OXO Good Grips Silicone Shower & Tub Drain Protector 11cm Dia. 5 "Works perfectly" Mrs Bowen 18 February 2021 Fed up of my shower getting blocked by my long hair, I decided to give this a go. I’ve tried different ones in the past, they either don’t work, or float away and don’t stay where they are supposed to. This one doesn’t have any of those issues and I suppose the only drawback is that I have to collect the hair that gathers around the outside of the protector - but at least it’s not going down the drain. It fits over the current sliver ‘plug’ on the shower base and looks neat and tidy. It’s certainly a lot greener compared to having to pour chemical unblocker down the drain every so often.
