Slippery baths are the worst, even without additional balance/support issues.
Can confirm the chair looks the dog’s doodah and is v stable, also seems quite wide, which might be a consideration in some spaces. Great, unless you benefit from a higher back (Thing2 uses a stool when away from home, so is fine). What a great thing for IKEA to design.
Since I discovered, when replacing the grippy feet, that traditional shower chairs are merrily rusting away inside the legs, I’ve replaced ours annually anyway, so have just brought that cost forward a couple of months, and probably reduced it a bit, at £29.
