We recently completed an update to ours. When beginning the process, I visited several Kitchen/Bath shops and viewed on-line offerings. Candidly, I didn't see anything I liked that I judged worth the cost.

My DH took measurements and drew a plan which we discussed with a local cabinet maker who has previously built cabinets for a neighbors kitchen. You can see our finished bathroom at a posting "Updated Master Bathroom" active on this forum.

The frame is solid maple and the panels are 3/4" and 1/2" cabinet grade maple plywood. It's very substantial and exactly like we wanted.

If you have a local cabinet maker, speak with them. Price, about half and significantly better materials. Only edge a factory cabinet may have is better finishing capabilities.

My thoughts, hope it helps.
