Secure Roll Top Bath to Floor

Hi

i've got a roll top bath like the one here:
https://soak.com/en-gb/hotel-collec...-roll-top-bath---white-ball-feet/2001109.html
If you look closely at the picture, the feet are stood on small circular pads.
The bath is stood on a tiled floor. The problem I've got is that the bath moves really really easily - a slight push is enough to move it and so I'm worried I'm going to get leaks at the joins get wiggled about. A plumber fitted the bath and I can see he put a bit of silicone under each foot but this hasn't worked - all 4 feet can move freely now.

So I've got 2 ideas for how to fix it to the floor, I'd be interested to hear people's thoughts:

Idea 1)
Drill through the feet with HSS drill bit and then through the tile with tile drilling bit and put a screw through each foot into the wooden floor.

Idea 2)
Use some sealant remover to get rid of as much of the silicone as possible and then try again using something better to 'glue' the feet to the tile. Found another thread on here that suggests CT1 or Sika EBT or GB Pro would do it. Alternatively maybe just Gorilla Glue?

Any suggestions would be welcome
Cheers

Obviously a lightweight repro bath - Maybe, just maybe mark the positions of the small round feet - then use a diamond tile holesaw (or 4) to cut through the tiles and allow the feet to sit on the floor below. Have some spare tiles if possible.

yes it is very light, so when empty it is very easy to move.
I'm not sure about cutting sections of the tiles as the tiles are obviously fixed to the floor so it would probably end up having to break it out with a hammer and chisel, which would then risk damaging the surrounding tiles

Double sided adhesive foam pads?

Also has anyone ever tried using CT1 to secure something to a tiled surface? I've actually got some spare tiles left over from the bathroom floor so I could get some CT1 and do a test I suppose

Manufacturers never seem to get their thinking right when it comes to re-manufacturing these types of things out of modern lightweight materials.

Old roll top baths were cast iron or steel making them heavy enough to sit on their own without the need to secure. That being said, claw and ball feet on a roll top bath were never designed to sit on tile. Unless the tiler was exceptionally good and tiles designed to take point loading, then there always a danger of damage/cracking when the bath's full. Seen it happen a few times.

@Nige F is the best way, you can then secure the feet to the wood with screws, rather than them sitting on the tile itself. Once cored then a little diamond blade on a dremel, cut the piece into segments and a small screwdriver will prise the pieces out.

Next option would be to make 4 little wooden plinths for the feet to sit on, they can be cut and modeled/stained to be a feature.

Adhesives could work short term but wouldn't rely on it longer term, especially with such a small footprint.

Mark position of feet on tiles. Drill holes maybe 20mm into tiles, use nail first to centre punch tiles, then 3mm, 6 10 14 and final 20mm drill bits to drill tiles to wood floor. Find round stainless steel or metal bar insert and use gorilla double sided tape to hold everything together.

Or just use the gorilla double sided tape on tiles. Cleaning well first with thinners
