Floor Mud Buying Guide
This guide helps you turn your floor mud calculator result into a cleaner purchase plan. Use it when you want fewer return trips, better waste assumptions, and a more realistic cart.
Step 1: Calculate the slope
A shower pan must slope 1/4 inch per foot toward the drain. The mud bed will be thin near the drain and much thicker at the walls. Calculate volume using the average depth.
Step 2: Buy specific 'Dry Pack' or 'Sand/Topping' mix
You cannot use standard concrete mix with gravel for a shower pan. You need a mix of sand and Portland cement (often sold as Sand/Topping mix or Deck Mud).
Step 3: Keep it dry
When mixing, add very little water. The consistency should feel like wet beach sand that holds its shape when squeezed. It should not pour like liquid.
Floor mud cost planning rule of thumb
The sand/topping mix is cheap. The real costs are the PVC shower pan liner, metal lath, curb forms, and the liquid waterproofing membrane applied on top.
