Glade Bathtub

Taken all the way down to base materials, one Glade Bathtub is 2 crafting steps deep and needs 4 intermediates — Spruce Lumber ×4, Rosewood Lumber ×3, Yew Lumber ×3 and 1 other — which resolve to 5 distinct raw materials totalling 42 units, plus 50 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,260 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 31 Wind Shard, 12 Wind Crystal and 7 Ice Shard.

Every step is Carpenter work, from a Lv 12 intermediate up to the Lv 50 finish, so one class covers the whole chain.

All 5 raw materials are gathered, and one of them is time-gated: Spruce Log (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Rosewood Lumber has the widest use: 83 recipes call for it, spanning seven of the eight crafting classes.
