The two-tiered custom storage shelf behind the tub features a larger wooded box below and a small shelf on small wooden legs above. The idea was to store extra towels and larger items in a basket below and behind the tub, while using the smaller shelf to place small bathing items. The shelves both are topped with the same copper flecked granite used for the vanity, as well as the same cherry wood stain. The finished piece is blends together nicely with the entire new guest bathroom.
