πŸ’‘ How to Calculate Mortar Bed Material

Mortar bed thickness determines the type: thinset (1/4 inch or less) for flat surfaces, medium-bed (1/4 to 3/4 inch) for slight leveling, and thick-bed/mud bed (3/4 to 1.5 inches) for significant leveling or shower pans.

A 50 lb bag of thinset covers about 95 sq ft at 1/4 inch with a 1/4Γ—1/4 inch notched trowel. Coverage decreases proportionally with thicker applications. Large-format tiles (over 15 inches) require back-buttering.

A 50 sq ft shower floor with 3/4-inch thick mud bed: coverage per bag β‰ˆ 8 sq ft. Need about 7 bags of 50 lb mortar = 350 lbs.
