All Chris Loves Julia parts are 3/4" thick, have a thermofoil topcoat and MDF core, and are made in the USA. Shaker rail/stiles are 2.5" wide. CLJ panels are flat/slab-style and 3/4" thick (Ikea's are typically 5/8").
When installing, Semihandmade base, tall and wall panels are made to run straight to the floor and slightly past or "proud" of the door/drawer fronts for a more custom, built-in look (see the Installation Manual for more details).
Please Note: 5" drawer fronts only come in slab options.
