manufacturer: Panasonic - Size: 37.5cm x 30cm x 5-step height adjustment - Height: 5-step adjustment: 12, 14, 16, 18, 20cm - Weight: 3.2Kg for stable support - Care: The dark brown cushion can be removed - With instruction manual Product information from the manufacturers: ① https://www.aronkasei.co.jp/anju/products/nyuuyokukaigo-yokusoutesuri/533687/ ② https://sumai.panasonic.jp/agefree/products/bath/yukuria/yokusoudai_soft/pn-l11620.html My purchase prices were: ① 24,772 yen, ② 18,700 yen (Both purchased at DCM Homac one year ago) Thank you for viewing. I believe the best combination for safe bathing when your legs and back become weak is: "① + ② + (also listed) Bathing chair with backrest". It should also make it a little easier to watch over your parents while they bathe. Please consider it.
