I'm looking for some advice on where to locate the join in a (quartz or granite) worktop. There is also a large island going in so this is not the only worktop

 

The run is for a 4.2m worktop with a cutout for a 800mm sink in the centre. Therefore the choices are for a single join in the middle of the sink or three separate pieces with two joins.

 

The glass splashback we're going to have will have two joins (1 x 1600m, 1 x 1000mm, 1 x 1600mm ), so lining up with these is an option, but this would add some risk with ensuring that the alignment is spot on. The other option is to have two joins elsewhere ( 3 x 1400mm?)

 

The sink we're looking at is mounted and supported underneath so there are no particular structural integrity issues, just the asethetics.

 

Any advice or experiences most welcome

 

Regards

Do you really need two joins if not centred on the sink? We have a 5m run of granite worktop with a fairly centrally positioned sink and only one join (away from the sink) but I believe our supplier can do 4.2m as a single slab.

I always put joints where the sink goes. I biscuit cut slots in the joints and epoxy glue 2p coins in the joints for additional support.

Personally I would try and arrange my kitchen such that there was a natural break in it.

Keep the joins away from the sink for both structural integrity and to eliminate the remote possibility of a leak at a join.

 

Ideally position your joins on carcases and if this moves it closer to the sink thats fine. Do not at whatever cost put the join on the sink. you will regret it.
