You need to explain that a bit more.

Marine ply is waterproof. you don't need to seal it. What sheeting are you talking about?

It's a plastic sheeting used instead of tiles.
My job has me in 6 to 8 showers per day & I hate this stuff. Unless the ply is a half inch thick you won't have grounds to screw anything in. Especially an electric shower or shower pole.
OP if I may suggest tiles are a better finish. The sheeting is no more waterproof than tiles but tiles are a better job.
Most sheeting I see is in rented accommodation.

Marine ply is good but personally cement board is better for a shower enclosure . Regardless of which is used it's a good idea to tank the shower enclosure to waterproof everything before tiling or in this case sheeting with PVC. Tanking kits are available in most decent tile merchants and consist of a edge and corner sealant tape along with a bucket of rubber type paint. Expensive enough stuff but worth doing right as water ingress is a disaster.

You must have a lot of cowboy plumbers that do not put in grounds in the first fix installation. Plumbers with 20 years experience do.

I'd see it in rented accommodation mostly. The type of landlord that takes stuff out of skips for his tenants. He's the type of landlord that does all the repairs himself.
Putting in grounds for a shower is good but not perfect imo. If it's sheeted with thick enough ply behind all of the pvc you have grounds for anything you want. The shower or shower pole can be moved in years to come if needed or even just to know there are grounds to put up soap dish (no longer provided with most showers)

Anyone install this over tiles? I'm going to do this but not sure about the Base, the tile sealing trim is pertruding so do I cut away this trim before putting the pvc Base trim down.

I've used plastic tile sheeting directly on plasterboard and it was fine. I used Evo-Stik Nail and Seal as the adhesive and an ordinary silicone sealant on the edges and joins.
I've never used it on plywood but I can't see why you'd need to seal marine ply, if the sheeting is done properly then no water should get through to the base.

It definitely doesn't look as good as tiles, and you can get discolouration with age on the white versions, however, it's very quick to install and it's cheap.

I'd bite the bullet and remove the tiles and trim altogether but I can understand why you mightn't want to do that. You can test the adhesion on tiles with the adhesive mentioned above and a piece of smooth pvc.

Online & in the hardware shop they say its ok to place over Tiles. The tiles were placed on regular plasterboard & now leaking through. When I removed some of the tiles the plasterboard was brittle & broke a hole into very easily. I think the easiest way & cheapest is to put the tiles back on & use the PVC boarding.
