Hi guys, yesterday I ripped my bath out to replace with a new shower cubicle I purchased. All plumbing etc has been done and in working order.
Upon ripping it out I was greeted with the attached. I understand the reasoning for this because of access to pipework. But now I need to claim part of this floor to actually walk on.
I'm wondering what to fill it with etc without obstructing the pipework but also something strong enough to support weight. Any advice would really help me out!
