Hi folks, apologies if this is a simple question. I have fitted myself a bath before and somehow I luckily ended up getting the right bits and it hasnt leaked yet! I need to fit a bath in my new house and was wandering what flexi connectors I need to connect to the taps. I know the 15 and 22mm relates to the pipe size, but not sure what the bore is. Which do i need to connect my 15mm pipe to bath taps, they do all these??:

15mm x 1/2" 10mm
15mm x 1/2" 13mm
15mm x 3/4" 13mm
15mm x 15mm Stand Pipe 13mm Bore
15mm x 15mm speedfit 13mm Bore
22mm x 3/4" 13mm Bore

thanks in advance

15mm x 1/2" 10mm

15mm = Size of Pipe
1/2" = size of taps
10mm = Size of Flexi Pipe

The difference between the two that you mentioned is the bore of the flexi pipe, the bigger the better as a smaller bore will increase resistance and therefore reduce pressure.

Yes basin taps are 1/2"

Bath taps are 3/4" mate so 15mm to 3/4 or 22mm to 3/4
