General Modernizer installs zero-entry curbless showers throughout Nassau County, NY. A curbless shower is not a prefab insert. It is real construction: subfloor modification, waterproofing membrane, precision slope work, and linear drain installation.
What curbless means: the shower floor is flush with the bathroom floor. No raised lip, no curb, no step-over. Water is contained by a sloped floor that directs it to a linear drain. This eliminates the step-over that causes most shower-related falls and allows walkers, rollators, and wheelchairs to roll directly into the shower.
The four construction problems that separate a real curbless shower from a leak waiting to happen. First, subfloor preparation: to achieve a flush entry, the shower floor must slope toward the drain at one quarter inch per foot. In most Nassau County homes this means recessing the subfloor in the shower area or building up the bathroom floor outside the shower. Both require structural carpentry work before any tile is installed. Second, waterproofing membrane: every curbless shower General Modernizer builds uses the Schluter-Kerdi bonded waterproofing system, a fabric-reinforced polyethylene membrane applied to the entire shower floor and walls before tile. Without a bonded membrane, water migrates through grout joints and behind tile, causing mold, substrate failure, and structural damage. Third, linear drain placement: a linear drain along one wall allows large-format tile with a single clean slope direction. Center drains require four-direction slopes that create complex cuts and visible grout patterns. Fourth, slope precision: the one quarter inch per foot slope must be consistent across the entire shower floor. We use a laser level to verify slope before and after tile installation.
Design options: linear drain in matte black, brushed nickel, or polished chrome. Large-format tile (24x48 or 24x24 porcelain) on walls and DCOF-rated tile on the floor. Frameless glass enclosure in clear or low-iron glass. Roll-in open design for wheelchair users. Built-in tiled bench seat at 17 to 19 inches high. Structural grab bars in designer finishes matching the drain and glass hardware.
Cost: $12,000 to $18,000 installed in Nassau County for a complete project including subfloor preparation, Schluter-Kerdi waterproofing, linear drain, large-format tile, frameless glass, bench seat, and structural grab bars. Projects with plumbing relocation or doorway widening add $2,000 to $4,000. Nassau County permit handling included. Most installations take 5 to 8 business days.
