Buying Guide

Float material

Magnesium floats are common for pan work because they resist rust, provide a smooth finish on cementitious mud beds, and balance weight and durability

Blade size and profile

Choose a 16-inch blade for efficient coverage on shower pans; a slightly narrower or beveled edge helps get into corners and along curb transitions

Handle comfort and grip

Look for ergonomic hand grips and secure fastenings to reduce fatigue during repeated passes and to maintain consistent pressure for an even pan slope

Weight and balance

A float that’s too heavy can overwork mortar, while one too light may not flatten consistently—magnesium models typically strike a good balance for troweling and finishing

Durability and brand reliability

Reputable masonry brands and cast construction reduce the chance of warping or edge damage, extending tool life for repeated shower-pan projects
