Need to take approx 10mm off the bottom of the new bath panel.
Any tips on how to do it proper?
What's it made of and does it have prefinished edges?
Plastic & no, don't think so.
Router with a guide bearing running along a straight edge would be my choice but run slow so it doesn't melt the plastic.
(I am not a professional)
Plastic bath panels are a royal pain in the hoop to cut. Plumbers generally hate them in my experience.
You can score it with a stanley along a straight edge and try and break it cleanly. It might, it might not.
If you want to be sure of getting it right, put some masking tape along both sides, mark your line and cut it with the finest toothed saw you can lay your hands on , like a tenon saw. if your able to clamp it witha length of timber either side to stop it wobbling as much as you can then all the better.
It still might split perpendicular to the cut.
Maybe try a Dremel?

That's what i'd go with but use a Japanese pull saw. The Irwin one for about £12 is pretty good
Get a local scout group to do it....
We have a plumber who cuts them with tin snips if you're feeling brave.
I've done it with a Dremel before. It was a bit of a pain and took quite a long time, but looked OK in the end.
How about one of those hacksaw handles with a fine toothed hacksaw blade.
Or a mini circular saw with a fine toothed wheel?

Brilliant...
How visible will the bottom cut be? I cut mine with a normal hand saw, then used file to take off any burred bits. The panel had silicon along the bottom so any imperfections are hidden, but it did a pretty good job.
An excuse to buy a festool type thingy.
I bought one from Aldi, was only 15 quid as I had the battery from the chainsaw of the same range. Brilliant wee thing.
Raise the bath 10mm using the supports underneath, redo the silicon seal, job done?

Possibly - but a bit hit and miss with plastics - with risks of either melting them or shattering them.
Chainsaw. Then silicon.
Buy a wooden panel the right size. Hth.

Which thingy? They make a lot of thingies.

Came here to say raise bath 10mm but got beat.
Is the panel takeoffable? Have you got it off?
If so, sandwich the plastic between two sacrificial lengths of wood clamping together tight, then cut with either a circular saw or a jigsaw or a handsaw, but take your time and a finer toothed one would be better.
If the panel is in place and not really takeoffable, I would probably lay a 10mm spacer down and use a flat bladed multi tool and very gently run it along the spacer.
Or chainsaw as above then silicone.
Scissors will cut it cleanly.
Two ways in my eyes
1)Masking tape, and a fine hacksaw blade. Took me ages
2) Groove the floor boards, 10mm may be a bit to much to router
Thanks for the tips! It's a corner bath panel so makes it a little trickier..
Scrap the plastic panel and get a sheet of moisture proof MDF bead n butt board. This is generally available from builders merchants and white primed finish.
Plastic bath panels tend to split/tear and notoriously tricky to cut cleanly. I’d love to watch the dude with scissors!

Its a great saw but it would rip the panel to shreds! Teeth need to be way finer than that. A tenon saw flat on the face with a timber fence would be my choice so you are cutting a groove rather than risk catching the plastic as it pulls through.
Or
You can get a special plasti cutting stanley blade that scores rather than cuts a groove. They're called laminate trimming blades. Coupl of passes with that mught work.
Quick update:
Managed to do it with a jigsaw with a very fine blade. The panel was about 5mm thick so the jigsaw did it perfectly, nice straight cut and took the small burrs off with a file.
Rather pleased with myself as it was a complete bitch to fit..
