Tomb B is a mud mortar brick structure. Its square plan measures 27' 9" externally and 21' 7" internally. The tomb has three arched openings on the east, south and north side. The interior and exterior are ornamented with alternating bands of mortar bricks, glazed bricks and glazed tiles. These bands become more detailed around the three arches to create the effect of highly articulated frames. The mehrab is located on the west wall. Simple squinches of three-tiered arches in the four corners transform the square lower storey into an octagon, which becomes the drum or base of the dome. The tomb is in a bad state of decay with most of its dome structure in ruins.
