Just fill the gap with grip fill, the bath wont move then, ever. Then put a nice bead of silicon around it in about ten minutes and in the time you’ve saved poncing about jacking up the bath or removing it, feck off to the coast in the camper for a lovely day out and an ice cream. It’s much more fun.

PS. There’s a reason my business is called Griffin Heating and not Griffin Plumbing & Heating, can you tell?

 

What’s the bath made of? Metal baths flex far less locally than even the thickest plastic ones.

Is there anything under its legs, or is it straight on to floorboards? Is all of that sound, nothing has moved?

 

Fill the bath with water to weight it down first and see if you can get it nearer the wall

 

Would it be necessary to pee in the expansion tank as well? Would like to get a professional view.

 

Assume you're asking for that "friend" again!

 

In these situations I believe it would be rude not to pee in the cold water storage tank. That way they get the delicate aroma of Stella Artois when taking a bath. And who doesn’t like that.

I’ve you can put up with being smelly. I’d leave it until the morning

 

Can you do Badedas if I pay extra?

 

Definitely the morning, no issue leaving it to cure properly.
