Removing a bath for good

D13exile

I've a small pokey bathroom that currently has a very small shower cubicle, large washbasin, toilet and a large bath. It's a horrible grey suite installed back when the house was built in the mid 90's. I want to get rid of the bath as it hasn't been used in the three years I've lived here with my kids, which would allow me room to get a much larger shower cubicle and replace the washbasin and toilet.

I took the side panel off the bath last night to have a look at the plumbing. The pipework leading to the taps is a mixture of copper and plex measuring 20mm in diameter from what I could see. This appears to be an odd sizing as when I went online to look at isolator valves and stop ends to blank off the pipework (I might use the pipework in the future and so I want to be able to have the option to reuse it) when I remove the bath, 22mm appears to be the standard size for pipes of this diameter. So my question is, is my trusty tape measure wrong and that the pipes leading to the bath taps 22mm or was 20mm a standard pipe size back in the 90's?

Btw, I'm pretty good at DIY and also very short of cash which is why I'm doing this myself. However I believe in educating myself as much as possible before tackling anything. So any advice would be appreciated before I proceed.

They are irish instantor dimensions so you just need to get Irish instantor olives if you cant buy the Irish instantor fittings

22mm is European

I would say definitely get rid of the bath and install a decent size shower. More than likely the pipes feeding the bath taps are 3/4 inch, you could blank them off, or better go back to where they come from and change the fitting there so there is no longer water in them pipes.

Don't forget to do a proper job sealing the waste pipe too!
