glass block cost
Assuming you pay $10/sq. ft. for materials installed at $20/sq. ft. on 50 sq. feet of vertical wall, that's a total estimated cost of $1,500. Hiring a pro to build a 4 foot x 6 foot glass block wall (for use in a shower or as a room divider) might cost $2,000 to $3,000. A glass block bathroom window costs $400 to $500, including labor and materials.
