So you would have to use PEX pipes, right? Otherwise, you won't be able to tug in the pipes under the floor.

This little kzfaq.infoUgkxVoi3B4CB6Oygq1-vo4OTL1M_M5JkrXif tub works perfect in our 6 x 6 shower and is easy to get in and out. Also easy to drain.

What brand is this- this is the most rugged baseplate I've seen?

Looks like you had a lot of play with those pex lines there

How to change those two pipes inside faucet

Might want to point out that the cover plate has to be installed before anything else.

Can anyone tell me how to change out the water supply lines from old copper ones to flexible ones for one of these free standing tub faucets. We recently removed an old 1980s Jacuzzi tub I want to replace it with a freestanding tub but the plumbing is old underneath and out of date plus it’s all copper and bent in weird positions

Not good explanation...you have to do better..
