Our kitchen is a very long work in progress so always evolving. Recently we decided to change our 900mm base cabinet to 3 drawers to match the set next to it and utilise the space more. Unfortunately I think you need to buy the whole set including the carcass to get the drawers so I decided to DIY instead.
Steps
Step 1
Using our existing 450mm Kaboodle 3 drawer cabinet, I worked out what size panels I'd need for a 900mm unit then put all the dimensions in a cool website I came across that optimises your cutlists (hope it's ok to post the link as it was a game changer for me). This worked out that I'd only need 1 sheet of melamine to get everything I needed and also allowed for blade thickness.
Step 2
My first step installing was to empty the cupboard and remove the shelf and shelf pins. Then using the 450mm 3 drawer cabinet as a guide again, I added the 3 drawer runners to each side at matching heights. I picked up a Kreg drawer slide jig a few years ago so put it to use here. I'm afraid I forgot to take photos of this process.
With everything cut to size and ready to go, I assembled each drawer with 50mm chipboard screws just like the Kaboodle kits.

Step 3
I ironed edging to the top of the drawers to dress the edges and followed directions on the packet to trim the excess off.
I tried adding the edging before assembly on the second one but found it easier to do after because I didn't have to hold the individual pieces upright while ironing/sanding/trimming.

Step 4
The final step was adding the drawer slides. I removed the ends of each slide and fixed them to the bottom of each drawer side.

Step 5
The final step was a 2 person job due to the width of the drawers and especially the weight of the bottom one. I had to rope hubby into helping me load the sliders.
The hardest part of this job is yet to come - hubby and I agreeing on what panels and handles to finish this off. 😅
