Hi, what is the size of a single Belfast sink ? Are they all a standard size ?
Most modern, metric Belfast sinks are 595mm x 460mm x 255mm or approx 23.5" x 18" x 24." Occasionally 590 in width, 455 in depth an/or 220mm. Check your opening first but most single Belfast sinks will fit in standard openings. Take care if you purchase an imported imperial one. 24" may be a shade too big for the opening.

Am trying to replace 2 kitchen basket waste strainers, top diameter 115mm, with overflow - but with 60mm unthreaded outlet which connects directly into a right angled connector with 45mm diameter pipe. No maker's name, probably dates from around 2003/4. Have tried 4 plumbers' merchants without success - any ideas?? Or should I just give up and replace pipework??
Hi Rod and thanks for visiting SinkAdvice.co.uk
This sounds like a bit of a puzzle and obviously I can't see the parts but we can break things down to get some clarity. Firstly 115mm flange ( top) diameter should be fine and is about right for a basket strainer type waste. Secondly, you say it has a 60mm outlet. I am assuming that you measured this with a tape. This is where a lot of confusion creeps in. Threaded parts in plumbing, even abroad and including sink wastes are almost always imperial BSP (British Standard Pipe.) The measurement relates to the bore not the thread size. Best I can work out is that your threaded outlet is 2" BSP which gives an external diameter of 2 1/4" or 59.614 or near as damn it 60mm. Still it is unusual for a 2" outlet as they are almost all 1 1/2 ". Lastly as for the 45mm pipe. These days the equivalent of the old 1 1/2 pipe has tended to standardise to 42mm for solvent weld and 40mm for push fit. Years ago it was not so straightforward and different manufacturers used slightly different diameters.
I would give up on trying to find 2" outlet wastes, I can't remember seeing any. Despite all this there seems to be a relatively straightforward way around the problem but you will need to buy new traps. Fit two standard basket wastes with 1 1/2 " outlets e.g. https://www.screwfix.com/p/sink-strainer-waste/74806 and traps to suit If is is a double sink something like this https://www.screwfix.com/p/mcalpine-double-1-bowl-sink-kit-white-40mm/7178 Use standard 40mm pipework until it meets your existing pipework then just use a compression waste fitting to join the two together e.g. if it's a straight fitting https://www.screwfix.com/p/floplast-wc08-universal-compression-waste-straight-coupler-white-40mm-x-40mm/11980 This should fit your 45mm pipe, if not this will https://www.screwfix.com/p/floplast-wf08-flexi-waste-straight-coupling-grey-38-45mm-x/81383 but in my opinion is a less ideal solution.
I hope this all makes sense but feel free to get back if you need clarification or any other information. I have used screwfix as an example but these parts are readily available at most diy or plumbing outlets.
