I've been making progress and thought I'd post some more pictures
The first picture shows the units that I designed, I had the sink unit and the right-hand unit made, but they wanted far too much to make the drawer unit, so I'll make that one myself.
I've done the tanking, and fitted the units, I had intended to make the drawer unit yesterday, but can't get hold of any 18mm white chipboard, only local place that stocks it left their delivery in the rain all weekend 😳
I've also fitted the kick board under the units - I used white PVC Fascia board.
As I couldn't make the drawer unit I started tiling yesterday, being well aware of the implications of getting it wrong it was quite stressful laying the first couple of tiles, but they went down well, got six layed yesterday afternoon, should get the rest of the floor done today.
