A hookah table is a table designed to increase the safety around socially smoking hookah. The hookah table includes a table, at least one hookah apparatus, a control panel, a central processing unit (CPU), and at least one heating element. The at least one hookah apparatus is mounted to a table base of the table. The control panel inputs control signals that are processed by the CPU to control the at least one heating element to vaporize intrinsic compounds within a smokable substance. The user inhales the vapor from the smokable substance through the at least one hookah apparatus. The control panel is externally integrated into a table top of the table, opposite to the table base. The CPU is internally mounted to the table top. The at least one heating element is selectively mounted to a corresponding hookah apparatus to heat the smokable substance.

A concealed bridge assembly is provided for supporting adjacent lateral edges of cooktop units that are mounted in a kitchen countertop. The concealed bridge assembly can be used for traditional raised mounting of cooktop units or true-flush mounting of cooktop units. When used with traditional mountings, the concealed bridge assembly has a top that is sized to be flush with the countertop surface and the approximate length of the countertop opening. If true-flush mounting is desired, the top of the concealed bridge assembly is flush with the top surface of a kerf cut in the countertop.
