Securing basin pedestal and toilet through laminate floor?

[ray99]

Hi there. been tiling the bathroom the fitting a new suite. Now fitting TILELOC tile effect laminate flooring by FLOORMASTER to the bathroom. Very small room so fitting the boards across ways which means a full board trimmed slightly goes all the way left to right. Have removed the skirting board on the right and using rebated baton on the left so the board goes under the bath panel. Door frame has been undercut so board fits under that. I therefore have plenty of expansion space left and right and at the hall end but at the window end is it ok to screw the toilet and the basin through the laminate and into the floor as this would hold that board rigid.
Thanks.

Keeping expansion gaps everywhere to allow natural movement and then screwing the lot down makes all the other gaps useless.

Not screwing it all down, just into the last board. Got to secure the toilet and basin pedestal somehow. Laminate is 8mm thick. Could I secure into that without going through to the floor boards if I bedded the pedestal etc in silicone?

What we normally do with wood-engineered (10, 15 or 20mm thick) is install the board just a little bit underneath the pan. The pan is then installed back, resting on the bit of board. We seal the pan/board with transparent silicon - we never screw anything in the wooden floor.

Ah right. So install the floor, set the pan in place and draw around with a pencil. Remove that section of flooring and cut around about 1/4" or so inside the line. Refit the floor and bed the pan in clear sanitary sealant. The screws holding the pan will now go straight into the floor, missing the laminate. The laminate can then move a little if it wants.
Makes sense. Easy when you know how. Thanks.

Set sanitary in position, drill for fixings, remove sanitary bits, enlarge holes, fix bits in place. Holes need to be 6 - 10mm bigger than screws so that the screws have a gap around.

Strangely enough I had thought about doing that just before I read your post. That sounds a better way of doing it.
