most builders merchants stock manhole covers and frames either in steel or grp.

Do you intend to concrete a shower tray in or do the instructions say bed the tray on sand. If your fitting an acrylic tray onto a plywood base then to bed it on builders sand is the answer.

Can I also ask at what depth are you burying the cable and what precautions are you taking concerning the protection against damage.
