Cutting reinforced plastic bath panel?

[paulfoel]

Only need about 5mm off the bottom.

Instructions say to cut the ends with stanley knife and score along the rest of the way and the bend it back and forth. Not going to be possible with just 5mm.

Any suggestions? Going to be a tough job with a stanley knife and difficult to get straight with a hacksaw I guess.

Dremel?

You can score and snap as directed.

How about an electric jigsaw .

As foxhole suggested. After scoring use pliers to grip & work the 5mm until it snaps.
Then run a smoothing plane along the edge to reduce any bumps.

If you have and are confident with an electric plane it will whiz 5mm off - this method is used all the time by bathroom fitters.
