Question: is the back pedestal open
Document: This is the second Townsend pedestal sink I have purchased- one for our home and one for a motherin law apt. It is great quality. Beautiful, if you like a traditional look.
Just what we wanted, fit perfectly, shipped well protected in three sets of nesting boxes. No problems installing or connecting.
